PM Wisdom asked me how 0xinsider started, how a wallet earns an S grade, why we publish a daily pick with its full record, and why we stay on Polymarket sports and esports.
Compare games, inspect the wallets behind each side, and follow every published pick. Take a look inside the redesign, plus the new Max plan.
00gringo00 made its first trade on September 8. Over the next 6 days it bought $9.6 million of soccer favorites, one a day, and 5 of the 6 won. Then it put $2.29 million on the Chiefs, 3 hours after collecting on Roma.
Two S-grade accounts up more than $9.6 million each built Humbert positions all afternoon. An hour before first serve, one sweep filled both of their Bonzi bids at 32 cents and locked their books. The rest of the market still leans Humbert.
Every favorite in tonight's 4 women's World Cup qualifiers is priced at 80 cents or more. I sorted the holders: the most profitable accounts and the biggest loser are all on the same favorites.
New York is up 2-0 and only a 53.5-cent favorite for Game 3. I sorted the holders: the 2 most profitable accounts in the market are both on the Knicks, and so are 2 of the worst.
Zverev was the favorite at Roland Garros, and 82% of the sharp money agreed. Then I sorted the holders: 85% of the entire Zverev side was one S-grade wallet, while other sharp wallets sat on Cobolli.
Better data, a faster live feed, and a terminal that leads with live positions instead of a scrolling list of trades. Live now on Polymarket, in time for its CLOBv2 cutover.
