How this service works
Live Kalshi prediction markets (CFTC-regulated), with implied probability from the yes bid/ask mid, volume and open interest.
Output
A list of Kalshi prediction market records, each including the market question, current implied probability (derived from yes bid/ask midpoint), trading volume, open interest, and market status. Optionally includes Kalshi's raw original fields. Markets with no live bid/ask are excluded by default.

Technical details
Endpoint
POSThttps://mcp.gapup.io/api/v1/call/kalshi_markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, CFTC-regulated prediction market data with implied probabilities derived from actual bid/ask quotes rather than just settlement prices. Prefer this over general news or sentiment APIs when you need crowd-sourced probabilistic forecasts on political, economic, or event outcomes backed by real money. Best for agents that need structured market data rather than qualitative opinion.
Side effects
- Query string matches no markets — empty result set returned
- Kalshi API unavailable or rate-limited — upstream error propagated
- Limit exceeds maximum of 100 — validation error
- Invalid status enum value — schema validation error
- No priced markets available for query — empty list when includeUnpriced is false
