Contract brief
This market will resolve to "Yes" if, on any trading day after market creation, the official daily high price published by the CME Group for the Active Month (front month) of CME Crude Oil (CL) futures is greater than $147.27 by the final trading day on or before the specified date. Otherwise, this market will resolve to "No". For CME Crude Oil (CL) futures contracts, the active month is the nearest of the contract months listed. The active month becomes a non-active month effective two business days prior to the spot month expiration. For example, if the spot month expires on a Friday the next listed contract will be considered the Active Month on the Wednesday prior to the spot month expiration. This market will resolve as soon as a high price greater than the listed value is published, or once finalized data for the final trading day of the specified time period is published and a high price greater than $147.27 has not been achieved. The resolution source for this market is the CME Group website (https://www.cmegroup.com/markets/energy/crude-oil/light-sweet-crude.quotes.html) — specifically, the daily "High" prices for the Active Month of Crude Oil (CL) futures.

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.
