- YES
- YES if Adjacent's official daily value of the AI Capability Efficiency Index (ACE), the value published for 16:15 ET on an Index Calculation Day (a New York weekday, US holidays included), is strictly below 900.00 on any Index Calculation Day from Nov 9, 2026 through Nov 20, 2026 inclusive; otherwise NO. Only official daily values count: indicative 60-second values, weekend values and intraday prints don't. Source: Adjacent's published official values at https://adjacent.markets/indices/ace (methodology) and its public API (https://api.adjacent.markets/api/v1/public/indices/ace/prices?interval=1day); the question names ACE, so Adjacent is the only valid source. A correction or restatement Adjacent publishes under methodology section 7.4 before resolution counts; otherwise values stand as first published. A 0.00 value is a continuing official value (sections 6.6 and 7.7) and counts as below. After a methodology or version change, the official values as published count. A weekday with no official value (a halt or delayed publication) doesn't count. If ACE is discontinued before the end date, an official value already published that meets the condition counts; otherwise NO. If the API is down at resolution, the values on Adjacent's index page or an archived copy of them count. Resolves at 16:15 ET on Nov 20, 2026.
