Pomerantz LLP is investigating claims on behalf of investors of Cerebras Systems Inc. concerning potential violations of federal securities laws by the company and certain of its officers and/or directors. The investigation focuses on whether the entity engaged in securities fraud or other unlawful business practices. This legal scrutiny follows a significant decline in Cerebras's stock price after the release of its first-quarter 2026 financial results.

On or around May 14, 2026, Cerebras completed its initial public offering, selling 30 million shares of Class A common stock priced at $185.00 per share. On June 24, 2026, the company reported its financial results for the first quarter of 2026. Management disclosed that to service near-term demand in its contracted backlog, the company chose to temporarily rent its own systems back from an existing customer while aggressively building out its own data center capacity. The company further revealed that the additional cost of renting third-party capacity would depress its core Cloud and other services margin temporarily from current levels.

Cerebras reported a loss of $0.22 per share, missing analyst estimates of a $0.16-per-share loss. Additionally, the company forecast a narrower gross margin in its core business, excluding impact from customer warrants and data center pass-through revenues. Following this announcement, Cerebras's stock price fell $44.46, or 19.61%, to close at $182.26 per share on June 24, 2026.

Key Financial Details

Cerebras Systems Inc. CEO Andrew Feldman revealed that SpaceXAI, formerly xAI, moved into the business of renting AI computing because its processors were not busy enough. Speaking on the Sourcery podcast on Monday, Feldman attributed the excess capacity to weaker-than-expected early adoption of the Grok model, which left billions of dollars in hardware sitting idle.

Feldman explained that SpaceXAI could not afford to leave equipment unused. "They had these GPUs sitting around, and that’s a bad idea," he said. This situation led SpaceXAI to lease a block of GPUs to Anthropic for use at SpaceX’s Colossus 1 data center in Memphis, Tennessee. Feldman noted that the company realized it could build a strong business by stepping into a constrained market despite its own model's initial struggles.

Anthropic Agreement Terms

Anthropic’s agreement involves the Colossus and Colossus II facilities. The company said the site provides more than 300 megawatts through over 220,000 Nvidia GPUs. This capacity allows Anthropic to double Claude Code limits, remove peak-hour reductions, and raise API ceilings.

Grok 4.5 Launch and Market Position

The leasing deal has not ended the competition between the firms. SpaceXAI launched Grok 4.5 on July 8, describing it as its strongest model for coding, agentic tasks, and knowledge work. Musk characterized the model as "Opus-class."

Despite the rivalry, Musk has softened his public stance toward Anthropic, recently acknowledging it as "obviously currently the leader in AI." He stated he would not weaponize SpaceXAI's compute access against the rival, emphasizing that sabotage was "not my style."
