Sources indicate these fundraising conversations remain preliminary, and neither platform has secured commitments at these target valuations.

In December, Kalshi completed a significant funding round at an $11 billion valuation, securing $1 billion from prominent investors such as Paradigm and Sequoia Capital. Established in 2018, the platform achieved a historic milestone by becoming America’s inaugural regulated prediction market exchange following CFTC authorization in 2020.

Kalshi enables participants to wager on diverse outcomes spanning sports events, political developments, economic indicators, and cultural phenomena. The platform recently surpassed the $1 billion annual revenue threshold, with industry insiders suggesting actual figures may approach $1.5 billion.

Polymarket secured its $9 billion valuation in October when Intercontinental Exchange—the parent organization of the New York Stock Exchange—committed to investing as much as $2 billion. The platform launched in 2020 under founder Shayne Coplan’s leadership.

Currently, Polymarket prohibits direct access to American users, though VPN workarounds exist. The company has announced intentions to introduce a compliant US platform iteration this year.

Congressional Efforts to Restrict Prediction Markets

Regulatory challenges are mounting for both platforms as Congressional representatives intensify oversight. Representatives Blake Moore and Salud Carbajal have co-sponsored legislation aiming to prohibit prediction markets covering military conflicts and sporting events.

This legislative initiative emerged following questionable betting patterns surrounding US and Israeli military operations against Iran that suggested possible insider knowledge. Senator Chris Murphy voiced concerns that individuals with White House connections potentially exploited classified information about the strikes for financial gain. Evidence suggests multiple Polymarket users collectively earned approximately $1 million through wagers placed mere hours before explosions occurred in Tehran.

Additionally, both companies face criticism for marketing tactics targeting university students, including reported payments to fraternity organizations for recruiting members.

Allegations of Insider Trading Continue Plaguing Polymarket

Polymarket has confronted numerous insider trading accusations throughout recent months. Connected cryptocurrency wallets generated over $1.2 million through strategic betting on a market linked to an Axiom DeFi platform investigation, placing these bets shortly before blockchain analyst ZachXBT released findings about insider trading connected to that project.

Another controversy involved a Polymarket user who allegedly secured roughly $400,000 in profits after making substantial wagers on Venezuelan President Nicolás Maduro’s potential capture, timing the bet just ahead of the story breaking publicly.

The Wall Street Journal reports that both Kalshi and Polymarket have engaged in preliminary discussions with potential investors regarding fundraising at $20 billion valuations, according to individuals with knowledge of these negotiations.
