In 2006, OSU became the recipient of a gift of $165 million from alumnus T. Boone Pickens to the university's athletic department, and in 2008 received another gift from Pickens of $100 million for endowed academic chairs. It was the largest gift for academics ever given in the state. Ethical concerns have been raised in media reports about the propriety of how some of the Pickens gifts have been made, immediately returned to Pickens, and then placed in hedge funds owned by Pickens' companies In February 2010, Pickens announced that he was pledging another $100 million to fund a scholarship endowment as part of a $1 billion fund-raising campaign titled "Branding Success." The pledge brought the total pledged or contributed to OSU by Pickens to over $500 million.

Current university-owned housing options include 31 residence halls, more than 15 dining options, and six family-first apartment complexes. In recent years, on-campus housing has been undergoing significant transformation. Student living was previously dominated by traditional residence halls; however, apartment-style buildings now comprise approximately half of the living quarters. In 2005, the high-rise Willham North and South residence halls that once dominated the Stillwater skyline were demolished and replaced with the Village suites on its site. Iba Hall, another traditional hall, was closed in 2007, but was reopened in 2011 due to an increase of incoming freshman.
