This is the rolling log of our automated Polymarket trading, one section per week, newest first. It replaces the individual weekly posts we used to publish (their URLs redirect here). Three notes up front, so the numbers read honestly:
- Figures were computed at each week's end from live fills only — shadow/simulated trades (force-shadowed sports under evaluation) are excluded, and trades that settled after a week's snapshot can shift its final figures slightly. The canonical, always-current ledger is /results.
- Over the full live sample, our per-trade edge is not statistically distinguishable from zero. Read individual weeks — good and bad — as variance, not signal.
- Weeks 17–25 are absent because the weekly generator wasn't running then, not because the results were unfavorable; /results covers that span.
- Weeks 31–32 (Jul 21 – Aug 3) are also absent: the archive generator was dead for those two Mondays (a regression from our own v12.289/v12.290 deploy — root-caused and fixed in v12.292, which is why Week 33 resumed). Trades from those weeks are in the ledger; only the weekly write-ups are missing. Same policy as above: we document holes, we don't backfill pretty numbers.

How the models work
The models are trained on 60,000+ historical games and predict fair win probability from game state alone — score, time, period, Elo ratings. When our fair probability exceeds the market ask by the sport's edge floor, the bot buys and holds to settlement. The full strategy and architecture are described in how our Polymarket bots work.
