Polymarket Predictions

The only honest test of whether the formula works. Predictions are logged before events resolve. Scoring uses the Brier score (lower is better, max possible = 0). Target: beat market consensus on >55% of resolved events.

How We Score Predictions

01

Formula runs

The polymarket_tracker sub-agent fetches live market data and runs the current formula version against each open market.

02

Prediction logged

Our probability estimate and the market consensus probability are both logged before the event resolves. No retroactive changes.

03

Brier score calculated

When the market resolves, both predictions are scored. Brier = (prediction - outcome)². Lower is better. Market Brier > our Brier = win.

Will the UK exit NATO by June 30, 2026?
Formula: 2.5% [0.5%, 8%]. Market started at 10%, now 5.1% (65.3% convergence toward our estimate). 73 days to resolution. NDAA Section 1250A and 180-day notification requirement make structural exit physically implausible at this horizon.

Will Keir Starmer cease to be UK PM by December 31, 2026?
Our 58% [40%, 73%] vs market that started at 67.5%, now 60.0%. 78.9% convergence toward our estimate in 2 days — strongest signal since TISZA resolved. 257 days to resolution. Semantics: probability of 'out by Dec 31' (not 'remain').
