Gemini, the crypto exchange founded by Cameron and Tyler Winklevoss, has built up a corporate Bitcoin treasury totaling 5,528 BTC. At current market prices, that stash is worth roughly $324M, placing Gemini among a growing cohort of crypto-native firms treating Bitcoin as a balance sheet asset rather than just a product to sell.
Approximately 80% of that Bitcoin position was financed through borrowing from the Winklevoss twins themselves. In other words, the founders are lending Bitcoin to their own company to beef up its treasury.
How the numbers stack up
Activity from Winklevoss Capital, the twins’ personal investment vehicle, appears to support this buildup. In April 2026, roughly 572 BTC worth approximately $43M was transferred to Gemini custody addresses. That suggests the treasury expansion isn’t a one-time event but an ongoing, actively managed process.
Meanwhile, Gemini Space Station, a publicly associated entity tied to the exchange, holds between 3,839 and 4,827 BTC with valuations ranging from $240M to $306M. Together, the Gemini-affiliated ecosystem’s total Bitcoin exposure could be substantially north of $500M depending on how these entities overlap.
