AI chipmaker Cerebras Systems has officially finalized its initial public offering on the Nasdaq Global Select Market, raising $6.38 billion in aggregate gross proceeds. The closing caps off a highly successful multi-day roadshow that saw intense public market demand force a sharp upward revision of the company’s initial pricing targets and share allocations.
When Cerebras originally announced the launch of its IPO roadshow on May 4, the Sunnyvale-based firm planned to offer 28,000,000 shares of Class A common stock within a targeted price range of $115.00 to $125.00 per share. However, institutional demand drove a dramatic pricing shift. By the time the offering priced on May 13, Cerebras expanded the baseline offering to 30,000,000 shares and priced them at $185.00 per share—a 48% premium above the top end of its original target range.
Trading under the ticker “CBRS,” the stock debuted on May 14, flanked by a massive capital injection. The appetite for the hardware maker was strong enough that underwriters—led by Morgan Stanley, Citigroup, Barclays, and UBS Investment Bank—immediately exercised their 30-day overallotment option in full. This added another 4,500,000 shares to the offering, bringing the final transaction volume to 34,500,000 shares at the closing on May 15.
The multi-billion-dollar liquidity event provides Cerebras with significant balance sheet leverage as it scales production of its flagship Wafer-Scale Engine 3 (WSE-3). By positioning its massive, single-wafer architecture as a power-efficient alternative to dominant GPU clusters, Cerebras is utilizing this public capital influx to aggressively challenge incumbent hardware giants and expand its cloud infrastructure footprints across corporate and sovereign enterprise networks.
