OpenAI confirmed that multiple senior executives have left the company, including data centers head Chris Malone, as part of a broader restructuring effort ahead of a confidential filing for an initial public offering. OpenAI, known for its GPT-5.6 model and a desktop application that has added roughly 15 million users in the past two months, filed for an IPO in June, according to its disclosures. The company has experienced several high‑level departures since the beginning of the year, including the chief operating officer, chief revenue officer, chief marketing officer, and various team leads. Malone departed last week after joining OpenAI in March 2025, a move that followed a reorganization of the infrastructure team in which vice president Sachin Katti now leads the group, according to a TechCrunch report. Malone reported directly to president Greg Brockman before the restructuring. Other departures have been linked to health issues or to the company's effort to cut side projects and focus on revenue‑generating initiatives, a factor cited by several analysts. Brockman, who was relieved of most managerial duties in 2019 when Sam Altman became CEO, has resumed a more central role, with infrastructure and product teams now reporting to him, Thibault Sottiaux, who leads the company’s API and app offerings, told TechCrunch. The company declined to comment on the broader changes, but analysts noted that the turnover coincides with OpenAI's IPO filing and its need to improve profitability and reduce costs. OpenAI's financial trajectory shows growing revenue alongside increasing losses, and its IPO timeline is expected to move forward after the typical five‑month period for confidential filings, a timeline SpaceX followed in less than two months. The succession of departures and internal reallocation of authority may test OpenAI's leadership continuity as it prepares for a public market debut.
