Whale tracker: large trades in context

What counts as a whale here

There is no agreed definition, so Vultax uses a stated one: the Polymarket table filters to trades above a published dollar threshold, and prints that threshold in the coverage line above the table along with the oldest trade in the sample. If the threshold changes, the line changes with it. A tool that says 'whale' without saying how big is describing a feeling.

The crypto tables use a separate threshold and a separate lookback, both printed with them, because a large trade on a spot exchange and a large trade on a prediction market are not the same size of thing.

What a large trade does and does not tell you

It tells you that the source reported a fill of a stated size, side, outcome, price and time. Those fields are useful observations, provided you check the source time and the scope of the feed.

It does not tell you who traded, why, or whether they were right. A large buy can be a hedge against a position somewhere else, a market maker balancing inventory, or a mistake. Public aliases and wallet addresses do not establish identity, and Vultax does not attempt to attach a name to one. Read the print, then look for a second reason.

Sampling, and why an empty table is not silence

Vultax follows the public thresholded taker-side feed back to the one-hour boundary with bounded cursor pages. The coverage line reports how far that scan reached. It shows at most eight individual prints and separately sums the returned last-hour value by market. Smaller trades are outside this view, and a large market share is not a share of all venue activity.

Crypto whale figures are collected on their own schedule and can go stale independently of the prediction-market ones. Each table carries its own status and reason, and marks itself stale rather than quietly ageing.

How to read a single print

Start with the named outcome and the source-reported taker side. A buy and a sell of that outcome mean different things; the notional alone cannot tell you which happened. The row preserves both fields rather than turning every large print into a bullish signal.

Then read the price. A fill at eighty-five cents has a different payout and downside from one at fifteen cents. Size and price give context, but they cannot reveal a trader's conviction, whole position or reason for trading.

Then read the clock. Several displayed prints in the same second and market may be related, so the page groups those visible prints without guessing the order or wallet behind them. Timing can suggest a question to investigate; it does not establish cause.

Prediction-market whales and crypto whales are not the same animal

Prediction-market shares have event-specific settlement terms. A holder who keeps a losing side through resolution can lose the price paid for those shares, while a trader can also close earlier. The print alone cannot show the position held through resolution. Spot exchange prints have different instruments and risks, so their sizes need separate context.

It also makes the population different. Polymarket flow is public at the wallet level because positions settle on a public chain, so the same trade can be followed to a trader and, over time, to a record. Crypto exchange prints are venue-side: you see that somebody bought, not who, and an exchange print cannot be matched to an on-chain wallet.

That is why the two are on one page but in separate tables with separate thresholds and separate coverage notes. Merging them into a single feed would produce a stream where the same word meant two different things.
