Mike Mazzei, Charles McCall, Chip Keating and Gentner Drummond have collectively put more than $22 million of their own money into Oklahoma’s 2026 governor’s race, accounting for nearly three-quarters of all funds raised by their campaigns.
OKLAHOMA CITY – Republican candidates for governor have collectively loaned more than $22.4 million to their own campaigns, a staggering sum that now accounts for nearly three-quarters of the money raised by the four leading contenders in Oklahoma’s 2026 gubernatorial race.
Pre-primary reports filed with the Oklahoma Ethics Commission show Mike Mazzei, Charles McCall, Chip Keating and Gentner Drummond have loaned a combined $22.496 million to their campaigns through June 1.
The self-financing accounts for nearly 72 percent of the $31.36 million in total receipts reported by the four campaigns.
Mazzei leads the field by a wide margin, reporting $10.895 million in loans from Mike and Noel Mazzei to his campaign. Former House Speaker Charles McCall reported $5.601 million in candidate loans, while Chip Keating reported $3.5 million and Attorney General Gentner Drummond reported $2.5 million.
The loans are not bank financing. Schedule C disclosures identify the funds as candidate loans rather than financing from banks or third-party lenders.
The reports offer a glimpse into the financial resources behind a field dominated by candidates with substantial business backgrounds.
Mazzei, a former state senator from Tulsa, built his career in financial planning and wealth management. He founded Trinity Strategic Wealth, a Tulsa-based financial advisory firm. His campaign reported total receipts of $11.52 million, meaning nearly 95 percent of the money raised has come from loans provided by Mike and Noel Mazzei.
McCall, a longtime community banker from Atoka and the longest-serving speaker in Oklahoma House history, reported total receipts of $7.36 million. More than three-fourths of that money came from loans he made to his campaign.
Drummond, an attorney, rancher and businessman from Osage County, reported total receipts of $7.15 million. His $2.5 million in candidate loans represent about 35 percent of the money raised by his campaign, the lowest self-financing percentage among the four candidates.
Keating, an investor and businessman who previously served as Oklahoma secretary of public safety and as an Oklahoma Highway Patrol trooper, reported $5.33 million in total receipts, including $3.5 million in candidate loans.
The reports show the candidates have not only raised large sums but have also spent heavily. Combined expenditures by the four campaigns exceeded $29.5 million through the June 1 reporting period as candidates flooded television, digital platforms, mailboxes and campaign events ahead of the Republican primary.
The figures underscore how increasingly expensive statewide campaigns have become and how personal wealth has emerged as one of the defining factors in the race to succeed term-limited Gov. Kevin Stitt.
By the numbers:
• Mike Mazzei — $10.895 million in candidate loans; $11.52 million total receipts.
• Charles McCall — $5.601 million in candidate loans; $7.36 million total receipts.
• Chip Keating — $3.5 million in candidate loans; $5.33 million total receipts.
• Gentner Drummond — $2.5 million in candidate loans; $7.15 million total receipts.
Combined, the four campaigns reported $31.36 million in total receipts and $22.496 million in candidate loans through June 1.
