Trump's odds of winning the election temporarily dropped on Polymarket after a top holder of "yes" shares in Trump's victory, known as Theo4, placed bets against Trump and on Harris. Theo4, who holds 12 million Trump "yes" shares, briefly bought "no" shares for Trump and "yes" shares for Harris before returning to buying Trump shares. This caused Trump's odds to slip from 65% to as low as 59%, though they later rebounded. Source: Coindesk
