2024 presidential election odds: Harris maintains narrow lead over Trump with 49 days left

Vice President Kamala Harris still holds the narrowest betting lead over former President Donald Trump as of Tuesday, just 49 days until Election Day.

Harris stood at -110 to Trump's +116 at U.K. bookmaker Betfair Exchange as of Tuesday. Biden stood at -116 at the 50-day mark in 2020, though Trump had longer odds at +132.

The spread was the largest between Trump and his Democratic challenger in 2016, when then-Secretary of State Hillary Clinton led the Trump -182 to +210. Trump won the 2016 race, though he lost the popular vote, marking the second time a betting underdog won the White House.

The action in the current race, which U.S. betting houses cannot legally take, swung back toward the vice president during the first, and likely only, debate between Harris and Trump. Punters have settled with Harris as the favorite as post-debate polls show she has a narrow lead both nationally and in swing states.
