TLDRs;
- Cerebras shares fell about 11% after earnings despite cloud and services revenue surging 281% year over year.
- GAAP gross margin dropped sharply to 14%, raising investor concerns about profitability and heavy infrastructure spending.
- Management raised full-year revenue and margin guidance, signaling confidence in sustained AI inference demand growth.
- Analysts remain broadly bullish, but execution and data-center expansion costs are becoming the central debate.
Cerebras Systems shares plunged roughly 11% on Thursday after the artificial-intelligence chip company released second-quarter results that delivered exceptional cloud growth but also highlighted mounting pressure on margins and profitability.
The sharp decline reversed part of the previous session’s rally and underscored a growing divide between investors who are excited about surging demand for AI inference computing and those who are increasingly focused on the cost of scaling that business.
Cerebras reported quarterly revenue of $180.1 million, up 74% from a year earlier. The strongest performance came from cloud and services revenue, which jumped 281% to $126 million and accounted for about 70% of total revenue, compared with roughly one-third a year ago.
Cloud growth steals spotlight
The company’s cloud business has become the primary engine of expansion as enterprises race to deploy AI models that require large-scale inference capacity. Cerebras has positioned itself as an alternative to Nvidia in this market, promoting its wafer-scale architecture as a way to reduce dependence on high-bandwidth memory and advanced packaging.
Chief Executive Andrew Feldman said demand for fast inference remains extremely strong and that the company is expanding aggressively to meet customer needs. Cerebras said it has more than 600 megawatts of data-center capacity either operational or secured through contracts extending into 2027.
The results suggest that customers are adopting the company’s cloud platform at a much faster pace than its traditional hardware products. Hardware revenue fell 23% year over year to $54.1 million, reinforcing the shift toward recurring cloud and services revenue.
Margins become the main concern
GAAP gross profit declined 20% to $25.6 million, while GAAP gross margin collapsed to 14%, down from about 31% a year earlier. Investors appeared to focus on this figure more than on the company’s headline growth numbers.
Cerebras also presented a non-GAAP view showing a 41% core gross margin, creating a wide gap between reported and adjusted profitability. The difference stemmed from accounting adjustments related to pass-through sales and customer-warrant amortization.
Chief Financial Officer Bob Komin said the company’s use of rented computing capacity reduced adjusted gross margin by roughly five percentage points. Management expects margins to improve as a larger share of capacity becomes company-owned rather than leased.
That explanation did little to calm concerns that the current phase of expansion is consuming significant capital before generating durable cash returns.
Guidance points higher
Cerebras now expects core revenue of $880 million to $890 million, up from a previous range of $855 million to $865 million. The company also increased its projected core gross margin to 41%–43% and improved its operating-margin outlook substantially.
The stronger guidance indicates that management sees continued momentum in AI cloud demand through the remainder of the year. The company also ended the quarter with a sizable liquidity cushion, reporting $8.6 billion in cash, restricted cash, and short-term investments, along with $25.4 billion in remaining performance obligations.
Those figures suggest Cerebras has the financial resources to continue building capacity even as profitability remains under pressure.
Wall Street still mostly bullish
Analysts have generally maintained positive ratings on the stock, with price targets ranging from the low $270s to $340 prior to the earnings release. However, the latest results are likely to intensify scrutiny of execution risk.
Morgan Stanley analysts noted that the central debate is no longer whether demand exists, but whether Cerebras can build and utilize capacity efficiently enough to convert that demand into sustainable earnings.
The stock’s volatile trading over the last two sessions highlights that uncertainty. Shares surged more than 11% on Wednesday before tumbling on Thursday as investors reassessed the balance between growth and profitability.
For now, Cerebras remains one of the fastest-growing companies in AI infrastructure. The challenge is that Wall Street is beginning to demand evidence that explosive cloud adoption can eventually produce strong GAAP margins and meaningful cash generation, not just rapid revenue expansion.
