How this service works
Live probability: Will the Fed hike rates at its next FOMC meeting? — Stable evergreen URL for a recurring question: Will the Fed hike rates at its next FOMC meeting? Auto-resolves to the current market instance and rolls forward on resolution, so the answer is always about the next occurrence. Response adds current_slug and rolls_to_next_at to the standard probability shape.
Output
Returns a JSON object with an aggregated probability (0–1) of a Fed rate hike at the next FOMC meeting, per-venue breakdown from Kalshi and Polymarket (each with implied probability, 24h volume, and liquidity score), cross-venue divergence, 1-hour probability change, current market slug, resolution date, when the evergreen URL will roll forward to the next meeting, and a plain-language summary of resolution criteria.
Example use cases
Real-time Fed hike odds for macro dashboard
“Pull the latest probability that the Fed hikes at the next FOMC meeting and show me what Kalshi and Polymarket are each implying, plus how much the number has shifted in the last hour.”
Briefing before a portfolio rebalance
“Before I rebalance my bond positions, what does the prediction market say about a Fed rate hike at the next meeting? Give me the aggregate probability and the resolution date.”
Alert bot for significant Fed hike probability moves
“Check the Fed next-meeting hike probability right now and tell me if it has moved more than 5 percentage points in the last hour — I want to know if something is moving the market.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/fed-next-meeting-hikeWhen to prefer
Choose this endpoint when you need a single, always-current probability estimate for the next Fed rate hike without having to look up or manage the specific market slug for each FOMC cycle. It is ideal for macro dashboards, automated briefing agents, and alert systems that need the Fed hike probability on demand without tracking individual market lifecycles. Prefer this over direct Kalshi or Polymarket APIs when you want cross-venue aggregation and divergence in one call.
Side effects
- No active FOMC market available — returns stale or null probability if between resolution and next market creation
- Payment failure — $0.02 USDC x402 payment not accepted, returns 402 Payment Required
- Venue data unavailable — one or both of Kalshi/Polymarket data feeds down, resulting in partial per_venue array
- Rate limiting — too many requests in a short window returns 429
