Polymarket, a leading betting platform, raised $70 million across two funding rounds. The previously undisclosed Series A secured $25 million from General Catalyst, Airbnb’s Joe Gebbia, and Polychain. The Series B raised $45 million, led by Founders Fund and featuring Ethereum co-founder Vitalik Buterin. Founders Fund partner Joey Krug praised Polymarket for its utility during breaking news. Despite US trading prohibitions, its forecasts are publicly accessible. This funding announcement coincides with the CFTC's proposed rule to ban derivatives on election bets and possibly other events.
