## Summary

The Ramp AI Index, based on transaction data from more than 70,000 US companies, shows an unusually long decline in AI spending while usage reaches a record level at the end of September, up around 50% since the July peak. According to Ara Kharazian, economist at Ramp, the decline is explained by falling prices for top-tier models and the rise of cheaper standard models, mainly driven by competition between OpenAI and Anthropic. These two players account for most token spending (51% for Anthropic, 44.5% for OpenAI at the end of September), while open-source models represent less than 5% of spending.
