How it works

From raw trades to tail-worthy records

No self-reported records, no cherry-picked screenshots. Every bet is reconstructed from public on-chain trade data.

1

We crawl every resolved market

The engine continuously ingests resolved Polymarket markets — soccer, NBA, esports, macro and more — with their full trade history, keyed by Polymarket's own category tags.

2

We grade every bettor's real record

A win means buying the winning side before it was a near-certainty — picking right early, not trading around it. Exits never change the record (partial or full), and an entry-price cap filters out bots buying 99¢ certainties.

3

You tail the proven ones live

Category leaderboards of the top tailers, live feeds of what they just bet, per-market consensus, and a personal feed for the bettors you choose to follow.

Features

Everything you need to tail with confidence

Built by a bettor to answer one question: whose picks are actually worth tailing?

Top-tailer leaderboards

The best bettors per league and market type — Premier League, NBA, CS2, macro… 31 categories, ranked by Tail Score, win rate or ROI, with inactive bettors automatically faded out.

Live pick feeds

See what proven bettors got on in the last 24h and spot consensus plays (3+ top tailers, same bet, within minutes) — entry signals only: exits never change a tailer's record, so your copy decision stays yours.

Market X-ray

Point it at any event and see where the top tailers stand on every sub-market — with a consensus bar and a heads-up when they disagree with the current price.

Tailer cards

Any bettor, fully unpacked: per-category record with confidence bounds, ROI, bet-type splits, current open bets and full resolved-bet history.

Your watchlist, your feed

Pin the bettors you trust — optionally only in the categories they're actually good at. My Feed shows their new picks live; My Tails tracks what resolves yesterday, today and tomorrow, win by win.

Backtest-validated rankings

The Tail Score isn't vibes. A temporal-holdout backtest verifies that bettors picked on past data keep beating their category baseline on unseen, later markets.

Methodology

Why you can trust a Tail Score

Most "top wallet" trackers rank by raw PnL — which mostly measures who got lucky on size. We rank by evidence the record will hold up on the next bet.

  • Early-call wins. A bettor gets credit for buying the side that actually won, before it was priced a near-certainty. Selling early neither helps nor hides a bad call.
  • Wilson confidence bounds. A 4-0 heater ranks below a 45-15 grinder. Small samples are shrunk toward uncertainty instead of topping the charts.
  • Difficulty-aware. Winning coin-flips at 50¢ counts for more than collecting 84¢ favorites. Entries above the price cap are excluded entirely.
  • Fees included, inactivity fades. P&L is net of ~2% fees, and bettors with no recently resolved bet drop off the boards instead of coasting on stale glory.
  • Validated out-of-sample. We split history at a cutoff date, pick leaders using only pre-cutoff data, and measure whether they keep beating the category baseline afterwards. They do — and that test ships with the product, so you can re-run it.
Tail Score
tail score = 0.40 · Wilson CI + 0.30 · capped ROI + 0.30 · difficulty
Wilson CI — the win rate we're 95% sure the bettor clears, given their sample size.
Capped ROI — profitability net of fees, capped so one moonshot can't dominate.
Difficulty — how hard the markets were at entry: 1.0 on a 50/50, lower on chalk.

FAQ

Frequently asked questions

Placing the same bet as someone whose record you trust — following their pick. The hard part isn't copying a bet, it's knowing whose record is real. That's what Polytail does: it rebuilds every bettor's actual on-chain record so you tail proof, not screenshots.

Holding the outcome that won, at the moment the market resolved. It measures picking skill independent of trade timing: a bettor who bought YES at 40¢ and held to a YES resolution scored a win, whether it was up or down along the way.

Because raw PnL and raw win rate collapse on the next stretch of bets — the top of a naive leaderboard is mostly luck and size. Our own backtest shows it: selecting by raw win rate underperforms selecting by the Wilson-adjusted Tail Score on unseen, later markets. We rank by what actually predicts the next bet.

Public Polymarket APIs (trades, positions, market metadata) — everything is on-chain activity on Polygon, reconstructed independently. No private data, no wallet connection, no permissions needed.

Live feeds hit the market data in real time when you run them. Leaderboard scores recompute when newly resolved markets are ingested (typically daily), and each page shows how old its scores are.

No. This is an independent analytics tool built on Polymarket's public data. "Polymarket" is a trademark of its owner; we just analyze the markets.
