The story
Where the high-frequency desks trade thousands of times a day, kch123 makes fewer, much larger bets — mostly sports, and mostly sized like a professional who expects to be right.
Super Bowl LX in February 2026 made the account famous: Lookonchain reported it won all five of its game bets, about $1.8M in a single day, including the Seahawks to cover −4.5 bought at roughly a coin flip.
In May 2026 Deadspin ranked kch123 the most profitable Polymarket account of all time at about $11.8M. Its biggest single win on record came on soccer — Villarreal NOT winning on January 20, 2026.
