OpenAI exec slams rival Anthropic in internal memo, calling its narrative built on fear and restriction

OpenAI’s chief revenue officer, Denise Dresser, sent an internal memo this week that openly attacks the company’s chief rival, Anthropic. Dresser wrote that “Anthropic’s story is built on fear, restriction, and the idea that a small group of elites should control AI,” echoing CEO Sam Altman’s long‑standing narrative that OpenAI is the more democratic force in the sector. The memo, circulated among OpenAI staff, also accused Anthropic of inflating its compute run‑rate, under‑investing in infrastructure and relying too heavily on a single‑product focus around its Claude models.
The jab arrives amid a sharpening battle for market share, talent and government contracts. OpenAI has pledged to reach 30 gigawatts of compute by 2030, while analysts estimate Anthropic will operate on roughly 7–8 gigawatts. The rivalry intensified after OpenAI’s recent shareholder letter, which two weeks ago labelled Anthropic’s growth curve “meaningfully smaller” and warned that its “coding‑first” strategy could leave it vulnerable in a platform‑centric market. The latest memo pushes the narrative from external investors to the company’s own workforce, signalling a more aggressive internal posture.
Why it matters is twofold. First, the public‑facing tone of an internal document suggests OpenAI is preparing to double down on competitive tactics, potentially influencing hiring, pricing and partnership decisions. Second, the criticism could pressure Anthropic’s backers—most notably Amazon, which announced a $5 billion investment earlier this year—to defend their stake or accelerate their own compute build‑out.
Watch for a response from Anthropic’s leadership in the coming days, as well as any shift in OpenAI’s product roadmap that might aim to undercut Claude’s niche in safety‑focused AI. Analysts will also be tracking whether the memo foreshadows a formal partnership or acquisition push by OpenAI to consolidate its lead before the next wave of government AI contracts is awarded.
