The Ramp AI Index report reveals that AI adoption among American businesses has stalled at 45% as of November. There were slight declines in adoption rates in the finance and technology sectors, while OpenAI's usage dropped by 1% to 34.8%. In contrast, competitors Anthropic and Google gained traction, with their user adoption rising by 0.8% and 0.7%, respectively. The report highlights a need for either significant technological improvements or more effective implementation strategies for a new wave of adoption to occur. Some industries, particularly retail, construction, and manufacturing, saw slight increases, suggesting areas where adoption may still grow. Google's AI, particularly its Gemini model, is gaining momentum, with a 0.7% increase in adoption, marking its second-highest monthly growth. Changes in methodology now estimate Gemini's adoption rate around 4%, reflecting better tracking of API usage. This growth is noteworthy for Google, which has managed to attract new customers beyond its existing Workspace and Cloud users. In contrast, OpenAI's drop in adoption shouldn't be overemphasized. The AI landscape is rapidly evolving, and OpenAI's previous surge in 2025 may be stabilizing as competition heats up. Despite recent fluctuations, OpenAI remains the dominant player in business AI adoption.
