Analysis

The yield curve for KXMLBGAME exhibits a notably flat structure across both tenor buckets, with the 4-day markets clustering around 41-66% YES probabilities and the 5-day markets similarly distributed between 32-62%. The 4-day tenor bucket contains the cheapest YES probabilities overall, with several markets pricing as low as 34-41% (WSH, MIN, LAA, COL), while the 5-day bucket shows marginally lower probabilities in select matchups like COL at 32% and WSH at 34%. The curve demonstrates minimal steepening between these adjacent tenors, suggesting that the market perceives little temporal risk premium or uncertainty accumulation over the single additional day. Volume concentration in the 4-day markets—particularly in TB ($143.5K), ATL ($43.4K), and LAD ($47.6K)—indicates that near-term resolution events command greater liquidity and trader attention. The flatness of this curve implies the market views the underlying MLB games as largely predetermined or informationally complete, with minimal expectation that new information will substantially shift probabilities between day 4 and day 5. The absence of a pronounced steepening pattern suggests traders are not pricing in significant uncertainty resolution or late-breaking developments that would cause probabilities to drift materially. Instead, the market appears to be pricing stable, relatively confident outcomes for these matchups, with the slight variations in YES probabilities reflecting genuine differences in team strength or matchup dynamics rather than temporal uncertainty. The consistent pricing across both buckets indicates that the market expects resolution to occur as scheduled without substantial delays or contingencies.

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 (KXMLBGAME 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.
