Polymarket Facing Regulated US Competition

This is a market structure fight, not just a brand fight. Polymarket can be cheaper because it runs on crypto rails and has used zero fees to pull in liquidity, but regulated U.S. rivals like Kalshi carry the cost of licenses, compliance, surveillance, and market maker programs that let them legally serve all 50 states. Sportsbooks sit on the other end, with wider consumer reach in gambling but a much fatter built in hold and narrower contract design.1 2 3 4

• Kalshi is the clearest regulated benchmark. It spent about two years securing a CFTC license, charges retail fees that net to roughly a 1% take rate, and uses maker rebates to keep books liquid. That cost base buys nationwide U.S. access and institutional credibility.2 4
• Polymarket and Kalshi differ at the plumbing level. Kalshi runs a regulated, database based venue. Polymarket writes trades onchain and settles in USDC, which makes global distribution and low fees easier, but historically came with U.S. access limits and more onboarding friction.1 2 4
• DraftKings and FanDuel are not cheaper substitutes. Their model is to set odds as the house and keep roughly 4 to 5% of betting volume, while prediction markets match buyers and sellers more like an exchange. That is why event contracts can win on price even when the UX still lags sportsbooks.3 4

The category is heading toward a split market where regulated exchanges own U.S. distribution, crypto venues push lower cost global liquidity, and aggregators connect the two. The winners will be the platforms that become default liquidity engines for partners, not just the apps with the flashiest front end.1 4 5
