Analysis

The yield curve exhibits a pronounced steepening pattern across the near-to-intermediate term, with the shortest tenor (90 days) showing the cheapest YES probability at 56.0% for H25 (the hold scenario), while the intermediate tenors (139–229 days) display elevated probabilities in the 57–69% range for H0 (no change). The curve then flattens and slightly inverts in the longer-dated contracts, with H0 probabilities declining to 53–58% at tenors beyond 300 days. The most liquid markets cluster at the 90-day tenor, where 24-hour volumes exceed $4,800, suggesting concentrated positioning around the December 26 FOMC decision. Cut probabilities (C25, C26) remain consistently low across all tenors at 1–11%, indicating minimal market conviction in rate reductions. The shape reveals a market expecting the most consequential Fed decision in the near term, with the December meeting carrying the lowest hold probability and the January meeting representing peak uncertainty about policy continuation. The subsequent flattening and slight inversion at longer tenors suggests the market anticipates either resolution of policy uncertainty by mid-year or a reversion to baseline expectations as the event horizon extends. The persistent elevation of hold probabilities across all tenors—never falling below 34%—indicates broad consensus that the Fed will maintain rates, but the term structure's dynamics imply traders view the next 90–229 days as the critical window for potential policy shifts, with conviction weakening substantially beyond mid-2025.

How to read this page

A term structure plots the implied YES probability of each constituent market against its days-to-resolution. Steepening upward = the market prices the event as becoming more likely with time. Flat = stable expectations. Inverted = a near-term catalyst raises odds early then they fade.

Curve construction: each constituent contract is identified by its venue event_id (KXFEDDECISION on kalshi). Tenor is computed from the contract’s close_time minus snapshot time, rounded to days. We do not interpolate between tenors — every plotted point is a real, traded contract. Outcome-slate pages show price-as-probability for mutually-exclusive contracts; term-structure pages show price-as-probability vs days-to-resolution for the same underlying event.

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.
