B2B採用でAnthropicがOpenAIを逆転

anthropic has surpassed openai in b2b adoption for the first time, with ramp data showing 34.4% of companies now pay for claude versus 32.3% for chatgpt. anthropic quadrupled its penetration over the past year while openai remained relatively flat. however, ramp economist ara kharazian notes that anthropic generates more revenue from expensive models, potentially pushing budget-conscious clients toward cheaper alternatives. furthermore, the index tracks billing prevalence rather than total spend or usage volume, meaning the lead may reflect pricing strategies and customer acquisition more than market dominance. rising costs for new models like opus 4.7 and growing competition from open-source inference platforms could quickly erode anthropic's advantage.
