Cobia← cobiapicks.comCobia← cobiapicks.comSportsbooks sell opinions. We track real on-chain bets on Polymarket — whale wallets, sharp flow, live prices — score every signal with a trained model, and grade every pick in public. Losses included.
Most Polymarket whale trackers show you a firehose of large trades and leave the judgment to you. Cobia is the layer on top — proven wallets only, scored conviction, and a public record of whether the signals win.
| Raw whale trackers | Cobia | |
|---|---|---|
| Real-time large trades | Yes | Yes |
| Filters to proven-winning wallets | Rarely | Yes |
| Scores conviction into one number | No | Cobia Score |
| Verified public track record | No | 2,000+ graded, no deleted losers |
| Free daily pick | Varies | Yes |
Track the wallets that consistently win, watch where they load up before a market moves, and weight the ones with a proven record. Cobia does this automatically — it scans elite and sharp wallets on Polymarket, scores how one-sided and high-conviction the flow is, posts the pick before the line moves, then grades every one in public.
It depends on whether you want a raw feed or a graded signal. Most whale trackers show you large trades in real time and leave the judgment to you. Cobia goes further: it filters to proven-winning wallets, scores the flow into one conviction number, and — unlike a raw feed — publishes a verified record of whether those signals actually win. Wins and losses, nothing deleted.
Following whales blindly is risky — large accounts hedge across markets, so a single trade can mislead. The edge comes from following proven wallets on high-conviction, one-sided flow and sizing sensibly, not mirroring every move. Cobia filters for exactly that and shows its real hit rate so you can judge the edge yourself.
Yes. Every pick is timestamped before the game and auto-graded against the real result the moment it ends — losses shown alongside wins, nothing deleted. Over 2,000 picks have been resolved and the running record is public on the track-record page.
There's a free daily pick, a no-vig odds board, and the full public track record with no signup. The complete board — every scored pick, the Cobia Score, live smart-money alerts and player-prop leans — is on the paid tiers.
MLB, soccer, tennis, WNBA, NBA, NHL and MMA, plus player props like home runs and goals. Every signal is sourced from real Polymarket trade flow, with no bookmaker vig baked in.
