Prediction Market Platform XO Market Raises $6 Million in Coinbase Ventures-Led Round

Prediction markets allow traders to use contract prices to reflect the probability of an event. The sector has grown rapidly in recent years, driven by interest in politics and crypto assets. Unlike Polymarket and Kalshi, where the platforms decide which markets to list, XO Market lets individuals and companies create markets and set their own rules and fees. It hopes this user-driven model will broaden the range of markets available, though it still faces challenges involving liquidity and confidence in settlement.

XO Market announced a $6 million seed round on April 30, 2026, led by Coinbase Ventures, with participation from 20VC, Picus Capital and Venture Together. Since its mainnet beta launched in mid-November 2025, the platform has recorded more than $150 million in trading volume, attracted over 30,000 users and created more than 600 markets. XO Vaults is expected to launch within weeks, targeting an annualized yield of 8%–10%.
