Cerebras Systems Inc (NASDAQ: CBRS) shares surged 11.58% to $261.95 on Wednesday as investors positioned for the AI chipmaker's second-quarter earnings report, scheduled after the market close. The stock's momentum reflects strong market confidence in the company's strategic partnerships with hyperscalers like OpenAI and Amazon Web Services (AWS), despite expected margin pressure.

Wall Street analysts project a second-quarter loss of 17 cents per share on revenue of $194.20 million. This figure aligns closely with Cerebras' own guidance of approximately $194 million in core revenue, issued alongside first-quarter results. If met, this would represent an 88% year-over-year increase from the prior year period. The results would build on a first quarter where core revenue reached $191.3 million, up 12% sequentially and 92% year-over-year.

What the Numbers Show

A significant divergence exists between Cerebras' top-line growth and its profitability trajectory. While core revenue is projected to surge 88% year-over-year, gross margins are expected to contract sharply. The company guided core gross margin to 36% to 38%, down from approximately 47% in the first quarter. This margin compression is attributed to reliance on costly third-party capacity while bringing additional data-center capacity online.

Partnership and Capacity Highlights

The partnership with Advanced Micro Devices (NASDAQ: AMD) remains central to the narrative. Announced in July, the collaboration splits AI inference tasks: AMD’s Helios rack-scale systems process prompts and large context windows at high throughput, while Cerebras’ Wafer-Scale Engine handles latency-sensitive token generation. This setup, termed “disaggregated inference,” sees Helios systems set to deploy in Cerebras data centers in the second half of 2026.

The first quarter’s biggest headline was Cerebras’ new agreement with OpenAI, a multi-year deal valued at more than $20 billion under which OpenAI will deploy 750 megawatts of Cerebras’ inference computing capacity. The two companies also co-launched Codex-Spark, a coding model built for near-instant responses. Cerebras separately began a multi-year partnership with AWS to scale fast inference computing, under which AWS’s Trainium 3 chips will handle prefill processing while Cerebras’ CS-3 systems run decoding.

Technical Levels to Watch

CBRS is trading well above its short-term trend markers, sitting about 27% over the 20-day SMA at $207.43 and about 26% over the 50-day SMA at $208.82. That positioning shows strong upside extension compared with the recent consolidation zone. Even so, the 20-day SMA is still below the 50-day SMA, which keeps the longer-term trend repair process unfinished even as price moves higher.

MACD is offering the clearest read on momentum. It is above its signal line and the histogram is positive, which points to improving momentum compared with the previous downswing. In simple terms, MACD above the signal line suggests sellers are losing influence and buyers are gaining control even if the broader trend has not fully shifted.

From a levels standpoint, the stock is sitting near the midpoint of its 52-week range, which spans from $160.81 to $386.34. After a swing low in June and a swing high in May, the current move looks like a continuation attempt off that June base. Trend-focused traders will be watching to see if price can stay above the short-term averages long enough to eventually flip the 20-day and 50-day relationship back to bullish.

Kaplan Fox & Kilsheimer LLP is investigating potential securities law violations by Cerebras Systems Inc. (NASDAQ: CBRS) after the artificial intelligence infrastructure company’s stock price dropped 19.61% in a single trading session. The investigation targets disclosures surrounding the company’s initial public offering and subsequent financial guidance, which may have misled investors about operational costs and margin sustainability.

The probe was announced on August 5, 2026, following a sharp decline in Cerebras’ share price from $226.72 on June 23, 2026, to $182.26 on June 24, 2026, a loss of $44.26 per share. This market reaction occurred immediately after Cerebras reported its first-quarter fiscal year 2026 results and provided outlook details for the second quarter of fiscal year 2026.

Cerebras, which designs and manufactures AI compute platforms including processors and data centers, conducted its initial public offering on or around May 14, 2026. The company sold 30 million shares of Class A common stock at an offer price of $185 per share.

Operational Cost Concerns

During the earnings call on June 23, 2026, Cerebras’ Chief Financial Officer disclosed that the company is temporarily renting its own systems back from an existing customer to accelerate service delivery for its contracted backlog. This strategy aims to make capacity available sooner while the company builds out its own data center infrastructure.

The CFO stated that the additional cost of renting third-party capacity will depress core cloud and other services margins temporarily from current levels. The company expects this impact to decrease margins by 10 to 15 points based on anticipated volumes before ramping back toward a target margin of 60% plus as it transitions away from rented systems.

What the Numbers Show

The disclosure reveals a significant dependency on third-party capacity to meet near-term demand, creating a temporary but substantial drag on profitability. While the company maintains a target margin of 60% plus, the immediate outlook suggests a double-digit percentage point reduction in core cloud margins. This divergence between long-term targets and short-term execution highlights the capital intensity of scaling AI infrastructure rapidly.

Investors who suffered losses or possess information relevant to the investigation are urged to contact Kaplan Fox & Kilsheimer LLP. The firm, founded in 1956, has recovered more than $10 billion for clients in securities, antitrust, and consumer protection actions nationwide.
