$10,253 on Celtic - Glasgow Rangers — Premiership

Tracked on tail.bet, Celtic generated $165,782 in wagered volume across five bets, with all four settled outcomes resulting in wins. Despite the perfect conversion rate, the position closed at minus $30,820 and a negative 18.6% ROI, driven partly by odds pricing on the largest captured bet—a $60,000 single on Celtic to beat Hibernian that returned $73,200.
