Fidelity Removes Staking Caps for Ethereum and Solana ETPs to Boost Yield

Per amended filings dated August 7, the Fidelity Ethereum Fund (FETH) and Fidelity Solana Fund (FSOL) may now push staking ratios to 100% of underlying assets under normal conditions, with 85% of gross staking rewards accruing back to fund holders. For yield strategists running the numbers on vehicle selection, this compresses the spread between direct validator staking and ETP exposure in ways that change the ROI calculus.

The Structural Shift

The amended trust documents scrapped the prior cap on staked assets without imposing a new minimum. In practice, that hands the manager discretion over utilization rate — the percentage of holdings actively generating yield. FSOL has already pushed near the ceiling: as of end-June, 1,675,797 of 1,687,589 held SOL were staked, a 99.64% ratio over the trailing 30-day window. FETH disclosed 476,311 ETH held but did not break out its staked share. Fidelity indicated it modified its custody structure in August and intends to begin staking as soon as practical after the 21st, which means actual deployment ratios will lag the filing language until capital is actively rotated into validators.

Reward Economics and the 85% Line

The headline yield number deserves a second read. Investors get 85% of gross staking rewards before network-level deductions; the remaining 15% is retained by Fidelity as fees. Those rewards can be recycled into fund expenses, additional staking, redemptions, or — if Fidelity moves forward with its proposal — quarterly cash distributions to holders. But the filing explicitly states payment timing and amounts are not guaranteed, and realized yield will track network conditions and the fund's actual staking ratio. Strip out the variable components and you're looking at a vehicle where realized APY = (network staking yield × fund staking ratio × 0.85) − fund expense drag. Run that formula against direct staking on each network before sizing the position.

Liquidity Risk Vectors

Staking 100% of assets introduces withdrawal delay risk that the funds have to engineer around. The amended structure addresses this through a waterfall: unstaked reserves absorb redemption requests first; if unstaking can't clear within standard settlement, the timeline extends; if assets remain locked beyond that window, the fund can settle partially or fully in cash instead of in-kind. That's a meaningful redemption mechanism shift and worth modeling against your own exit scenarios. Fidelity also flagged additional liquidity tools under consideration — credit facilities, digital asset borrowing, sale or transfer of validator positions, and liquid staking token (LST) deployment — though as of the 21st neither product had entered a credit facility agreement, and some options require further legal, tax, and exchange-level changes.

What to Track

Three data points will determine whether this stays a yield-positive structural change or drifts into operational complexity: the realized staking ratio FETH actually publishes (FSOL's 99.64% sets a benchmark), whether quarterly cash distributions get formalized into the operating rhythm, and whether any of the additional liquidity tools — particularly LSTs — get activated. The broader backdrop is intensifying competition among staking-enabled ETPs, with SEC scrutiny continuing to evolve alongside spot ETF approvals. If you're allocating between direct staking and ETP exposure, the math now favors the ETP wrapper on operational simplicity but still demands a peg stability check on whatever distribution mechanism Fidelity ultimately settles on.
