Every figure here describes what TailMyPicks scored — positions held to resolution in markets that cleared the thresholds below. It is not a Polymarket account balance, and open positions are not counted anywhere on this site.
Who was on this market
All 36 wallets that hold a qualified pick on this market, biggest position first. Ordered by position size rather than by score, because this is a post-mortem of one market — a strong wallet’s small pick does not belong above a large committed one. Each wallet’s record in Tennis is on its own row, so one correct call here is not mistaken for a track record.

Entry is the average price this wallet paid on the side it backed, so being right at 20c is distinguishable from being right at 95c. Position is what it was left holding in shares, with what it spent underneath. Result opens that one pick on a page of its own, which is the link to send somebody. P/L held is what that position would have been worth held to resolution — not cash the wallet withdrew, because selling early is still a correct forecast. The seven columns on the right describe the wallet’s whole record in Tennis and say nothing about this market.
The rest of this event
Polymarket sells these questions together. 2 in all. TailMyPicks has no name for an event — the venue publishes an identifier and no title — so they are listed by their own questions.

Not every trade counts. A Pick has to clear four thresholds to be scored.
TailMyPicks scores a wallet on what it can actually be judged on: positions held to resolution, in markets with enough volume to be real, at prices where being right was not already priced in.
- The market traded at least $500.
- The entry price was between 0.00 and 0.80 — a near-certainty is not a call.
- The position was at least $10 — dust is not a position.
- The market has resolved, so there is a right answer to grade against.
Thresholds behind these numbers: set by an operator decision, not measured.
