As of Friday morning Harris, who impressed with a direct attack on Biden, was tied with Warren on top of PredictIt, a market where participants bet on whether a candidate will, or will not, become the party's nominee.

On Bovada and BetOnline, which take a more traditional approach to reflect odds, Harris and Warren propelled themselves into the same tier as Biden, with Harris even becoming the favorite to win the nomination in least one market.

Another big climber was former Housing and Urban Development Secretary Julián Castro, who capitalized on his detailed immigration stances.

But Biden lost ground in two of the three betting markets being tracked by The Hill, after the former vice president was widely seen as having faltered on Thursday night's debate.

The Hill tracked three of the biggest markets on Wednesday, just hours before the start of the first of the two Democratic primary debates this week.

Here is how the 2020 candidates have shifted now that the debates have concluded.
