Ramp AI Index: US business AI spending falls while usage rises; OpenAI and Anthropic split token share
Ramp economist Ara Kharazian’s Ramp AI Index finds US companies are spending less on AI while usage has climbed about 50% since a July peak and hit a record high at the end of September. Kharazian attributes the spending drop mainly to competition and price cuts from OpenAI and Anthropic; in the last week of September Anthropic accounted for 51% of token spending and OpenAI 44.5%, while open-source models remain under 5% of spending.
