How this service works
Live Kalshi markets with yes/no prices normalised to probabilities, volume and open interest
Output
Returns a list of live Kalshi prediction market contracts, each with yes/no prices normalised to decimal probabilities (0–1), trading volume, and open interest figures. Data reflects real-time market state at time of request.
Example use cases
Election probability tracking
“What are the current Kalshi market probabilities on the next US presidential election outcome? Show me the yes/no prices normalised as probabilities and how much volume each contract is seeing.”
Fed rate decision market odds
“Check the Kalshi markets and tell me what traders think the probability is of a Federal Reserve rate cut at the next FOMC meeting — give me the implied probability and open interest.”
High-liquidity market discovery
“Scan all live Kalshi markets and show me the top 10 by open interest so I can see where the most capital is committed and what those contracts are pricing in.”
Technical details
Endpoint
GEThttps://x402render-u5vwpxpyua-uc.a.run.app/kalshi-marketsWhen to prefer
Choose this endpoint when you need live, normalised probability data from Kalshi prediction markets — particularly for event-driven decision-making, political forecasting, or macro probability tracking. Prefer this over raw exchange APIs when you want prices already normalised to probabilities rather than raw cent prices. Best when you need both volume and open interest alongside probabilities in a single call.
