Anthropic Files for IPO as 'ANT': $16.3B Revenue Sparks a Global Chip Rally

Anthropic publicly filed for an initial public offering on Monday, October 26, 2026, planning to list on the Nasdaq Global Select Market under the ticker "ANT" — and markets moved immediately. US chip stocks rallied Monday, then South Korea's KOSPI surged more than 4% and Japan's Nikkei 225 rose 1.9% in early trading on Tuesday, October 27 in Asia, as investors treated the Claude maker's filing as a fresh vote of confidence in the AI trade.

What happened, in brief

Anthropic, the company behind the Claude chatbot, made its Form S-1 public after confidentially filing in June. The filing gives public investors their first detailed look at a frontier AI lab's finances: revenue of $16.29 billion in the first half of 2026, up about 1,304% from $1.16 billion a year earlier, alongside a net loss of about $80.7 billion for the same six months. Goldman Sachs and Morgan Stanley are leading an offering handled by 22 banks, according to reports on the filing. No share count, price range or offering size has been disclosed yet.

Why the loss figure needs context

The headline loss is not mostly cash burned on operations. Reporting on the prospectus says about $72.4 billion of the $80.7 billion net loss was a non-cash charge tied to the rising value of convertible notes and related agreements, and the operating loss for the half was about $693 million. In the second quarter alone, revenue reached about $11.6 billion and the company posted its first operating profit on that measure, about $974 million. Anthropic also said customers paying more than $100,000 a year grew from more than 950 to more than 11,900 in twelve months. The company has raised about $141 billion and held about $112.4 billion in cash, according to the filing reports.

Why it's blowing up

Two numbers explain the reaction. First, the growth: $16.3 billion in six months, after $4.6 billion in all of 2025, tells investors AI model demand is still expanding at extraordinary speed. Second, the spending: the filing details compute commitments above $400 billion in total — including at least $110 billion with Amazon, about $114.5 billion with Google, about $45 billion with Microsoft, up to about $120.5 billion involving SpaceX, and about $161.2 billion in Broadcom equipment leases. A separate financing arranged for chips destined for Anthropic, reported at $63 billion with Bank of America, Blackstone, Citigroup and Morgan Stanley, underlined how much hardware spending sits behind the filing. That is why chipmakers, not just Anthropic watchers, rallied.

How markets reacted — US, then Asia

In the US on Monday, the S&P 500 gained 0.7% to 7,676.77, the Nasdaq Composite rose 0.82% to 26,169.38 and the Dow added 0.28% to 52,361.58. The Philadelphia Semiconductor Index jumped about 2.8% and the iShares Semiconductor ETF popped nearly 3%, with Nvidia up about 2.4%, Micron up about 3%, Broadcom up about 2.3% and AMD up about 2.8%.

Asia extended the move on Tuesday morning. Reuters reported the KOSPI gaining more than 4% in early trading and the Nikkei 1.9% higher, with MSCI's broadest Asia-Pacific index outside Japan up 1.2% and Nasdaq futures up 0.4%. TradingKey put the KOSPI at 5,701.01 points, up 4.23%, with Samsung Electronics up 4.93% to 223,500 won, SK hynix up 6.35% to 1,356,000 won, Kioxia up 7.85% and SoftBank up 5.98%, as the Nikkei stood at 63,373.34.

What's next

People familiar with the matter have told the Wall Street Journal the listing is aimed at the week of November 16, but that timetable is reported, not announced, and remains subject to change. Reports have also pointed to a possible valuation around $2 trillion — again, that is not a term in the initial filing. Before any debut, investors will get an amended filing with the blanks filled in: price range, share count and updated quarterly figures. This week adds two more tests: Alphabet and Microsoft earnings on Wednesday, Amazon on Thursday, and rate decisions from the Federal Reserve, the European Central Bank and the Bank of Japan, all expected by Reuters to hold rates steady. This article reports what happened and how markets reacted; it is not a recommendation to buy, sell or hold any security.
