Harold Hamm has donated $150 million to the University of Oklahoma to support diabetes research and broader health care work, in a gift the university says is the largest in its history. The donation makes Hamm OU’s largest individual donor, with his lifetime giving nearing $250 million.
OU said $100 million will fund the campus’s broader work, including training health care workers and recruiting researchers. Another $50 million will go to the Harold Hamm Diabetes Center, with $30 million for new director John Kirwan’s priorities and $20 million for capital improvements and research infrastructure.
The Oklahoma City health campus will be renamed the Harold Hamm Health Campus. Hamm said in a statement, 'I've spent my life believing that when you see an opportunity to change the future, you don't stand on the sidelines—you act.' He also said he hopes the gift helps make Oklahoma a place where the next great medical breakthrough happens.
Hamm said the cause is personal: he was diagnosed with diabetes in his 50s. More than 40 million Americans live with diabetes, according to the American Diabetes Association.
The gift builds on Hamm’s earlier support. His 2007 lead gift established the Harold Hamm Diabetes Center, and he has given more than $50 million to it since. OU said NIH research funding tied to the center has grown from $5 million to $33 million over that time. Hamm also created the Harold Hamm International Prize for Biomedical Research in Diabetes.
Hamm founded Continental Resources in 1967 at age 21 and still chairs the company, which has a $27 billion market cap. His net worth is estimated at nearly $18 billion.
His influence extends beyond philanthropy. This summer, he merged the Domestic Energy Producers Alliance with the Independent Petroleum Association of America, and an IPAA spokesperson told Politico he has 'expressed an interest' in becoming chair. Politico also reported that President Donald Trump has referred to Hamm as his 'original oil guy.'
The donation lands in a state with serious health care problems. Oklahoma ranks No. 49 in the nation for health care due to severe gaps in access, a high rate of uninsured adults, and poor health outcomes. The Oklahoma Hospital Association says there are critical shortages of health care workers across the state, and its president and CEO, Rich Rasmussen, said more than 90 hospitals in the state lose money on providing care to patients.
For free enterprise readers, the key fact is simple: private capital is moving where public systems have fallen short. Hamm’s gift is not a substitute for a functioning health care market, but it is a reminder that voluntary capital often builds faster than bureaucracy can budget. Capital rewards clear rules, real incentives, and measurable results.
At the same time, the Oklahoma case shows what happens when hospitals depend on shifting public payments and Congress cuts them. The taxpayer is already part of the story. Hamm is using private wealth to fill a gap that government has not closed.
