Jev builds a spread-capture system for a Polymarket trader
Given one instruction to watch the gap between Binance Bitcoin prices and Polymarket quotes, Jev connected price feeds, calculated fair UP/DOWN prices, and added liquidity and position-size rules, reportedly earning $73,542 in a month.
this Polymarket trader didn’t build a trading bot. JEV built the entire insane system for him. according to his profile: +$73,542 in one month he gave JEV one instruction: “watch Bitcoin on Binance and tell me when Polymarket is still pricing the old move”. JEV connected the price feeds. calculated what the UP and DOWN shares should cost. then added rules for liquidity, entry price and position size. the first version looked profitable but kept finding gaps that disappeared before an order could fill. so JEV rebuilt it around prices the account could actually enter. that changed everything. most 15 minute markets were ignored. but when Bitcoin moved and Polymarket stayed behind, the system acted before the gap closed. the system wasn’t trying to predict where Bitcoin would go next. it was checking whether Polymarket had caught up with where Bitcoin already was. that’s the part that gave me fomo. he didn’t hire a developer. he explained the idea to JEV and let it build the machine. according to his profile: https://polymarket.com/@dgdgt345dfgdf23?via=markus
