These saved Whale Tracker observations keep their source time, sample boundary, limits and downloadable rows. The live feature continues to update; a saved trade sample does not.

Whale Tracker dated evidence card

Whale Tracker

How much of the returned large-trade value was concentrated in one market?

15 returned trades above $10000 in the last hour; $279075 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.

How to use this evidence

Start with the dated card, inspect the saved table and source links, then compare it with the current feature. The Whale sample does not identify a person, one order or venue-wide trading. The feed announces saved data observations; articles receive separate editorial review.
