Key Takeaways
- Both Polymarket and Kalshi are pursuing fresh capital at approximately $20 billion valuations
- These figures represent nearly double their late 2024 valuations — Kalshi was at $11B and Polymarket at $9B
- Trading volume across seven prediction market platforms reached $26.7 billion in January 2026
- Each platform faces legal challenges from state authorities questioning their licensing requirements
- According to the WSJ, these discussions remain tentative and may not reach completion at proposed levels
Two dominant forces in the prediction markets industry, Polymarket and Kalshi, are reportedly in discussions with prospective investors regarding substantial new funding rounds, per a Wall Street Journal report released over the weekend. Each platform is seeking valuations in the neighborhood of $20 billion.
The report, which cited sources with knowledge of the discussions, emphasized the preliminary nature of these conversations. Journalists Kate Clark and Kevin T. Dugan indicated that negotiations remain fluid and could either fail to materialize or conclude at reduced valuations.
Kalshi launched in 2018 under the leadership of co-founders Tarek Mansour and Luana Lopes Lara. The platform secured $1 billion in financing during December 2025 at an $11 billion valuation, with participation from notable venture firms including Paradigm and Sequoia Capital.
Shayne Coplan established Polymarket in 2020. The platform attracted significant backing in October 2025 when Intercontinental Exchange, which owns the New York Stock Exchange, committed up to $2 billion in investment, establishing Polymarket’s valuation near $9 billion.
The trajectory for both platforms has been marked by rapid expansion throughout the past year. The prediction markets sector has diversified beyond political forecasting, branching into sports wagering on NFL and college football competitions, alongside markets tracking international developments.
January 2026 witnessed aggregate trading volume across prediction market platforms reaching $26.7 billion, based on analytics from Dune Analytics and user @datadashboards. This calculation encompasses seven distinct marketplace platforms.
During the closing week of 2025, weekly notional volume surpassed $5.3 billion.
Regulatory Confrontations With State Authorities
Both Polymarket and Kalshi find themselves embroiled in regulatory disputes with state-level authorities. The central controversy revolves around whether federal regulatory clearance suffices for nationwide operations, or if separate gambling permits from individual states are mandatory.
These legal proceedings remain unresolved and will likely influence the operational expansion strategies for both platforms across American markets.
Certain markets offered on both platforms have attracted scrutiny from Congressional representatives. Notable examples include prediction markets addressing potential U.S. military action against Iran and speculation regarding Iran’s supreme leader’s political future.
Rising Investor Interest Tracks Volume Expansion
Notwithstanding regulatory challenges, investor enthusiasm appears robust. The pursuit of $20 billion valuations would essentially double each company’s worth from just several months prior.
Kalshi’s December 2025 fundraising round at $11 billion represented a significant endorsement from institutional capital sources. Should the potential new financing round close, it would signal another substantial valuation increase.
Polymarket’s partnership with ICE, the NYSE’s parent organization, brought a prominent traditional finance institution into the prediction markets ecosystem.
These two organizations represent the dominant players within the prediction markets landscape. Both are currently seeking additional capital infusions as the sector continues drawing substantial trading activity and investor focus.
Neither company has publicly confirmed any completed transactions.
