The story

Osprey Funds launched as a specialty digital asset investment manager offering low-cost alternatives to Grayscale's Bitcoin trust for accredited investors. It expanded to single-coin grantor trusts for assets like Solana. In late 2025, following the SEC's approval of spot Bitcoin ETFs, Osprey converted or relaunched OBTC as a NASDAQ-listed ETF structure, completing a pivot from private OTC trust to regulated exchange-traded product. The company remains a small (≈8-person) Fairfield, CT investment sponsor with institutional-grade custodians and fund service providers.
