One day after losing a closer-than-expected Senate race to incumbent Sen. Ted Cruz, Texas Democrat Beto O'Rourke is making a massive surge in online betting odds for the 2020 presidential election.

Immediately after O'Rourke's loss Tuesday night, a number of public figures, including Golden State Warriors head coach Steve Kerr and actress Alyssa Milano, called on the congressman to run for president in 2020.

O'Rouke has previously shot down any speculation of a 2020 run, but that didn't stop oddsmakers from drastically increasing his odds Wednesday.

OddsShark, a betting resource that tracks odds across a number of online betting sites currently gives O'Rourke +1000 odds to win the presidency in 2020, meaning a $100 bet would earn $1000 if he wins.

Prior to Wednesday, O'Rourke trailed big-name Democrats, including Sen. Kamala Harris of Calif., Vermont Sen. Bernie Sanders, former Vice President Joe Biden and Sen. Elizabeth Warren of Mass.

But after O'Rourke made significant jumps on major betting sites Bovada, Coral and Betfair among others, OddsShark now lists O'Rourke and Harris as the Democratic co-favorites with identical +1000 odds.

Sanders has the second-best odds at +1200, followed by Biden at +1400. After that, is Warren and New Jersey Sen. Cory Booker, who are tied at +2000.

Vice President Mike Pence also has +2000 odds to win the 2020 presidential election.

Harris had sole possession of first place for best odds among Democrats in the months leading up to the midterms.
