Key Takeaways
- Both Polymarket and Kalshi are pursuing new capital at approximately $20 billion valuations
- These figures represent nearly double their late 2024 valuations — Kalshi’s $11B and Polymarket’s $9B
- Prediction market platforms collectively processed $26.7 billion in trading volume during January 2026
- Both platforms face ongoing legal challenges from state regulators over licensing requirements
- According to WSJ, these discussions remain in early stages and may not materialize at current targets
Two dominant forces in the prediction market industry, Polymarket and Kalshi, are pursuing fresh investment capital that would value each company at approximately $20 billion, based on a weekend Wall Street Journal report.
The publication’s sources familiar with the negotiations emphasized that these discussions remain in preliminary phases and could either fall apart entirely or conclude at reduced valuations. Reporters Kate Clark and Kevin T. Dugan broke the story.
Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi secured $1 billion in December 2025 during a funding round that established an $11 billion valuation. Major venture firms Paradigm and Sequoia Capital participated as investors.
Shayne Coplan launched Polymarket in 2020. The platform received a significant boost in October 2025 when Intercontinental Exchange, which controls the New York Stock Exchange, committed up to $2 billion in investment. That deal valued Polymarket at roughly $9 billion.
The prediction market sector has experienced remarkable expansion over the past twelve months. These platforms have diversified beyond political forecasting to encompass sports wagering, including NFL and college football contests, alongside international affairs.
According to analytics from Dune Analytics and user @datadashboards, combined monthly trading activity across seven prediction market platforms reached $26.7 billion in January 2026.
The closing week of 2025 alone recorded weekly notional volume exceeding $5.3 billion.
Regulatory Challenges at the State Level
Both Polymarket and Kalshi are navigating complex legal disputes with state-level authorities. The central issue involves whether federal regulatory approval suffices for nationwide operations, or if each state’s individual gambling license is required.
These legal proceedings remain unresolved and will likely influence each platform’s expansion trajectory within United States markets.
Certain prediction markets hosted on both platforms have attracted congressional scrutiny. These include contracts speculating on potential U.S. military action against Iran and the possibility of Iran’s supreme leader being ousted.
Rising Capital Interest Mirrors Volume Growth
Regulatory obstacles haven’t dampened investor enthusiasm. The proposed $20 billion valuations would essentially double each company’s worth from mere months earlier.
Kalshi’s December 2025 fundraise at $11 billion represented a significant endorsement from institutional capital sources. Successfully completing another round at higher valuations would signal continued momentum.
Polymarket’s partnership with ICE, the NYSE parent organization, brought traditional finance credibility to the emerging sector.
These two competitors dominate the prediction market landscape. Both are actively pursuing additional capital as the industry sustains elevated trading activity and captures investor imagination.
Neither company has officially confirmed any transaction.
