Which betting platforms let an AI agent trade for you?
Disclosure: some links on this page are affiliate or partner links. If you open an account through one, iPredictSport may earn a commission at no cost to you. The ranking below is by suitability for an automated agent, not by what we are paid, and every cell is dated 2026-09-20: fees, state availability and bot policies change monthly, so check the platform before you rely on a row.
The short version: an agent can only trade where there is an API, and only the exchanges have one. Traditional sportsbooks forbid automation, so on those the agent finds the bet and a human places it. Humans open accounts; agents trade. Never automate account creation or identity checks anywhere.
| Platform | Public API | Bots allowed | Fees | Where / age | Sign-up offer | Best for | Link |
|---|---|---|---|---|---|---|---|
| Kalshi CFTC-regulated exchange | REST + WebSocket, free with a verified account | Yes -- automation is how the API is meant to be used | Taker 7c x p x (1-p) per contract; maker a quarter of that | Most US states, 18+ | $10 credit after $100 traded; $25 referral credit after 100 trades | Your first agent. Deepest sports book of any exchange; tennis, NFL, CFB, NBA, UFC, golf all listed. | Open Kalshi (partner link) → |
| Polymarket US CFTC-regulated exchange (on-chain order book) | CLOB API; Builder Program pays developers on routed volume | Yes | Platform fee plus an optional builder fee shown before you sign | US app with identity check; wallet-based | Varies by promotion | Crypto-native builders; anyone who wants their bot to earn builder fees. | polymarket.com |
| ProphetX Peer-to-peer sports exchange (CFTC DCM + DCO approved) | Yes | Yes | Maker / taker commission | US, expanding by state | Ask | Sports-native peer-to-peer trading with an order book. | prophetx.co |
| Sporttrade Sports exchange | Yes | Yes | Commission on trades | NJ, CO, IA and others | Ask | US exchange with a sportsbook-style interface. | sporttrade.com |
| Novig Sweepstakes exchange | Limited | Ask before automating | No vig (coin model) | 40+ states, including non-sportsbook states | Ask | States where no regulated sportsbook operates. | novig.us |
| DraftKings / FanDuel / BetMGM Traditional sportsbooks | No public API | NO -- automation violates their terms | Vig, typically 4-5% on main lines | Licensed states, 21+ | Deposit matches and bonus bets, by state | The HUMAN places the pick the agent found. Never point a bot at these. | no link |
| Pinnacle / Betfair Offshore book / UK exchange | Yes | Yes | Low margin / commission | NOT available to US residents | n/a | Benchmark prices only. Listed so the comparison is honest, not as a place to sign up. | no link |
How to use this with our data
Every platform above can be driven from the same free feed: predictions.json, the OpenAPI spec for ChatGPT actions, and the MCP server for Claude, Cursor and friends. Start in paper mode. Size with fee-aware quarter-Kelly. Grade yourself on closing-line value, not win rate: our track record shows what that looks like with the n and the interval stated.
Responsible gaming. Exchanges require 18+, sportsbooks 21+, and both depend on your state. If gambling is a problem for you or someone you know, call 1-800-GAMBLER or visit ncpgambling.org. Predictions here are statistical estimates for analysis; nothing on this site is a guarantee of profit.
