About Cerebras

Cerebras Systems is a Sunnyvale, California-based artificial intelligence (AI) company that builds hardware platforms designed to train massive AI models. Its supercomputing platform is available in the cloud or on-premises and enables users to: 

Train and fine-tune production AI models quickly and easily. Use your data and own your model. Train in the cloud or on-premises, pain-free.

Nvidia, Groq, and CoreWeave get a lot of attention for AI computer processing. Think of Cerebras as a startup competitor that makes larger, all-encompassing processing chips with a more integrated design. It also builds the hardware and software stack for an integrated AI computing platform. 

The Wafer Scale Engine (WSE) has 850,000 cores and 2.6 trillion transistors and powers its CS-2 AI supercomputer box. WSE is the largest computer chip ever deployed. 

Cerebras clusters 64 CS-2 systems to create the largest AI supercomputer, the Condor Galaxy. It plans for nine Condor Galaxy deployments, enabling the Cerebras Cloud service. 

The company attracts mature companies and scientific research labs that need extraordinary computing power to advance their AI training models. It also boasts several high-profile AI startups as customers who can scale quickly on the platform. 

In August 2024, Cerebras launched the world’s fastest inference, offering faster speeds and lower costs than GPUs. 

Here’s an introduction video showing off the hardware stack in one of its facilities.

IPO Terms

The Cerebras IPO was withdrawn on October 3rd, 2025. The company says it still aspires to IPO, but we must now question its sincerity. 

The following terms came from the September 30th, 2024 S-1. But are now outdated and will likely not be the terms of the eventual IPO. 

Monitor this webpage for updates. 

• IPO Date: DELAYED
• Common Stock Offered: TBD
• Cerebras Ticker Symbol: “CBRS”
• Lead Underwriters: Citi, Barclays
• Stock Exchange: Nasdaq
• Estimated Valuation: $7-$8 Billion
• Estimated Raise: $750 million to $1 Billion
• IPO roadshow (TBD)
• Pricing Date: TBD
• IPO Price: TBD
• Opening Trade: TBD

The company’s initial S-1 filing became public on 09/30/2024. However, an October 8th Reuters report indicated the IPO is postponed due to a Committee on Foreign Investment in the United States (CFIUS) review. 

The company announced CFIUS clearance on March 31st, 2025, and is OK to move forward if it chooses to do so. But it raised $1.1 billion in a Series G round that closed in September 2025, providing sufficient capital for the time being.

Cerebras IPO Date

The Cerebras IPO date is unknown. As of October 3rd, 2025, the deal is off, having withdrawn its IPO filing because it became “stale”. 

The company released its S-1 to the public on September 30th, 2024. IPOs usually happen three to six weeks after the filing is released to the public.

We were expecting a late-October IPO until an October 8th Reuters report indicated the IPO is likely to be postponed due to a Committee on Foreign Investment in the United States (CFIUS) review. 

The CFIUS review stems from the S-1 filing, which disclosed that UAE-based G42, who is both a Cerebras investor and customer, accounted for 83% of Cerebras’s 2023 revenue and 97% of hardware sold thus far in 2024. 

Cerebras has received clearance from the CFIUS review, making it possible to move forward.

But it chose to raise private funds in early 2025. It closed the funding round on September 30th, and subsequently withdrew its IPO filing. 

Cerebras has hired Citigroup to lead its IPO, but the timing of such a deal is now uncertain. 

Private AI fundraising is booming as chatbot companies such as Anthropic, Sam Altman’s OpenAI, and a competitor led by former DeepMind founders, Inflection AI, have all raised significant funds. 

AI companies have yet to venture into public offerings, but we anticipate a wave of AI IPOs in the next one to five years. Cerebras may be a first-mover. 

CEO Andrew Feldman’s previous company, SeaMicro, was acquired by AMD in 2012. But the January 2024 Bloomberg shows the company is serious about a public future. 

This page will monitor and post information about Cerebras IPO developments. 

S-1 Filing

Read the Cerebras S-1 filing September 30th, 2024 below. This filing was withdrawn and is no longer of record. But I am keeping it here for reference. 

You can also read the S-1 on the SEC website and monitor for amended filings. 

Valuation

The last confirmed Cerebras valuation is $8.1 billion based on the Series G private funding round that completed in September 2025.

The now-postponed Cerebras IPO aimed value the company at $7-$8 billion according to a Bloomberg report. 

Startups tend to raise private funds to last two years, suggesting Cerebras may be due for another private funding round or an IPO unless it is cash flow positive. 

Private transaction data on the Hiive pre-IPO marketplace and other sources suggests the Cerebras valuation is trading around a $5 billion valuation as of Q3 2025, which will likely increase after the Series G completion. 

Stock Price

A public Cerebras stock price is not available. We won’t get a better sense of the share price until the IPO price is floated to investors about a week before the public debut. 

The Series G funding round that closed in September 2025 was priced at around $56 per share. 

Private transactions took place at around $36 per share on the Hiive marketplace in Q3 2025.

How to Invest in Cerebras Stock

Since Cerebras is a private company, it is challenging to become an equity owner today.

However, you can increase your chances of early equity ownership or obtain shares in the IPO by taking the actions outlined below.

Accredited investors will have an easier time via pre-IPO investing platforms. Non-accredited investors can look to venture capital funds for access to pre-IPO companies. 

1. Access via pre-IPO investing platforms

The author has seen multiple opportunities to invest in Cerebras stock on pre-IPO investing platforms. Only accredited investors may buy stock directly. 

However, these opportunities will likely go away soon since it has filed for an IPO. 

Interested investors can monitor pre-IPO platforms, including Hiive, EquityZen, and Forge Global for current availability.

Shares may become available through sales by early investors or employees before the IPO.

Minimum investment amounts range from $1,000 to $50,000 or more on various platforms. Investors must meet the SEC accreditation standard to be eligible for direct investment. 

Signing up for online access to pre-IPO data, deal alerts, and expressing interest in currently unavailable startups is free.

Non-accredited retail investors can invest in leading pre-IPO AI, fintech, and defense startups via Fundrise Venture (review). All U.S.-based investors 18+ are eligible to invest. $10 minimum investment.

However, investors cannot select individual pre-IPO companies, and Cerebras stock is not a current holding.

2. Participate in the Cerebras IPO through a broker

The Cerebras IPO could happen as soon as the end of October. Most retail investors will not receive IPO shares. 

But, savvy retail IPO investors may find opportunities to invest during the IPO when it arrives. IPO access has become increasingly accessible to retail investors in the past few years. 

The following online brokers give customers free access to IPOs with low minimum deposits:

• TradeStation 
• Robinhood
• Webull

Exclusive access to highly sought-after IPOs may be limited based on the type of brokerage accounts you hold and which brokerages have secured exclusive rights.

TradeStation has a longer track record of accessing more than 360 IPOs and secondary offerings via its partnership with Click Markets

But Robinhood has the advantage of Silicon Valley networks and a history of getting allocations for high-profile IPOs.

Read the S-1 filings to find mentions of these online brokers to find opportunities. 

Check out this list of best brokers for IPO investing to learn more about IPO access for retail investors.

3. Buy Cerebras stock after the IPO

Most investors will not acquire pre-IPO shares or receive an allocation during the IPO. They will need to wait until an IPO or acquisition to own a small slice of Cerebras. 

Investing after the IPO has advantages. The market-based pricing and regulated filings reduce investor risk. Furthermore, public numbers make it easier for retail investors to perform due diligence before investing. 

Avoid chasing over-inflated share prices immediately after the IPO. Stock price declines after IPOs can be excellent entry points.

Be selective and patient. The most disruptive companies are likely to experience higher valuations a decade from now.

Conclusion

Retail investors often become interested in buying startups riding extraordinary macroeconomic and technology trends (AI, supercomputing chips, LLMs) before they go public. 

However, acquiring ownership in Cerebras and similar companies is challenging for retail investors, especially non-accredited ones, due to regulations. 

Cerebras is unique in that pre-IPO shares have been available leading up to the IPO. Investors with conviction in the company may find ways to profit from early access headed into the IPO. 

Unfortunately, the Cerebras IPO is likely to be postponed, which could stall this deal and the next wave of IPO. Investors had high hopes that Cerebras would kick off a wave of AI IPOs, but the S-1 filing has shown that risks are real for young companies. 

Pre-IPO investing platforms have opened more opportunities for retail investors. However, venture capital investing is still mostly reserved for super-wealthy and accredited investors. And it’s too late now that the IPO is near. 

Investors will likely hit roadblocks trying to obtain IPO shares. Open accounts with the IPO brokers above and monitor the offerings in your account. 

Good luck if you wish to buy Cerebras stock during the Cerebras IPO. Invest in pre-IPO and IPO companies at your own risk.
