Tuesday Afternoon Update

Vermont Senator Bernie Sanders was a prohibitive favorite to win the 2020 Democratic Primary last week entering the Nevada caucus, and his strong performance and victory Saturday has increased his odds even further.

He's now the odds-on favorite to win the nomination at -125 odds (bet $125 to win $100), with a juice-free implied probability of 51.3%. For reference, he was at 45.0% prior to the Nevada results.

Still in second place in the betting market is former NYC mayor Michael Bloomberg, who didn't really budge. He was at a 20.0% implied probability a week ago; he's still at +350 today, or a 20.5% implied probability.

The biggest movement was with former VP Joe Biden, who jumped into third place and now has an implied probability of 10.2% to win the nomination. Pete Buttigieg dropped down to +900 or 9.2% probability, and Elizabeth Warren and Amy Klobuchar also saw significant drops.

The Warren number is interesting given that she was considered the winner of last week's Nevada Democratic debate, and she raised millions of dollars off that performance. Apparently the betting market isn't buying a rise.

Biden could be a bit undervalued by the betting market right now: He's now a slight favorite to win the South Carolina primary this Saturday, and if he beats out Sanders, this will likely turn into a two-man race; Biden's odds will likely jump at that point as the candidates push toward Super Tuesday on March 3.

But if Sanders — who is a slight underdog to Biden in South Carolina — wins South Carolina and shows solid support from African American voters, he will become a (rightfully) huge favorite to win the nomination.
