Cerebras Q2 2026: revenue grew 74%, and gross profit fell 20%

Cerebras builds wafer-scale chips and sells the inference they run. It came public in May 2026 in an IPO raising $6.4 billion gross, and this is only its second quarter as a public company.

The release leads with core revenue “more than doubled to $210 million”. That is a real number and the business behind it is growing fast. But the same filing contains a second set of books, and the two tell different stories about the same three months.

Two accounts of one quarter

Q2 2026	GAAP	Core (non-GAAP)
Total revenue	$180.1M	$209.9M
Growth year over year	+74%	+103%
Gross margin	14%	41%
Operating margin	(265)%	(16)%

A 29-point spread on the growth rate and a 27-point spread on gross margin, in the same quarter. The company discloses exactly how it gets from one to the other, and the reconciliation is the most useful table in the release.

Did Cerebras beat its own guidance in Q2 2026?

Yes, on every core metric it guided. Core revenue of $209.9 million came in above the approximately $194.0 million Cerebras guided to in its June 23, 2026 8-K; core gross margin of 41% was above the top of the 36–38% range; and the core operating margin of (16)% was better than the guided (30)% to (32)%. The company guides only core (non-GAAP) figures, so GAAP revenue of $180.1 million, up 74% year over year, and GAAP gross margin of 14% have no guidance to measure against; core revenue rose 103%. The full-year 2026 outlook was raised on all three lines: core revenue to $880–890 million from $855–865 million, core gross margin to 41–43% from 38–41%, and core operating margin to (19)% to (17)% from (28)% to (32)%.

The bridge is $44.3 million of customer warrants

Q2 2026 reconciliation	Total	Hardware	Cloud
GAAP revenue	$180.1M	$54.1M	$126.0M
Less: pass-through revenue	$(14.5)M	—	$(14.5)M
Add: amortisation of customer warrant assets	+$44.3M	+$28.0M	+$16.2M
Core revenue	$209.9M	$82.1M	$127.7M

In the same quarter a year ago, neither adjustment existed: GAAP revenue and core revenue were both $103.3 million.

A customer warrant is the right for a customer to buy Cerebras stock on agreed terms — equity handed to the buyer as part of winning the business. Under GAAP the value of that equity is amortised against revenue, because economically it is a discount: the customer pays less than the invoice says once you count what it received back in shares. Core revenue adds it back.

Two things follow, and both matter.

It is 24.6% of GAAP revenue. Not a rounding adjustment — a quarter of the top line.

It reverses the direction of the hardware business.

Hardware revenue	Q2 2026	Q2 2025	Change
GAAP	$54.1M	$70.3M	−23.0%
Core	$82.1M	$70.3M	+16.8%

The same business, the same three months: down 23% on one basis, up 17% on the other, and the entire difference is $28.0 million of warrants issued to hardware customers. Whether Cerebras’s systems business grew or shrank this quarter depends on whether you count the stock it gave away as revenue.

Neither answer is dishonest. GAAP says the equity is a cost of the sale; the company says it is non-cash and unrelated to how the business is performing. But a reader deciding what the company is worth should know that the headline growth rate rests on that judgement, and that it did not have to be made at all a year ago.

The balance sheet shows how fast this is scaling: customer warrants carried as assets were $1.128 billion at 30 June — $167.8 million current plus $960.6 million non-current — against $152.4 million at the end of 2025. That is more than six times the quarter’s entire GAAP revenue, sitting on the balance sheet, to be amortised against future revenue.

Under GAAP, gross profit went backwards

	Q2 2026	Q2 2025	Change
Revenue	$180.1M	$103.3M	+74.3%
Cost of revenue	$154.6M	$71.2M	+117.0%
Gross profit	$25.6M	$32.1M	−20.4%
Gross margin	14.2%	31.1%	−17 pts

Cost of revenue grew at more than one and a half times the rate of revenue. On $76.8 million of extra revenue the company kept negative $6.5 million of extra gross profit.

The cloud line explains most of it. Cloud revenue rose 281% to $126.0 million; cloud cost of revenue rose 313% to $101.4 million. So cloud gross margin fell from 25.6% to 19.5% even as the business quadrupled. Zacks’s preview before the print flagged the mechanism: Cerebras has been “temporarily renting back systems from an existing customer” to meet inference demand until its own data-centre capacity is ready — capacity it is buying, with 600 MW now under contract.

That is a solvable problem and management has said so; it is also why the company guided Q2 core gross margin to 36–38% and then delivered 41%, which is a genuine beat against its own guidance. The GAAP picture simply has further to travel.

The cost base after an IPO

Q2 2026	Amount	A year ago
Research and development	$320.2M	$60.8M
Sales and marketing	$87.0M	$18.2M
General and administrative	$95.7M	$10.3M
Total operating expenses	$502.8M	$89.3M
Loss from operations	$(477.2)M	$(57.2)M

Operating expenses were 2.8 times revenue. R&D alone rose 427% year over year and was nearly twice total revenue.

Most of that step is almost certainly the accounting consequence of listing — equity awards that vest on an IPO land in the quarter the IPO happens, and Cerebras listed in May. The company’s core operating margin of (16)%, against (265)% on GAAP, is the version with stock compensation removed. Both numbers are true; the GAAP one is what the accounts say happened.

The year-over-year comparison at the bottom of the income statement should be read with the same care. Cerebras reports a net loss of $450.5 million against net income of $309.5 million a year earlier — but that prior-year profit came from $368.4 million of other income, not from operations. On the operating line the comparison is $(57.2) million then, $(477.2) million now.

What is genuinely strong here

Set the accounting aside and the demand signals in this release are extraordinary.

Item	Company figure
Remaining performance obligations	$25.4 billion
Data-centre capacity under contract	600 MW
Manufacturing capacity	to scale more than 10x in 2026
Liquidity	$8.6 billion of cash, equivalents, restricted cash and short-term investments, plus $850 million of debt capacity
OpenAI	launch partner for the GPT-5.6 Sol frontier model
Partners	AMD and AWS on disaggregated inference; CrowdStrike on inline security
Named customers	Block, Figma, AlphaSense, GSK
2027	management “plan to more than triple revenue”

Remaining performance obligations of $25.4 billion against a full-year 2026 core revenue guide of $880–890 million is roughly 29 years of revenue already contracted. Even discounted heavily for timing and for the customer concentration that a single $20 billion-plus OpenAI agreement implies, that is not a demand problem.

And the balance sheet can fund the build: $8.6 billion of liquidity against a quarter in which cash and restricted cash rose $6.5 billion on the IPO.

The guidance, and the arithmetic inside it

Outlook (core, non-GAAP)	Company figure
Q3 2026 core revenue	$214–216 million
Q3 2026 core gross margin	38%–40%
Q3 2026 core operating margin	(25)% to (23)%
FY2026 core revenue	$880–890 million (raised)
FY2026 core gross margin	41%–43% (raised)
FY2026 core operating margin	(19)% to (17)% (raised)

Two things are worth working out.

The margin path is not a straight line. Core gross margin was 46.5% in Q1 (the reconciliation table of the Q1 release; its highlights round it to 47%) and 41% in Q2, and Q3 is guided to 38–40% — lower again. Yet the full year is guided to 41–43%. On our arithmetic, with roughly $401 million of core revenue booked in the first half at a blended margin of about 44%, hitting the full-year range requires the fourth quarter to be the strongest gross-margin quarter of the year — meaningfully above the third. That is achievable if the rented-capacity drag rolls off as owned data centres come online, which is exactly what management says will happen. It is also the single most checkable commitment in the release.

The revenue path is back-loaded too. First-half core revenue of about $401 million against a full-year guide of $880–890 million leaves roughly $479–489 million for the second half. Take out the Q3 guide of $214–216 million and the fourth quarter is implied at roughly $263–275 million — a 22% to 28% step up on Q3 in a single quarter.

The bear case, stated fairly

1. GAAP gross profit fell 20% on 74% revenue growth, and GAAP gross margin fell from 31% to 14%.
2. The headline growth rate depends on a non-GAAP judgement. $44.3 million of customer-warrant amortisation — 24.6% of GAAP revenue — is added back, and the adjustment did not exist a year ago.
3. Hardware revenue fell 23% under GAAP. It rose 17% only after $28.0 million of warrants are added back.
4. $1.128 billion of customer warrants sits on the balance sheet, up more than sixfold in six months, to be amortised against revenue in future periods.
5. Cloud margins compressed while cloud revenue quadrupled, from 25.6% to 19.5%, because capacity is being rented rather than owned.
6. Operating expenses were 2.8x revenue and the operating loss was $477.2 million.
7. Q3 core gross margin is guided below Q2, and the full-year range requires Q4 to be the best margin quarter of the year.
8. The prior-year “profit” was other income, so the year-over-year swing at the net line flatters the deterioration in operations.

The bull case is the growth. Core revenue more than doubled and beat the company’s own guide; core gross margin of 41% beat a 36–38% guide by three points; cloud revenue nearly quadrupled; $25.4 billion of contracted work is on the books against $880–890 million of guided revenue this year; 600 MW of capacity is contracted and manufacturing is set to scale more than tenfold; OpenAI, AWS, AMD and CrowdStrike are named partners; and $8.6 billion of liquidity means the build-out does not depend on markets staying friendly.

What to check at the Q3 report

• GAAP gross margin against 14%. Core margin tells you the trajectory management is steering to; GAAP tells you what the accounts recorded. The gap between them is the thing to watch close.
• The customer-warrant add-back against $44.3 million, and the $1.128 billion balance. If the add-back keeps growing faster than revenue, the two sets of books keep diverging.
• GAAP hardware revenue against $54.1 million. This is the systems business without the equity sweetener.
• Cloud gross margin against 19.5%, and how much capacity has moved from rented to owned.
• Core gross margin against the guided 38–40%, and whether the full-year 41–43% still stands after it.
• Q4’s implied ~$263–275 million of core revenue — the step-up the annual guide requires.
• Operating expenses against $502.8 million, to see how much of this quarter was one-off IPO vesting and how much is the new run rate.

The read

Cerebras has demand that almost nobody in this industry can match — $25.4 billion of contracted work, OpenAI as a launch partner, 600 MW under contract — and a balance sheet with $8.6 billion on it. Nothing here suggests the market is the constraint.

What the filing does show is that the economics have not yet caught up with the demand, and that the company’s preferred measure is doing real work to bridge the gap. Under GAAP this was a quarter in which revenue grew 74% and gross profit shrank, in which the hardware business declined, and in which the cost of serving cloud customers grew faster than the revenue from them.

For anyone holding CBRS, the discipline is to read both columns and to know which one you are being shown. GAAP gross margin tells you what the business earned. The warrant add-back tells you how much of the growth was paid for in stock. Cloud gross margin tells you whether owning capacity instead of renting it is working. The core numbers are not wrong — they are just the version with the hardest parts removed.

These were read directly from the filing on SEC EDGAR, which is linked above. The quotations from Andrew Feldman and Bob Komin are from the same document.

Not company figures, and attributed accordingly: the consensus estimates of roughly $194.16 million of revenue and a $0.21 loss per share (Zacks, via Yahoo Finance); and the explanation that systems are being rented back from an existing customer pending owned data centres (Zacks, via Yahoo Finance). This piece makes no claim about the share-price reaction. Separately from those estimates, whether the quarter beat or missed is judged only against the company’s own previously issued guidance and against the year-ago quarter: the Q2 2026 core outlook (revenue of approximately $194.0 million, core gross margin of 36–38%, core operating margin of (30)% to (32)%), the original full-year 2026 core outlook ($855.0–865.0 million of revenue, 38–41% gross margin, (28)% to (32)% operating margin), and Q1 core revenue of $191.3 million and the Q1 core gross margin of 46.5% (from the GAAP-to-Core gross-margin reconciliation table; the highlights state “47%”) come from Exhibit 99.1 to the Form 8-K filed 2026-06-23, read on SEC EDGAR.

Our arithmetic, labelled as such: the 74.3% GAAP and 103.1% core revenue growth rates and the 29-point gap between them; the 117.0% growth in cost of revenue and the resulting 20.4% decline in gross profit; GAAP gross margins of 14.2% and 31.1%; the negative $6.5 million of incremental gross profit on $76.8 million of incremental revenue; cloud gross margins of 19.5% and 25.6% and the 313% growth in cloud cost of revenue; the customer-warrant add-back at 24.6% of GAAP revenue; the −23.0% GAAP and +16.8% core hardware growth rates; the $1.128 billion customer-warrant balance and its increase from $152.4 million; operating expenses at 2.8x revenue; first-half core revenue of roughly $401 million at a blended core gross margin of about 44%, and the implied second-half of $479–489 million and fourth quarter of roughly $263–275 million, and the 22–28% sequential step that implies; and the observation that the full-year core gross-margin range requires the fourth quarter to exceed the third. These are approximations built on disclosed figures, not reported numbers. The interpretation — that the headline growth rate depends on the warrant judgement, that the hardware line changes sign because of it, and that the economics have not yet caught up with the demand — is our analysis, not a company statement, and is not a forecast.
