Cerebras Systems has grown revenue roughly 2.5 times over eight quarters, while BigBear.ai has largely stalled, exposing a widening gap between the two artificial intelligence companies.
Cerebras Systems (NASDAQ: CBRS) reported consistently higher revenue totals than BigBear.ai (NYSE: BBAI) across all eight observed quarters, according to company filings reviewed through September 11, 2026.
The two companies are capitalizing on the artificial intelligence boom through fundamentally different business models, which is directly reflected in their contrasting revenue trajectories.
BigBear.ai generates revenue by providing AI-powered predictive modeling and security consulting services to enterprise and government clients across the United States and internationally.
Cerebras Systems earns revenue by selling specialized computing hardware and software to data centers and large enterprises seeking superior processing speed for AI workloads.
BigBear.ai experienced several consecutive quarters of year-over-year sales declines before finally breaking that trend in the second quarter of 2026 with 13% growth over the prior year period.
That growth was largely attributed to its acquisition of Ask Sage, an AI platform specifically tailored to the operational needs of government clients.
During the summer, BigBear.ai also established a new equity offering program, gained international regulatory approval for airport security screening software, and appointed a new board member, though it posted an operating margin of -74% for the quarter ended June 30, 2026.
Cerebras Systems saw revenue rise in each quarter until posting $180.1 million in Q2 2026, a figure that reflected a decline driven by softer hardware sales during the period.
Despite that dip, Cerebras displayed a fluctuating but overall upward revenue trend across the eight-quarter evaluation period, compared with the flat and inconsistent trajectory seen at BigBear.ai.
Cerebras also announced a new multi-year data center capacity agreement in Finland and expanded an existing manufacturing relationship, though it simultaneously faced multiple legal investigations regarding potential securities law violations.
The company reported an operating margin of -265% for the quarter ended June 30, 2026, underscoring that heavy investment costs remain a significant burden even as sales growth continues.
BigBear.ai’s inconsistent quarterly revenue performance positions it as a more speculative investment compared to Cerebras, which has demonstrated stronger and more consistent customer adoption over the observed period.
Investors tracking the artificial intelligence sector will find that revenue trend analysis between these two companies signals very different competitive positions heading into the second half of 2026.
