Fidelity’s Fidelity Solana Fund (FSOL) was already staking nearly all of its holdings when Aug. 21, 2026, 424b3 prospectus supplements formalized authority for FSOL and the Fidelity Ethereum Fund (FETH) to stake up to 100% of crypto assets, with no minimum staking requirement. As of June 30, FSOL had staked 1,675,797 of 1,687,589 SOL, a 99.64% rate with a fair value of $126.3 million against $127.079 million in net assets. FETH held 476,311 ETH and $758.609 million in net assets with no staked ether disclosed; staking is expected to begin as soon as practicable after Aug. 21 after trust and custody amendments. Each trust retains 85% of gross staking rewards after a 15% fee, allocated in priority to expenses, quarterly cash distributions to investors, redemption support and additional staking, though amounts and timing are not guaranteed. Redemptions rely first on reserves, then temporary settlement extensions and discretionary cash-in-lieu if unstaking lags; FSOL expects to recover staked SOL in about two days under normal conditions, while FETH faces variable Ethereum validator-exit and withdrawal timing. Fidelity is exploring credit facilities, crypto borrowing, validator position sales and liquid staking structures, none of which were operational in the filings. Separately, 21Shares cut the TSOL sponsor fee to zero for 12 months from July 28, 2026, and spot Solana ETFs recorded $115 million of inflows in May 2026, highlighting competition on fees as well as yield design.
