Gemini Exchange to Offer Cryptocurrency Block Trading

When individual trades are too large for a conventional order book to accommodate without triggering price distortions, block trading provides a solution. These transactions occur outside the public marketplace, arranged directly between buyer and seller with the assistance of a dedicated market maker. Gemini users will gain access to this functionality beginning at 9:30 AM Eastern Time on Thursday, April 12th.

The mechanics are straightforward: a trader indicates whether they're buying or selling, specifies the desired volume, sets a minimum acceptable size for execution, and proposes a price threshold. The order becomes executable once a participating market maker accepts the terms and agrees to settle the trade. This capability positions Gemini to pursue business from large institutional actors—pension funds, investment vehicles, and banking institutions—currently served by competitors like Circle Trade, a Goldman Sachs-affiliated platform that clears north of $2 billion in monthly crypto transaction volume.

The strategy mirrors established practice across equities and derivatives markets, where over-the-counter arrangements have long allowed significant position changes without roiling public markets. Recently, similar trading platforms have emerged in Asian financial hubs including Hong Kong and Sydney, responding to institutional appetite for acquiring sizable crypto holdings discreetly.

Implementation of such features may become standard across digital asset venues. Industry watchers anticipate whether Coinbase's GDAX trading interface will follow suit. Though Gemini technically opens block trading to its entire user base, practical barriers apply—participants must meet a 10 bitcoin or 100 ether minimum per order. Cameron Winklevoss noted in remarks that block orders receive simultaneous electronic distribution among market makers, with transactions kept private until their publication through market data channels ten minutes post-execution, while remaining segregated from the platform's regular order matching systems.
