Two dominant prediction market platforms, Polymarket and Kalshi, are exploring fresh investment rounds that could value each company at approximately $20 billion, a Wall Street Journal report revealed over the weekend.
Sources with knowledge of the discussions told the WSJ that these conversations remain in preliminary stages. Reporters Kate Clark and Kevin T. Dugan emphasized that the fundraising efforts might not materialize or could conclude at reduced valuations.
Kalshi launched in 2018 under co-founders Tarek Mansour and Luana Lopes Lara. The platform secured $1 billion during December 2025 at an $11 billion valuation, with backing from major venture firms Paradigm and Sequoia Capital.
Shayne Coplan established Polymarket in 2020. Last October, the platform received a commitment for up to $2 billion from Intercontinental Exchange—the NYSE’s parent organization—establishing a valuation near $9 billion.
Both enterprises have experienced rapid expansion throughout the previous year. The prediction market sector has diversified beyond political forecasting to encompass sports wagering, including NFL and college football contests, alongside international events.
According to Dune Analytics data compiled by user @datadashboards, combined monthly trading volume across seven prediction market platforms reached $26.7 billion in January 2026.
The final week of 2025 alone recorded weekly notional volume exceeding $5.3 billion.
Legal Battles With State Regulators
Both Polymarket and Kalshi currently face challenges from state-level regulatory bodies. The central issue concerns whether federal regulatory clearance suffices for nationwide operations, or if individual state gambling licenses are required.
These legal proceedings remain unresolved and may significantly influence the platforms’ domestic expansion strategies.
Certain markets hosted on both platforms have attracted Congressional scrutiny. Notable examples include prediction contracts related to potential U.S. military action against Iran and the possible removal of Iran’s supreme leader.
Investor Appetite Grows as Volumes Climb
Regulatory challenges haven’t dampened investor enthusiasm. The proposed $20 billion valuations would essentially double each company’s worth from just months earlier.
Kalshi’s December 2025 fundraising at $11 billion represented significant institutional backing. Should the new round close, it would signal another substantial valuation increase.
Polymarket’s partnership with ICE provided the platform with a prominent ally from traditional financial markets.
These two companies dominate the prediction market landscape. Both are pursuing additional capital as the sector continues generating substantial trading activity and capturing investor interest.
Neither company has officially confirmed any fundraising agreements.
