Availability: The Polymarket trade tape is open to everyone in the app. Crypto whale views sit in the crypto workspace and depend on feed coverage and plan access.

## Where the sampled large-trade value went

Market share of the dollar value in the source's last-hour sample of trades above its size filter.

Status: published. Historical snapshot. Source status when captured: fresh. Within this table’s source-time freshness window; prices can change between observations.
Source observed at: 2026-09-24T00:20:00.000Z
Coverage: 13 returned trades above $10000 in the last hour; $271993 sampled notional. Polymarket Data API v2 taker-side cursor scan inspected 200 records across 1 page and reached a record before the one-hour cutoff. The filter excludes smaller trades, so this is not venue-wide flow.

| Market | Sampled notional (USD) | Share of sampled value (%) |
| --- | --- | --- |
| Houston Astros vs. Seattle Mariners | 109078 | 40.1 |
| Falcons vs. Packers: O/U 43.5 | 26500 | 9.74 |
| New York Mets vs. Texas Rangers | 26344 | 9.69 |
| Cincinnati Reds vs. Atlanta Braves | 24579 | 9.04 |
| Atlanta Dream vs. New York Liberty | 14241 | 5.24 |
| O/U 1.5 Rounds | 13620 | 5.01 |

- The denominator is the returned last-hour sample above the threshold, not all Polymarket trades or all trades in those markets.
- Rows are grouped by source condition ID when supplied; rows without one fall back to the reported title and have no exact-market link.
- A high share describes where the sampled prints occurred. It does not identify a wallet, prove one order, or predict the outcome.
- Several prints can belong to one event or one execution sequence; inspect the timestamps and the visible-print clusters below.
- Source status when captured: fresh. This snapshot is not a current quote.
