The candidates for Governor were required to file post-primary campaign finance reports, showing all the contributions their campaigns had brought in just prior to and after the primary election, when donors can reach back into their pockets and max out again before the General Election. Here’s a look at what those filings, which cover the 7 weeks from April 16 through June 5, 2026 show.

Fundraising

Amy Acton out-raised Vivek Ramaswamy in the post-primary period: $5.4 million to $4.6 million. This comes after she also out-raised him in the pre-primary period covering January 1 through April 15 of 2026. Ramaswamy held a substantial fundraising advantage throughout 2025.

Spending

Ramaswamy spent $8.6 million while raising $4.6 million, meaning that he spent nearly twice what he raised from donors. Acton spent $2.2 million while raising $5.4 million, or about 42 cents of every dollar raised.

Cash on hand

Thanks to that aggressive spending by Ramaswamy, he ends the post-primary period with $26.7 million in cash on hand, down $5 million from the pre-primary filing. Acton reported $8.1 million in cash on hand. Ramaswamy’s $18.6 million cash advantage is down from $25.7 million in the pre-primary report, a gap that narrowed by $7.1 million in just 7 weeks.

His filing also shows $25.7 million in loans made to his committee, meaning nearly his entire cash-on-hand balance is money he lent himself.

Where the money came from

Ramaswamy

Ramaswamy raised $4,585,502 in the post-primary period. Nearly 62% ($2.83 million) came from Ohio donors. His largest out-of-state sources were Florida ($348,000), Texas ($221,000), and California ($172,000). More than a third of his total (37.3%) came from just 125 donations of $10,000 or more.

Acton

Acton raised $5,363,781 in the post-primary period. Over 68% ($3.66 million) came from Ohioans. Her largest out-of-state sources were California ($324,000), New York ($201,000), and Washington D.C. ($152,000). Just 20% of her total came from donations of $10,000 or more, spread across 54 contributions.

Notable donor clusters

Founders of World Liberty Financial, the Trump family's cryptocurrency venture, gave a combined $116,000 to Ramaswamy's campaign in contributions clustered around primary day. The donors include Chase Herro and Zak Folkman, who co-founded and operate the venture day-to-day, Zachary Witkoff, son of Trump Middle East envoy Steve Witkoff, and Paxos CEO Charles Cascarilla. The Trump family is entitled to 75% of the venture's token sale revenue; it has generated more than $57 million for Trump personally. Ramaswamy personally holds Bitcoin and Ethereum and has backed legislation that would direct Ohio public pension funds into cryptocurrencies.

Six executives at CareSource, one of Ohio's largest Medicaid managed care organizations, gave a combined $42,536 in the post-primary period. As governor, Ramaswamy would oversee Medicaid policy and state health contracting.

The American Electric Power political action committee gave $16,000. The Charter Communications Ohio PAC gave $12,750. AEP has active rate cases before the Public Utilities Commission of Ohio; Charter is a state-regulated broadband provider.

Two partners at Brennan, Manna & Diamond, the law firm co-founded by the late David Brennan, architect of Ohio's for-profit charter school industry, gave a combined $30,000. The firm still practices education law.

Notable donors — Acton

Acton had 19 donors at or above the $16,615 maximum contribution threshold. Seventeen of the 19 are Ohio residents. The list includes plaintiff's attorneys Carrie and Thomas Bevan ($48,715 combined), retirees, investors, a nonprofit executive, and a communications firm owner. No industry cluster stands out.
