Election betting markets tighten: Harris gains ground on Trump after surprising poll shifts

Former President Donald Trump’s lead over Vice President Kamala Harris in election betting markets narrowed significantly over the weekend.

Harris even took a slight lead in one of the five major markets, as bettors reacted to positive recent polling for the Democrat, including a surprising poll showing her ahead in traditionally red Iowa.

Key Betting Market Shifts

  • Election Betting Odds Tracker: Tracking data from five major betting platforms, Trump currently holds a 54.6% chance of winning in November, compared to 45% for Harris. This marks a substantial shift from last week, when Trump had a solid lead at 63%, with Harris at 36%.
  • PredictIt: The gap has narrowed most significantly here, with Harris now leading slightly, at 55 cents per share (approximately a 55% chance of winning) compared to Trump’s 51 cents.
  • Kalshi: Following a recent federal court ruling allowing continued election betting, Kalshi’s bookmakers give Trump a modest edge of 54% to 46%.
  • Polymarket: The crypto-based betting platform, often cited by Trump and Elon Musk, still shows Trump as the favorite, with a 58% probability of victory to Harris’s 42.2%. However, this represents a notable shift from the 65-35 advantage Trump held as recently as Thursday.

Though Trump remains the favorite on most platforms, the tightening odds reflect growing uncertainty in the final days before Election Day.
