Analysis

The yield curve for KXPGATOUR displays a completely flat structure, with all 143 constituent markets clustered at the single 16-day tenor. Within this uniform tenor bucket, probabilities show substantial dispersion rather than a traditional curve shape. The cheapest YES probabilities concentrate at 1.0%, representing the modal outcome across roughly 80 markets, while the most expensive reach 19.0% (RMCI) and 10.0% (SSCH). This flat architecture means there is no traditional steepening or flattening dynamic to observe—the entire market is pricing outcomes for a single resolution window rather than displaying term structure across multiple time horizons. The flatness of this curve, combined with the concentration of all markets at tau=16 days, indicates the market is pricing a discrete event with a fixed resolution date rather than an uncertain timing scenario. The wide probability dispersion at this single tenor—ranging from 1% to 19%—reflects differentiated views on *which* outcome will occur within that fixed window, not *when* it will occur. The prevalence of 1% probabilities suggests the market assigns low baseline odds to most individual outcomes, with elevated probabilities reserved for a handful of favorites like RMCI (19%), SSCH (10%), and MFIT (5%). This structure implies participants view the event as binary and imminent, with disagreement centered on the specific result rather than timing uncertainty.

How to read this page

An outcome slate is a set of mutually-exclusive contracts that all settle on the same date. Their YES probabilities form a distribution over which outcome the market expects. Probabilities should roughly sum to 100% minus the venue’s overround.

Curve construction: each constituent contract is identified by its venue event_id (KXPGATOUR 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.
