According to the source, U.S. regulators at the SEC and CFTC are moving to harmonize crypto rules, signaling that a turf war is over (source: source post on X dated Sep 30, 2025). According to the source, BlackRock’s IBIT has surpassed Deribit to become the largest venue for Bitcoin (BTC) options (source: source post on X dated Sep 30, 2025). According to the source, Swift and Visa are using blockchain to address cross-border payments (source: source post on X dated Sep 30, 2025). Trading implications: If confirmed by primary releases from the SEC, CFTC, BlackRock, Swift, and Visa, traders should monitor BTC options open interest and implied volatility across U.S.-listed ETF options versus crypto-native venues, dispersion between BTC spot and derivatives basis, and headline risk around regulatory harmonization that could shift liquidity toward regulated venues.
