In a stunning turn that signals prediction markets have officially arrived, the CEOs of bitter rivals Kalshi and Polymarket are jointly backing a new $35 million venture fund dedicated to the category. The firm, called 5(c) Capital, represents an unlikely alliance between platforms that have spent years battling for dominance in the exploding prediction markets space. With heavyweight backers including Andreessen Horowitz and Ribbit Capital reportedly involved, the move suggests the industry is maturing fast enough that even fierce competitors see value in growing the entire ecosystem.
The prediction markets sector just got its first category-specific venture fund, and it's backed by an alliance nobody saw coming. Kalshi CEO Tarek Mansour and Polymarket CEO Shayne Coplan are both backing 5(c) Capital, a new $35 million fund that will invest exclusively in startups supporting the burgeoning prediction markets ecosystem.
The partnership is remarkable given the companies' contentious history. Kalshi operates as a CFTC-regulated exchange offering legal event contracts to U.S. traders, while Polymarket runs a crypto-based platform that gained massive attention during the 2024 election cycle but faced regulatory scrutiny. The platforms have competed fiercely for users, media attention, and legitimacy in a space that's seen explosive growth over the past two years.
But both CEOs apparently recognize that a rising tide lifts all boats. By backing infrastructure startups rather than competing directly, they're betting the entire category needs more tools, better technology, and stronger foundations to reach its full potential. Think of it as the moment when Uber and Lyft executives might have jointly funded companies building better mapping software or payment processing for rideshare apps.
The fund's name references Section 5(c) of the Commodity Exchange Act, the regulatory framework governing event contracts in the United States. That choice signals a focus on building within existing regulatory structures rather than around them, a notable shift for an industry that's often operated in gray areas.
