Should You Buy the Anthropic IPO? Half-Year Revenue Beat Last Year’s Total by 3× — Check These 3 Risks First

Data as of: 2026-11-06. Revenue figures from Anthropic’s official announcement and SEC S-1; as of 11/6, the amended S-1 filed 11/2 still leaves the price range, share count and date blank. IPO details change quickly; rely on Anthropic’s and the SEC’s latest documents.

This short got 13,000 plays on Facebook. This post answers one question: should you rush into the Anthropic IPO?

The conclusion in three sentences:

• Growth is genuinely fast. First-half 2026 revenue was about US$16.3 billion, 3.5× full-year 2025 revenue of about US$4.6 billion.
• But the source of growth is also the source of risk. Usage-based pricing, multi-year compute contracts and suppliers who are also competitors need to be looked at together.
• The price isn’t set yet. A good company isn’t automatically a good stock; your purchase price matters too.

Where I stand: Anthropic isn’t listed yet, and I don’t hold its shares. My core holdings are 0050, the S&P 500 and QQQ.

Who is Anthropic, and where is the IPO?

Anthropic is the company that makes the AI assistant Claude.

• 2026-10-26: announced a public S-1 filing, planning to list on Nasdaq under ANT
• 2026-11-02: filed an amended S-1; the price range, share count and date are still blank

Filing to go public isn’t the same as being public. Until the price is out, it’s too early to call it cheap or expensive.

Why is revenue growing so fast?

First, clarify the numbers:

This is “half a year” vs “the previous full year” — not 3.54× year-over-year growth, and certainly not profit.

I think two things are key:

1. Enterprise customers. If a tool like Claude Code that helps write code really saves companies time, they’ll pay for it and let more employees use it.
2. Usage-based pricing. The more enterprises use it, the more Anthropic earns.

3 risks to check before buying

Risk 1: less usage means less revenue — but not necessarily smaller bills

Usage-based pricing cuts both ways. If customers use less next month, they pay less.

But Anthropic’s compute contracts may already be signed for years. Revenue can drop while the bills don’t, which hits profits directly.

Risk 2: suppliers are also competitors

Google, for example, sells compute to Anthropic while building its own AI. Anthropic effectively has to compete with its own supplier for customers.

Risk 3: growth priced in first

This is the most overlooked point with IPOs. If the next several years of growth are already reflected in the listing price, merely growing slower than expected can send the stock down. Revenue could keep rising while your shares don’t.

My view

Revenue growing this fast is impressive, of course.

But if you want to buy the stock, you have to look at what it has to pay, and the price you pay, together.

If you’re simply bullish on AI as an industry, you don’t have to bet on a single new listing. Index ETFs like QQQ and the S&P 500 already hold many large AI-related companies; and a new listing that’s big enough and meets the criteria may later be added to the index.
