Cobia tracks where the smart money loads up on Polymarket, posts the pick before the line moves, and grades every one in public. Here's the running PortlandFire record — losses included.
Every pick is timestamped when called and auto-graded when the game resolves — nothing deleted. These are often favorites priced fairly, so the real edge is closing-line value, not flat-stake ROI. Past results don't guarantee future returns.
