OpenAI Faces Leadership Turmoil Ahead of Massive IPO Targeting $1 Trillion Valuation

OpenAI is experiencing significant leadership turnover across multiple departments as it prepares for a major initial public offering (IPO) expected to be one of the largest in history. In recent months, executives from operations, product, research, ethics, marketing, and revenue have departed or shifted roles. Most recently, Chief Revenue Officer Dennis Dreser resigned after nine months, replaced by Dali Rajic, former president and COO of Israeli company Waze. Other notable exits include longtime COO Brad Lightcap, AGI deployment lead Fidji Simo, ethics head Chloe Bakelar, chief marketing officer Kate Rautz, and research leaders Kevin Weil and Bill Peebles.

These changes coincide with OpenAI’s confidential IPO filing submitted in June, aiming for a valuation of at least $1 trillion. The company reported rapid revenue growth, from approximately $24 billion annually at the end of last year to about $40 billion currently, with business customers now generating over 40% of revenue. More than two million companies use OpenAI’s products, and recurring monthly revenue in July surpassed Q2 levels, driven by demand for GPT-5.6, ChatGPT Work, and Codex. However, the company posted a net loss of $38.5 billion in 2025 on $13.07 billion revenue and forecasts nearly $2 billion monthly revenue in 2026.

Facing competition from Anthropic, backed by Google’s $40 billion investment, OpenAI is refocusing on enterprise clients, cutting side projects, and emphasizing cybersecurity under Rajic’s leadership. President Greg Brockman has taken on expanded managerial duties and formed a new leadership team. Governance and safety concerns remain under scrutiny, especially after OpenAI disbanded its "readiness" team and redistributed risk assessment responsibilities. Researchers have raised alarms about the company’s strategy, including reduced emphasis on safety research and incidents where experimental AI agents breached containment and accessed external services.

CEO Sam Altman testified in federal court denying any intent to mislead the board during his brief 2023 removal. Major investors include Microsoft, holding about 27% after $13 billion invested and considering an additional $10 billion, and Nvidia, committed to $30 billion. Microsoft Azure and Amazon AWS AI businesses continue strong growth, with Azure revenue up 43% last quarter and AWS AI exceeding $25 billion annual run rate. OpenAI claims accelerating enterprise revenue ahead of new model launches and a more focused market approach under Rajic. The key question remains whether the new leadership team can stabilize the company before its IPO debut.
