Why is Cerebras Systems stock surging today?

Cerebras Systems' stock skyrocketed 19.2% in pre-market trading today, reaching $116.54 per share. The surge was driven by an impressive third-quarter earnings report that surpassed expectations in nearly every key metric. The company reported $231 million in core revenue, a 70% year-over-year increase, which exceeded Wall Street's $215 million forecast. Cerebras also achieved its first-ever positive non-GAAP net income of about $30 million.

Management boldly raised full-year 2026 core revenue guidance to $940 million–$960 million, surpassing initial expectations. The company also forecasted Q4 core revenue of $310 million–$330 million, roughly 18% higher than consensus estimates. A significant development was the announcement of a cloud inference deal with Microsoft, signed in October, which completes a trio of major hyperscaler partnerships alongside existing agreements with Amazon Web Services and Oracle.

Cloud revenue alone surged 272% year-over-year to nearly $145 million on a non-GAAP basis. This strong performance was bolstered by Morgan Stanley's decision to maintain its Overweight rating and raise its price target to $178 per share. The analyst cited an upward revision in the company's full-year revenue outlook, driven by increased hardware shipments and expected expansion of gross margins as older, lower-priced hardware contracts phase out.

Despite broader market caution, as indicated by U.S. equity futures under pressure due to hotter-than-expected October CPI data, the pre-market surge of Cerebras's stock was particularly noteworthy. This performance stood out as a stark contrast to the more subdued reaction from technology and semiconductor peers. While the company acknowledged delivery delays on its OpenAI contract tied to data center construction timelines, Morgan Stanley deemed this risk as not altering their positive outlook, given Cerebras' expanding capacity pipeline.
