Kalshi Prediction Markets is a read-only integration that surfaces exchange-grade prediction market data and portfolio views for research, monitoring, and idea generation.

Kalshi Prediction Markets is a read-only integration that surfaces exchange-grade prediction market data and portfolio views for research, monitoring, and idea generation. Core features include browsing active events and markets by category, retrieving live prices, volumes and orderbook depth, and viewing authenticated portfolio positions and P&L (requires RSA-signed API credentials). Built-in opportunity analysis flags high-certainty, high-payoff trades using thresholds (e.g., price ≥85¢ or ≤15¢ YES), expected-value calculations, minimum return filters (≥10%) and liquidity checks to ensure feasible position sizing. Use it for event-driven research, scouting asymmetric bets, monitoring exposure, and feeding signal generation into trading workflows. Setup is lightweight (pip install requests cryptography) and supports scripted commands for market discovery, search, detailed market views, and portfolio inspection.

Opportunity Analysis

The opportunities command identifies markets where:

High certainty: Price ≥85¢ YES or ≤15¢ YES (implies 85%+ confidence)
Meaningful payoff: Potential return ≥10% on capital
Sufficient liquidity: Orderbook depth supports reasonable position size

Formula: expected_value = probability * payoff - (1 - probability) * cost

A good opportunity has: EV / cost > 0.1 (10%+ expected return)

API Reference

See references/api.md for endpoint details.
