Kamala Harris is the new betting favorite to become the next U.S. president following her debate against Donald Trump Tuesday evening.

Her apparent victory took her odds from +110 before the debate to -110 in the immediate aftermath to -120 by Wednesday morning. Those odds put her firmly ahead of Trump, who continues to slide from the -135 favorite to -110 to now even money at +100.

The flip from Harris to Trump also comes as Taylor Swift gave her endorsement for a candidate following the debate.

In an Instagram post, Swift said “I will be casting my vote for Kamala Harris and Tim Walz in the 2024 Presidential Election.”
