Coinbase routes US institutions into Deribit through the Prime accounts they already hold

Company figures cited by crypto.news put Deribit's July 2025 trading volume above $185 billion, with about $60 billion of open interest around the time Coinbase closed its purchase in August 2025 ^[15][16]. Twelve months at that pace comes to roughly $2.2 trillion ^[19]. That is close to the trillions in annual activity that Coinbase said in May US institutions could not reach through a regulated route ^[14]. The $2.9 billion Coinbase paid ^[15] works out to about 0.13% of one year of volume at the July rate ^[20].

The 80% figure in the announcement is Coinbase's estimate of derivatives' share of all global crypto trading ^[10]. It describes the whole derivatives market, and Deribit is one venue in it. The integration points Coinbase's existing US institutional clients at that market. The order book stays at Deribit FZE, Coinbase's affiliated foreign venue, where CFTC staff said in May that certain perpetual contracts could qualify as foreign futures under Commission Regulation 30.1 ^[8].

Eligible Prime clients can start onboarding through their account managers, and their spot trading and account relationships stay as they are ^[11]. Trading has not started. Coinbase's Oct. 7 announcement puts Prime options access in the coming weeks ^[1][5], and in May the company called options the first phase, with other derivatives products to follow ^[17]. Coinbase says US institutions will get perpetual futures as well ^[2]. It did not disclose fees, the share of Deribit flow it expects from US accounts, or a date for perpetuals.

For a desk running one of the offshore entities Coinbase says US institutions typically needed, along with separate trading infrastructure ^[12], this plays out roughly three ways. It moves its Deribit activity into a Prime relationship once options go live and closes the entity. It onboards now and keeps the entity until perpetuals reach the US route, since basis trades, one of the uses Coinbase named in May ^[18], are usually run with futures. Or eligibility, which Coinbase checks through account managers, leaves some desks outside the route altogether ^[11].

I'd expect the second. Onboarding costs a desk an account-manager conversation while the old setup still works. Closing an entity before perpetuals are dated would split a basis book across two routes. The case against is that an offshore entity carries fixed legal and operating costs a desk would gladly drop. Early options volume through Prime could pull desks across before perpetuals arrive. The view is wrong if desks start closing offshore entities in the weeks after Prime options go live.
