Analysis
This contract measures whether the Federal Reserve will maintain interest rates unchanged at their September 2027 meeting, which markets currently assess at 84% probability based on trading activity. The high probability reflects expectations that inflation will remain near target and economic conditions will stabilize by late 2027, reducing pressure for rate changes. The primary drivers moving this probability would be shifts in inflation data, labor market conditions, and Fed communications over the next 15 months. The next major catalyst is the Fed's September 2026 meeting in roughly three months, which will signal the Committee's near-term policy stance and inform expectations for 2027. Subsequent inflation reports, employment data, and any Fed guidance changes will incrementally adjust market expectations for the September 2027 outcome as traders refine their economic forecasts across the forecast horizon.
- ›Current market pricing shows 84% probability of no rate change in September 2027, with 15% probability assigned to a 25bps hike and minimal probability to cuts
- ›The nearest-term contract (July 2026) shows 84% probability of no change, suggesting traders expect rate stability to persist through the intermediate term
- ›September 2026 contracts price in 60% probability of no change and 3% probability of a 25bps cut, indicating some expectation of easing before 2027
- ›Trading volume is concentrated in the July 2026 near-term contract ($52,675 24h volume), with volume declining significantly for later-dated contracts
- ›The outcome depends critically on inflation trajectory, labor market resilience, and Fed communication between now and September 2027—approximately 15 months of economic data and policy guidance remain to be released

Fed Rate Hike Odds Surge: September Hike vs. Hold is a Toss-Up

How we compute these odds
SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.
For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.
Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
