The Ramp data: a snapshot of enterprise AI spending
According to a TechCrunch report published on May 13, 2026, spend management platform Ramp has analyzed corporate card transactions and found that Anthropic now serves more business customers than OpenAI. The data comes from Ramp's aggregation of thousands of companies' software spending, providing a real-time window into which AI tools enterprises are actually buying. Ramp's analysis does not disclose absolute customer numbers, but the relative ranking shift is significant: just months ago, OpenAI led the category by a wide margin. This reversal suggests that Anthropic's Claude models, often favored for their safety features and reliability, are gaining traction in the corporate world.
Ramp's data covers card swipes at thousands of businesses, from startups to Fortune 500 companies. It tracks subscription payments to AI services, giving a direct measure of active paid accounts. While OpenAI still commands a larger share of total spend per customer due to higher-priced tiers and API usage, Anthropic's lead in customer count indicates broader adoption across more organizations — especially among smaller and mid-sized businesses that may have previously defaulted to ChatGPT.
How Anthropic is winning business customers
Anthropic's rise in enterprise adoption is not accidental. In a separate TechCrunch article from the same day, the company announced it is "courting a new kind of customer: small business owners." This marks a deliberate expansion beyond large enterprises and AI researchers. Anthropic has introduced lower-priced plans, simplified onboarding, and industry-specific playbooks for sectors like legal, healthcare, and financial services. These moves directly target the SMB segment that OpenAI has historically dominated through free-tier virality and low-cost ChatGPT Plus subscriptions.
Anthropic also benefits from its reputation as a safer alternative. Cat Wu, a product leader at the company, was quoted in another TechCrunch piece saying that "in the future, AI will anticipate your needs before you know what they are." While futuristic, this vision aligns with the kind of proactive, trustworthy assistant that businesses want — one that minimizes hallucinations and handles sensitive data prudently. Corporate buyers, especially in regulated industries, have been wary of OpenAI's rapid feature churn and occasional data privacy controversies. Anthropic's slower, more deliberate product cadence appeals to risk-averse decision-makers.
The small business push: tailored offerings and pricing
The aggressive push into small business is a key driver of the customer count shift. Anthropic has rolled out a "Claude for Teams" tier that includes shared workspaces, admin controls, and integrated file analysis for $30 per user per month — undercutting OpenAI's ChatGPT Enterprise tier price by about a third. For micro-businesses, Anthropic offers a "Claude Starter" plan at $15 per user per month, with automatic prompt safety filters and a limited message cap. These plans are designed to convert the millions of freelancers and small teams that currently use free or low-cost AI tools into paying customers.
The timing is strategic. OpenAI has recently raised prices for some of its business plans and doubled down on big enterprise contracts with custom models. That leaves a gap in the middle of the market that Anthropic is actively filling. According to the Ramp data, the businesses signing up for Anthropic are not just flash-in-the-pan trials; they show consistent month-over-month spending, indicating genuine utility rather than experimentation.
What this means for OpenAI and the broader AI market
OpenAI remains the household name and the leader in developer API usage, as well as in media mindshare. Sam Altman's company continues to raise massive funds and maintain a higher valuation. However, the Ramp data reveals a vulnerability: brand recognition does not guarantee enterprise dominance. While OpenAI has thousands of direct business accounts through ChatGPT Enterprise and API subscriptions, Anthropic's lead in customer count suggests that the market is fragmenting. Enterprises are no longer relying on a single AI provider; many are adopting multi-model strategies, and Anthropic is frequently the second vendor chosen.
This trend has implications for investors and startup founders in the AI ecosystem. If Anthropic can sustain this trajectory, it may attract more funding and potentially close the valuation gap with OpenAI. The company's focus on safe, interpretable AI has become a competitive differentiator rather than a limitation. Meanwhile, OpenAI is expected to respond with more aggressive SMB offerings or pricing changes. The next few quarters will be crucial in determining whether this is a temporary shift or a permanent reordering of the enterprise AI landscape.
It is worth noting that customer count is not revenue. OpenAI's average revenue per business customer is likely higher due to scale and premium features. But the sheer number of active accounts gives Anthropic a robust base for upsells, data for model improvement, and network effects. As AI assistants become embedded in daily workflows, the provider with more user interactions has an edge in refining its models. Anthropic is now well-positioned to compete on that front.
Forward-looking analysis
The Ramp data serves as an early warning for OpenAI and a validation of Anthropic's strategy. It also signals to the market that enterprise AI procurement is maturing: buyers are actively evaluating multiple vendors and making choices based on trust, safety, and total cost of ownership. This is a fundamentally different dynamic from the early land-grab phase where companies signed up with whoever had the flashiest demo. Anthropic's disciplined product approach and emphasis on alignment are resonating with the practical needs of business customers. If this trend continues, we may see a duopoly in enterprise AI far sooner than expected — with Anthropic and OpenAI splitting the market, while smaller players compete for niches.
TechCrunch's report, combined with the companion stories about Anthropic's small business push and Cat Wu's vision, paints a clear picture: Anthropic is no longer just the safety-conscious alternative; it is becoming the default choice for businesses that want AI without the edge. For the AI/tech community, this is a narrative worth tracking closely, as it will influence everything from investment patterns to regulatory conversations around AI governance.
