Analysis

This contract predicts whether the Federal Reserve will raise interest rates by more than 25 basis points at their September 2027 meeting, currently priced at 94% probability. The market is pricing in a significant likelihood of rate increases by that date, reflecting expectations that current economic conditions will warrant tightening. The 94% probability suggests traders expect inflation or economic growth concerns to persist, or that the Fed will need to normalize rates from current levels. Near-term contracts show the market expects rates to hold steady through mid-2026 before diverging—June and July 2026 maintain rates are priced above 90%, while September 2026 drops to 68%. The September 2027 meeting is 16 months away, giving substantial time for economic data to shift expectations. Key drivers include inflation trends, labor market strength, and Fed communications between now and that meeting.

  • Current Fed funds rate level and trajectory through 2026-2027 will determine whether >25bps hikes are necessary or appropriate
  • Market expectations show high confidence in rate holds through summer 2026, but declining confidence in holds by September 2026 (68% vs 90%+), indicating a transition is priced in
  • Inflation data releases, employment reports, and Fed forward guidance over the next 16 months will be primary drivers of repricing
  • The contract's 94% probability significantly exceeds the near-term hold probabilities, suggesting market expects rate environment to shift materially between mid-2026 and September 2027
  • Historical Fed hiking cycles and current economic baseline assumptions about growth and price stability will anchor trader positioning

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.
