Best all-around choice for typical U.S. traders: broad real-money event coverage, strong liquidity, clear contract rules, mature API and trading tools, and federal exchange oversight; ranked first assuming lawful availability in the user’s state
Claude The only fully CFTC-regulated US exchange in the category — fiat deposits, brokerage-style compliance, 1099 tax reporting, and API access — with rapidly expanded coverage (economics, weather, politics, sports) after court wins cleared election and sports contracts; near-tie with Polymarket for a US practitioner who prioritizes regulatory safety over depth.
Gemini Fully CFTC-regulated US exchange offering direct USD bank integration and legal compliance for US retail and institutional event contract trading. Near-tie with Polymarket for practitioners prioritizing US legal status over global market breadth.
Grok fully CFTC-regulated fiat platform with strong US accessibility, high liquidity especially in regulated events/sports, user-friendly for beginners, reliable settlement and compliance
Where Kalshi falls short, per the models
- GPT Sports-contract access and legality still vary by state, and active-trader fees can materially erode small edges
- Claude Liquidity on most non-headline markets is thin relative to Polymarket, so large positions move prices, and fee structure (per-contract trading fees) eats edge on low-margin trades.
- Gemini Strict regulatory oversight slows market creation speed and restricts topic variety compared to decentralized competitors.
- Grok more restricted market scope and slower innovation than crypto platforms, geographic limits outside US
