iShares Bitcoin Trust ETF

The trading prices of many digital assets, including bitcoin, have experienced extreme volatility in recent periods and may continue to do so. The average annualized one-year trailing volatility of bitcoin over the past ten years to date remains elevated at 64.02%. Over the course of 2021, there were steep increases in the value of certain digital assets, including bitcoin, and multiple market observers asserted that digital assets were experiencing a “bubble.” These increases were followed by steep drawdowns throughout 2022 in digital asset trading prices, including for bitcoin. In the 2021-2022 cycle, the price of bitcoin peaked at $67,734 and bottomed at $15,632, marking a steep 77% drawdown. After reaching an all-time high of approximately $126,000 in October 2025, the price of bitcoin declined to below $60,000 in June 2026, representing a drawdown of more than 50%, and there can be no assurance that the price of bitcoin will not decline further. These episodes of rapid price appreciation followed by steep drawdowns have occurred multiple times throughout bitcoin’s history, including in 2011, 2013-2014, and 2017-2018, before repeating again in 2021-2022, 2024, and 2025-2026. Bitcoin has continued to experience significant volatility, and significant price declines, since late 2025. For example, bitcoin lost approximately 14% of its value according to some sources in mid-October 2025 as part of wider digital asset market turmoil, widely attributed to global trade tensions, which triggered a number of dislocations in the digital asset market (the “October 2025 Flash Crash”), including liquidations of up to $20 billion in collateral in the form of various digital assets (including, but not limited to, bitcoin) securing trades (particularly perpetual futures contracts and various forms of financing transactions), along with reported service interruptions, halted orders, forced unwinding of trades, and other issues, across centralized and decentralized exchanges. Digital asset prices, including the price of bitcoin, declined significantly during the first half of 2026, and during the second quarter of 2026, U.S. spot bitcoin exchange‑traded products, including the Trust, experienced their largest quarterly net outflows since such products launched in January 2024, according to some sources. As of the date of this report, the price of bitcoin remains significantly below its October 2025 all-time high, and digital asset prices continue to fluctuate significantly.

Extreme volatility may persist and the value of the Shares may significantly decline in the future without recovery. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. For example, in the first half of 2022, each of Celsius Network, Voyager Digital Ltd., and Three Arrows Capital declared bankruptcy, resulting in a loss of confidence in participants of the digital asset ecosystem and negative publicity surrounding digital assets more broadly. In November 2022, FTX Trading Ltd. (“FTX”), one of the largest digital asset platforms by volume at the time, halted customer withdrawals amid rumors of the company’s liquidity issues and likely insolvency, which were subsequently corroborated by its CEO. Shortly thereafter, FTX’s CEO resigned and FTX and many of its affiliates filed for bankruptcy in the United States, while other affiliates have entered insolvency, liquidation, or similar proceedings around the globe, following which the U.S. Department of Justice (“DOJ”) brought criminal fraud and other charges, and the SEC and CFTC brought civil securities and commodities fraud charges, against certain of FTX’s and its affiliates’ senior executives, including its former CEO. In addition, several other entities in the digital asset industry filed for bankruptcy following FTX’s bankruptcy filing, such as BlockFi Inc. and Genesis Global Capital, LLC (“Genesis”). Since these events, (collectively, the “2022 Events”), regulatory actions continued. In April 2025, the DOJ issued a policy memo ending “regulation by prosecution” for crypto actors, refocusing on fraud, illicit finance, and aligning enforcement with executive directives. Acting CFTC Chairman directed staff to follow the DOJ’s new policy, pausing certain prosecutions. In July 2025, BlockFi reached a $35 million settlement with the DOJ, clearing legal hurdles for creditor distributions. As a result of these events, the digital asset markets have experienced extreme price volatility and other entities in the digital asset industry have been, and may continue to be, negatively affected, further undermining confidence in the digital asset markets. These events have also negatively impacted the liquidity of the digital asset markets as certain entities affiliated with FTX engaged in significant trading activity. If the liquidity of the digital asset markets continues to be negatively impacted by these events, digital asset prices, including bitcoin, may continue to experience significant volatility or price declines and confidence in the digital asset markets may be further undermined. In addition, following the 2022 Events, regulatory and enforcement scrutiny of the digital asset industry increased, including from, among others, the DOJ, the SEC, the CFTC, the White House and Congress, as well as state regulators and authorities, and the digital asset industry remains subject to significant attention from regulators, legislators and policymakers. These events are continuing to develop and the full facts are continuing to emerge. It is not possible to predict at this time all of the risks that they may pose to the Trust, its service providers or to the digital asset industry as a whole.

In September 2026, Bitget, a digital asset platform, reported that a security breach resulted in unauthorized transfers of approximately $388 million in digital assets and the temporary suspension of withdrawals. According to reports from blockchain security firms, hacks and exploits across the digital asset industry resulted in approximately $768 million in reported gross losses during September 2026, some of which were subsequently recovered. According to the FBI, on October 29, 2026, unauthorized third parties transferred more than $6 billion in digital assets from wallets attributed to Binance, the largest digital asset trading platform by trading volume. Blockchain analytics firm TRM Labs characterized the incident as the largest theft of digital assets on record. A security incident involving a major trading platform may affect confidence in, and trading activity across, the broader bitcoin and crypto markets, including on the Constituent Platforms. Because the Index is based on prices from a limited number of Constituent Platforms, any resulting disruption on those platforms could affect the Index price. To the extent that bitcoin is compromised in a hack or is acquired by exchanging other stolen assets for bitcoin, that bitcoin cannot be frozen by an issuer, and any sale of that bitcoin in the market could exert downward pressure on the price of bitcoin. Such incidents, particularly one of this scale, may undermine confidence in digital asset platforms, networks and markets, adversely affect liquidity and trading activity, lead to withdrawal suspensions or other disruptions at digital asset platforms, increase regulatory and enforcement scrutiny, and contribute to volatility or declines in the price of bitcoin and the value of the Shares.

Market expectations regarding the administration, Congress, federal regulators, or future legislation or rulemaking may contribute to increases in digital asset prices or valuations. There can be no assurance that those expectations will be realized, that any enacted or proposed legislation or regulation will benefit the digital asset industry generally or bitcoin specifically, or that digital asset prices will rise or maintain their current levels. Delays in, changes to, or adverse developments relating to implementation of the GENIUS Act, enactment of the CLARITY Act or similar legislation, or other federal or state regulatory actions, including SEC and CFTC rulemaking, interpretations and guidance, could negatively affect market sentiment, liquidity, trading activity, or the prices of digital assets, including bitcoin. Any resulting decline in the price of bitcoin could cause a reduction in the value of the Shares and cause Shareholders to suffer losses. Moreover, there can be no assurance that political sentiments toward the digital asset industry, or market perceptions of those sentiments, will not shift over time.

On March 6, 2025, President Trump issued an executive order for the “Establishment of the Strategic Bitcoin Reserve and United States Digital Asset Stockpile” (the “Order”). The Order requires the Secretary of the U.S. Department of the Treasury (the “U.S. Treasury Department”) to establish two offices to administer and maintain a “Strategic Bitcoin Reserve” (the “Bitcoin Reserve”) and a U.S. Digital Asset Stockpile (the “Digital Asset Stockpile”), respectively. The Bitcoin Reserve is intended to be capitalized with bitcoin forfeited as part of U.S. criminal or civil proceedings or in satisfaction of penalties imposed by executive agencies. The Digital Asset Stockpile is intended to be capitalized initially with other digital assets forfeited as part of criminal or civil asset forfeiture proceedings. Following the issuance of the Order, bitcoin markets developed expectations that the United States may begin acquiring and holding bitcoin, which many viewed as a positive development for bitcoin prices. The Order directs the Secretaries of the U.S. Treasury Department and the U.S. Department of Commerce to develop budget-neutral strategies for acquiring additional bitcoin for the Bitcoin Reserve. Legislation was introduced in the U.S. Senate and the U.S. House of Representatives that would direct the acquisition of one million bitcoin by the federal government over a five-year period, to be held in trust in secure storage by the U.S. Treasury. The bill proposed funding the bitcoin acquisition using remittances from the Federal Reserve, revaluations of Federal Reserve gold certificates, and other mechanisms characterized as budget-neutral (such as transfers from federal agencies using bitcoin acquired through asset forfeitures). In May 2026, legislation styled the American Reserve Modernization Act of 2026 was introduced in the U.S. House of Representatives, which would, among other things, establish the Bitcoin Reserve and a Digital Asset Stockpile in statute and require the consolidation of digital assets held by federal agencies within the U.S. Treasury Department. On September 16, 2026, the House Committee on Financial Services approved the legislation, as amended, by a vote of 28–21, advancing it for consideration by the full House of Representatives. Bills were also introduced in several state legislatures to authorize the acquisition of bitcoin by state governments or their instrumentalities, some of which have failed to pass. As of the date of this report, these initiatives remain subject to significant uncertainty. While some administrative steps have reportedly been taken, there is no assurance that the federal government or any state government will announce or implement bitcoin acquisition plans, or that any such plans will meet market expectations. Even if government acquisitions occur or legislation requiring acquisitions is enacted, the price of bitcoin may decline if there are implementation challenges, unexpected difficulties, policy or legal reversals, or changes in political priorities, any of which may negatively impact Share value. Executive orders such as the Order are subject to change and can be reversed or overturned. The enduring existence and size of the Bitcoin Reserve and Digital Asset Stockpile, and the passage and implementation of legislation at the federal or state level, remain subject to complex challenges and uncertainty that make it difficult to evaluate their effect on the value of bitcoin and the Shares, now or in the future.

Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value. The Trust is not actively managed and will not take any actions to take advantage of, or mitigate the impacts of, volatility in the price of bitcoin.

Digital asset treasury companies risk.

Digital asset treasury companies are a relatively new phenomenon and it is difficult to predict their long-term sustainability, and therefore their impact to digital asset markets, and to the Trust. In 2026, certain digital asset treasury companies have experienced significant declines in their market valuations, which may limit their ability to raise additional financing to acquire digital assets, including bitcoin, or increase pressure to sell their existing holdings. Digital asset treasury companies may increase procyclical dynamics in the market because they may purchase digital assets, such as bitcoin, when prices are rising and they may in certain circumstances be forced to sell such assets when prices are decreasing, potentially causing downward pressure on bitcoin prices in a falling market (causing prices to fall faster than they otherwise would). Digital asset treasury companies could cause greater volatility in digital asset markets, including markets for bitcoin. Negative events or sentiment surrounding digital asset treasury companies could affect the market for bitcoin. The foregoing or similar events involving digital asset treasury companies could adversely affect holders of Shares in the Trust.

Digital assets such as bitcoin were only introduced in 2009, and the value of the Shares is subject to a number of factors relating to the capabilities and development of blockchain technologies over time, such as the recentness of their development, their dependence on the internet and other technologies, their dependence on the role played by users, developers and miners and the potential for malicious activity. For example, the realization of one or more of the following risks could materially adversely affect the value of the Shares:

exploited a firmware vulnerability affecting certain Coldcard hardware wallets to derive private keys and steal approximately $116 million in bitcoin without physically accessing the affected devices. The loss, theft, compromise or destruction of a private key required to access a digital asset may be irreversible. If a private key is lost, stolen, destroyed or otherwise compromised and no backup of the private key is accessible, the owner would be unable to access the digital asset corresponding to that private key and the private key will not be capable of being restored by the digital asset network resulting in the total loss of the value of the digital asset linked to the private key.

making it more difficult for transactions to be confirmed, increasing transaction costs, or affecting the Bitcoin network’s security, among other negative effects, any of which could negatively affect the value of bitcoin and consequently the Shares.

could adversely affect the value of the Shares.” If any of the foregoing were to occur, it could result in losses to Shareholders. In any of these circumstances, a malicious actor may be able to compromise the security of the Bitcoin network or take the Trust’s bitcoin, which would adversely affect the value of the Shares. In addition, because a significant amount of bitcoin is held in addresses whose public keys have already been exposed, a sufficiently advanced quantum computer could be used to misappropriate that bitcoin, even if the Trust’s own bitcoin were not compromised, undermining confidence in the Bitcoin network and depressing the price of bitcoin, which would adversely affect the value of the Shares. Moreover, the functionality of the Bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Shares.

A determination that bitcoin or any other digital asset is a“security”* may adversely affect the value of bitcoin and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.*

Depending on its characteristics, a digital asset may be considered a “security” under the federal securities laws. The test for determining whether a particular digital asset is a “security” is complex and difficult to apply, and the outcome is difficult to predict. Although certain public statements by SEC officials have suggested that bitcoin may not be treated as a security, such statements are non-binding and subject to change, and regulatory authorities or courts may reach a different conclusion.

On March 17, 2026, the SEC issued an interpretive release (the “Interpretive Release”) regarding the application of the federal securities laws to certain types of digital assets and certain transactions involving digital assets. In the Interpretive Release, the SEC stated that, based on its current understanding of the digital asset markets, bitcoin, is a “digital commodity” and not itself a security. Although the Interpretive Release represents the official position of the SEC, it is not itself a statute or binding rule, does not supersede or replace the Howey test, is based on the SEC’s current understanding of the digital asset markets, and may be refined, revised or expanded. In addition, a court, regulator, or future administration could take a different view, and future legislation, rulemaking, enforcement positions, judicial decisions or other developments could result in bitcoin, the Trust, the Shares or transactions involving bitcoin being treated differently than contemplated by the Interpretive Release. Any such developments could adversely affect the Trust and the value of the Shares.

On August 18, 2026, the SEC proposed Regulation Crypto Assets, which would establish registration exemptions for certain investment contracts involving crypto assets and a conditional safe harbor addressing when a crypto asset ceases to be subject to an investment contract. The proposal has not been adopted, may be revised or withdrawn, and does not address exchange-traded products such as the Trust. The Sponsor cannot predict whether Regulation Crypto Assets will be adopted or how these or other regulatory developments could affect digital asset markets, the price of bitcoin or the value of the Shares.

Notwithstanding the SEC’s current interpretation that bitcoin is not itself a security, a court could reach a different conclusion under existing law, or future legislative or regulatory developments could result in bitcoin being treated as a security under the federal securities laws. Any such determination or development could materially adversely affect the Trust and the value of the Shares.

The Sponsor may dissolve the Trust if the Sponsor determines bitcoin is a security under the federal securities laws, whether that determination is initially made by the Sponsor itself, or because the SEC or a federal court subsequently makes that determination. Because the legal tests for determining whether a digital asset is or is not a security often leave room for interpretation, for so long as the Sponsor believes there to be good faith grounds to conclude that the Trust’s bitcoin is not a security, the Sponsor does not intend to dissolve the Trust on the basis that bitcoin could at some future point be determined to be a security.

Any enforcement action by the SEC or a state securities regulator asserting that bitcoin is a security, or a court decision, to that effect would be expected to have an immediate material adverse impact on the trading value of bitcoin, as well as the Shares. This is because the business models behind most digital assets are incompatible with regulations applying to transactions in securities.

Moreover, whether or not the Sponsor or the Trust were subject to additional regulatory requirements as a result of any SEC or federal court determination that its assets include securities, the Sponsor may nevertheless decide to terminate the Trust, in order, if possible, to liquidate the Trust’s assets while a liquid market still exists. For example, in response to the SEC’s action against the issuer of XRP, certain significant market participants announced they would no longer support XRP and announced measures, including the delisting of XRP from major digital asset trading platforms. The sponsor of the Grayscale XRP Trust subsequently dissolved this trust and liquidated its assets. If the SEC or a federal court were to determine that bitcoin is a security, it is likely that the value of the Shares would decline significantly, and that the Trust itself may be terminated and, if practical, its assets liquidated.

Regulatory changes or actions in foreign jurisdictions may affect the value of the Shares or restrict the use of one or more digital assets, mining activity or the operation of their networks or the digital asset platform market in a manner that adversely affects the value of the Shares.

A number of foreign jurisdictions have taken regulatory action aimed at digital asset activities. China has made transacting in crypto assets illegal for Chinese citizens in mainland China, and additional restrictions may follow. Both China and South Korea have banned initial coin offerings entirely and regulators in other jurisdictions, including Canada, Singapore and Hong Kong, have opined that initial coin offerings may constitute securities offerings subject to local securities regulations. In May 2021, the Chinese government announced renewed efforts to restrict crypto asset trading and mining activities. Regulators in the Inner Mongolia and other regions of China have proposed regulations that would create penalties for companies engaged in crypto asset mining activities and introduce heightened energy saving requirements on industrial parks, data centers and power plants providing electricity to crypto asset miners. The United Kingdom’s Financial Conduct Authority published final rules in October 2020 banning the sale of derivatives and exchange traded notes that reference certain types of digital assets, contending that they are “ill-suited” to retail investors citing extreme volatility, valuation challenges and association with financial crime. The United Kingdom’s Financial Services and Markets Act 2023 (the “FSMA”) received royal assent in June 2023. According to publicly available government materials, the FSMA brings digital asset activities within the scope of existing laws governing financial institutions, markets and assets. In addition, the Parliament of the European Union approved the text of the Markets in Crypto-Assets Regulation (“MiCA”) in April 2023, establishing a regulatory framework for digital asset services across the European Union. Certain parts of MiCA became effective as of June 2024 and the remainder became effective as of December 2024. MiCA is intended to serve as a comprehensive regulation of digital asset markets and imposes various obligations on digital asset issuers and service providers. The main aims of MiCA are industry regulation, consumer protection, prevention of market abuse and upholding the integrity of digital asset markets. The transitional period for crypto-asset service providers under MiCA ended on July 1, 2026. In June 2026, the United Kingdom’s Financial Conduct Authority published final cryptoasset rules, which are expected to take effect in October 2027.

Regulatory changes or interpretations could obligate the Trust, the Trustee or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses to the Trust.

Current and future federal or state legislation, CFTC and SEC rulemaking and other regulatory developments may impact the manner in which bitcoin is treated. In particular, although the Interpretive Release classified bitcoin as a digital commodity and not a security under U.S. federal securities laws, bitcoin may nonetheless in the future be classified by the CFTC as a “commodity interest” under the CEA or a court or a future SEC administration could conclude that bitcoin is a “security” under U.S. federal securities laws notwithstanding the Interpretive Release. The Sponsor, the Trustee and the Trust cannot be certain as to how future regulatory developments will impact the treatment of bitcoin under the law. In the face of such developments, the required registrations and compliance steps may result in extraordinary, nonrecurring expenses to the Trust. If the Sponsor decides to terminate the Trust in response to the changed regulatory circumstances, the Trust may be dissolved or liquidated at a time that is disadvantageous to Shareholders.

On October 5, 2026, the CFTC issued an advance notice of proposed rulemaking concerning Regulation Crypto Asset Transactions (“Regulation CTX”) and Regulation Crypto Asset Markets (“Regulation CAM”), seeking comment on potential rules governing certain retail crypto asset transactions and an optional federal registration framework for crypto asset trading venues. The CFTC has not proposed or adopted rules through this notice, and any subsequent rulemaking could affect the operation of digital asset trading platforms, trading activity or liquidity in bitcoin markets, which could adversely affect the price of bitcoin and the value of the Shares.

To the extent that bitcoin is deemed to fall within the definition of a security under U.S. federal securities laws, the Trust, the Trustee and the Sponsor may be subject to additional requirements under the Investment Company Act and the Sponsor or the Trustee may be required to register as an investment adviser under the Investment Advisers Act. Such additional registration may result in extraordinary, recurring and/or non-recurring expenses of the Trust, thereby materially and adversely impacting the Shares. If the Sponsor or the Trustee determines not to comply with such additional regulatory and registration requirements, the Trustee will terminate the Trust. Any such termination could result in the liquidation of the Trust’s bitcoin at a time that is disadvantageous to Shareholders.
