Anthropic Surpasses OpenAI in B2B AI Adoption Milestone, Ramp Data Reveals
In a significant shift within the generative AI landscape, Anthropic has overtaken OpenAI in business-to-business adoption for the first time, according to spending data from Ramp, a leading corporate spend management platform. This development, tracked through Ramp’s aggregate analysis of API credit purchases by enterprise customers, underscores Anthropic’s rapid ascent powered by its Claude family of models.
Ramp’s data, drawn from transactions across thousands of businesses using its platform, provides a real-time pulse on AI vendor preferences. The report highlights monthly spending on AI API credits, a key proxy for production-level adoption in B2B environments. For June 2024, Anthropic claimed the top spot with higher spend volumes than OpenAI, marking the inaugural month of leadership. This crossover occurred after consistent growth trajectories, with Anthropic’s spend surging ahead in the latter half of Q2 2024.
Visualized in Ramp’s charts, the trend is stark. OpenAI dominated early, peaking with substantial leads through much of 2023 and into early 2024. However, Anthropic’s trajectory accelerated dramatically. From January 2023 to July 2024, Anthropic’s B2B spend grew by over 8,500 percent year-over-year in recent periods, outpacing OpenAI’s expansion, which, while impressive at over 1,500 percent initially, began to moderate. By mid-2024, Anthropic consistently hovered at or above OpenAI’s levels, culminating in the June flip.
This data focuses specifically on API credits, reflecting committed usage in enterprise workflows rather than casual consumer subscriptions like ChatGPT Plus. Businesses procure these credits in bulk for integrating large language models into applications, analytics tools, customer support systems, and internal automation. Ramp notes that such purchases indicate deeper, scalable deployments, distinguishing them from one-off experiments.
Behind the numbers lies Anthropic’s strategic focus on enterprise-grade capabilities. The launch of Claude 3.5 Sonnet in late June 2024 propelled further momentum, with its benchmark-leading performance in coding, reasoning, and multimodal tasks resonating in commercial settings. Ramp’s analysis shows Anthropic capturing a larger share of high-volume spenders, including sectors like finance, healthcare, and software development, where reliability, safety features, and cost-efficiency are paramount.
OpenAI remains a formidable contender, holding second place with robust ongoing demand for GPT-4o and related models. The gap between the two narrowed progressively from April onward, with both vendors far outstripping others. Third-place Mistral AI and fourth-place Cohere trail significantly, while Google Cloud’s Vertex AI and Microsoft’s Azure OpenAI services round out the top tier, albeit with lower individual spends.
Ramp’s broader State of AI Spend report contextualizes this rivalry within exploding enterprise investment. Total AI-related spend on its platform skyrocketed from negligible levels in early 2023 to tens of millions monthly by mid-2024, a testament to AI’s embedding in corporate operations. Key drivers include plummeting inference costs, enabling broader experimentation, and maturing APIs that support fine-tuning and retrieval-augmented generation pipelines.
The platform’s dataset, while not exhaustive of all global B2B activity, offers unparalleled granularity due to Ramp’s position as a spend aggregator for startups and scale-ups. It captures pre-reimbursement purchases, providing a forward-looking indicator of adoption velocity. Notably, the data excludes internal hyperscaler usage or indirect procurement channels, focusing on direct vendor billing.
This overtake signals intensifying competition in the foundational models arena. Anthropic’s constitutional AI approach, emphasizing alignment and interpretability, appeals to risk-averse enterprises navigating regulatory scrutiny. Meanwhile, OpenAI’s ecosystem advantages, including widespread developer familiarity, sustain its stickiness. Ramp predicts sustained volatility, with model releases and pricing adjustments likely to sway monthly rankings.
For technical leaders evaluating vendors, Ramp’s insights advocate monitoring spend patterns alongside benchmarks. Factors like context window sizes, rate limits, and safety guardrails influence long-term commitments. As B2B AI matures, such data democratizes visibility into market dynamics, aiding procurement decisions amid hype cycles.
This milestone not only validates Anthropic’s engineering prowess but also highlights the commoditization of frontier AI, where performance parity drives vendor selection. Businesses are voting with dollars, prioritizing tools that deliver measurable ROI in production environments.
