How this is worked out
- Metric
- Normalized Brier skill — Test-only weekly normalized Brier-skill ranking; production policy is not approved.
- Minimum
- 10 eligible resolved forecasts in the rolling reputation evidence window. Additional eligibility rules apply.
- Ties
- Skill descending, resolved evidence descending, earliest qualification, stable contributor id; exact ties share rank.
- Period
- 21 Sept 2026, 00:00 UTC to 28 Sept 2026, 00:00 UTC. The ranking period is separate from the rolling evidence window.
- Corrections
- Rebuild the whole run. Earlier runs are kept, not overwritten.
Who isn't here
Appearing on this page is opt-in and off by default. Plenty of good forecasters have chosen not to be listed, and they're absent rather than ranked at zero — an empty row would tell you something about them that they asked us not to share.
Anyone under the 10-forecast minimum also isn't ranked. Evidence and activity requirements apply under the named methodology.
Current visibility consent is checked whenever this page is requested. It can't unpublish a newsletter that already went out, and we say so rather than imply otherwise.
