Polymarket is reportedly in discussions with investors to raise $400 million in fresh funding at a $15 billion valuation, according to The Information, which cited two people familiar with the matter.
The raise would come just weeks after the platform received a $600 million injection from Intercontinental Exchange, the company that owns the New York Stock Exchange, bringing ICE’s total commitment in Polymarket close to $2 billion.
The new round, if it closes, could ultimately top $1 billion. The Information reported that Polymarket is looking to bring in strategic backers beyond ICE, suggesting the platform wants more than just capital, it also wants partners who can help it grow.
At $15 billion, Polymarket would still trail rival Kalshi, which was valued at around $22 billion in its most recent funding round. That gap is notable. Kalshi is already generating an estimated $1.5 billion in annual revenue and has moved aggressively to expand into mainstream financial and sports markets.
Still, Polymarket’s blockchain-based structure, which lets users globally trade yes/no contracts on real-world events using crypto, gives it a different kind of reach that its more traditionally regulated competitor can’t replicate as easily.
Prediction markets keep pulling in Wall Street money
The fundraising report lands as institutional appetite for prediction markets appears to be at a genuine peak. These platforms work by letting users buy and sell contracts tied to future outcomes, think elections, earnings reports, sports results, with prices fluctuating in real time to reflect the crowd’s collective probability estimates.
What started as a niche corner of crypto has become a serious financial product.
Monthly trading volume across prediction markets has been consistently topping $10 billion, covering everything from sports and political elections to financial results and cultural events. The sector really took off around the 2024 US presidential election, when Polymarket gained wide attention for tracking Trump’s odds more accurately than traditional polls. It hasn’t slowed down much since.
The list of established financial names moving into this space keeps getting longer. Nasdaq’s options exchange Nasdaq MRX filed to offer cash-settled binary contracts on the Nasdaq-100 index in early March, while Cboe Global Markets is also preparing a prediction market-style offering.
CME Group has partnered with sports betting company FanDuel to let traders wager on non-financial markets, and just last week, Charles Schwab and Citadel Securities said they were weighing their own entry into the space.
For context, binary contracts are financial instruments that pay out a fixed amount, or nothing, depending on whether a specific event occurs. They’re simpler than traditional options, which makes them accessible to a wider range of traders.
Regulatory clouds still overhead
The money is flowing in, but so is regulatory scrutiny. Kalshi is currently fighting the Nevada Gaming Control Board in court after a lower court temporarily blocked it from operating in the state, with the regulator arguing its contracts amount to unlicensed gambling.
Coinbase’s chief legal officer has suggested the case may eventually land before the US Supreme Court, which could produce a defining ruling on how prediction markets are treated under US law.
Polymarket has been positioning itself for that scrutiny, acquiring a licensed exchange and clearinghouse and announcing a partnership with Palantir and TWG AI to build a surveillance system designed to detect suspicious trading and manipulation in its sports prediction markets. Whether those moves will be enough to satisfy regulators long-term remains an open question.
Polymarket’s path from a 2020 crypto startup, reportedly founded out of a bathroom office, to a potential $15 billion company in roughly five years says a lot about how fast this sector has moved. Whether the current valuation holds will depend on if the institutional interest that’s driven this wave stays as strong once the novelty settles.
