With strong ties to OpenAI, they aim to capitalize on the AI boom of 2026: California-based Cerebras Systems, a manufacturer of specialized chips for artificial intelligence, has officially initiated preparations for its initial public offering. The company plans to issue 28 million Class A shares at a price between $115 and $125 per share. This could allow the company to raise approximately $3.5 billion, valuing it at around $26.6 billion at the top end of the price range.

Cerebras had previously pursued an IPO, which was then postponed. Now the company is aiming to succeed on its second attempt.

Cerebras positions itself as a direct challenger to established GPU providers in the AI market. The company’s core product is the so-called Wafer-Scale Engine 3 (WSE-3), which the company claims is the world’s largest commercially available AI processor. The chip is 58 times larger than a leading GPU chip and is said to be up to 15 times faster than comparable GPU-based solutions for so-called inference — the processing of user requests — while consuming significantly less energy.

Prominent Investors and Ties to OpenAI

Cerebras is backed by an impressive roster of well-known investors. According to a filing with the U.S. Securities and Exchange Commission (SEC), the following investors each hold more than five percent of the company’s shares:

Alpha Wave (Rick Gerson)
Benchmark (represented by partner Eric Vishria)
Eclipse (Lior Susan)
Fidelity
Foundation Capital (represented by partner Steve Vassallo)

In addition, Cerebras counts further well-known names among its backers, including Altimeter, AMD, Coatue, Tiger Global, Valor Equity Partners, as well as Abu Dhabi Growth Fund and G42 from Abu Dhabi.

Particularly notable is the connection to OpenAI: among the angel investors are OpenAI founder and CEO Sam Altman, OpenAI co-founder and President Greg Brockman, former OpenAI Chief Scientist Ilya Sutskever, and OpenAI board member and Quora CEO Adam D’Angelo. Intel CEO Lip-Bu Tan and Sun Microsystems co-founder Andy Bechtolsheim are also among the supporters.

Valuation Jump Following Recent Funding Round

For investors who joined the Series H funding round as recently as February 2026, a successful IPO would represent a significant increase in value. That round, which raised one billion dollars, was closed at a valuation of $23 billion. At the top end of the current IPO price range, that would represent an increase of approximately 15 percent in just a few months.

Largest Tech IPO of 2026 So Far

Should the IPO succeed at the targeted price or above, it would be the largest tech IPO of 2026 to date. Market observers also see it as a signal for further pending IPOs of major technology companies such as SpaceX, and potentially OpenAI and Anthropic.

The shares are to be traded under the ticker symbol CBRS on the Nasdaq Global Select Market. Morgan Stanley, Citigroup, Barclays, and UBS Investment Bank are acting as the lead banks for the transaction. The underwriting banks also have an option to purchase up to 4.2 million additional shares within 30 days.
