OpenAI co-founder and president Greg Brockman has taken effective control of day-to-day operations at the company, according to a report published by The Verge on August 20, 2026, as a sustained wave of executive departures has concentrated authority in his hands. Sam Altman remains CEO, but Brockman is now running the show operationally.
- Brockman now oversees product strategy and OpenAI's entire scaling arm, making him the de facto day-to-day leader
- A string of high-profile departures since April - including COO Brad Lightcap and CEO of AGI deployment Fidji Simo - cleared the path for his expanded role
- Sam Altman remains CEO, but Brockman's stake in the company is worth nearly $30 billion based on his 2017 target of $1 billion
Brockman’s title - president and co-founder - has not changed in years, yet his actual responsibilities have grown substantially. He first picked up additional authority in April when Fidji Simo, OpenAI’s CEO of AGI deployment, went on medical leave; Brockman stepped in to lead all product work, including the company’s super app efforts. A further executive reorganisation the following month, aimed at growing revenue, extended his remit to OpenAI’s entire “scaling” arm, giving him authority over virtually every part of the company’s commercial operation. Simo’s official departure in July, arriving just weeks after OpenAI filed to go public, locked that arrangement in place.

The restructuring has been driven partly by an unusually high rate of exits at the senior level. April alone saw the departure of Bill Peebles, former head of Sora; Kevin Weil, VP of OpenAI’s science arm; and Srinivas Narayanan, CTO of B2B applications, alongside Simo and CMO Kate Rouch, both of whom cited medical reasons. The departures did not stop there. Earlier in August, chief revenue officer Denise Dresser - who had absorbed a significant number of responsibilities after the April shakeups - left after just eight months. Days later, Brad Lightcap, OpenAI’s longtime COO who had most recently been working on “special projects,” announced he would leave to start “something new.” OpenAI did not respond to a request for comment on the changes.
The consolidation of power around Brockman comes as OpenAI navigates an exceptionally turbulent period. The company spent months in a jury trial against former co-founder Elon Musk, faced a trade secrets lawsuit from Apple, and dealt with scrutiny after an unreleased model reportedly hacked a rival AI company - all while preparing for an IPO.
Brockman has been part of OpenAI from the start, described in early accounts as an “engineering workhorse” who built the scaled-up systems needed to train its models. A personal journal entry from 2017, since made public, recorded his ambition plainly: “Financially what will take me to $1B?” His current stake in OpenAI is worth nearly 30 times that figure, according to The Verge’s reporting.
