| Market | Taker side | Outcome | Notional (USD) | Price per share (USD) | Trade time (UTC) |
| --- | --- | --- | --- | --- | --- |
| Russia Elections: Yabloko Clears Duma Threshold? | buy | No | 19980 | 0.999 | 2026-09-18T07:18:34.000Z |

- The public trade endpoint returns a capped recent sample. An empty result does not prove no large trades occurred.
- A large trade does not identify a person, establish conviction, or predict the outcome of the market it was placed in.
- Price is the price paid per share of the named outcome, between 0 and 1 dollar. It is a market observation, not a probability Vultax endorses.

- Trade endpoints return capped recent samples; this is not a complete 30-minute tape. Empty results do not prove no large trades occurred.
- A large print does not identify a trader or prove directional intent. Exchange prints and Vultax detector alerts are different populations.
