AI chipmaker Cerebras is trying to be the first major venture-backed tech company to go public in the U.S. since April and to capitalize on investors’ insatiable demand for Nvidia, now valued at $3.3 trillion.
While its position in artificial intelligence infrastructure represents a major tail wind, Cerebras has challenges — most notably a hefty reliance on a single Middle Eastern customer — that may prove too weighty to overcome in the company’s attempt to ride the Nvidia wave. Valued at $4 billion in 2021, Cerebras is reportedly seeking to roughly double that in its IPO.
“There’s too much hair on this deal,” David Golden, a startup investor at Revolution Ventures who led tech investment banking at JPMorgan Chase from 2000 to 2006, said in an interview this week. “This would never have gotten through our underwriting committee.”
Cerebras launched in 2016 and three years later unveiled its first processor. The company, headquartered in Sunnyvale, California, claims its current chip is faster and more efficient than Nvidia’s graphics processing unit, or GPU, for training large language models.
In 2023, Cerebras’ sales more than tripled to $78.7 million. In the first half of 2024, revenue climbed to $136.4 million, and growth appears poised to ramp up significantly, as Cerebras says in its prospectus that it’s signed agreements to sell $1.43 billion worth of systems and services, with prepayment expected before March 2025.
But the most glaring red flag in Cerebras’ filing relates to customer concentration. One company based in Abu Dhabi, United Arab Emirates, accounted for 87% of revenue in the first half of the year. The customer, G42, is backed by Microsoft, and it’s entirely responsible for the $1.43 billion purchase commitment.
Cerebras doesn’t list any other clients in its prospectus, but it does name a few on its website, including AstraZeneca, GlaxoSmithKline and the Mayo Clinic. Cerebras says in the filing that, in expanding its customer base, the company plans to “aggressively pursue opportunities in relevant sectors such as healthcare, pharmaceutical, biotechnology” and other areas “where our AI acceleration capabilities can address critical computational bottlenecks.”
In addition to its reliance on G42 for business, Cerebras counts the company as an investor, and it’s seeking clearance from the Treasury Department’s Committee on Foreign Investment in the U.S., or CFIUS, to give the Middle Eastern firm a bigger position. G42 has agreed to purchase a $335 million stake by April that, at current levels, would make it the largest owner. G42 can pick up $500 million more in Cerebras shares if it commits to spend $5 billion on the company’s computing clusters.
CFIUS has the authority to review foreign investments in U.S. companies for potential national security concerns. Cerebras said in its filing that it doesn’t believe CFIUS has “jurisdiction over G42’s purchase of our non-voting securities” but added that “there is no guarantee that CFIUS will approve” it. Reuters on Tuesday reported that Cerebras was likely to delay its initial public offering and call off its roadshow, scheduled to start next week, due to a national security review. Reuters cited people familiar with the matter.
U.S. lawmakers have expressed unease about G42’s historic ties to China, through both past investments and customer relationships. G42 said in February that it had sold its stakes in Chinese companies after Rep. Mike Gallagher, R-Wis., chairman of the Select Committee on the Chinese Communist Party, wrote a letter of concern to Commerce Secretary Gina Raimondo about what he called G42’s “extensive business relationships with Chinese military companies, state-owned entities and the PRC intelligence services.”
G42 didn’t respond to a request for comment.
Shunned by top banks
Even if it achieves CFIUS approval, Cerebras has a lot to overcome in trying to sell this deal to investors following a long stretch of suppressed valuations for smaller tech companies and a shortage of IPOs since the end of 2021.
Adding to Cerebras’ list of potential roadblocks is the fact that none of the primary tech investment banks are involved.
Goldman Sachs and Morgan Stanley have long dominated IPO underwriting in tech, with JPMorgan Chase also battling to get in the mix. They’re all absent from the Cerebras deal, and sources with knowledge of the process, who asked not to be named because the talks are private, said they stayed away in part due to the risks associated with customer concentration and foreign investment.
The deal is being led by Citigroup and Barclays, which are both large global banks but not the ones that get leadership positions on top tech IPOs.
Representatives from Citigroup, Goldman Sachs, JPMorgan and Morgan Stanley declined to comment. Barclays didn’t respond to a request for comment.
Cerebras’ auditor is BDO, which isn’t one of the so-called Big Four accounting firms. For the other three venture-backed IPOs this year, the accountants were KPMG (Reddit and Rubrik) and PwC (Astera Labs), which are two of the Big Four, along with Deloitte and Ernst & Young.
BDO declined to comment.
There’s also Cerebras CEO Andrew Feldman, who pleaded guilty in 2007 to one count of circumventing accounting controls when he was vice president of marketing at a public company called Riverstone Networks a few years earlier.
“What else could you have added to this to make it really difficult?” Revolution’s Golden said.
A Cerebras spokesperson declined to comment for this story.
The major Wall Street banks, for their part, are finding other ways to play in the burgeoning AI infrastructure market. Last week, Goldman Sachs, JPMorgan and Morgan Stanley were among a roster of banks that participated in issuing a $4 billion revolving line of credit to OpenAI. And on Friday, Nvidia GPU provider CoreWeave announced the close of a $650 million credit facility that was led by the top three tech banks.

For Cerebras, there’s still a path to an IPO, given the sheer excitement around AI chips and the dearth of investable opportunities in the market.
Also, Nvidia is trading near a record. Mizuho Securities estimates that Nvidia controls 95% of the market for AI training and inference chips used for models like OpenAI’s GPT-4. Venture capitalist Peter Thiel said at the All-In Summit last month that Nvidia is the only company in the space that’s making money.
“Nvidia is making over 100% of the profits,” Thiel said in an on-stage interview at the event in Los Angeles. “Everybody else is collectively losing money.”
Cerebras is still in the money-losing column, reporting a second-quarter net loss of almost $51 million. However, excluding stock-based compensation, the company is close to breakeven on an operating basis.
Retail investor Jim Fitch, a retired homebuilder in Florida, is among those excited about the opportunity to get in early. Fitch, who said he sold out of his Nvidia stock years ago, told CNBC that the benefits outweigh the risks. He noted that Feldman, Cerebras’ co-founder and CEO, sold his prior company, SeaMicro, to Nvidia rival Advanced Micro Devices for more than $300 million over a decade ago.
Fitch is drawn to the promise of Cerebras’ technology, particularly its WSE-3 chip, which the company calls “the fastest AI processor on Earth,” packed with 4 trillion transistors.
TikTok’s grip on the short-form video market is tightening, and the world’s biggest tech platforms are racing to catch up.
Since launching globally in 2016, ByteDance-owned TikTok has amassed over 1.12 billion monthly active users worldwide, according to Backlinko. American users spend an average of 108 minutes per day on the app, according to Apptoptia.
TikTok’s success has reshaped the social media landscape, forcing competitors like Meta and Google to pivot their strategies around short-form video. But so far, experts say that none have matched TikTok’s algorithmic precision.
“It is the center of the internet for young people,” said Jasmine Enberg, vice president and principal analyst at Emarketer. “It’s where they go for entertainment, news, trends, even shopping. TikTok sets the tone for everyone else.”
Platforms like Meta‘s Instagram Reels and Google’s YouTube Shorts have expanded aggressively, launching new features, creator tools and even considering separate apps just to compete. Microsoft-owned LinkedIn, traditionally a professional networking site, is the latest to experiment with TikTok-style feeds. But with TikTok continuing to evolve, adding features like e-commerce integrations and longer videos, the question remains whether rivals can keep up.
“I’m scrolling every single day. I doom scroll all the time,” said TikTok content creator Alyssa McKay.
But there may a dark side to this growth.
As short-form content consumption soars, experts warn about shrinking attention spans and rising mental-health concerns, particularly among younger users. Researchers like Dr. Yann Poncin, associate professor at the Child Study Center at Yale University, point to disrupted sleep patterns and increased anxiety levels tied to endless scrolling habits.
“Infinite scrolling and short-form video are designed to capture your attention in short bursts,” Dr. Poncin said. “In the past, entertainment was about taking you on a journey through a show or story. Now, it’s about locking you in for just a few seconds, just enough to feed you the next thing the algorithm knows you’ll like.”
Despite sky-high engagement, monetizing short videos remains an uphill battle. Unlike long-form YouTube content, where ads can be inserted throughout, short clips offer limited space for advertisers. Creators, too, are feeling the squeeze.
“It’s never been easier to go viral,” said Enberg. “But it’s never been harder to turn that virality into a sustainable business.”
Last year, TikTok generated an estimated $23.6 billion in ad revenues, according to Oberlo, but even with this growth, many creators still make just a few dollars per million views. YouTube Shorts pays roughly four cents per 1,000 views, which is less than its long-form counterpart. Meanwhile, Instagram has leaned into brand partnerships and emerging tools like “Trial Reels,” which allow creators to experiment with content by initially sharing videos only with non-followers, giving them a low-risk way to test new formats or ideas before deciding whether to share with their full audience. But Meta told CNBC that monetizing Reels remains a work in progress.
While lawmakers scrutinize TikTok’s Chinese ownership and explore potential bans, competitors see a window of opportunity. Meta and YouTube are poised to capture up to 50% of reallocated ad dollars if TikTok faces restrictions in the U.S., according to eMarketer.

Elon Musk‘s xAI Holdings is in discussions with investors to raise about $20 billion, Bloomberg News reported Friday, citing people familiar with the matter.
The funding would value the company at over $120 billion, according to the report.
Musk was looking to assign “proper value” to xAI, sources told CNBC’s David Faber earlier this month. The remarks were made during a call with xAI investors, sources familiar with the matter told Faber. The Tesla CEO at that time didn’t explicitly mention any upcoming funding round, but the sources suggested xAI was preparing for a substantial capital raise in the near future.
The funding amount could be more than $20 billion as the exact figure had not been decided, the Bloomberg report added.
Artificial intelligence startup xAI didn’t immediately respond to a CNBC request for comment outside of U.S. business hours.
The AI firm last month acquired X in an all-stock deal that valued xAI at $80 billion and the social media platform at $33 billion.
“xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent,” Musk said on X, announcing the deal. “This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.”

Alphabet‘s stock gained 3% Friday after signaling strong growth in its search and advertising businesses amid a competitive artificial intelligence environment and uncertain macro backdrop.
“GOOGL‘s pace of GenAI product roll-out is accelerating with multiple encouraging signals,” wrote Morgan Stanley‘s Brian Nowak. “Macro uncertainty still exists but we remain [overweight] given GOOGL’s still strong relative position and improving pace of GenAI enabled product roll-out.”
The search giant posted earnings of $2.81 per share on $90.23 billion in revenues. That topped the $89.12 billion in sales and $2.01 in EPS expected by LSEG analysts. Revenues grew 12% year-over-year and ahead of the 10% anticipated by Wall Street.
Net income rose 46% to $34.54 billion, or $2.81 per share. That’s up from $23.66 billion, or $1.89 per share, in the year-ago period. Alphabet said the figure included $8 billion in unrealized gains on its nonmarketable equity securities connected to its investment in a private company.
Adjusted earnings, excluding that gain, were $2.27 per share, according to LSEG, and topped analyst expectations.

Alphabet shares have pulled back about 16% this year as it battles volatility spurred by mounting trade war fears and worries that President Donald Trump‘s tariffs could crush the global economy. That would make it more difficult for Alphabet to potentially acquire infrastructure for data centers powering AI models as it faces off against competitors such as OpenAI and Anthropic to develop largely language models.
During Thursday’s call with investors, Alphabet suggested that it’s too soon to tally the total impact of tariffs. However, Google’s business chief Philipp Schindler said that ending the de minimis trade exemption in May, which created a loophole benefitting many Chinese e-commerce retailers, could create a “slight headwind” for the company’s ads business, specifically in the Asia-Pacific region. The loophole allows shipments under $800 to come into the U.S. duty-free.
Despite this backdrop, Alphabet showed steady growth in its advertising and search business, reporting $66.89 billion in revenues for its advertising unit. That reflected 8.5% growth from the year-ago period. The company reported $8.93 billion in advertising revenue for its YouTube business, shy of an $8.97 billion estimate from StreetAccount.
Alphabet’s “Search and other” unit rose 9.8% to $50.7 billion, up from $46.16 billion last year. The company said that its AI Overviews tool used in its Google search results page has accumulated 1.5 billion monthly users from a billion in October.
Bank of America analyst Justin Post said that Wall Street is underestimating the upside potential and “monetization ramp” from this tool and cloud demand fueled by AI.
“The strong 1Q search performance, along with constructive comments on Gemini [large language model] performance and [AI Overviews] adoption could help alleviate some investor concerns on AI competition,” Post wrote in a note.
