These negotiations remain in preliminary phases with no guarantee of completion. The targeted valuation may not materialize for either platform.
December brought Kalshi an $11 billion valuation when it secured $1 billion in investment from major backers including Paradigm and Sequoia Capital. The 2018-founded startup achieved a historic milestone as America’s inaugural regulated prediction market platform following 2020 approval from the Commodity Futures Trading Commission.
Kalshi offers wagering opportunities across athletics, political events, economic indicators, and entertainment topics. The platform recently surpassed the $1 billion annual revenue threshold, with industry insiders suggesting actual figures may approach $1.5 billion.
October saw Polymarket achieve a $9 billion valuation following Intercontinental Exchange’s commitment to invest as much as $2 billion. The NYSE parent company’s backing came five years after Shayne Coplan established Polymarket in 2020.
American users cannot currently access Polymarket directly, though VPN workarounds exist. The company has announced intentions to debut a compliant US platform version within the year.
Congressional Action Targets Prediction Markets
Increased congressional oversight now confronts both platforms. Representatives Blake Moore and Salud Carbajal have introduced bills seeking to outlaw prediction markets covering warfare and athletic competitions, among other subjects.
This legislative effort followed questionable betting patterns surrounding American and Israeli military operations against Iran that sparked insider trading worries. Senator Chris Murphy alleged that White House-connected individuals may have exploited advance intelligence about military strikes to place profitable wagers. Multiple Polymarket user accounts allegedly generated approximately $1 million through bets placed mere hours before Tehran explosions were confirmed.
Critics have additionally targeted both companies for aggressive campus recruitment tactics, including direct payments to fraternities for facilitating user registration drives.
Multiple Trading Scandals Plague Polymarket
Polymarket has encountered repeated insider trading accusations recently. Connected cryptocurrency wallets generated over $1.2 million through wagers on a market concerning DeFi platform Axiom investigations, placed shortly before blockchain investigator ZachXBT released insider trading allegations against that project.
Another incident involved a Polymarket user account that allegedly collected roughly $400,000 following a substantial wager on Venezuelan President Nicolás Maduro’s arrest, placed just prior to public announcement of the event.
According to Wall Street Journal reporting citing informed sources, both Kalshi and Polymarket have engaged in investor conversations regarding fundraising at $20 billion valuations.
