Across 23 games, 43 graded wallets bought before first pitch. Below: which side each cohort favoured, how much sat behind it, and — once played — how it settled.
Hits–misses over games where a cohort had a call: at least 3 of its wallets bought the moneyline before first pitch, at least $250 between them, and at least 60% of that money on one side. Everything thinner is shown on the table but not counted.
No clean-cohort buys. Not one wallet that passes the farming check and scores 65 or better bought a side on any of these games before first pitch. That is the reading, not a gap in the data — the cohort is defined before the games are, so it can come back empty, and here it did.
Watching every MLB wallet by hand is the part that doesn't scale. Set one threshold and CopyGrade emails you when any wallet it tracks — on your watchlist or not — opens a buy at or above that size on MLB markets.
Each row is one MLB game and its moneyline market on Polymarket. For every game we take the buy fills that CopyGrade's graded wallets made on that market before first pitch, split them into two cohorts — clean (graded wallets that pass CopyGrade's farming check and score 65 or higher, the Candidate band) and flagged (graded wallets that carry a farming-risk flag (watch or severe), at any score) — and show which side each cohort's money favoured, how much money that was, how many wallets, and their average fill price. A clean wallet scoring under 65 is in neither cohort. A wallet's cohort is its grade at that game's first pitch, so a later re-grade never rewrites a settled game day; a wallet not yet graded at first pitch is in neither cohort for that game. Sells, spreads, totals and props are not counted. A game day runs 09:00 UTC to 09:00 UTC the next day, so a late West-coast finish stays with its own day.
A cohort has a call only when at least 3 wallets, $250 and a 60% majority sit behind the lean; the ledger counts only those. A record from one game day is a handful of coin-flips — read the season line, not the game day, and read the guide before reading anything into it. Everything here is an observation about what a cohort bought, not a recommendation about what you should.
Wallet-level detail — who is positioned in a game and at what size — is on each game's page. Aggregates only here, by design.
