Challenging Anthropic's Narrative
In a candid internal communication, OpenAI's Chief Revenue Officer, Denise Dresser, has launched a pointed critique against its significant competitor,
Anthropic. The memo, a substantial document, systematically dissects Anthropic's business practices and public persona. Dresser's analysis extends to Anthropic's financial accounting methods, its approach to securing computational resources, and the very ethos that underpins its existence. This internal assessment is particularly noteworthy given Anthropic's recent ascent in the AI market, with its Claude models gaining considerable traction. Dresser’s communication suggests a heightened sense of urgency within OpenAI, describing the market as intensely competitive and dedicating significant portions of the memo to deconstructing Anthropic’s claims and market positioning. The memo implies that OpenAI perceives Anthropic's narrative as potentially misleading and seeks to counter it internally.
Revenue Accounting Discrepancies
A central point of contention raised by OpenAI revolves around Anthropic's reported revenue figures. Dresser alleges that Anthropic employs accounting practices that artificially inflate its financial performance. Specifically, she points to the way Anthropic accounts for revenue-sharing agreements with major cloud providers like Amazon and Google. Instead of reporting net revenue, which represents the actual income after partner payouts, Anthropic allegedly reports gross revenue. OpenAI claims this accounting method adds approximately $8 billion to Anthropic's reported revenue. If these figures were adjusted to reflect net revenue, Anthropic's annualised run rate would reportedly decrease from $30 billion to around $22 billion, placing it below OpenAI's own reported $24 billion. Anthropic, however, disputes this interpretation, asserting its position as the principal party in these transactions, with cloud partners acting merely as distribution channels, thus justifying its gross revenue recognition.
Compute Strategy and Availability
Beyond financial metrics, Dresser also scrutinizes Anthropic's strategic decisions regarding compute acquisition, terming it a significant misstep. OpenAI asserts its own aggressive expansion in computational power, having secured 8 gigawatts of capacity and aiming for 30 gigawatts by 2030. In contrast, OpenAI estimates Anthropic will only reach 7 to 8 gigawatts by the end of 2027. Dresser suggests that this disparity in compute resources directly impacts Anthropic's product performance, leading to issues like throttling and reduced availability of its services. This difference in strategic foresight regarding essential infrastructure is presented as a key differentiator and a potential vulnerability for Anthropic, impacting its ability to scale and serve its user base effectively, especially in the demanding enterprise market.
Philosophical Divide in AI
Dresser sharply criticizes Anthropic's underlying philosophy, characterizing its narrative as one built on "fear, restriction, and the idea that a small group of elites should control AI." This is a direct counter to OpenAI's publicly espoused mission of democratizing AI. This characterization echoes previous statements from OpenAI CEO Sam Altman, who has previously described Anthropic's product as "expensive" and catering to a privileged few. The accusation implies that Anthropic's approach is inherently exclusionary and fear-driven, whereas OpenAI positions itself as the more open and accessible force in artificial intelligence development. This philosophical framing is crucial as both companies vie for market leadership and public perception.
Enterprise Focus and Future Outlook
The memo's overarching message is a call to action for OpenAI to intensify its efforts in the enterprise sector. Dresser urges a strategic shift from viewing OpenAI as a company with multiple distinct products to one that operates as a comprehensive platform with integrated offerings. The increasing prevalence of substantial, multi-year deals with enterprise clients highlights the critical importance of this market segment, which OpenAI is determined to secure and expand. Both OpenAI and Anthropic are reportedly on paths toward initial public offerings (IPOs) this year, intensifying the competitive narrative. The financial and strategic battles being waged now are likely precursors to the stories investors will hear during their respective IPO roadshows, making the current rivalry a significant indicator of their future valuations and market positions.
