How to read this page

What counts as a whale order?

Here, a single order of $50,000 or more on one market. Smaller sizes have their own names: Shark from $10,000 and Dolphin from $1,000. We size by the dollars paid, not by the number of contracts, because 50,000 contracts at 2¢ is only $1,000.

Does a large order mean the buyer knows something?

No. A large order shows where money went, not who is right. It can be a hedge against another position, someone leaving a position, a market maker, or simply a mistake. Treat it as a reason to look at the market, not as a signal to follow.

Why is there no name on Kalshi orders?

Kalshi is a regulated exchange and does not publish who trades; its public feed has the size, price, side and time only. Polymarket's international platform runs on a public blockchain, so the wallet address of each order is public, and we link it to its profile there.

What does "1.5× its daily volume" mean?

We compare the dollars of the order with what that market traded in the 24 hours before. Up to the whole day it is shown as a percentage (28% of its daily volume); above that, as a multiple (1.5×, 3×, 10×). A high multiple is common in a market that has just opened or is usually quiet, so read it together with the dollar amount.

Why are some large orders left out?

Orders priced above 95¢ are not listed: they are usually money parked to earn the last few cents, or someone leaving a position that already won, not an opinion. We list the markets we track, plus Polymarket orders of $10,000 or more on other markets (mostly games), shown by name without a page of their own. Orders on the same market and side within half an hour are shown as one line, with the number of orders and the biggest one.
