Ramp data reveals Anthropic has outpaced OpenAI in business customer base, underscoring the intensifying competition in enterprise AI services and challenging OpenAI's market dominance.
Anthropic has emerged as the leading provider of AI services to businesses, according to data compiled by fintech firm Ramp. The survey, which analyzed expense data from Ramp’s clients, shows that 34.4% of participating businesses are paying for Anthropic's services, surpassing OpenAI’s 32.3%. This shift in market dynamics highlights the growing competition in the enterprise AI space and the strategic positioning of both companies.
The rise of Anthropic as a preferred choice among businesses is significant given the established presence of OpenAI. OpenAI has long been at the forefront of AI innovation, backed by Microsoft’s substantial investments and partnerships with leading tech firms. However, Anthropic’s ability to attract a larger share of business customers suggests that it may be offering more compelling solutions or better value propositions.
One key factor could be Anthropic's focus on enterprise-specific applications and its alignment with corporate needs. The company has been proactive in addressing concerns around data privacy, security, and customization, which are critical for businesses. In contrast, OpenAI’s broader approach to AI development may have diluted its focus on specific business requirements.

The market share shift from OpenAI to Anthropic presents several investment implications. For investors in the AI sector, this data suggests a growing demand for specialized enterprise solutions. Companies that can effectively cater to these needs are likely to gain a competitive edge and capture more market share.
From a financial perspective, the increasing adoption of Anthropic’s services by businesses could translate into higher revenues and profitability. This is particularly relevant as the enterprise AI market continues to expand, driven by the growing importance of AI in various industries. According to a report by MarketsandMarkets, the global AI software market is expected to reach $126 billion by 2025, with significant contributions from the enterprise segment.
However, investors should also be cautious about the risks associated with this rapidly evolving market. The high competition and rapid technological advancements mean that companies must continuously innovate to maintain their competitive edge. Any failure to keep up with emerging trends or address customer needs could result in a loss of market share.
The data from Ramp highlights the dynamic nature of the enterprise AI market and the potential for Anthropic to capitalize on its strengths. As the sector continues to grow, investors should closely monitor the strategies and performance of key players like Anthropic and OpenAI to make informed investment decisions.

About the author
Marcus began tracking AI's market implications in 2016, noticing AI-related patent filings accelerating ahead of earnings upgrades before most of the sell-side had caught on. A former fixed-income quantitative analyst, he spent two decades building models that priced risk across emerging markets before pivoting to cover the economic impact of AI full-time. His writing translates opaque technical developments into clear risk/reward terms — and he's rarely diplomatic about the gap between AI valuations and underlying fundamentals. He believes most market participants still underestimate AI's long-run deflationary effect on knowledge work.
