Investing.com-- Polymarket is in talks with investors to raise $400 million in funding, valuing the prediction market operator at $15 billion including new money, The Information reported on Sunday, citing two people familiar with the talks.

The funding would add to the $600 million invested by the Intercontinental Exchange Inc (NYSE:ICE) in late-March, with the New York Stock Exchange parent having earlier pledged to invest up to $2 billion in Polymarket.

The prediction market operator is looking to add more strategic investors beyond Intercontinental Exchange to the funding round, which could total $1 billion, the Information report said.

The wave of new funding comes amid the growing popularity of online prediction markets such as Polymarket and rival Kalshi. A report in March put Kalshi's valuation at $22 billion, roughly twice a late-2025 valuation of $11 billion.

The two allow users worldwide to wager on a host of outcomes, across sports, entertainment, politics, and more recently, even the U.S.-Israel war on Iran. Prediction markets have become wildly popular among U.S. consumers, with Polymarket seeing daily volumes of about $478 million as of March 2026.

But this increasing popularity has also attracted legal scrutiny in the U.S., with several states accusing online prediction markets of engaging in illegal gambling operations. Concerns over prediction markets being pathways for insider trading have also emerged in recent months.
