Kalshi, approved by the Commodity Futures Trading Commission, was last valued at $11 billion, while Polymarket was valued at $9 billion.

Prediction market platforms Kalshi and Polymarket are discussing potential fundraising rounds that could value each company at about $20 billion.

If completed at that level, the deals would roughly double their valuations from late 2025. The discussions remain early and may not lead to finalized investments, according to the Wall Street Journal.

Prediction markets allow users to trade contracts tied to real-world events, with categories including sports, politics, elections, and more. Traders buy and sell those contracts based on what they think will happen. Essentially, it allows users to monetize information on world events.

Kalshi already operates in the United States under approval from the Commodity Futures Trading Commission. Founded in 2018 by Tarek Mansour and Luana Lopes Lara, raised $1 billion at an $11 billion valuation in December last year.

The company recently reached an annualized revenue run rate of about $1.5 billion, according to the WSJ report citing people familiar with the business.

Polymarket, founded in 2020 by Shayne Coplan, was valued at $9 billion in October after Intercontinental Exchange agreed to invest up to $2 billion in the platform.

None of the platforms immediately responded to requests for comments from CoinDesk.

Both platforms are leading in the sector, as prediction markets have become the latest hype for traders.

According to a Dune dashboard, open interest on Kalshi is hovering over $400 million, while on Polymarket it’s at $360 million. The third-largest market, Opinion, is at $36 million.

Similarly, the weekly notional volume (total underlying value of all prediction contracts traded) on Polymarket was $1.9 billion last week, and on Kalshi, $1.87 billion, according to Dune data. Opinion saw weekly volume of $150 million, down from over $1.2 billion ahead of its token launch.

The sector has become so popular that companies, including Coinbase and Robinhood, have entered the prediction market. In fact, Wall Street giants Nasdaq and Cboe recently said they are considering rolling out yes-or-no “binary bets” for traders on the direction of traditional markets, similar to prediction-market betting.
