Key Points
- Both Polymarket and Kalshi are pursuing new capital raises at approximately $20 billion valuations
- These figures represent roughly double their late 2024 valuations — Kalshi’s $11B and Polymarket’s $9B
- Prediction market platforms recorded $26.7 billion in combined trading volume during January 2026
- State-level regulators are questioning whether both platforms require individual gambling licenses
- According to WSJ sources, negotiations remain in early stages and terms may change or deals may not materialize
Two leading prediction market platforms, Polymarket and Kalshi, are currently exploring new fundraising opportunities that would value each company at approximately $20 billion, based on a Wall Street Journal report released over the weekend.
The report, citing sources with knowledge of the discussions, emphasized that these conversations remain in preliminary phases. Journalists Kate Clark and Kevin T. Dugan cautioned that the negotiations could fail to materialize or result in lower final valuations.
Kalshi launched in 2018 under the leadership of co-founders Tarek Mansour and Luana Lopes Lara. The platform secured $1 billion in fresh capital during December 2025, achieving an $11 billion valuation. Notable participants in that funding round included Paradigm and Sequoia Capital.
Shayne Coplan established Polymarket in 2020. Last October, Intercontinental Exchange—the organization behind the New York Stock Exchange—committed to investing as much as $2 billion in the platform, establishing a valuation near $9 billion.
The past year has witnessed remarkable expansion for both organizations. The prediction market sector has diversified beyond political forecasting to encompass sports wagering, including NFL and college football betting, alongside markets for international developments.
January 2026 witnessed $26.7 billion in trading activity across prediction market platforms, based on analytics from Dune Analytics and contributor @datadashboards. This aggregate represents activity spanning seven distinct marketplaces.
During 2025’s closing week, notional trading volume surpassed $5.3 billion.
State-Level Regulatory Challenges Mount
Both Polymarket and Kalshi currently face scrutiny from state regulatory bodies. Regulators are examining whether federal authorization suffices for nationwide operations or if state-specific gambling permits are necessary.
These legal proceedings remain unresolved and will likely influence each platform’s expansion strategy within American markets.
Certain prediction markets hosted on both platforms have attracted Congressional scrutiny. These include contracts related to potential U.S. military action against Iran and the possible removal of Iran’s supreme leader.
Rising Trading Volumes Fuel Investor Interest
Regulatory headwinds haven’t dampened investor enthusiasm. The prospective $20 billion valuations would essentially double each company’s worth from just several months earlier.
Kalshi’s December 2025 fundraising at an $11 billion valuation signaled substantial institutional confidence. A successful new round at higher valuations would represent another significant milestone.
Polymarket’s partnership with ICE provided the platform with a prominent ally from traditional financial markets.
These two organizations dominate the prediction market landscape. Both are currently pursuing additional capital as the sector continues attracting substantial trading activity and investor focus.
Neither platform has officially confirmed any funding agreements.
