Cerebras says it has 700 megawatts of data centre capacity under contract.

Cerebras reported record revenue of $210.8 million, said it won 2 new hyperscaler customers, and said its high-speed inference pipeline grew more than 10 times in the quarter. Caveat: GAAP operating margin was minus 106%.

Until now

Cerebras was a fast-chip niche selling systems to a few laboratories.

Now

It is contracting power at hyperscaler scale and guiding to triple.

Why it matters

Megawatts under contract is the honest unit for an inference business, because power is the one input you cannot buy late. Cerebras reports 700 of them, 2 new hyperscaler customers, and a fourth-quarter guide of $310 million to $330 million. It is also losing more at the operating line than it earns in revenue.

Established

700 megawatts of data centre capacity is now under contract.
GAAP revenue was a record $210.8 million, up 55% year over year.
Full-year core revenue guidance is $940 million to $960 million.

Not established

Which hyperscalers. Cerebras names neither of the 2 new ones.
That 2027 triples. The chief executive said he expects it.
That the 700 megawatts is energised. Contracted is not online.

The record

Cerebras Systems filed a Form 8-K with the Securities and Exchange Commission on November 12, 2026, accepted at 21:04 Universal Time, with the third quarter press release as Exhibit 99.1, followed by a Form 10-Q at 22:11. We read the press release at sec.gov. The quarter ended September 30, 2026. GAAP total revenue was a record $210.8 million, up 55% year over year. GAAP cloud and other services revenue was $141.9 million, up 265%. Core revenue, which excludes warrant amortisation, share-based pay and data centre pass-through amounts, was $230.9 million, up 70%, with core cloud revenue of $144.9 million, up 272%. GAAP gross margin was 20% and GAAP operating margin minus 106%. Core gross margin was 41% and core operating margin minus 14%. The news summary states "700 megawatts of data center capacity now under contract" and "Commercial wins with two new hyperscalers," and claims Cerebras is "first to deliver production scale heterogeneous disaggregated inference offering." Fourth quarter core revenue is guided to $310 million to $330 million, core gross margin 47% to 49%, and core operating margin minus 1% to 1%. Full-year core revenue is guided to $940 million to $960 million. Co-founder and chief executive Andrew Feldman: "That progress energizes us to do even more as we push the limits of innovation and expect to triple revenue in 2027." Chief financial officer Bob Komin said guidance was exceeded "across the board for the third quarter in a row" and that "we saw our pipeline for high-speed AI inference increase by more than 10x in the quarter." Neither hyperscaler is named. The release gives no cost for the contracted power, no backlog figure, and no date for the 700 megawatts coming online.

How it got here

Oct 12
Nvidia publishes its Vera Rubin rack designs at the Open Compute Project and sells its networking to Meta and Google. Edition 049 carded it. Inference capacity became a question of racks and power, not chips alone.
Nov 5
Google contracts 702 megawatts of carbon-capture fuel cells for a $17 billion Wyoming site. Edition 076 carded it. Megawatts became the number operators lead with.
Nov 12
Cerebras reports record revenue of $210.8 million, says 700 megawatts is under contract with 2 new hyperscalers won, and guides full-year core revenue to $940 million to $960 million.
Nov 12
Nscale discloses that a withdrawn grid connection killed $3.22 billion of Microsoft work, and Cisco doubles its hyperscaler AI expectation. One evening prices demand and power separately.

Who has to react

The 2 unnamed hyperscalers; Nvidia and AMD, whose chips Cerebras is pitched against; Oracle, taking its inference service into its cloud; the power providers behind 700 megawatts; Cerebras shareholders, holding a triple-revenue expectation for 2027; the brokers who cut AI spending forecasts this month.

What to watch

Would strengthen itCerebras reports fourth quarter core revenue at or above $310 million and names a hyperscaler customer, by March 31, 2027.
Would weaken itCerebras guides 2027 core revenue below $2 billion, or reports data centre capacity under contract below 700 megawatts, by June 30, 2027.
Would strengthen itCerebras discloses a power or data centre contract termination, impairment or renegotiation, or take-or-pay obligations larger than its annual revenue, by December 31, 2027.

CostMedium

ReversibilityModerate

PersistenceYear

Cost is medium. Contracting 700 megawatts carries real money, since power contracts are usually take-or-pay, but no figure is attached to it anywhere in the release. Commitment is high: the numbers sit in a Form 8-K and a Form 10-Q, and a chief executive saying he expects to triple revenue in 2027 is a sentence he will be read back. Reversibility is moderate. Guidance can be cut, and capacity under contract can be renegotiated or walked away from at a price. Persistence is a year: the guide stops at 2026, and the triple is a stated expectation, not a contract.

The words

Inference: Running a trained model to answer requests. It is the recurring cost of AI, where training is the one-off.
Core revenue: Cerebras' own non-GAAP measure, excluding warrant amortisation, share-based pay and data centre pass-through amounts. It is larger than its audited revenue.
Under contract: Capacity committed on paper. It is not energised, not installed, and not yet revenue.
Operating margin: Operating profit as a share of revenue. Minus 106% means the operating loss was larger than all the revenue earned.
