Harris cements place as bettor's top Dem., Trump's odds lengthen after Biden drops out

President Joe Biden dropped out of the presidential race Sunday, shaking up the political campaign and the betting markets.

Vice President Kamala Harris solidified her position as the leading Democratic candidate in the betting market, completing a charge that began after Biden was diagnosed with COVID Wednesday.

Biden endorsed Harris in a separate social media post, followed by the Clintons who remain power players in the party.

Former President Donald Trump remains the betting favorite in the Presidential race, which bookmakers can't legally take action on in the U.S., though his odds on Bovada and BetOnline have lengthened from where they were before he formally accepted the Republican nomination.

Here are the Presidential and Democratic nomination betting odds as of July 21.

How accurate have betting odds been in past Presidential elections?

The betting favorite has only lost twice since 1866, according to the Conversation.

The two upsets came in 1948, when Harry Truman (D) beat eight to one odds to defeat Thomas Dewey (R), and in 2016, when Trump overcame seven to two odds to beat Hillary Clinton (D).

Biden was the betting favorite in the 2020 race, holding the pole position with Oddscheker from May through November.
