Morgan Stanley's Dual-Track Amendment
The wire-house filing was the week's headline event. Morgan Stanley submitted S-1/A amendments for both its Solana Trust (CIK 0002103547) and Ethereum Trust (CIK 0002103976), with Coinbase named as custodian and staking provider across both vehicles. The exhibit trail is unusually thick — EX-10.1, EX-10.3, EX-10.12 and EX-23.1 across the two trusts — which is consistent with a product moving through operational and audit sign-off rather than sitting in early drafting.
The staking-provider designation is the detail worth flagging. Naming a staking counterparty inside the S-1/A suggests Morgan Stanley is preparing structures that can accrue staking yield, a feature the SEC has treated cautiously on prior ETH filings. Analyst commentary this week described the launch as 'getting pretty close,' though primary form approvals remain pending and no launch date has been set.
Bitwise Keeps Solana in the Queue
Bitwise submitted a Solana ETF filing during the period, keeping SOL in the active institutional product pipeline alongside Morgan Stanley, VanEck, 21Shares, Grayscale, Fidelity and Franklin. The specific product type — spot, futures or a strategy wrapper — was not disclosed in secondary summaries, and the primary SEC docket is the authoritative source. What matters at the industry level: three of the largest issuers now have visible Solana product work in flight simultaneously, and the SEC's engagement pattern on those filings over the next 60 days will shape whether SOL follows the BTC and ETH template.
SEC Watch: IBIT Options Ceiling Raised
The SEC approved higher options trading limits on the iShares Bitcoin Trust, a mechanical but meaningful market-structure change. Expanded position and exercise limits let market-makers carry larger inventories and let institutional desks size hedges without hitting cap constraints, both of which tighten spreads and deepen liquidity around the underlying ETF. The approval reads as a regulatory comfort signal on the maturity of the spot-BTC-ETF options market roughly eighteen months after listings began; it does not, on its own, set precedent for pending SOL or XRP derivatives.
Issuer Watch List: XRP Products
The XRP product cluster crossed roughly $1.5 billion in cumulative inflows across its nine-product universe, per InflowScan data. That figure is a run-rate milestone rather than a single-week event, but it validates the thesis that non-BTC/ETH single-asset ETFs can build a durable book once product structure and custody questions clear. Institutional targets in the $1.35-per-token range cited in market commentary should be read as positioning color, not a house forecast.
What to Watch Next
The Morgan Stanley amendments push the Solana and Ethereum-trust review clocks forward, and the exhibit density on both filings is the tell to track — further exhibit additions or a switch to a definitive registration statement would sharpen the launch timing question. Whether the SEC extends the IBIT options-limit posture to other spot crypto ETFs is the second beat worth watching into August.
