$50 billion in prediction market volume from the World Cup. I've been thinking about what that means for builders. Five years ago, prediction markets were niche. Crypto-native. Complicated. Small. Today: $50 billion in a month. From sports betting. The killer app for prediction markets wasn't politics or crypto prices. It was football. The lesson for every builder: The infrastructure you build for serious use cases gets adopted first by fun use cases. SWIFT was built for interbank transfers. Used for everything. Ethereum was built for smart contracts. Used for NFTs first. Polymarket was built for political forecasting. Reaching $50B through World Cup bets. Build the rails. The passengers find their own way in. 🏗️
