Outcome probabilities

4 contracts at one resolution date

Analysis

The yield curve displays a pronounced downward slope, with YES probabilities declining sharply as tenor extends. The shortest-tenor markets at 15-16 days show the highest probabilities, ranging from 35% (ESP2) down to 17% (BEL2), while the longest-tenor markets at 21-22 days collapse to just 1-2% across nearly all constituent pairs. The cheapest YES probability resides in the 21-22 day bucket, where most markets trade at 1%, with only a handful of outliers like NZL-BEL2 (20%) and SEN2 (18%) at tau=21d. This steep inversion suggests the market is pricing in a sharp deterioration of event likelihood as time progresses. The inverted curve structure indicates the market expects the KXWC1HSPREAD event to either resolve negatively or not occur at all within the near term, with conviction strengthening substantially beyond the 20-day horizon. The concentration of meaningful probabilities in the 15-20 day window, combined with the cliff-like drop to near-zero probabilities at 21+ days, suggests either a hard deadline or resolution catalyst is anticipated around day 20. The market is essentially saying that if the event hasn't materialized by mid-tenor, it becomes increasingly unlikely to occur, with traders assigning minimal tail-risk probability to delayed resolution. The sparse trading volume at longer tenors reinforces this view, as participants show little interest in hedging far-dated scenarios.

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 (KXWC1HSPREAD 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.
