AI Chipmaker Cerebras Withdraws U.S. IPO Filing After $1.1 Billion Fundraising Round

Cerebras Systems, the California-based AI chip startup seen as one of the most promising challengers to Nvidia, has withdrawn its planned U.S. initial public offering (IPO), according to a regulatory filing on Friday. The decision takes effect immediately and comes just days after the company closed a massive $1.1 billion funding round.

The move surprised some investors given that U.S. IPO activity has recently rebounded sharply, buoyed by surging enthusiasm for AI-related stocks. Recent debuts, such as Fermi’s data center REIT listing, have drawn strong investor demand, reversing a slump caused by trade-policy and market uncertainty earlier in the year.

Analysts said the withdrawal likely reflects strategic timing rather than weak market sentiment. “Given that Cerebras just very recently completed a sizeable fund raise, it is of no surprise that they are holding off to pursue the IPO at this time,” said Josef Schuster, CEO of IPO research firm IPOX.

Cerebras’ latest financing round—led by Fidelity Management & Research and Atreides Management—valued the company at $8.1 billion and included participation from Tiger Global, Valor Equity Partners, and 1789 Capital, a fund partially linked to Donald Trump Jr.

Despite withdrawing the IPO filing, CEO Andrew Feldman emphasized that the company still intends to go public eventually. “We’re continuing to execute on our roadmap,” he said earlier in the week, noting that Cerebras’ focus remains on scaling production and commercialization of its high-performance AI chips designed to accelerate the training of large models.

The company had initially filed for a Nasdaq listing last year, but the process was delayed by a U.S. national security review of a $335 million investment from G42, an Abu Dhabi-based cloud and AI firm. That review reportedly examined potential concerns about foreign influence and technology transfer.

Industry observers view Cerebras’ decision as a pause, not a retreat. “This is more a company-specific strategic decision and does not tell us anything about the state of U.S. IPO sentiment, which we view as exceptionally strong,” Schuster added.

Founded in Sunnyvale, California, Cerebras Systems specializes in ultra-large AI processors and computing systems, including its flagship Wafer Scale Engine (WSE), a chip designed to massively outperform traditional GPUs in AI workloads. The company has become a key player in the rapidly expanding AI hardware ecosystem—one now defined by fierce competition, colossal valuations, and geopolitical scrutiny.

Elon Musk’s X Now Valued 80% Less Than Purchase Price, According to Fidelity

The social media platform formerly known as Twitter, now X, has seen its value plunge nearly 80% since Elon Musk acquired it in October 2022. This staggering drop in valuation comes from estimates provided by Fidelity, a major investment firm that owns shares in X through its Blue Chip Growth Fund.

When Musk took Twitter private for $44 billion, it was a highly publicized acquisition. However, as of August 2024, Fidelity estimates that its shares in X are worth only $4.2 million, suggesting that the overall valuation of the company now stands at $9.4 billion—a far cry from the original purchase price. This represents a 24% drop from Fidelity’s own estimate in July and a 79% decline from its original valuation at the time of Musk’s purchase.

Declining Ad Revenue and Brand Safety Concerns

Fidelity’s assessment aligns with analysts’ concerns over X’s shrinking ad revenue, an issue compounded by the platform’s failure to publicly release financial metrics. Advertising has been a significant pain point for X since Musk’s acquisition, particularly with advertisers expressing discomfort over extreme content appearing on the platform. A Kantar global survey recently revealed that 26% of marketers plan to reduce ad spending on X in the coming year, with concerns over brand safety. Only 4% of advertisers believed their ads were safe from appearing near problematic content on X, compared to 39% on Google.

Musk’s public behavior has also contributed to advertiser unease. In November, he faced backlash after endorsing an antisemitic conspiracy theory. While he later apologized, he infamously told advertisers who were halting spending on X: “Go f**k yourself.”

Despite these setbacks, X remains a key player in social media with 570 million monthly active users in the second quarter of 2024, reflecting a 6% growth year-over-year. However, Similarweb data indicated declining engagement, particularly in the U.S., where X’s monthly active users on iOS and Android dropped 11% from the previous year and 20% since Musk’s acquisition.

Fidelity’s Estimate vs. Other Projections

While Fidelity’s valuation implies significant losses, not all experts agree with the extent of the decline. Gene Munster, managing partner at Deepwater Asset Management, argues that Fidelity is “overly aggressive” in its devaluation, believing the firm is simply cleaning house on its investment. Munster sees a longer-term potential in X’s vast data, particularly as a critical source of training material for Grok, an AI chatbot developed by xAI, Musk’s AI startup.

Dan Ives, an analyst at Wedbush Securities, suggested that Musk may have initially overpaid for Twitter, estimating its worth closer to $30 billion at the time of purchase and $15 billion today. However, Munster maintains optimism, noting that X’s value lies in the unique real-time data it provides, which is becoming increasingly valuable in the AI landscape. He added that Musk’s acquisition of Twitter might be a case of being “better lucky than smart,” given the rapid developments in AI.
