Ossoff Tops Kalshi 2028 Democratic Nomination Market
Betting markets on Kalshi and Polymarket now place Georgia Senator Jon Ossoff at the front of the 2028 Democratic presidential field.
Updated on Nov. 4, 2026 in Elections
Jon Ossoff rose to the top of Kalshi's 2028 Democratic presidential nomination betting market, with 26% of bettors choosing him, ahead of Alexandria Ocasio-Cortez at 14% and Gavin Newsom at 13%. He also led the Polymarket market at 24%, where Ocasio-Cortez and Newsom were each at 15%.
Why it matters
The shift follows the Democratic midterm results, in which Democrats took control of the House and the Senate. Former President Barack Obama praised Ossoff at a campaign rally the prior week, a development that bettors have folded into their standings.
Kalshi bettors placed Ossoff at 26% against 14% for Ocasio-Cortez and 13% for Newsom, while Polymarket bettors placed him at 24% against 15% each for Ocasio-Cortez and Newsom. Market shares reflect betting positions rather than polling, and no formal candidacy has been declared.

Elections Context
Prediction-market leaderboards for the 2028 Democratic nomination on Kalshi and Polymarket now place Jon Ossoff first, a shift that follows the midterm results. The movement reflects bettor positions in those two markets rather than an official declaration of any candidate.
Prediction-market standings are a snapshot of bettor positions and do not determine who will run or win the nomination. Readers following the 2028 race should treat these shares as sentiment indicators rather than forecasts.
The takeaway
Betting-market leaders can shift quickly after a major election, so early standings reflect sentiment more than settled support. Watching how the shares move over the coming months will show whether Ossoff's lead holds.
