penAI is courting businesses left and right. Data from the billing startup Ramp shows that OpenAI is maintaining a stark lead over Anthropic and Google in AI spending. According to the report, around 36.8% of businesses that use Ramp pay for OpenAI products. 

Anthropic holds second place in the Ramp study at 16.7%. Google trails far behind that at 4.3%, though this number might be under-reported, as many businesses get Gemini services for free through their Google Workspace deployments.

Let's keep in mind that Ramp is especially popular with startups and small businesses, though it reportedly has a growing list of enterprise clients. Still, Ramp has only been around since 2019, while many Fortune 500 companies have long relationships with legacy expense and billing systems like Oracle. So, Ramp's data is likely heavily skewed toward SMBs. That helps explain why the Ramp report contradicts recent research from sources such as Menlo Ventures, which show that Anthropic has been extending its lead over OpenAI in enterprise AI market share.

Anthropic has also scored a slew of enterprise deals in the last several months, including with IBM, Deloitte, Accenture, Cognizant and Allianz Global. The company announced its latest partnership on Thursday: A deal to bring Claude to nearly 10,000 employees at insurance firm Travelers.

Additionally, the recent launch of Claude Cowork, though still in beta and available only to premium subscribers, could attract even more business customers. “With Claude [Cowork] … Anthropic took the angle delivering value for the enterprise right away.” Brian Jackson, principal research director at Info-Tech Research Group, told The Deep View. 

Google, meanwhile, has its own advantages. It too has struck major deals to weave Gemini throughout companies like Walmart, Oracle and PwC. Its workplace suite is also widely used by millions across enterprises, making turning on Gemini features very turnkey.
