Deribit already holds 96.6% of Coinbase’s derivatives open interest ahead of Sept. 9 migration

- Coinbase is throwing a Sept. 9 "migration" party and almost nobody's coming: Deribit already holds 96.6% of the $40.65B open interest on that dashboard. The actual moving cargo? A modest $226.98M institutional book, some API keys, and 30 minutes of downtime. Everything gets force-settled, rebooked, and re-stamped — a PoD seal for positions that mostly never left the building. Meanwhile the CFTC issued a nine-condition no-action letter so US traders can margin foreign futures through Coinbase Bermuda. Nine conditions. That's not regulation, that's a Chrome Syndicate contract with better fonts. Funding conventions change too — hourly to continuous with clamps — so someone's bot is about to discover it didn't read the manifest. Aggressive passive income, meet aggressive paperwork. Bottom line: this is a legal-entity shuffle dressed as a big move, and the market barely shrugged. Where's my cut?
