Greg Brockman Is Now Running OpenAI's Day-to-Day Operations

Key points

• Greg Brockman, OpenAI's president and co-founder, now oversees all four of the company's main business divisions, including ChatGPT and Codex, its AI coding tool.
• At least five senior executives have left OpenAI since April 2025, with each departure expanding Brockman's authority.
• CEO Sam Altman has shifted his focus to long-range strategy and a planned stock market listing, leaving Brockman to handle daily operations.
• OpenAI faces pressure to reach profitability while competing with Anthropic for business customers and planning one of tech's most anticipated public offerings in years.

Greg Brockman built his reputation quietly. He dropped out of MIT to become the chief technology officer at Stripe, the payments company, during its early high-growth years, then left in 2015 to co-found OpenAI alongside Sam Altman and Ilya Sutskever. For most of the decade since, he worked behind the scenes. Now he is very much in front.

According to reporting by The Verge, Brockman effectively runs OpenAI's day-to-day operations. He controls ChatGPT, the company's flagship AI assistant used by hundreds of millions of people. He controls Codex, an AI tool that writes and edits computer code. He also oversees both the consumer and enterprise (business-focused) product arms of the company. That is all four of OpenAI's main divisions under one person.

How did one person accumulate this much authority?

The short answer: a string of high-profile departures and a loyalty that dates back to a boardroom crisis.

In November 2023, OpenAI's board fired Sam Altman without warning. Brockman quit the same day, refusing to stay without his co-founder. Within days, hundreds of OpenAI employees threatened to walk out unless Altman was reinstated. He came back. The board members who voted to remove him were replaced. Brockman returned with him.

That moment changed their relationship. Altman now trusts Brockman in a way that pre-dates the crisis, and that trust has translated directly into authority.

Since April 2025, several senior figures have departed, including Bill Peebles, who ran Sora, OpenAI's video-generation tool, and Kevin Weil, who was vice president of the company's science division after previously serving as head of product at Instagram. With each exit, more responsibility has landed with Brockman.

What does this mean for OpenAI's products?

For ordinary users, the practical effect is that one person now shapes the direction of almost everything OpenAI ships. ChatGPT, which many people use daily for writing, research and answering questions, falls under Brockman's oversight.

The consolidation comes at a delicate moment. OpenAI is preparing for a stock market listing, which requires demonstrating a clear path to profit. The company is also losing ground to Anthropic, the rival AI lab, in the market for business customers. Anthropic's Claude models, a competing family of AI assistants, have been gaining adoption among corporate buyers.

Altman, meanwhile, is focused on the bigger picture: the IPO, long-range strategy, and the company's stated ambition to build AI that matches or exceeds human intelligence across virtually every task. That leaves Brockman as the person deciding, week to week, what gets built and shipped.

What happens next?

Brockman is now the most operationally powerful person at OpenAI, whether or not his name appears at the top of the org chart. How he handles that position will shape whether OpenAI can hold its lead in a market that is moving very fast and attracting enormous competition.

For users, no immediate changes are announced. But the executive steering the products you use has quietly shifted.
