How It
Worked

Real $1 bets on Polymarket

Every bet was placed as a $1 stake on Polymarket under @stupidgoal.atm — the "ATM" stands for Against The Market. Every result is publicly verifiable on-chain.

Contrarian strategy

The approach targeted mispriced player and team markets, betting against the crowd when odds overreacted to recent results. Positions were entered using limit orders to capture favorable prices rather than taking available odds.

Why we stopped

Polymarket introduced trading fees, making the strategy significantly less profitable for anyone following along. The full record of 900+ bets remains public on Polymarket for anyone to audit.
