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.
Circle, the company behind the USDC stablecoin, has filed for an initial public offering with the U.S. Securities and Exchange Commission.
The S1 lays the groundwork for Circle’s long-anticipated entry into the public markets.
While the filing does not yet disclose the number of shares or a price range, sources told Fortune that Circle plans to move forward with a public filing in late April and is targeting a market debut as early as June.
JPMorgan Chase and Citi are reportedly serving as lead underwriters, and the company is seeking a valuation between $4 billion and $5 billion, according to Fortune.
This marks Circle’s second attempt at going public. A prior SPAC merger with Concord Acquisition Corp collapsed in late 2022 amid regulatory challenges. Since then, Circle has made strategic moves to position itself closer to the heart of global finance — including the announcement last year that it would relocate its headquarters from Boston to One World Trade Center in New York City.

Circle is best known as the issuer of USDC, the world’s second-largest stablecoin by market capitalization.
Pegged one-to-one to the U.S. dollar and backed by cash and short-term Treasury securities, USDC has roughly $60 billion in circulation.
Circle is best known as the issuer of USDC, the world’s second-largest stablecoin by market capitalization.
Pegged one-to-one to the U.S. dollar and backed by cash and short-term Treasury securities, USDC has roughly $60 billion in circulation. It makes up about 26% of the total market cap for stablecoins, behind Tether‘s 67% dominance. Its market cap has grown 36% this year, however, compared with Tether’s 5% growth.
Coinbase CEO Brian Armstrong said on the company’s most recent earnings call that it has a “stretch goal to make USDC the number 1 stablecoin.”
The company’s push into public markets reflects a broader moment for the crypto industry, which is navigating renewed political favor under a more crypto-friendly U.S. administration. The stablecoin sector is ramping up as the industry grows increasingly confident that the crypto market will get its first piece of U.S. legislation passed and implemented this year, focusing on stablecoins.
Stablecoins’ growth could have investment implications for crypto exchanges like Robinhood and Coinbase as they integrate more of them into crypto trading and cross-border transfers. Coinbase also has an agreement with Circle to share 50% of the revenue of its USDC stablecoin.
The stablecoin market has grown about 11% so far this year and about 47% in the past year, and has become a “systemically important” part of the crypto market, according to Bernstein. Historically, digital assets in this sector have been used for trading and as collateral in decentralized finance (DeFi), and crypto investors watch them closely for evidence of demand, liquidity and activity in the market.
More recently, however, rhetoric around stablecoins’ ability to help preserve U.S. dollar dominance – by exporting dollar utility internationally and ensuring demand for U.S. government debt, which backs nearly all dollar-denominated stablecoins – has grown louder.
A successful IPO would make Circle one of the most prominent crypto-native firms to list on a U.S. exchange — an important signal for both investors and regulators as digital assets become more entwined with the traditional financial system.

Hims & Hers Health shares closed up 5% on Tuesday after the company announced patients can access Eli Lilly‘s weight loss medication Zepbound and diabetes drug Mounjaro, as well as the generic injection liraglutide, through its platform.
Zepbound, Mounjaro and liraglutide are part of the class of weight loss medications called GLP-1s, which have exploded in popularity in recent years. Hims & Hers launched a weight loss program in late 2023, but its GLP-1 offerings have evolved as the company has contended with a volatile supply and regulatory environment.
Lilly’s weekly injections Zepbound and Mounjaro will cost patients $1,899 a month, according to the Hims & Hers website. The generic liraglutide will cost $299 a month, but it requires a daily injection and can be less effective than other GLP-1 medications.
“As we look ahead, we plan to continue to expand our weight loss offering to deliver an even more holistic, personalized experience,” Dr. Craig Primack, senior vice president of weight loss at Hims & Hers, wrote in a blog post.
A Lilly spokesperson said in a statement that the company has “no affiliation” with Hims & Hers and noted that Zepbound is available at lower costs for people who are insured for the product or for those who buy directly from the company.
In May, Hims & Hers started prescribing compounded semaglutide, the active ingredient in Novo Nordisk‘s GLP-1 weight loss medications Ozempic and Wegovy. The offering was immensely popular and helped generate more than $225 million in revenue for the company in 2024.
But compounded drugs can traditionally only be mass produced when the branded medications treatments are in shortage. The U.S. Food and Drug Administration announced in February that the shortage of semaglutide injections products had been resolved.
That meant Hims & Hers had to largely stop offering the compounded medications, though some consumers may still be able to access personalized doses if it’s clinically applicable.
During the company’s quarterly call with investors in February, Hims & Hers said its weight loss offerings will primarily consist of its oral medications and liraglutide. The company said it expects its weight loss offerings to generate at least $725 million in annual revenue, excluding contributions from compounded semaglutide.
But the company is still lobbying for compounded medications. A pop up on Hims & Hers’ website, which was viewed by CNBC, encourages users to “use your voice” and urge Congress and the FDA to preserve access to compounded treatments.
With Tuesday’s rally, Hims and Hers shares are up about 27% in 2025 after soaring 172% last year.

Meta’s head of artificial intelligence research announced Tuesday that she will be leaving the company.
Joelle Pineau, the company’s vice president of AI research, announced her departure in a LinkedIn post, saying her last day at the social media company will be May 30.
Her departure comes at a challenging time for Meta. CEO Mark Zuckerberg has made AI a top priority, investing billions of dollars in an effort to become the market leader ahead of rivals like OpenAI and Google.
Zuckerberg has said that it is his goal for Meta to build an AI assistant with more than 1 billion users and artificial general intelligence, which is a term used to describe computers that can think and take actions comparable to humans.
“As the world undergoes significant change, as the race for AI accelerates, and as Meta prepares for its next chapter, it is time to create space for others to pursue the work,” Pineau wrote. “I will be cheering from the sidelines, knowing that you have all the ingredients needed to build the best AI systems in the world, and to responsibly bring them into the lives of billions of people.”

Pineau was one of Meta’s top AI researchers and led the company’s fundamental AI research unit, or FAIR, since 2023. There, she oversaw the company’s cutting-edge computer science-related studies, some of which are eventually incorporated into the company’s core apps.
She joined the company in 2017 to lead Meta’s Montreal AI research lab. Pineau is also a computer science professor at McGill University, where she is a co-director of its reasoning and learning lab.
Some of the projects Pineau helped oversee include Meta’s open-source Llama family of AI models and other technologies like the PyTorch software for AI developers.
Pineau’s departure announcement comes a few weeks ahead of Meta’s LlamaCon AI conference on April 29. There, the company is expected to detail its latest version of Llama. Meta Chief Product Officer Chris Cox, to whom Pineau reported to, said in March that Llama 4 will help power AI agents, the latest craze in generative AI. The company is also expected to announce a standalone app for its Meta AI chatbot, CNBC reported in February.
“We thank Joelle for her leadership of FAIR,” a Meta spokesperson said in a statement. “She’s been an important voice for Open Source and helped push breakthroughs to advance our products and the science behind them.”
Pineau did not reveal her next role but said she “will be taking some time to observe and to reflect, before jumping into a new adventure.”
