Polymarket is back in the funding market with a much bigger target on price. The prediction platform is in talks to raise $400 million at a valuation of up to $15 billion, only about six months after a $9 billion valuation was reported.
Good to Know
A $15 billion target would lift Polymarket by about 66% from the $9 billion level reported in October 2025. That is a sharp climb for a platform that already moved from a $1 billion valuation in June 2025 to far higher territory in less than a year. Founders Fund led a $200 million round at that earlier $1 billion valuation, while Intercontinental Exchange, owner of the New York Stock Exchange, later backed the business as well.
Growth in event trading helps explain the jump. Prediction markets have pulled in heavy attention across sports, politics, crypto, economics, and global affairs, and Polymarket says it now handles more than $1 billion in weekly trades. The platform also returned to U.S. users in late 2025 after a break of more than three years, helped by a regulated exchange deal and CFTC clearance.
What stands out is how much of the story now sits outside politics alone. Sports event contracts helped pull fresh users into the space, while broader event trading kept the platform in constant view. On Polymarket, users can trade contracts across crypto, politics, sports, culture, weather, economics, and other live topics, giving the company a wide keyword footprint across prediction markets, sports contracts, event trading, crypto trading, and political betting discussions.
Controversy has also kept the brand in public view. Polymarket drew attention for markets tied to Iran, including questions about whether the U.S. would attack and whether a ceasefire would happen. Reports around those markets brought insider trading accusations after a small group of users reportedly won close to $1 million by backing a strike before month end. The contract later settled as a winner after a joint attack with Israel on the final day of the month.
To provide some context. Polymarket makes money by charging fees that change based on both category and probability. Rates are highest when odds sit close to an even split and lower when a result looks far more certain. Reported fee levels put crypto at 1.80%, economics at 1.50%, culture and weather at 1.25%, politics at 1%, and sports at 0.75%. Recent reports also note that fee coverage has widened across more categories, boosting platform revenue.
Investor appetite for platforms that blend event trading, real-time odds, and retail speculation is still very strong. A successful raise at $15 billion would put Polymarket even deeper into the top tier of the sector and add more pressure on rivals across sports prediction, political contracts, and regulated event markets.
