What PBE said before it happened
The snapshots that count were fixed by rule before the outcome: the first published forecast, the forecast in force 24 hours before the reference time (only if one existed), and the last forecast before it. Each is shown with the Kalshi mid captured at the same moment.

|---|---|---|---|---|
| 69° to 70° | NO | 22% | — | 15% (mkt 35%) |
| 68° or below | NO | 13% | — | 8% (mkt 8%) |

| 73° to 74° | NO | 22% | — | 30% (mkt 5%) |

How it scored
Scores compare PBE and the market on the same designated snapshot — a lower Brier score or log loss is better. At the final pre-resolution checkpoint PBE's mean Brier score across 6 contracts was 0.102 against 0.081 for the market. One event is not evidence of skill in either direction.
| Checkpoint | Method | PBE | Market | n (PBE) | n (market) |
|---|---|---|---|---|---|
| First published | Brier | 0.092 | — | 6 | 0 |
| First published | Log loss | 0.301 | — | 6 | 0 |
| Final pre-resolution | Brier | 0.102 | 0.081 | 6 | 4 |
| Final pre-resolution | Log loss | 0.324 | 0.284 | 6 | 4 |
This event adds 6 resolved contracts to the model's live record (1278 resolved in total). Live calibration is published once 30 have resolved.
