Cerebras priced its IPO at $185 on May 13, opened up about 68 percent on May 14, and gave back roughly 10 percent on May 16. CBRS closed Friday May 22 at $287.16 — recovered from the dip, but still without a clean second print. [1] Seven trading days past the slide, the company has issued no statement on the customer-concentration disclosure that drove the dip, no sell-side analyst has published a note explicitly mapping the 86 percent UAE-tied revenue against the OpenAI diversification thesis, and no second hyperscaler-class customer has been announced.

The paper's Friday brief framed the file as the substitute-vs-complement argument against Nvidia held open without resolution. The S-1 disclosure is the unchanging spine: 62 percent of FY25 revenue from MBZUAI, 24 percent from G42, 77.9 percent of year-end accounts receivable from MBZUAI alone. [2] Cloud margins collapsed from 61 percent to 16 percent quarter-over-quarter; GAAP FY25 net income was $237.8 million on a non-cash G42 liability restructuring against an underlying $145.86 million operating loss.

Seven days is the natural break-glass moment for a sell-side firm to publish a customer-concentration downgrade. None has. The Seeking Alpha analyst note from May 18 with the $275 price target named the risk and stopped short of formal downgrade. [3] Tuesday's first post-Memorial-Day trading window is the next opportunity. The silence on Day seven — no statement from the company, no note from the street, no second customer named — is itself the structural artifact: the largest IPO of 2026 is also the most ambiguous, and the asymmetry between the wafer-scale narrative and the customer table is being held by absence rather than answered by either side.
