Polymarket Seeks $400M At $15B Valuation As Prediction Markets Draw Wall Street Cash

Polymarket is in talks to raise $400 million in fresh funding at a valuation near $15 billion, people familiar with the talks said.

Polymarket Funding Round

The prediction market platform is courting investors for capital that could lift the round to $1 billion in total, The Information reported Sunday. Reuters and Investing.com confirmed the details.

The new round would mark a sharp jump from the $9 billion valuation Polymarket carried earlier this year.

It also follows a $600 million check from Intercontinental Exchange, the parent of the New York Stock Exchange, in late March. That deal was part of a broader commitment of up to $2 billion from ICE.

Polymarket is now looking to bring in strategic backers beyond ICE, sources told the outlet. The company declined to comment.

Prediction Market Boom

The push lands as prediction markets record over $10 billion in monthly trading volume, according to Token Terminal data. Rival Kalshi was marked at $22 billion in its last round, still well ahead of Polymarket.

Wall Street is circling the sector. Nasdaq MRX filed to offer binary-style contracts on the Nasdaq-100, while Cboe and CME Group are building their own event products. Charles Schwab and Citadel Securities are also weighing entries.

Polymarket itself has moved fast this year. The firm acquired QCEX for $112 million to secure CFTC clearance, published a 2026 insider trading rulebook in February, and picked up DeFi infrastructure startup Brahma in March. Daily volumes hit roughly $478 million that same month, per Investing.com figures.
