Kalshi and Polymarket Discuss Funding at $20 Billion Valuation

Investor interest in prediction markets continues to rise as two of the largest platforms discuss major funding plans. Reports indicate that both Kalshi and Polymarket are speaking with investors about new capital raises that could lift company valuations to about $20 billion each.

The discussions remain early, according to reporting from the Wall Street Journal. Even so, the figures highlight how quickly prediction market exchanges have grown alongside the wider sports and event contract sector.

Good to Know

• Kalshi and Polymarket are discussing funding rounds that could value each company near $20 billion.
• Both platforms have grown rapidly as users trade event contracts tied to politics, economics, and sports.
• Lawmakers and critics have questioned some prediction markets tied to geopolitical outcomes.

Conversations with investors reportedly began recently, with both companies exploring funding that would roughly double previous valuations from 2024. Market observers see strong interest from venture capital and institutional investors looking at the event contract sector.

Prediction markets allow users to trade contracts tied to future outcomes. Traders buy or sell positions based on whether an event will occur, which can include election results, economic data releases, sports outcomes, or geopolitical developments.

Kalshi and Polymarket Compete in Rapidly Growing Prediction Market Sector

Kalshi currently operates as the only fully regulated prediction market exchange in the United States. The platform runs under oversight from the Commodity Futures Trading Commission.

Founders Tarek Mansour and Luana Lopes Lara launched the company during 2018. Users on Kalshi trade event contracts tied to topics such as inflation levels, political elections, sports results, and macroeconomic indicators.

Kalshi valuation reached about $11 billion as recently as December.

Polymarket operates as the main competitor on a global level. Shayne Coplan founded the platform during 2020. Growth accelerated as cryptocurrency based trading expanded across prediction markets.

During October 2025, Polymarket reached a valuation of about $9 billion after a $2 billion investment from Intercontinental Exchange, the company that owns the New York Stock Exchange.

Both exchanges allow users to speculate on outcomes using financial style contracts rather than traditional sportsbook wagers.
