Observe
Capture the same market across Bovada, sharp books, and mainstream US books.
OpenBook is rebuilding from first principles: sport-specific probabilities, timestamped prices from multiple books, and an immutable paper trail from forecast to settlement.
Every decision carries enough evidence to reproduce what the system knew, what price it saw, and why it acted.
Capture the same market across Bovada, sharp books, and mainstream US books.
Generate a probability before price selection, with model and feature versions attached.
Require edge, calibration, liquidity, and data-quality gates before a paper wager exists.
Grade the outcome, closing price, bankroll effect, and forecast quality independently.
The prototype remains available as development evidence, but it does not borrow credibility from the clean research phase.
