## 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: 2026-09-27T00:20:00.000Z
Coverage: 39 returned trades above $10000 in the last hour; $978465 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 (%) |
| --- | --- | --- |
| Tulsa vs. Arkansas | 142023 | 14.51 |
| Oregon vs. USC | 136423 | 13.94 |
| UFC Fight Night: Brady Hiestand vs. Rinya Nakamura (Bantamweight, Main Card) | 112707 | 11.52 |
| Spread: 49ers (-7.5) | 82790 | 8.46 |
| Texas A&M vs. LSU | 73347 | 7.5 |
| Spread: 49ers (-8.5) | 51260 | 5.24 |

- 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.
