Grayscale Bitcoin Mini Trust ETF is a Delaware statutory trust formed to hold Bitcoin and provide exchange-traded exposure to its price. Shares trade on NYSE Arca under the ticker BTC and are issued in 10,000‑share baskets to authorized participants in exchange for Bitcoin via cash orders.
As of December 31, 2025, the Trust held about 0.24% of all Bitcoin in circulation, with each share representing approximately 0.0004 Bitcoin. Aggregate market value of shares held by non‑affiliates was $4,746,331,139 as of June 30, 2025, and 113,779,963 shares were outstanding on February 20, 2026.
The Trust’s objective is for share value to reflect the Bitcoin it holds, determined by a composite Index Price, less expenses and liabilities. From July 31, 2024 to December 31, 2025, observed premiums and discounts to NAV per share were generally small, with a 1.74% maximum premium and 0.51% maximum discount.
Major risk themes include extreme Bitcoin price volatility, evolving digital asset regulation, reliance on third‑party service providers and custodians, potential forks or protocol changes, and the possibility that shares trade at persistent premiums or discounts to NAV, affecting investors’ realized returns.
Grayscale Bitcoin Mini Trust ETF reports key structural and tax updates. The sponsor has amended Participant Agreements with Jane Street Capital and Virtu Americas so they can handle in‑kind creations and redemptions, alongside cash orders, using Bitcoin directly rather than only cash.
The filing notes SEC approval allowing crypto-based products on NYSE Arca, including this Trust, to use in‑kind transactions with Authorized Participants or their designees. The Trust expects to rely on these in‑kind processes under newly approved NYSE Arca generic listing standards, which are intended to keep it aligned with similar commodity ETPs.
Extensive disclosure explains how baskets of 10,000 Shares are created and redeemed, the role of Liquidity Providers and cash accounts, and how failed trades are handled. The Trust also replaces and expands its U.S. federal income tax discussion, emphasizing uncertainty around digital-asset tax treatment, the goal of maintaining grantor trust status, and the potential consequences if it were instead treated as a partnership or corporation.

Under this Anchorage Digital Custodian Agreement, Anchorage Digital will provide custody and safekeeping services for a portion of the Trust’s Bitcoin holdings.
Coinbase Trust Company, LLC remains the Trust’s primary custodian, and the Sponsor will decide, in its sole discretion, how much Bitcoin is held at each custodian.

The agreement addresses how Anchorage Digital may respond to forks of the Bitcoin blockchain, including temporary suspensions and decisions on which branch to support. It also includes indemnification obligations by the Trust in certain circumstances and requires Anchorage Digital to maintain insurance coverage. Related custody agreements are filed as exhibits.
