We have recorded Polymarket's trade tape and order-book changes since December 2025 — every gap documented. Then we simulated copying the most active wallets, with real fees and slippage. Most would have cost you money. The data knows which ones.
Products
Launch pricing. Everything ships with schema docs, provenance notes, and known gaps declared up front.
Full-depth CLOB snapshots. Crypto 15-minute windows (Jan 2026 →) and NBA/NHL/NFL game markets (Jan–Jun 2026). NDJSON, hourly files.
Not "is this wallet profitable" — what would you have earned copying it: first-entry mirroring, pessimistic slippage, 2026 taker fees, in-sample and out-of-sample months.
The living answer to "who is worth copying this month" — every wallet backtested weekly with the same rules, survivors tracked forward.

The raw material
Everything above is computed from this: the full depth of both sides of every market, on every change. Here is one real window from the archive — a BTC 15-minute market collapsing from a coin-flip to zero:
Receipts
Every number below comes from the same engine we run on our own money. Sample report, real wallet, real months:
| Window | Copied trades | Win rate | ROI (net of fees + slippage) |
|---|---|---|---|
| Jun 12 – Jul 11 | 132 | 63% | +11.3% |
| May 12 – Jun 11 (out-of-sample) | 107 | 64% | +2.5% |
Of 24 candidate wallets screened the same way, 17 were net-negative to copy — including the two biggest whales by volume. The report tells you which is which.
98% of 15-minute crypto windows flash a guaranteed-profit moment — YES + NO asks summing under $1.00. We replayed 43,297 such episodes from the archive. Median lifetime: one millisecond. Episodes lasting a full second: zero. If a bot promises you this edge, you now know what to ask them.
First datasets and reports ship to the waitlist first, with launch pricing locked in.
