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

The platforms 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.
