Polymarket vs. Kalshi, Polls & Traditional Sportsbooks: Why On-Chain Prediction Markets Beat Pundits
Why do Bloomberg, Wall Street desks, and macro hedge funds track Polymarket odds daily? Compare peer-to-peer 0%-fee CLOB orderbooks against 8%-vig traditional bookmakers and US-only platforms.
1. Traditional Bookmakers (5%–10% House Vig & Winner Bans) vs. Polymarket (0% Fee P2P CLOB)
Traditional sportsbooks and betting sites trade against you as the house, baking a 5%–10% house edge (overround) into the odds and banning sharp traders who win consistently. Polymarket never acts as the house—it matches buyers and sellers peer-to-peer on a transparent Polygon CLOB orderbook with 0% platform fees on limit orders.
2. Polymarket vs. Kalshi: Global Permissionless USDC Liquidity vs. US-Only Fiat Silos
While Kalshi operates as a US-regulated domestic exchange requiring US SSN verification and bank wires, Polymarket aggregates global 24/7 USDC liquidity across every timezone—delivering deeper orderbooks on global elections, macro rates, crypto milestones, and AI benchmarks.
