Prediction markets let you put real money on whether something will happen — elections, sports finals, ETF approvals, AI benchmarks. Prices double as probabilities, and on Polymarket they settle in USDC the moment the outcome resolves.
Every contract is binary. You buy YES or NO shares between 1¢ and 99¢. If your side resolves true, each share pays out $1. The current price is the market's collective probability — a 64¢ YES contract means the crowd thinks there's a 64% chance.
Polymarket settles in USDC on Polygon. Kalshi runs CFTC-regulated event contracts in USD. Both expose deep order books on liquid markets and AMM-style pricing on the long tail.
Academic studies of 2024–2026 events show prediction markets beat polling, beat pundits and beat legacy bookmakers on Brier score — but only above ~$500K in open interest. Below that, you're trading against noise.
The edge: news flow gets priced in within minutes, and arbitrage between Polymarket, Kalshi and offshore books is open to anyone with a wallet and a clock.
Cross-venue arb. When Polymarket prices an outcome at 58¢ and Kalshi prices the same at 64¢, the spread is your edge minus fees.
News reaction. Set alerts on Truth Terminal, Bloomberg and Reuters; markets often lag breaking news by 30–120 seconds.
Tail hedges. Cheap "unlikely" contracts (sub-5¢) can hedge correlated portfolio risk — election outcomes, geopolitical events, regulatory rulings.
Deepest liquidity, the cultural home of crypto-native prediction trading. Order-book and AMM hybrid.
US-regulated event contracts. Cleaner compliance story, narrower market list, growing fast.
Onchain-native, ultra-fast settlement, focus on crypto and tech outcome markets.
