According to AdImpact’s Tuesday ranking, the 2026 governor’s race ranks seventh on the list of all-time most expensive nonpresidential races.
Michigan Senate
In eighth place on the all-time list, as of Tuesday, Michigan’s open Senate race had drawn $347.5 million in ad spending and reservations, as Democrat Abdul El-Sayed faces off against former Rep. Mike Rogers (R-Mich.) for retiring Sen. Gary Peters‘s (D-Mich.) seat.
The primaries alone saw $98.2 million by July 31, a few days before the election, already more than tripling the state’s previous record for a nonpresidential primary. That made it the third most expensive Senate primary on record, according to AdImpact, behind this year’s Senate race in Texas and the 2022 Senate race in Arizona. Much of that spending went to El-Sayed’s Democratic opponent, Rep. Haley Stevens (D-Mich.).
Georgia governor
The state’s 2020 special election for Senate ranked 10th in AdImpact’s tally, with $303.5 million spent on that race. But this year’s contest for governor falls not far behind, with $297 million spent as of Monday on aired ads and future reservations. That total is largely driven by the $268.5 million in GOP spending — mostly from the personal fortune of Republican nominee Rick Jackson.
Much of the total spending was dished out during the primaries. By mid-June, just days before the GOP runoff, the race had already drawn more than $162 million in advertising, according to AdImpact data analyzed by the Wesleyan Media Project. Republican candidates accounted for roughly $133.6 million of that.
Jackson, a healthcare executive, now faces former Atlanta Mayor Keisha Lance Bottoms (D) in the race to succeed term-limited Gov. Brian Kemp (R). Polling shows the race in a statistical dead heat.
