Arm and SoftBank Made Play for Cerebras Weeks Before IPO; AI Chipmaker Rejected the Approach

Arm Holdings and its majority owner SoftBank Group approached Cerebras Systems about a potential acquisition just weeks before the AI computing firm was expected to go public, according to sources familiar with the matter. Cerebras rebuffed the preliminary overture, opting instead to proceed toward its initial public offering. The revelation signals intense strategic interest in AI computing infrastructure at the highest levels of the semiconductor industry.

Cerebras, known for its wafer-scale chip technology designed to handle massive AI workloads, had been preparing for a public listing at a time when investor appetite for AI-adjacent businesses remained elevated. The approach from Arm and SoftBank underscores how major players in the chip ecosystem have been weighing acquisitions as a faster path to expanding capabilities in the artificial intelligence market. Arm, which licenses chip architecture foundational to most mobile devices worldwide, has been seeking to deepen its position in AI-specific computing, while SoftBank has been rebuilding its portfolio around next-generation technology investments.

The timing of the approach—reportedly weeks before Cerebras's expected IPO—suggests SoftBank sought to potentially intercept the listing and bring the company into its existing semiconductor holdings, which already include Arm. Whether the offer carried a specific price remains unclear. Cerebras's decision to decline and continue toward an IPO highlights the company's confidence in its standalone valuation and growth prospects as a publicly traded entity. The development is likely to draw scrutiny from regulators and investors watching how major tech conglomerates pursue AI chip assets in an increasingly competitive landscape.
