Who Are the Winklevoss Twins? From Facebook to Gemini’s Rough IPO

Cameron and Tyler Winklevoss are the founders of the Gemini exchange, the first Bitcoin billionaires, and the twins who sued Mark Zuckerberg over Facebook. They put their $65 million settlement into Bitcoin in 2013, filed the first Bitcoin ETF the same year, built the most regulated exchange in the US, bought the NFT platform Nifty Gateway, and took Gemini public in September 2025. A year later the stock is down more than 80% and they have put $100 million of their own Bitcoin back in to keep the plan alive.
