Person
Economist at Ramp who studies enterprise AI adoption and spending trends, tracking how businesses allocate budgets across AI vendors.
OpenAI roughly matched Anthropic in September on spending by about 120,000 shared customers, up from a quarter at the start of the year, OpenRouter data shows. Both labs are now cutting small-model prices before planned IPOs, so share costs each of them revenue per request.
Reality
Reported quarterly revenue of $11.6 billion against OpenAI's $6.7 billion resets the enterprise-AI question. The pricing and concentration data underneath it flatter neither company.

Ramp's AI Index shows US corporate token use up about 50% since July while AI spending fell, as effective token prices dropped 41%. Usage has not grown enough to cover the price cut, so competition between OpenAI and Anthropic has so far moved revenue from the two sellers to their customers.
Reality
Anthropic and OpenAI shipped cheaper model tiers minutes apart on Tuesday. OpenAI halved Sol's posted token prices, and the only per-task cost comparison between the two labs so far comes from OpenAI itself.

Sol now bills $2 and $10 per million tokens and Luna $0.10 and $0.50, while OpenAI quotes its own benchmark results per task, where the cheap model lands 2.2 points behind Sol on the software engineering test.
Reality
Ramp's September index has the top 1% of US AI buyers paying $7,205 a head. Its chief economist points to August vacations, cheaper tokens and a steady migration down from frontier models.
Reality
Ramp's 80%-from-1% figure travelled fast, but the spend table underneath it prices the trade better, because the top percentile's $7,400 per employee per month is a wage bill rather than a software line.
Reality
Anthropic still leads by about four points in Ramp's July card data, and the gap has doubled since May, yet Ramp's own economist says OpenAI is the faster grower in the quarter to date, which leaves that July snapshot doing very little work.
Reality
The share buying model-serving platforms went from 4.5% in January to 6.1% in July, and two named buyers have now moved production work onto Chinese open weights while incumbent revenue has not yet moved.
Reality
Ramp's July file still has Anthropic ahead on business adoption, and the month's gain went its way too. The catch-up story rests on a list price and a data-retention notice.
Reality
SemiAnalysis says a $200 plan can yield $8,000 of Anthropic API-equivalent usage and $14,000 of OpenAI's. Even the best published caching fix leaves the gap several times wide.
Reality
Ramp puts Anthropic at nearly 44% of its paying business users in July, OpenAI at nearly 40%. The lead is wider than in May, but the growth rate now runs the other way.
