The prediction market became a casino. The customers became machines.
Six months, $53B, 1.4 billion trades — 78% of them in markets that live less than a day, most of them placed by 15,752 machine accounts. The full macro picture, from every fill ever placed on Polymarket.
The record year nobody described right
The common story says Polymarket peaked with the 2024 US election. The data says the opposite: the first half of 2026 alone did $53.0B — 64% of all volume in the platform’s history, seven and a half times the entire election year. 82% of every fill ever placed happened in 2026, and 89% of every market that has ever traded was created in it — about one new market every eight seconds.
