Anthropic’s annualized revenue run rate tops $80 billion as IPO plans shift
Anthropic's annualized revenue run rate topped $80 billion in October, even as its IPO may raise less money and arrive later than expected.
The Claude maker's revenue keeps climbing, but its public offering may raise less money and arrive later than expected. The timing creates an unusual juxtaposition of record growth against a cooling listing.
By October 2026, Anthropic's annualized revenue run rate reached $80 billion, a figure most public companies never see in total annual sales, let alone as a run rate. This represents a significant jump from approximately $65 billion by late July 2026.
Explosive growth metrics
The company's S-1 registration statement, made public on October 26, 2026, revealed H1 2026 revenue of $16.3 billion, up from $1.16 billion in H1 2025. That works out to growth of more than 1,300% year-over-year.
Q3 2026 revenue is reported at between $16.8 and $17 billion, meaning a single quarter now brings in more than the entire first half of the year did. However, profitability remains complicated.
Anthropic reported its first operating profit in Q2 2026, amounting to $974 million, but also booked a net loss of $80.7 billion for H1 2026, driven largely by non-cash charges tied to convertible notes.
IPO valuation shifts
Anthropic filed confidentially for its IPO in June 2026 before going public with the S-1 in October. The anticipated listing is on Nasdaq under the ticker 'ANT.'
Valuation expectations have come down from early speculation of $2 trillion to around $1.5 trillion as investors grow cautious about tech selloffs and geopolitical issues. This would still leave Anthropic well above its private valuation of $965 billion in May 2026.
The debut might occur as soon as mid-November 2026, after the US midterm elections. The latest update, however, says the offering may be delayed.
Infrastructure costs and growth concerns
Anthropic has committed nearly $895 billion in infrastructure deals, primarily with Amazon, Google, and Microsoft. These long-term compute commitments dwarf even the company's most optimistic revenue projections.
The company has signaled that its previously rapid expansion rates may not be sustainable. Revenue growth has already eased from earlier triple-digit quarterly increases, with analysts tempering full-year projections to a range of $70 billion to $100 billion.
For investors, three factors matter most: whether the run rate holds after October, how the market digests the massive compute bill against moderating growth, and whether the Q2 2026 operating profit was a one-off. The timing of the offering itself will send signals about demand for high-risk tech listings.
