Jeff Yass is an American businessman known for helping build Susquehanna International Group, a major trading firm based in Philadelphia. He started out on the Philadelphia Stock Exchange in 1981 after getting backing from Israel Englander. Before that, he attended SUNY Binghamton and spent time as a professional gambler. In 1987, he cofounded Susquehanna with several partners. The firm later grew into a large force in options trading and market making.
His wealth comes from trading and investments, according to Forbes. Susquehanna became one of Wall Street's biggest trading firms and expanded far beyond its early exchange office. Forbes notes that the company has more than 3,000 employees worldwide and has invested in hundreds of private companies. Its most valuable holding, based on Forbes reporting, is TikTok parent ByteDance. Yass also became known for a data-driven style that fit both trading and gambling.
How Jeff Yass makes money
Yass made his name through Susquehanna International Group, the trading and technology firm he cofounded in 1987. Forbes describes it as one of Wall Street's largest and most successful trading firms. The business is especially strong in options trading and market making. That means the company helps keep markets moving by buying and selling securities. Over time, that trading engine became the main base of Yass' fortune in finance and investments.
Another big piece comes from investing. Forbes says Susquehanna has put money into hundreds of private companies around the world. The standout holding is ByteDance, the parent company of TikTok, which Forbes calls its most valuable investment. Susquehanna also built a distinct training culture. It uses poker tournaments to sharpen decision-making, and its traders have won 3 World Series of Poker bracelets. That approach matches Yass' own background as a pro gambler.

Forbes identifies his wealth sources as trading and investments, which fits both Susquehanna's market-making business and its private holdings.
