Full articleGeorge Bruce Kaiser (born July 29, 1942) is an American billionaire businessman and philanthropist headquartered in Tulsa, Oklahoma. He chairs BOK Financial Corporation, a bank holding company with over $46 billion in assets, of which he owns approximately 59%, and serves as president and principal owner of GBK Corporation, parent to the oil and gas exploration firm Kaiser-Francis Oil Company, which he assumed control of in the 1960s.
Kaiser's fortune, valued at $14.4 billion as of October 2025, stems from expanding his family's oil business and acquiring the Bank of Oklahoma in 1991 for $60 million, transforming it into a regional powerhouse.
A signatory to the Giving Pledge, Kaiser has committed the majority of his wealth to philanthropy via the George Kaiser Family Foundation, established in 1999 to address intergenerational poverty through targeted investments in early childhood education, family economic security, and community development, including a $350 million donation toward Tulsa's Gathering Place riverfront park.
Notable among his ventures was an investment in Solyndra, a solar panel manufacturer that received over $500 million in federal loan guarantees before declaring bankruptcy in 2011, prompting investigations into potential influence from Kaiser's donations to Democratic causes and communications with Obama administration officials.
In brief
George Kaiser runs a bank in a city that still remembers oil as a personality. BOK Financial is the public company; the quieter work is a philanthropy that treats early childhood as infrastructure.
He is a billionaire who stayed in Tulsa. That choice is itself a kind of thesis: capital does not have to leave the place that made it.
