Analyst: Anthropic left Sept ARR blank; strong Oct data to follow in amended S-1

firstadopter · x · 2026-10-26

Finance analyst firstadopter speculates Anthropic left September quarter ARR blank in its S-1 due to stiffer competition from OpenAI's better offerings. He expects October ARR to be very strong following the Sept. 22 release of Opus 5.5, which should help the IPO — hence October figures will be filed in an amended S-1. He also predicts this will be the last time ARR is ever reported as a KPI.
