Top 5 Web3 Prediction Markets to Watch in 2026 (Beyond Polymarket)

Prediction markets are no longer a niche experiment. Combined monthly global trading volume across major platforms crossed $24 billion in April 2026 , up from under $5 billion in mid-2025. That is a near 5x increase in under a year, driven by the FIFA World Cup, US midterm cycle, and a surge in crypto-native event contracts. The structural shift matters for Web3 users: prediction markets are now one of the most actively traded on-chain product categories, sitting alongside DEXs and perpetual futures in daily volume rankings.
