Business spending on OpenAI models jumps to a record, new data shows (www.businessinsider.com)

OpenAI has achieved record business spending with over 36.8% of US businesses utilizing its AI models, reflecting an increase in recurring use in key areas like software development, research, and customer support. According to data from Ramp, a financial analytics startup, 46.6% of US businesses paid for AI services in December 2025, marking the largest growth since mid-2025. This resurgence indicates a shift from trial usage to consistent integration of AI into everyday functions, underscoring OpenAI's leading position in the enterprise AI market against competitors like Anthropic and Google. The data highlights a significant rebound for OpenAI, with a 2% increase in business adoption since November, reversing a temporary slowdown. While Anthropic and Google saw slower growth rates at 16.7% and 4.3% respectively, the overall acceleration in AI spending suggests that businesses are moving beyond experimentation towards more strategic application of AI tools. It's important to note that Ramp's figures likely underestimate true adoption rates, as they do not account for free AI tool usage or personal accounts, indicating even broader engagement within the AI landscape.
