OpenAI is showing renewed momentum with business users in a new data set from Ramp, according to TechCrunch. The readout is narrow but useful: it covers spending by more than 70,000 American businesses that use Ramp’s bill pay and corporate card products, rather than the full enterprise artificial intelligence market. The headline from the data is not that OpenAI has retaken the lead. TechCrunch reports that Anthropic passed OpenAI among Ramp’s paying business users in May, when Anthropic reached 41% share versus OpenAI’s 39%. By July, Anthropic still led, at nearly 44% versus OpenAI’s nearly 40%. The change is in the recent direction of travel. Citing Ramp economist Ara Kharazian, TechCrunch reports that OpenAI is currently growing faster than Anthropic among this Ramp customer segment in Q3 to date. The quarter is not over, and Ramp did not disclose actual dollars spent, sharing only percentage-based data. That caveat matters. Ramp’s sample includes businesses across industries, but TechCrunch notes that the customer base skews toward technology companies. It also excludes large enterprises that may route spend through other providers, including American Express, rather than Ramp. The data therefore works best as a market signal, not a full accounting of enterprise AI revenue. Still, the signal is important because both OpenAI and Anthropic remain private, and their detailed financials are not available. Until either company releases fuller numbers closer to a public listing process, third-party spending data is one of the few ways to track how business adoption may be shifting between the two labs. The volatility is the story. TechCrunch’s reading is that businesses appear willing to move spend back and forth as labs release new models. That cuts against a simple assumption that enterprise AI subscriptions are already deeply sticky. In this sample, Anthropic’s lead has not ended OpenAI’s ability to regain momentum. Ramp’s data also suggests the category itself is still expanding. TechCrunch reports that the percentage of Ramp customers paying for AI topped 50% in March and rose to nearly 56% by July. That means OpenAI and Anthropic may both be growing business revenue even while fighting over relative share inside the sample. Kharazian also posted on X that OpenAI’s “GPT-5.6 Sol” was increasingly becoming a developer choice, while “Fable 5” disappointed in adoption and real-world application given price and data-retention requirements, according to TechCrunch. The outlet cautions that this may oversimplify the comparison, noting that Fable is Anthropic’s higher-end model tier and is aimed at a more targeted set of use cases than a general chatbot. Who benefits: OpenAI benefits from evidence that it is regaining momentum in this customer sample. Anthropic still benefits from holding the reported July lead among Ramp’s paying business users. Who's exposed: Both companies are exposed if enterprise customers keep switching providers rather than settling into durable, long-term commitments. The data is also limited by Ramp’s customer mix and the absence of disclosed spending dollars.
