Analysis

The yield curve presents a completely flat structure across all 60 constituent markets, with every contract sharing an identical 137-day tenor to resolution. This uniformity eliminates the traditional ability to observe steepening or flattening dynamics. Within this single tenor bucket, YES probabilities cluster tightly around a 4.0% baseline, with only modest outliers: SOHT stands as a notable exception at 24.0%, while BWIT and ECRU trade at the low end at 2.0%. The weighted average probability across all markets hovers near 4.5%, suggesting the market prices the base case outcome as highly unlikely across most scenarios. The extreme concentration of volume in just three markets—AJUD, JWOO, and BROO with measurable 24-hour activity—indicates limited liquidity and engagement relative to the 60-market breadth. The flat curve structure and compressed probability distribution reveal a market that views the event resolution as highly uncertain or distant, with minimal differentiation in expectations across the constituent outcomes. The baseline 4.0% pricing on most contracts suggests the market assigns roughly equal, low probability to each individual outcome, consistent with a highly fragmented or unpredictable event space. The SOHT outlier at 24.0% indicates concentrated conviction around a single scenario, while the sparse trading activity across nearly all markets signals either nascent market formation or genuine indifference among participants. The market appears to be pricing in substantial entropy—no clear consensus has emerged about which outcome dominates, and the 137-day horizon provides ample time for information to resolve this 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 (KXLEADERMLBRUNS 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.
