Key Takeaways
- Cerebras’s own core gross margin fell to 40.6% in Q2 2026 from 46.5%, but GAAP reported gross margin, collapsed far more sharply, to 14.45% from 44.56% the prior quarter.
- Free cash flow burn nearly quadrupled, widening to negative $476.7 million in the quarter ended June 30, 2026 from negative $119.6 million in Q1, as Cerebras races to build data center capacity for OpenAI and other customers.
- CEO Andrew Feldman and CTO Sean Lie sold roughly $200 million combined in Class A shares between August 20 and September 4, cutting Feldman’s direct stake to 16,853 shares.
- Despite the margin and cash trends, Wall Street’s mean price target actually rose slightly to $291.64 from $291.09 even as shares fell about 10% since June, still implying 147% upside from the September 18 close.

Cerebras’s “Core” Revenue and Margin Framing Diverges Sharply From Its GAAP Numbers
Cerebras’s inference cloud business remains the growth engine. Core cloud and other services revenue grew 287% year over year to $127.7 million in Q2, pushing total core revenue up 103% to $209.9 million, ahead of the $194.2 million analysts expected. But core revenue is a non-GAAP figure management constructs itself, and GAAP reported sales were lower, at $180.1 million.
The gap widens further on margin. Management’s core gross margin fell to 40.6% from 46.5% the prior quarter, which it attributed to renting back its own systems from cloud customers to meet demand.
CBRS’s GAAP gross margin data tells a starker story, margin collapsed to 14.45% in the quarter ended June 30, 2026, down from 44.56% in Q1, a roughly 30 point drop compared with the 6 point core decline management cited on the Q2 earnings call. Both figures move the same direction, but the size of the gap is the real story. Investors relying only on management’s core framing are seeing a meaningfully softer picture than the GAAP statements show.
Cerebras Stock’s Cash Burn Is Accelerating as It Chases OpenAI-Sized Backlog
The margin pressure lines up with a sharp acceleration in cash burn. Free cash flow widened to negative $476.7 million in the quarter ended June 30, 2026 from negative $119.6 million in Q1, a roughly fourfold increase in one quarter. Cerebras is spending to build the capacity behind its $25.4 billion backlog, anchored by a $20 billion, 750 megawatt OpenAI agreement and management’s plan to more than triple core revenue in 2027. CFO Bob Komin has said Cerebras is reimbursed for part of its data center fit out costs by its largest customer, but the free cash flow trend shows the company is still funding a large share of that buildout itself.
Cerebras ended the quarter with $8.6 billion in cash and an unused $850 million credit facility, which comfortably covers several quarters of burn at the current rate. The immediate risk is not liquidity, it is whether this pace of spending converts into revenue fast enough to narrow the gap before that cushion matters more.

Cerebras Executives Sold Heavily Right After the Post-IPO Lockup
Cerebras went public in May 2026 at $185 a share and has traded as high as $220 since, closing at $198.37 on September 18. Starting in mid August, insiders began selling in size. CTO Sean Lie disposed of about 710,000 Class A shares worth roughly $145.7 million on August 20 and 21, cutting his direct holding to 368,926 shares. CEO Andrew Feldman sold 243,559 shares under a 10b5-1 plan adopted in May, worth about $47.75 million, then sold another $7.96 million worth on September 4, leaving his direct stake at just 16,853 shares. Director Steven Vassallo’s trust separately sold roughly $10.9 million in shares distributed by early venture backer Foundation Capital.
10b5-1 plans are scheduled in advance, and post IPO diversification by long tenured founders is common. But the scale and clustering of these sales landed in the same window as the GAAP margin collapse and the cash burn acceleration, not just the milder core figures management highlighted publicly.
Has Wall Street Priced In Any of This?
So far, the sell side does not appear to have reacted. Street price targets on Cerebras barely moved between June 30 and September 18, even as the stock fell about 10% to $198.37. The mean target actually ticked up slightly, to $291.64 from $291.09, and the median held at $300, with 7 buys and 3 outperforms against just 1 hold among 11 analysts. That implies roughly 147% upside from the current price, up from 132% in June, mechanically because the stock fell while targets stayed put. Only one additional analyst moved to no opinion.
That gap, GAAP margin cratering, cash burn quadrupling, and executives selling nine figure sums, against a Street that has not cut a single price target, is the real tension in this stock. It does not necessarily mean the bulls are wrong, core revenue and backlog growth are genuine. But the next test is concrete, whether Q3 GAAP gross margin and free cash flow stabilize, or whether analysts eventually have to reconcile their targets with the numbers beneath management’s core framing.
