Market Discussion
As of August 31, 2026, Georgia Senator Jon Ossoff and Representative Alexandria Ocasio-Cortez have emerged as leading contenders for the 2028 Democratic presidential nomination in prediction markets, with Ossoff frequently holding the top spot, while former long-term frontrunner California Governor Gavin Newsom has seen his market odds decline significantly [1][2][3][4]. Political analysts characterize the 2028 Democratic primary as an open "invisible primary" with no official candidates, and potential hopefuls are focused on current duties despite active tracking by prediction markets [5][6][7][1][2][3]. The Democratic National Committee has proposed a new early-state primary calendar for 2028, selecting South Carolina, Nevada, New Hampshire, New Mexico, Michigan, and Virginia as the first six states to hold primaries, pending full DNC approval [8].
