OpenAI co-founder Ilya Sutskever said Tuesday that he’s leaving the Microsoft-backed startup.
“I am excited for what comes next — a project that is very personally meaningful to me about which I will share details in due time,” Sutskever wrote in an X post on Tuesday.
The departure comes months after OpenAI went through a leadership crisis in November involving co-founder and CEO Sam Altman.
In November, OpenAI’s board said in a statement that Altman had not been “consistently candid in his communications with the board.” The issue quickly caqme to look more complex. The Wall Street Journal and other media outlets reported that Sutskever came to focus on ensuring that artificial intelligence would not harm humans, while others, including Altman, were eager to push ahead with delivering new technology.
Almost all of OpenAI’s employees signed an open letter saying they would leave in response to the board’s action. Days later, Altman was back at the company, and board members Helen Toner, Tasha McCauley and Sutskever, who had voted to oust Altman, were out. Adam D’Angelo, who had also voted to push out Altman, stayed on the board.
When Altman was asked about Sutskever’s status on a Zoom call with reporters at the time, he said there were no updates to share. “I love Ilya… I hope we work together for the rest of our careers, my career, whatever,” Altman said. “Nothing to announce today.”
On Tuesday, Altman shared his thoughts as Sutskever leaves.
“This is very sad to me; Ilya is easily one of the greatest minds of our generation, a guiding light of our field, and a dear friend,” Altman wrote on X. “His brilliance and vision are well known; his warmth and compassion are less well known but no less important.” Altman said research director Jakub Pachocki, who has been at OpenAI since 2017, will replace Sutskever as chief scientist.
OpenAI has announced new board members, including former Salesforce co-CEO Bret Taylor and former Treasury Secretary Larry Summers. Microsoft obtained a nonvoting board observer position.
In March, OpenAI announced its new board and the wrap-up of an internal investigation by U.S. law firm WilmerHale into the events leading up to Altman’s ouster. Altman rejoined OpenAI’s board, and three new board members were announced: Dr. Sue Desmond-Hellmann, former CEO of the Bill and Melinda Gates Foundation; Nicole Seligman, former EVP and Global General Counsel of Sony and President of Sony Entertainment; and Fidji Simo, CEO and Chair of Instacart.
The three new members will “work closely with current board members Adam D’Angelo, Larry Summers and Bret Taylor as well as Greg, Sam, and OpenAI’s senior management,” according to a company release in March.
News of Sutskever’s departure comes a day after OpenAI launched a new AI model and desktop version of ChatGPT, along with an updated user interface, the company’s latest effort to expand use of its popular chatbot.
The update brings the GPT-4 model to everyone, including OpenAI’s free users, technology chief Mira Murati said Monday in a livestreamed event. She added that the new model, GPT-4o, is “much faster,” with improved capabilities in text, video and audio. OpenAI said it eventually plans to allow users to video chat with ChatGPT. “This is the first time that we are really making a huge step forward when it comes to the ease of use,” Murati said.
In 2015, Altman and Tesla CEO Elon Musk, another OpenAI co-founder, wanted Sutskever, then a research scientist at Google, to become the budding startup’s top scientist, according to the lawsuit Musk filed against OpenAI in March.
“Dr. Sutskever went back and forth on whether to leave Google and join the project, but it was ultimately a call from Mr. Musk on the day OpenAI, Inc. was publicly announced that convinced Dr. Sutskever to commit to joining the project as OpenAI, Inc.’s Chief Scientist,” the legal filing said.

The wave of capital pouring into artificial intelligence infrastructure is far from peaking, said Ben Powell, chief investment strategist for APAC at BlackRock, arguing the sector’s “picks and shovels” suppliers — from chipmakers to energy producers and copper-wire manufacturers — remain the clearest winners as hyperscalers race to outspend one another.
The surge in AI-related capital expenditure shows no sign of slowing as tech giants push aggressively to secure an edge in what they see as a winner-takes-all contest, Powell told CNBC Monday on the sidelines of the Abu Dhabi Finance Week.
“The capex deluge continues. The money is very, very clear,” he said, adding that BlackRock is focused on what he called a “traditional picks and shovels capex super boom, which still feels like it’s got more to go.”
AI infrastructure has been one of the biggest drivers of global investment this year, fueling a broader market rally, even as some investors question how long the boom can last.
Nvidia, whose GPU chips are the backbone of the AI revolution, became the first company to briefly surpass $5 trillion in market capitalization amid a dizzying AI-fueled market rally that sparked talk of an AI bubble.
The build-out has set off long-term procurement efforts across the tech sector, from chip supply agreements to power commitments. Grid operators from the U.S. to the Middle East are racing to meet soaring electricity demand from new data centers. Companies, including Amazon and Meta, have budgeted tens of billions of dollars annually for AI-related investments.
S&P Global estimates data-center power demand could nearly double by 2030, mostly driven by hyperscale, enterprise and leased facilities, along with crypto-mining sites.
‘Dipping toes into credit market’
Powell also noted that leading tech firms have only begun to tap capital markets to fund the next phase of AI expansion, suggesting additional capital is on the way.
“The big companies have only just started dipping their toes into the credit markets… feels like there’s a lot more they can do there,” he said.
The “hyperscalers” are behaving as if coming second would effectively leave them out of the market, Powell said. That mindset, he added, has pushed firms to accelerate spending even at the risk of overshooting.
Much of that capital, Powell noted, is likely to flow to the companies powering the AI build-out rather than model developers, reinforcing a growing view among global investors that the most durable gains from the AI boom may lie in the hardware, energy and infrastructure ecosystems behind the technology.
“If we’re the recipients of that cash flow, I guess that’s a pretty good place to be, whether you’re making chips, whether you’re making energy all the way down to the copper wiring,” Powell noted, expecting “positive surprises driving those stocks in the year ahead.”

“Who’s watching?” Netflix asks whenever someone accesses its site. On Friday, it was probably everyone with an interest in business, markets and television.
The key characters that had people hooked were Netflix and Warner Bros. Discovery, which jointly announced that the streaming giant will acquire the latter’s film studio and streaming service, HBO Max. The equity deal value is pegged at $72 billion.
Netflix investors did not seem too jazzed about the deal, with shares dropping 2.89% on the sheer size of the transaction.
“Look, the math is going to hurt Netflix for a while. There’s no doubt,” Rich Greenfield, co-founder of LightShed Partners, told CNBC. “This is expensive,” he added.
But if one side is paying a lot, that means the other is receiving a bounty. Indeed, investors cheered the potential Warner Bros. Discovery windfall, sending the stock up 6.3% on the news.
It is not a done deal yet, and faces regulatory scrutiny. U.S. President Donald Trump said he would be involved in the decision, Reuters reported Monday, after a senior official from the Trump administration told CNBC’s Eamon Javers on Friday that they viewed the deal with “heavy scepticism.”
Despite this initial show of resistance, stranger things have happened in this administration, and the transaction might eventually go through. We may as well get ready for Netflix’s next blockbuster: “The K-Pop Demon Hunters’ Song of Ice and Fire”?

Netflix to buy Warner Bros. Discovery’s film and streaming businesses. The total equity value of the deal is $72 billion, announced the two companies Friday. But the transaction could run intoregulatory hurdles.
China’s exports grow more than expected. In U.S. dollar terms, shipments in November jumped 5.9% year on year, outstripping the 3.8% increase estimated in a Reuters poll and returning to growth from October’s 1.1% drop. But U.S.-bound exports plunged 28.6%.
A Ukraine peace deal is ‘really close.’ That’s according to Keith Kellogg, the U.S. special envoy for Ukraine, who reportedly said Saturday that there were two key outstanding issues: the future of Ukraine’s Donbas region and its Zaporizhzhia nuclear power plant.

Elon Musk has called for the European Union to be abolished after the bloc fined his social media company X 120 million euros ($140 million) for a “deceptive” blue checkmark and lack of transparency of its advertising repository.
The European Commission hit X with the ruling on Friday following a two-year investigation into the company under the Digital Services Act (DSA), which was adopted in 2022 to regulate online platforms. At the time, in a reply on X to a post from the Commission, Musk wrote, “Bulls—.”
On Saturday he stepped up his criticism of the bloc. “The EU should be abolished and sovereignty returned to individual countries, so that governments can better represent their people,” he said in a post on X.
Musk’s comments come as top U.S. government officials have also intensified their opposition to the decision.
Secretary of State Marco Rubio called the fine an “attack on all American tech platforms and the American people by foreign governments,” in a post on X on Friday.
“Today’s excessive €120M fine is the result of EU regulatory overreach targeting American innovation,” said Andrew Puzder, the U.S. ambassador to the EU, on X on Saturday.
“The Trump Administration has been clear: we oppose censorship and will challenge burdensome regulations that target US companies abroad. We expect the EU to engage in fair, open, & reciprocal trade — & nothing less.”
Last week, the Commission said breaches included “the deceptive design of its ‘blue checkmark,’ the lack of transparency of its advertising repository, and the failure to provide access to public data for researchers.”
“With the DSA’s first non-compliance decision, we are holding X responsible for undermining users’ rights and evading accountability,” said Henna Virkkunen, executive vice president for tech sovereignty, security and democracy, at the time.
X now has 60 days to inform the Commission of plans to address the issues with “deceptive” blue checkmarks. It has 90 days to submit a plan to resolve the issues with its ads repository and access to its public data for researchers.
“Failure to comply with the non-compliance decision may lead to periodic penalty payments,” the Commission said in a statement.
X.ai, the company which owns X, and the Commission have been approached for comment. oh
