Analysis

The yield curve displays a pronounced steepening pattern across the four tenor buckets, with the shortest-dated markets at 141 days showing the cheapest YES probabilities overall. At the 141-day tenor, probabilities cluster heavily in the 1-3% range for most markets, with only ALC and FIL reaching 10%, and SIN at 9%. The curve then experiences a dramatic upward shift at 275 days, where ALC and SIN jump to 35% and 40% respectively, while most other markets remain in the 1-3% range. This steepening accelerates further at 310 days (WIM tenor), where ALC holds at 30% and SIN surges to 45%, with PAU and ZVE reaching 5%. The longest tenor at 373 days shows a flattening effect, with most probabilities declining back toward 1-3%, though SIN remains elevated at 57%, suggesting a structural outlier in that market. The shape of this curve indicates the market expects the event family to remain unlikely in the near term but increasingly probable in the intermediate window between 275-310 days. The dramatic repricing between 141 and 275 days suggests a concentration of event risk in the late-summer to early-winter period, with particular conviction around SIN and ALC outcomes. The subsequent flattening at 373 days implies either diminishing tail-risk expectations or market uncertainty about whether the event resolves before or after that final tenor. The extreme concentration of trading volume at the 310-day WIM tenor (particularly in SIN, ALC, and FRI markets) reinforces that this intermediate window represents the market's focal point for when resolution is most likely to occur.

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 (KXATP 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.
