Macro
No qualifying macro event was retained for this report window.
Crypto
The Solana Foundation announced that Open USD was live on the network, allowing businesses to mint and burn 1:1 against dollars at no cost, with more than $1 billion committed to liquidity. The launch provides Solana-specific infrastructure context. Its event-specific market reaction is unavailable, so the evidence does not establish that it drove the options compression.

RV observation windows
The 24-hour, seven-day and 30-day RV windows are assessed independently using observed one-minute index returns, annualised on a 365-day basis. Recorded minimums: at least 99.5% coverage over 24 hours, 99.5% coverage over seven days, 99.5% coverage over 30 days, with no gap longer than 60 minutes. Returns spanning gaps are excluded, not interpolated; unavailable windows remain unreported. The exact 24-hour spot return requires prices at both endpoints.
