Analysis

The yield curve exhibits a pronounced steepening pattern across the term structure. The 8-day tenor (SEA/TEN games on 26 AUG) trades at 41–58%, while the 12-day tenor (LAR/LAC, NE/CLE, PIT/BUF, SF/LV games on 26 AUG) compresses dramatically to 25–35%, representing the cheapest YES probabilities on the curve. From there, probabilities recover and stabilize across the 25–30 day window (SEP 09–14 games), where most markets cluster in the 35–76% range with substantially higher trading volumes. The curve's shape is distinctly non-monotonic: it dips sharply in the near-term 12-day bucket before rebounding and flattening out across the medium-term tenors. This structure reveals the market's expectation that the event family is heavily front-loaded toward the earliest resolution dates (8 days out), with a temporary repricing lower at the 12-day mark—possibly reflecting lower-profile or less-favored matchups—before normalizing across the broader September slate. The steepness and recovery pattern suggests traders view the near-term games as the primary event window, with confidence in outcomes crystallizing as the calendar extends. The elevated volumes in the 25–30 day buckets indicate these later games command more liquidity and conviction, while the 12-day trough may reflect genuine uncertainty or lower market interest in those specific matchups rather than a systematic view that outcomes become less likely.

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 (KXNFLGAME 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.
