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, more integrated processing chips. 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.

Cerebras Valuation
The most recent confirmed Cerebras valuation is $8.1 billion based on the Series G funding round announced in September 2025.
Private transaction data on the Hiive pre-IPO marketplace and Caplight estimates suggest the Cerebras valuation is trading around an $8.4 billion valuation as of late December 2025.
IPO Terms
The Cerebras IPO is expected in Q2 2026, according to a late-December Reuters scoop. The company plans to refile its IPO paperwork before the end of 2025 or early 2026.
I’ll update the terms below as we learn more about the upcoming terms of this deal. Monitor this webpage for updates.
- IPO Date: Q2 2026
- Cerebras Ticker Symbol: “CBRS”
- Lead Underwriters: Citi, Barclays
- Stock Exchange: Nasdaq
- Common Stock Offered: TBD
- 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.
A new filing is expected in the coming weeks.
Cerebras IPO Date and Prelude
The Cerebras IPO is expected in Q2 2026, according to a late-December Reuters scoop.
The company released its original S-1 to the public on September 30th, 2024.
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, which 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.
The author of this page will monitor and post information about Cerebras’ IPO developments through the IPO date.
S-1 Filing
Investors expect a new Cerebras S-1 filing to be released in late December 2025 or early 2026. When it is released to the public, I’ll embed a copy on this web page.
The initial Cerebras S-1 is outdated, but you can retrieve the filing from the SEC website. This filing was withdrawn and is no longer of record.

How to Invest in Cerebras Stock
Since Cerebras is a private company, it is challenging to become an equity owner today, especially for non-accredited investors.
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 access pre-IPO companies through venture capital funds.
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 or through special purpose vehicles.
Interested investors can monitor pre-IPO platforms, including Hiive, EquityZen, Augment, Nasdaq Private Markets, 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 $10,000 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 Q2 2026. Most retail investors will not receive IPO shares.
Savvy retail IPO investors can 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 has a longer track record of accessing more than 450 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 the 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.
Takeaways
Acquiring ownership in Cerebras and similar companies is challenging for most retail investors, especially non-accredited ones.
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.
Retail investors often become interested in buying startups riding extraordinary macroeconomic and technology trends (AI, supercomputing chips, LLMs) before they go public.
The Cerebras IPO is now a likely upcoming IPO in 2026, joining SpaceX and other high-profile companies that are finally moving forward.
Retail investors will likely have an excellent chance of acquiring IPO shares in the Cerebras. Follow the guidelines outlined above by having funded accounts with the best IPO brokers.
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.
IPO investing, however, is becoming more widely accessible to retail investors. Monitor the online brokers above for availability in the lead up to the IPO.
Good luck if you wish to buy Cerebras stock during the Cerebras IPO. Invest in pre-IPO and IPO companies at your own risk.
