Cohven

About Cohven

Polymarket wallet tracker that shows positions rather than single trades. You add up to 30 public addresses; Cohven rebuilds each portfolio from Polygon, lists every position that three or more of them hold at once, and works out how far your own account is from that group, in shares and dollars. You place any trades yourself. A whale tracker page and a track record are free to read. The app starts with a 7-day trial on an email address, with no card, and then costs $29 to $149 a month depending on how many wallets you follow, prepaid in USDC.

How Cohven works

• The public record is the best thing here, and it is more modest than its headline. We downloaded the CSV on Nov 7, 2026: 3,307 resolved positions, 71.2% on the group's side, +$14.5 million of realised P&L. But the average entry was 69.5¢, so a 71% win rate is roughly what those prices already implied. Held to resolution, that is about 1.8¢ per share before fees. The realised P&L is 2.5% on $570 million of cost, and the 33 best positions, 1% of the list, made nearly half of it.
• Agreement did not help on cheap outcomes. The 850 positions entered under 50¢ paid 23.2¢ on average and won 15.1% of the time, a loss of about 8¢ a share if held to resolution; the realised figure for that group is close to flat, because wallets also sold before the end. Some of these may be hedges rather than bets, and the CSV does not say.
• The history also needs reading with care. The domain dates from Aug 22, 2026, while the record runs back to Jul 2024, using wallets that were picked later and that were already known to have done well. Only 386 positions were first bought after the domain existed: they won 72.5% at a 69.2¢ average entry and made 2.8% on cost, which is a fairer sample but a short one. The site does say the group is chosen by users, that past results guarantee nothing, and that wallets of very different sizes are added together. A follower also never gets the group's entry. The delay is deliberate, and rows on the site show entries of 57¢ and 75¢ with prices now at 91¢ and 98¢. The account-size calculator on the home page, which shows +11.5% in three months, is labelled a model.
• Cohven holds no keys and places no trades; a wallet connects only to sign the USDC payment. No person or company is named: the terms give the operator as “cohven” and send disputes to arbitration under general principles of international contract law. The terms list only Basic and Pro, not Plus, and the privacy policy deletes unpaid accounts 60 hours after registration, which does not fit a 7-day trial. Twelve positions we sampled at random from the CSV matched Polymarket's resolutions. We read the home, whale tracker, track record and about pages, the terms and the privacy policy; we did not sign up, so the app, the Gap view and the alerts are untested by us, and we did not recompute any wallet's P&L.
