Analysis

The prediction market presents a flat yield curve with all 69 constituent markets sharing an identical 110-day tenor, eliminating the traditional term-structure analysis. Within this single tenor bucket, YES probabilities display considerable dispersion rather than a coherent curve shape. The modal probability clusters around 4.0%, representing the most common price point across approximately 40 markets. However, significant outliers exist: RDEV trades at 13.0% (the highest), BWIT at 11.0%, and MBET at 7.0%, while multiple markets trade at just 1.0% (BRIC, ECLE, ETOV, JCHO, JDUR, JJUN, KMCG, RANT, RARO, and TSOD). The cheapest YES probabilities cluster at 1.0%, suggesting these represent lower-probability outcomes within the event family. Trading volume remains minimal across the market, with only two positions showing 24-hour volume: FFRE at $241.55 and JJUN at $394.21, indicating limited price discovery. The flat tenor structure and wide probability dispersion across individual player markets suggest the market views the underlying event (MLB doubles leader outcomes) as highly fragmented rather than concentrated. The clustering around 4.0% implies a baseline expectation that most individual player outcomes carry roughly equal low probability, while the 1.0% floor likely represents genuinely unlikely scenarios. The absence of term structure prevents assessment of temporal expectations, but the uniform 110-day horizon indicates all resolution dates align. The market's current configuration reflects uncertainty distributed across many potential outcomes rather than conviction about specific timing or likelihood, with minimal liquidity suggesting these prices may not reflect deep market consensus.

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 (KXLEADERMLBDOUBLES 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.
