Anthropic’s recent S-1 filing on October 26 has accelerated IPO momentum by detailing first-half 2026 revenue of $16.3 billion—up more than 1,300 percent year-over-year—with Q2 alone exceeding $11.6 billion and an initial operating profit. The filing underscores $80.7 billion in net losses, largely non-cash adjustments tied to convertible notes as private valuation climbed to $965 billion in May, alongside $500-plus billion in committed compute spending and substantial cash reserves near $132 billion. Nasdaq listing under ticker “ANT” is targeted for mid-November, positioning the deal as a potential record raise near $1.5–2 trillion amid hyperscaler backing from Amazon and Google. Traders are weighing sustained revenue acceleration against infrastructure costs, regulatory scrutiny, and founder-controlled governance as the primary swing factors ahead of the roadshow.
