Prediction market platforms Kalshi and Polymarket are reportedly exploring new fundraising rounds that could value the companies at around $20 billion each, roughly double their most recent valuations.

Both platforms have held preliminary discussions with potential investors about raising fresh capital at the elevated valuation, the Wall Street Journal reported on Friday, citing people familiar with the matter. The report noted that the negotiations remain at an early stage and may not result in deals or secure the targeted valuation.

Kalshi currently operates in the United States and offers markets allowing users to wager on outcomes tied to sports, politics, the economy and cultural events. The company was last valued at about $11 billion in December when it raised $1 billion from investors including Paradigm and Sequoia Capital.

Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi received approval from the US Commodity Futures Trading Commission in 2020 to operate as a regulated exchange for event-based markets. The platform has since expanded rapidly and recently surpassed a $1 billion revenue run rate, with some estimates placing the figure closer to $1.5 billion.

Polymarket plans US launch later this year

Polymarket, launched in 2020 by Shayne Coplan, remains inaccessible to US users without a virtual private network but plans to introduce a regulated domestic version of its platform later this year. The company was valued at roughly $9 billion in October after Intercontinental Exchange, the owner of the New York Stock Exchange, agreed to invest up to $2 billion.

Both platforms have drawn attention from lawmakers and regulators. As Cointelegraph reported, US Democratic lawmakers are drafting legislation to regulate prediction markets after suspiciously timed bets on the timing of US and Israeli strikes on Iran raised insider-trading concerns.

Senator Chris Murphy alleged that individuals close to the White House may have used advance knowledge of the attack to place bets, noting that several Polymarket accounts reportedly made about $1 million by wagering just hours before explosions were reported in Tehran.

Polymarket faces insider trading suspicions

Polymarket has faced multiple insider trading allegations after several traders placed unusually well-timed bets on major events. A small group of crypto wallets recently made more than $1.2 million betting on a market tied to an onchain investigation into DeFi platform Axiom shortly before blockchain investigator ZachXBT published claims about insider trading linked to the project.

In a separate incident last month, another Polymarket account reportedly earned about $400,000 after placing a large wager on the capture of Venezuelan President Nicolás Maduro shortly before the news became public, further raising questions about whether some traders had advance information.
