Cerebras IPO Pricing Review: $185 a Share in the 424B4 Prospectus

Key takeaways

• Cerebras Systems set its IPO pricing at $185.00 per Class A share, selling 30 million shares for gross proceeds of $5.55 billion, according to its final 424B4 prospectus filed May 14, 2026.
• Underwriters received $4.3475 per share, about 2.35% of the offering price, leaving roughly $5.41 billion for the company before expenses.
• The stock was set to trade on the Nasdaq Global Select Market under the ticker CBRS, with closing expected May 15.
• Class B holders retain about 99.2% of the voting power after the offering.
• The prospectus shows revenue of $510.0 million for 2025, up from $290.3 million in 2024, and a swing to GAAP net income.

The IPO pricing at a glance

Cerebras, the AI chip and systems company, dated its final prospectus May 13, 2026, and filed it with the SEC the following day. The 424B4 prospectus is the document that locks in the terms after the book is built, and in this case it describes one of the largest technology IPOs of the year by dollars raised.

Item	Figure
Shares offered (Class A)	30,000,000
Price per share	$185.00
Gross proceeds	$5.55 billion
Underwriting discount	$4.3475/share ($130.425 million)
Proceeds to company, before expenses	about $5.408 billion
Underwriters’ option	4,500,000 shares
Class B shares after offering	about 185.11 million

All 30 million shares were sold by the company, so the full net amount went to Cerebras rather than to existing holders. If underwriters exercised their option in full, Class A shares outstanding would rise to 34.5 million.

What the numbers say about IPO valuation

The prospectus lists about 30 million Class A shares and about 185.11 million Class B shares outstanding after the offering, before any option exercise. Multiplying the roughly 215 million combined shares by the $185 offering price implies an equity value in the neighborhood of $40 billion at the IPO price. That figure is our arithmetic from the share counts in the filing, not a number the company states, and it excludes options and other equity awards.

Against 2025 revenue of $510.0 million, that implied value is a large multiple of sales, which tells readers how much growth the offering price anticipates. The revenue trend supports the growth narrative: sales rose about 76% from 2024 to 2025 based on the reported figures.

Profitability: read the fine print

The prospectus reports GAAP net income of $237.8 million for 2025, compared with a net loss of $481.6 million in 2024. On its non-GAAP measure, however, Cerebras reported a net loss of $75.7 million in 2025, wider than the $21.8 million non-GAAP loss in 2024.

The gap between the two measures means the 2025 GAAP profit was shaped by items the company itself adjusts out when presenting its preferred performance metric. Readers comparing Cerebras with other AI hardware names should look at both figures rather than relying on the headline net income.

Governance and control

The dual-class structure is the other key feature. With Class B holders controlling about 99.2% of voting power, public Class A investors bought economic exposure with very limited say in director elections or major corporate decisions. That level of concentration is high even by the standards of founder-led technology IPOs.

The underwriting syndicate

Morgan Stanley, Citigroup, Barclays and UBS Investment Bank are named among the lead underwriters. The 2.35% gross spread is low by historical IPO standards, which is typical for very large offerings where banks compete on fee for a marquee mandate.

What to watch

The first financial reports as a public company will show whether revenue growth continues at the pace described in the prospectus and how the GAAP and non-GAAP results reconcile. Watch whether the underwriters exercise their 4.5 million share option, when pre-IPO holders become free to sell, and any change in how the dual-class voting structure is applied.
