TL;DR
A prediction market lets users bet on the outcome of future events (elections, sports, crypto prices) by trading shares that pay out based on results, with prices reflecting crowd-estimated probabilities.
A prediction market creates a contract for a yes/no question: “Will SOL reach $300 by June?” Shares trade between $0 and $1. If you think the probability is higher than the current share price, you buy yes shares. If the event occurs, yes shares pay $1; if not, they pay $0. The market price represents the crowd’s estimated probability. If yes shares trade at $0.35, the market believes there’s a 35% chance.
Drift Protocol’s BET feature and other platforms offer on-chain prediction markets on Solana. Markets cover crypto prices, protocol events, elections, sports, and more. Solana’s low fees make prediction markets practical — on Ethereum, the gas cost of buying a $5 position makes small bets uneconomical. Resolution is typically handled by oracles that verify the event outcome and trigger payouts.
Prediction markets offer unique opportunities: trade based on information advantage (you know something the crowd doesn’t), arbitrage between prediction markets and other instruments (if SOL call options imply different probabilities), or hedge existing positions (buy “no” shares on “SOL above $300” to hedge your SOL holdings). Markets are most liquid and efficient for popular, well-defined events.
