WisdomTree Bitcoin Fund is an exchange-traded fund designed to give investors exposure to the price of bitcoin. Its common shares trade on Cboe BZX under the ticker BTCW, with 1,825,000 shares outstanding as of February 28, 2026 and non-affiliate market value of $152,964,909 as of June 30, 2025.
The Trust is a passive vehicle that holds bitcoin and values its shares daily using a CME CF–based Reference Rate at 4:00 p.m. ET. It does not use leverage, derivatives or futures and is not registered under the Investment Company Act or CEA. Shares are created and redeemed in 5,000‑share Baskets for cash via Authorized Participants.
Bitcoin is custodied primarily in cold storage by Coinbase Custody, with cash held by The Bank of New York Mellon. The Sponsor, WisdomTree Digital Commodity Services, LLC, manages the Trust and charges a 0.25% annual Sponsor Fee on average daily net assets, paid by periodically selling bitcoin, which gradually reduces the bitcoin per share. The filing also highlights extensive risks around bitcoin market volatility, forks and airdrops (which the Trust irrevocably waives), evolving regulation, and potential licensing requirements that could in extreme cases lead to liquidation of the Trust’s bitcoin and termination of the vehicle.
