Overview
- The second amendments, filed June 18–19, 2026, propose spot Ethereum (MSSE) and Solana (MSOL) trusts with a 0.14% annual unitary sponsor fee and explicit staking mechanics.
- Both filings state that 95% of staking rewards would stay in the trusts for shareholders while 5% would pay custodians and staking service providers.
- Morgan Stanley names specific partners for custody and staking on the Ethereum filing, including Figment, Galaxy Blockchain Infrastructure, Coinbase Canada, BNY Mellon and Coinbase Custody.
- The Ethereum amendment discloses operational limits and risks, noting about 3.64 million ETH in the validator activation queue and an estimated 63-day wait before newly staked ETH begins earning rewards, plus slashing risks if validators fail.
- The filings remain under SEC and NYSE Arca review with no launch date, and the move follows Morgan Stanley’s April 8, 2026, launch of its Bitcoin Trust as the firm pursues a low-fee, yield-bearing ETF rollout that could pressure rivals on price and net yield.
