00gringo00 made its first trade on 8 September at 16:47 UTC. By the time Roma kicked off at Torino on the 14th it had put $9.6 million through 81 fills, and every one of them was the same bet: a big soccer favorite, on the day it played. Dortmund. Arsenal. Sevilla. Liverpool. Brighton. Then Roma.
Five of the six won. Liverpool did not. Polymarket's own profit figure for the wallet stood at $2.49 million before the Roma game.
The Roma fill was $896,919 across five buys in fifteen minutes, 14:39 to 14:54 UTC. 1,363,355 shares at an average of 65.8 cents. That market had traded $1.8 million in total, so one buyer was close to half of it, and the price barely noticed: 66 cents going in, 64 cents an hour later. A fill that size on a sportsbook moves the number or gets refused. Here it got absorbed.
Torino 0, Roma 2. The shares paid $1,363,355. Profit $466,436.
Three hours later, the Chiefs
At 21:02 UTC the same wallet bought the Chiefs. Seven fills in six minutes, 4,133,738 shares at an average of 55.4 cents. $2,291,636. Its seventh market, and the first that was not a soccer favorite.
On the other side sat Substantial-Service. Grade S on 9,297 settled markets, #116 on our leaderboard, $7.76 million realized since October. It had bought $325,526 of the Broncos at 44 cents that morning, eighteen hours before kickoff, and another $89,819 of Broncos plus 2.5.
So the game had a wallet on a five-for-six week against a wallet with more settled markets than almost anyone on the platform, on opposite sides.
What the grade says, and what it cannot
We grade 00gringo00 C. That rests on six settled markets, which is a streak, not a record, and the grade is built to say so: thin histories are held back from the S, A and B board on purpose. Substantial-Service's S rests on 9,297.
What I cannot tell you is whether $2.29 million in six minutes is conviction or a bankroll that just doubled. From the outside they look identical. The trade history is public either way.
