These fundraising conversations remain in preliminary phases and could ultimately fail to materialize into completed transactions. Reaching these target valuations remains uncertain for both organizations.
In December, Kalshi secured $1 billion in financing at an $11 billion valuation from prominent backers including Paradigm and Sequoia Capital. The platform launched in 2018 and achieved a milestone in 2020 by becoming the first prediction market exchange to receive regulatory approval from the Commodity Futures Trading Commission in the United States.
Kalshi offers users the ability to wager on outcomes spanning athletic events, political developments, economic indicators, and entertainment topics. The platform recently surpassed the $1 billion annual revenue milestone, with certain sources suggesting the actual figure approaches $1.5 billion.
In October, Polymarket secured a $9 billion valuation when Intercontinental Exchange — the parent company of the New York Stock Exchange — committed to investing as much as $2 billion. Shayne Coplan established Polymarket in 2020.
American users cannot currently access Polymarket directly, though virtual private networks provide a workaround. The company has announced intentions to introduce a compliance-ready American version of its platform before year’s end.
Legislative Proposals Target Platform Operations
Congressional attention has intensified around both platforms recently. Representatives Blake Moore and Salud Carbajal have put forward legislation that would prohibit prediction markets from offering contracts on subjects such as armed conflicts and sporting events.
This legislative effort followed questionable betting patterns surrounding American and Israeli military operations against Iran that prompted concerns about privileged information misuse. Senator Chris Murphy suggested that individuals with White House connections may have leveraged advance intelligence about military action to place profitable wagers. Multiple Polymarket accounts allegedly generated approximately $1 million through bets placed mere hours before explosions occurred in Tehran.
Critics have also highlighted both platforms’ aggressive marketing tactics aimed at university students, including financial payments to fraternities in exchange for recruiting new members.
Suspicious Trading Claims Mount Against Polymarket
Polymarket has encountered numerous allegations of improper trading practices over recent months. A collection of cryptocurrency wallets generated over $1.2 million through wagers on a market connected to an inquiry into DeFi platform Axiom, placed shortly before blockchain investigator ZachXBT released findings about questionable trading practices associated with the project.
Another incident involved a Polymarket account that allegedly secured roughly $400,000 in profits after placing substantial wagers on the apprehension of Venezuelan President Nicolás Maduro, moments before official announcements reached the public.
According to sources with knowledge of the situation cited by the Wall Street Journal, both Kalshi and Polymarket have engaged in discussions with potential investors regarding fundraising at $20 billion valuations.
