THE PROBLEM.

Prediction markets are full of mispriced events, but finding them requires deep research across multiple platforms, plus speed to act before the edge disappears.

Market-moving events happen 24/7 and you can't watch everything

FAQ.

Common questions about prediction market trading, our API, and how rekko.ai works.

What is prediction market trading?

Prediction market trading involves buying and selling contracts on the outcomes of real-world events: elections, economic data, sports, weather, and more. Platforms like Kalshi (CFTC-regulated), Polymarket (crypto-native), Robinhood, and Coinbase offer yes/no contracts priced between $0 and $1. If you buy a YES contract at $0.65 and the event happens, you receive $1.00, a 54% return. rekko.ai provides the intelligence layer that helps traders identify mispriced contracts and act before the edge disappears.

How do prediction market bots use the rekko.ai API?

Trading bots call rekko.ai's REST API to get structured signals (BUY, SELL, or NO_TRADE) with confidence scores, position sizing, and execution guidance. A typical bot flow: poll the LISTING tier for market data, request STRATEGY-tier signals for actionable trades, and use DEEP-tier arbitrage scanning to find cross-platform price gaps. The API returns machine-readable JSON, so bots can parse and execute without human intervention.

What prediction market platforms does rekko.ai support?

rekko.ai currently connects to Kalshi, Polymarket, Robinhood, and Coinbase. Cross-platform arbitrage detection runs continuously across all platforms, alerting you when the same event is priced differently on different platforms. PredictIt integration is planned for Q4 2026.

How does the prediction market API pricing work?

rekko.ai uses transparent, per-call pricing across four tiers: LISTING ($0.01/call) for raw market data, INSIGHT ($0.10/call) for AI-generated analysis and screening, STRATEGY ($2.00/call) for trading signals with position sizing, and DEEP ($5.00/call) for cross-platform arbitrage and correlation analysis. Start with 100 free LISTING calls and 10 free INSIGHT calls, or upgrade to Pro ($49/mo) for volume discounts.

Can I build a prediction market trading bot with rekko.ai?

Yes. Sign up for a free API key, then use the 27 REST + MCP endpoints to power your bot. The STRATEGY tier returns execution-ready signals (BUY/SELL/NO_TRADE) with Kelly-criterion position sizing and confidence scores. Pair that with the LISTING tier for real-time market data and the DEEP tier for arbitrage opportunities. The API is also available on RapidAPI if you prefer managed billing.

How does rekko.ai detect prediction market arbitrage?

rekko.ai continuously monitors the same events across Kalshi, Polymarket, Robinhood, and Coinbase. When the price of an equivalent contract diverges beyond a configurable threshold (default 2%), the DEEP tier flags it as an arbitrage opportunity with the exact spread, suggested position sizes, and estimated profit after fees. Webhook subscriptions can push alerts to your bot in real time.

Is prediction market trading legal?

Kalshi is regulated by the CFTC (Commodity Futures Trading Commission) and is legal for US residents. Polymarket operates on crypto rails and is available internationally. Robinhood offers event contracts through its existing brokerage platform. Regulatory status varies by jurisdiction, so check your local laws. rekko.ai provides market intelligence and educational content, not financial advice.
