Anthropic may be pricing well below its $1.5 trillion target for its initial public offering, but it’s reportedly gaining ground in the enterprise AI race.
The AI company behind Claude claims a larger share of corporate spending as businesses increasingly turn to its models over OpenAI, according to the latest Ramp AI Index.
Anthropic captured 60.5% of business AI token spending in the week ended Oct. 23, compared with 35.1% for OpenAI, the parent company of ChatGPT.
The shift marks a significant change in just four weeks. Anthropic’s share climbed from 51.3% in September, while OpenAI’s fell from 44.2%, giving Anthropic a growing lead in a market where the two companies account for the vast majority of tracked spending.
Anthropic Gains Ground As AI Usage Grows
The spending gap also showed up in token volume, which measures how much information businesses process through AI models. Anthropic accounted for 59.8% of token volume, compared with OpenAI’s 37.2%.
Other providers were considerably further behind. Elon Musk’s xAI captured 2.2% of token spending, followed by Google at 1.9%.
Overall token spending rose 8.9% from the same week a month earlier, while token volume increased 37.1%.
Faster usage growth coincided with falling prices. The blended price per million tokens for OpenAI and Anthropic dropped 26.8% to $0.56. OpenAI’s average price fell 42.4% to $0.46, while Anthropic’s declined 15.7% to $0.61.
More Than Half Of Businesses Now Pay For AI
The broader adoption picture shows AI becoming increasingly embedded in corporate spending. Ramp found that 55.9% of U.S. businesses it tracked paid for AI products or services in September, up from 55.2% in August and 12.1 percentage points from a year earlier.
Anthropic had a 43.8% adoption rate, compared with 40.6% for OpenAI. However, OpenAI saw stronger monthly growth, with adoption increasing 1.1 percentage points, versus a 0.2-point gain for Anthropic.
AI adoption was highest among information-sector businesses, at 79.9%, followed by finance and insurance companies at 73.7% and manufacturers at 60.9%.
A Small Group Of Companies Is Driving AI Spending
While AI adoption continues to spread, spending remains heavily concentrated among a relatively small group of businesses. Companies paying for AI spent a median of $15.70 per employee per month in September, up from $14.74 in August.
The figures were dramatically higher among the biggest AI spenders. The top 10% of companies spent a median of $813.43 per employee monthly, while the top 1% spent $9,567.53.
Ramp’s AI Index is based on transaction data from more than 85,000 U.S. businesses using its corporate cards and bill-pay platform. However, the company notes that its adoption figures likely undercount actual usage because they exclude free AI tools and employees using personal accounts for work.
The findings suggest that while AI adoption is spreading across industries, Anthropic is gaining a larger share of spending from businesses already using the technology.
