March Madness 2026

How predictions are made: Consensus odds from every major US sportsbook, averaged after removing the house’s profit margin. No AI model — the market IS the prediction. Every day’s picks are digitally signed before tipoff. If any prediction is changed afterward, the signature breaks.
Digital signatures (Ed25519) — the same technology behind SSH and software updates. This is not betting advice.

Verify any day's predictions yourself (requires Python):

Checks that the digital signature is valid — proving the predictions existed before tipoff and haven’t been changed.

What this proves: Predictions were signed before being published and haven’t been modified since. Timing is evidenced by the public Git commit history.
What this does not prove: Exact wall-clock timestamps, prediction quality, or that this is betting advice. It is not.
