Vance's 2028 Republican nomination odds fell from 35% to 27% on Kalshi, while DeSantis's rose from 5% to 17%. The shifts followed Republican losses of both the House and Senate in Tuesday's midterm elections.
Why it matters
Prediction markets are one measure of how traders view the emerging 2028 field, and the moves reflect changing expectations after the midterms. DeSantis's rise followed his public break with Trump on several policy issues.
Kalshi prediction market prices showed Vance's Republican nomination odds falling from 35% to 27%, while DeSantis's rose from 5% to 17%. Democratic nomination odds for Ossoff rose from 17% to 22%, but these are trading snapshots that move with ongoing contract activity.

The details

Timeline

Tuesday, hours before polls opened: DeSantis publicly distanced himself from Trump on a podcast.
Wednesday: Prediction market odds shifted for Vance, DeSantis and Ossoff.
Political Context
Republican losses in the House and Senate midterms have prompted expectations to shift across the 2028 field, with market-based views now favoring a different set of contenders than before the vote. Critics of the party's direction, including DeSantis, argue that Trump's handling of the Iran war, gasoline prices and immigration enforcement warrants a different approach.
For voters, shifting odds on prediction markets reflect trader sentiment rather than official outcomes, so they offer a snapshot of expectations for the 2028 race. The changes may influence which Republican candidates receive donor attention and media coverage in the months ahead.
The takeaway
Prediction market odds move quickly with new information, so today's shifts for Vance, DeSantis and Ossoff may look different in coming weeks. Readers should treat them as one indicator of changing expectations rather than a settled forecast.
