Ossoff is the only Democratic senator up for reelection in a state Trump won, making Georgia's 2026 U.S. Senate race the most competitive and most expensive in the country. The market for him as first Democrat to announce a presidential run collapsed from 67¢ to 14¢, suggesting traders see his Senate seat as vulnerable rather than a launching pad for higher office.

Sabato's Crystal Ball moved the race toward Ossoff, reclassifying it from a pure toss-up to "Leans Democrat," but Republicans hope to topple Ossoff in what is likely to become one of 2026's most competitive, and expensive, Senate races. The dramatic odds shift reflects growing uncertainty about whether Ossoff can generate the turnout needed to hold his seat, let alone position himself for a 2028 presidential campaign.
