Winklevoss Twins: Gemini Story, Net Worth & Portfolio
The Winklevoss twins, Cameron and Tyler, who are both Olympic rowers and identical, play big roles in the crypto industry by co-founding Gemini, a top U.S. platform for trading digital currencies. Because they became Bitcoin investors early and then achieved crypto billionaire status, the twins are now well-known advocates for digital currencies. Right now, their combined net worth is estimated at $10 billion, mainly because of their Bitcoin holdings, the success of Gemini, and a variety of other investments. The piece looks at the Winklevoss twins’ background with Gemini, their significant wealth, and the expansiveness of their portfolio, illustrating how they have shaped the world of cryptocurrency.
The Gemini Story
The Winklevoss twins kicked off their crypto adventure in 2013, putting $11 million from their $65 million Facebook settlement into Bitcoin and collecting about 1% of the total supply at $8–$120 per coin. That early investment, according to Bitcoin Billionaires by Ben Mezrich, turned out to be right as Bitcoin increased in value. In 2014, they formed Gemini Trust Co., and in 2015, they started the Gemini exchange to offer a trusted and regulated service for digital currency trading. Gemini’s commitment to regulatory compliance and obtaining a license from the NYDFS gave the exchange a unique position in the market. In May 2025, Gemini handles more than 150 digital currencies, trades about $30 million each day, and is available in 60 countries.
Some of Gemini’s recent developments involve launching the Gemini Dollar (GUSD) stablecoin and an interest-earning program called Gemini Earn in 2021. The 2019 buyout of the NFT marketplace Nifty Gateway positioned Gemini to take advantage of the 2021 NFT craze, helping it strengthen its Web3 services. Gemini filed for an IPO in secrecy in March 2025, with Goldman Sachs and Citigroup as advisors, after the SEC’s probe was called off. As Bloomberg reported, the move is in line with the Trump administration’s supportive view of crypto, and companies like Kraken and Circle are also trying to go public. In January 2025, Gemini paid a $5 million settlement to the CFTC to settle claims they misled regulators, which further cleared its path going forward.
Gemini suffered some tough times in 2022 and 2024, trimming 10% of its workforce and repaying $1.1 billion to Gemini Earn customers because of Genesis Global Capital’s bankruptcy, but it continues to be central to the twins’ business. Cameron’s White House Crypto Summit address and their broader efforts in regulation show their goal to make crypto mainstream.
Winklevoss Twins’ Net Worth
As of late 2024, CoinMarketCap put the twins’ combined net worth at $10 billion, mainly thanks to their early Bitcoin buy and Gemini’s expansion. Forbes said that the twins’ net worth was $5 billion each in 2024, up from $1.4 billion each at the start of the year, mainly because Bitcoin climbed to above $104,000. At $7.28 billion in 2025, the twins’ 70,000 BTC is the largest part of their overall wealth. While a lot of early investors sold much of their Bitcoin, the twins kept most of theirs, spending just enough to get Gemini up and running, according to The Motley Fool. The twins’ combined wealth dropped to $3 billion in 2023 because of extreme volatility in the crypto market.
The twins’ holdings in Gemini and other digital assets add a lot to their wealth besides Bitcoin. The 2024 deal between the twins and New York regulators, which saw $1.8 billion paid out to Earn customers, made Gemini more trustworthy and helped their wealth. Their investments in real estate, highlighted by a $18 million LA mansion, and in new businesses add variety, but crypto is still their key holding. Their 2025 political donations highlights how wealthy they are, including Bitcoin gifts to Trump, but they paid back any extra Bitcoin as required.
Crypto and Investment Portfolio
According to BitDegree, the twins’ crypto portfolio relies most on their 70,000 BTC and is also supported by Ethereum, Filecoin, Stacks, Oasis, Tezos, and Zcash. Their 2013 stake in BitInstant, then responsible for 30% of worldwide Bitcoin transactions, was tainted by the CEO’s detainment, but afterward they invested more in Gemini. With Winklevoss Capital Management, which they founded in 2012, they’ve supported over 100 startups, mainly 23 that focus on crypto including Taxbit, Messari, and Alliance. Their 2019 BlockFi investment went bad after BlockFi filed for bankruptcy in 2022 following the failure of FTX, causing about $900 million in losses to Gemini Earn’s customers, although the twins took legal steps against Genesis to recover some costs.
They got involved in the NFT market after buying Nifty Gateway, and their subsequent Real Bedford F.C. co-ownership, realized in 2024, merged crypto with sports. Their portfolio of non-crypto deals covers fintech, AI, and consumer products, as a way to manage crypto’s volatility. Their active role in overseeing the business, thanks to their network, has created good returns for them, as exhibited by the launch of Gemini’s GUSD and credit card in 2021.

Influence and Controversies
The twins use their influence for promoting regulations and engaging with the public. Their Bitcoin ETF filing from 2017, even though it was turned down, opened the way for institutional investors to use crypto products. The twins’ 2023 X post from Cameron about Bitcoin ETF ‘floodgates’ perfectly described what happened later in 2024. However, controversies persist. They filed a lawsuit against Barry Silbert in 2023, demanding $1.1 billion, accusing him of fraudulent accounting related to Gemini Earn’s problems with Genesis. The SEC is yet to resolve its 2025 lawsuit about unregistered Earn products, but negotiations for a settlement are happening. The brothers’ 2022 spat with Genesis over $900 million in trapped funds was met with criticism for weak oversight, though settling for $1.8 billion helped.
