OpenAI Appoints Mike Liberatore as Business Finance Officer

OpenAI has appointed Mike Liberatore, formerly the Chief Financial Officer of Elon Musk’s company xAI, as its new Business Finance Officer. Liberatore will work with Chief Financial Officer Sarah Friar and President Greg Brockman to guide the company’s financial strategy and oversee the scaling of its computing infrastructure.

In announcing the appointment, OpenAI emphasized that Liberatore’s role will center on strengthening the company’s financial operations at a time when it is continuing to expand capacity. Computing infrastructure has become one of the organization’s largest commitments, and effective management of financial resources is viewed internally as essential for sustaining growth.

Sam Altman, OpenAI’s co-founder and CEO, said in a statement, “Mike brings operational expertise and financial insight that will help OpenAI as we continue to scale our infrastructure and capabilities.”

Liberatore joins OpenAI after leaving xAI in July 2025. His short tenure at Musk’s company lasted only a few months, a period during which he managed its financial planning and early investment activity. Before xAI, Liberatore held senior finance roles at Airbnb, where he contributed to managing budgets and overseeing operational spending in a large-scale technology business. His background combines both startup experience and established corporate leadership, giving him a breadth of perspective on financial governance.
