OpenAI CFO Sarah Friar is looking to reassure its investors that the richly valued artificial intelligence startup is still in a strong position and is poised to close a big funding round soon, despite losing top talent this week.
In an email to OpenAI’s investors seen by CNBC, Friar addressed the departure of Chief Technology Officer Mira Murati, who announced her departure on Wednesday. Later that day, Sam Altman said two top research executives, Bob McGrew and Barret Zoph, were also leaving.
“I wanted to personally reach out following the news of Mira’s departure from OpenAI,” Friar wrote in the letter, which was viewed by CNBC. “While leadership changes are never easy, I want to ensure you have the full context.”
Friar added that, “We are incredibly proud of everything she’s helped build,” and said the San Francisco-based company still has a “talented leadership bench” to compete.
OpenAI, which is backed by Microsoft and recently partnered with Apple on its AI for iPhones, is in the midst of closing a $6.5 billion funding round, which should value the company at roughly $150 billion, according to sources familiar with the matter. Thrive Capital is leading the round, and plans to invest $1 billion, according to sources.
Friar said in the email that the funding round was oversubscribed and would close by next week. She said the team plans to host a series of calls with investors to introduce the group to key leaders from product and research teams.
“Collectively, we remain laser-focused on bringing AI to everyone and building sustainable revenue models that fuel our operations and deliver value to our investors and employees,” Friar wrote. The company is “excited for you to be with us as we enter our next chapter,” she wrote.
OpenAI declined to comment on the email.
Murati’s departure comes after six and a half years at the company. She briefly served as interim CEO last year after the board of directors abruptly fired Altman. When Altman was quickly reinstated, Murati returned to the role of CTO.

The company was already dealing with the loss of key executives. Co-founder John Schulman and safety chief Jan Leike left to join rival Anthropic. Co-founder Ilya Sutskever left to start another AI company , while another founder, Greg Brockman, is on a leave of absence.
Friar said Mark Chen will step into the role of of senior vice president of research, and leaders like Kevin Weil, who joined from Meta, and Srinivas Narayanan are the “right people to keep pushing the boundaries of innovation.”
Friar was formerly CEO of Nextdoor, and before that CFO at Block, formerly Square.
Also on Thursday, at an all-hands meeting, Altman denied that there are plans for him to receive a “giant equity stake” in the company, calling reports of such a development “just not true,” according to a person who was in attendance.
Altman and Friar both said at the meeting, conducted by video, that investors have raised concerns about Altman not having equity in the company that he co-founded almost nine years ago, said the person, who asked not to be named because the gathering was only for employees.

Last week’s liftoff also coincided with President Donald Trump‘s “space superiority” executive order, signed on Friday, that aims to create a permanent U.S. base on the moon.
Investors have also gained more clarity on the future of NASA following a whirlwind drama since Trump won the election.
Last week, the Senate confirmed Jared Isaacman as NASA administrator more than a year after he was first nominated to the position.
Trump withdrew the nomination from the Elon Musk ally earlier this year amid a public fallout, but renominated Isaacman in November.
Transportation Secretary Sean Duffy was tapped to temporarily run the space agency in the interim.
Google parent Alphabet on Monday announced it will acquire Intersect, a data center and energy infrastructure company, for $4.75 billion in cash in addition to the assumption of debt.
Alphabet said Intersect’s operations will remain independent, but that the acquisition will help bring more data center and generation capacity online faster.
In recent years, Google has been embroiled in a fierce competition with artificial intelligence rivals, namely OpenAI, which kick-started the generative AI boom with the launch of its ChatGPT chatbot in 2022. OpenAI has made more than $1.4 trillion of infrastructure commitments to build out the data centers it needs to meet growing demand for its technology.
With its acquisition of Intersect, Google is looking to keep up.
“Intersect will help us expand capacity, operate more nimbly in building new power generation in lockstep with new data center load, and reimagine energy solutions to drive US innovation and leadership,” Sundar Pichai, CEO of Google and Alphabet, said in a statement.
Google already had a minority stake in Intersect from a funding round that was announced last December. In a release at the time, Intersect said its strategic partnership with Google and TPG Rise Climate aimed to develop gigawatts of data center capacity across the U.S., including a $20 billion investment in renewable power infrastructure by the end of the decade.
Alphabet said Monday that Intersect will work closely with Google’s technical infrastructure team, including on the companies’ co-located power site and data center in Haskell County, Texas. Google previously announced a $40 billion investment in Texas through 2027, which includes new data center campuses in the state’s Haskell and Armstrong counties.
Intersect’s operating and in-development assets in California and its existing operating assets in Texas are not part of the acquisition, Alphabet said. Intersect’s existing investors including TPG Rise Climate, Climate Adaptive Infrastructure and Greenbelt Capital Partners will support those assets, and they will continue to operate as an independent company.
Alphabet’s acquisition of Intersect is expected to close in the first half of 2026, but it is still subject to customary closing conditions.
