A group of former Polymarket and Kalshi executives has launched The Clearing Company, securing a $15 million financing round led by Union Square Ventures. Coinbase Ventures and several other venture-capital firms also participated. The start-up plans to build a fully regulated, on-chain clearinghouse for prediction markets, aiming to give traders exposure to real-world event contracts while meeting U.S. compliance standards. Separately, prediction-market operator Kalshi said it has expanded its platform to the Solana blockchain, allowing users to fund accounts directly with SOL and USDC and to wager on Solana-related outcomes. The move broadens Kalshi’s product suite beyond its existing U.S. event contracts and marks its first integration with a high-speed layer-1 network. The twin announcements underscore renewed investor interest in prediction markets, which blend elements of regulated futures trading with the real-time liquidity of crypto assets. Venture capital is revisiting the sector after regulatory headwinds stalled earlier efforts, betting that on-chain clearing and faster blockchains can deliver the scale and compliance needed to attract mainstream users.
