About Winklevoss Capital

Winklevoss Capital is a family office and venture capital firm founded by Cameron and Tyler Winklevoss in New York City. The Winklevoss twins are best known for their early involvement with Facebook, which resulted in a $65 million settlement in 2008 that they partially used to purchase Bitcoin. The twins began buying Bitcoin in 2012-2013, acquiring an estimated 100,000 BTC at an average price of roughly $10 per coin, making them among the first known Bitcoin billionaires.

The Winklevoss twins also founded Gemini, a regulated cryptocurrency exchange, in 2014 and filed one of the earliest Bitcoin ETF applications with the SEC in 2013 (the Winklevoss Bitcoin Trust), which was famously rejected twice, in 2017 and 2018. Despite the ETF rejections, the twins continued accumulating Bitcoin and building institutional crypto infrastructure through Gemini. Their early and public conviction in Bitcoin, years before mainstream institutional interest, established them as pioneering figures in the cryptocurrency industry.

Winklevoss Capital manages the twins' personal Bitcoin holdings and investments in crypto and technology companies. The estimated 70,000 BTC attributed to Winklevoss Capital represents the twins' known personal holdings, though the exact figure is unaudited. Cameron and Tyler have stated publicly that they have never sold any of their original Bitcoin position, maintaining one of the longest-held and largest known individual Bitcoin positions in the world.

Methodology

Treasury balances sourced from SEC filings, press releases, and proof-of-reserves disclosures. On-chain verification tracks known wallet addresses and derives balances from the Bitcoin blockchain. Verification percentage indicates how much of the claimed treasury is confirmed by on-chain data.
