Anthropic IPO: Here's What a $5,000 Investment Could Be Worth in 5 Years

One of the most eagerly awaited stock market launches in history could happen soon.

Anthropic, the company that makes the Claude family of large language models (LLMs), is getting ready to sell shares to the public. Its stock market debut could be the biggest ever, even larger than the record-setting Space Exploration Technologies (SPCX +7.80%) IPO just a few months ago.

The company has not set an exact date, but it is expected to go public next month. It is aiming for a company value between $1.5 trillion and $2 trillion.

Investors are excited and eager to buy shares because Anthropic is at the leading edge of artificial intelligence and is growing at a speed rarely seen in a company of this size.

So, if the company reaches the $2 trillion value its leaders are seeking when it goes public, how much could a $5,000 investment be worth five years later?

What you're actually buying with Anthropic stock

Here is how Anthropic makes money: It builds Claude AI models and chatbots and sells people access to them. Many individuals pay monthly subscription fees, but most of Anthropic's income comes from businesses. Technology companies, in particular, now use Claude Code to help their developers write computer code. So far, this has been Anthropic's biggest source of income.

According to Reuters, which reviewed the company's draft IPO prospectus, Anthropic made about $4.6 billion in sales in 2025, roughly 12 times what it made in 2024. But its sales have grown much faster in 2026. Last week, Reuters reported that the company's revenue in the third quarter reached $16.8 billion, up 45% from the second quarter.

However, this fast growth came with huge costs. Anthropic spent $7.33 billion on computing power and infrastructure alone in 2025. This helped lead to an operating loss of more than $8 billion. The company also reported a huge net loss of $42 billion. However, about $34 billion of that loss came from an accounting adjustment and did not show how profitable the business was from its actual operations.

Reports say Anthropic made a positive adjusted profit in the second quarter of 2026. This is an encouraging sign, but it is not clear exactly what the company counted as an "adjusted" profit. The difference between this figure and profit calculated under generally accepted accounting principles (GAAP) is very important. It matters which real business costs the company's leaders leave out when working out this adjusted profit.

What $5,000 could be worth in five years

If Anthropic were worth $2 trillion on the stock market, its shares would be priced at more than 400 times its 2025 revenue. But the price would be about 30 times its third-quarter revenue multiplied by four to estimate a full year's revenue. This is still a very high price, but it is within a range that could make sense.

The optimistic case for the stock depends on several things. Demand for Claude must keep growing quickly over the next few years, especially among large business customers. Anthropic must remain a clear leader, and its language models must continue to offer some of the most advanced AI abilities available. The cost of serving customers must also fall considerably, and the company's profit margins must improve until the business can truly make a profit.

The middle case assumes Claude remains one of the leading models, but its growth slows somewhat as businesses choose cheaper competing models that can still do the job. Demand for Claude outside the coding market exists, but does not grow as much as the company might hope. Its losses become somewhat smaller, but it still spends much more money than it brings in.

Finally, the pessimistic case assumes that people continue to want language models, but Anthropic's growth slows sharply. The company must compete with capable rivals on price while customers become more careful about spending. The cost of running its language models does not fall much, and the company continues to use up the cash it receives.

Here are my estimates of how Anthropic's yearly revenue and price-to-sales ratio could change over the next five years under these three scenarios. Each scenario assumes you invest $5,000 in Anthropic when its stock market value is $2 trillion. It also assumes the company does not issue more shares later in a way that reduces your ownership percentage.

Why I'm skeptical of the bull case

The optimistic case depends on two ideas that, in my view, do not fit well together. If Anthropic wants to keep Claude models far ahead of its competitors so customers will continue paying full price, it will not be able to slow the training of new models very much. Continuing to spend so much on training will leave the company with much less room to improve its profit margins, and I cannot see how it could ever break even.

In fact, I think even the base case is too optimistic. I believe a more pessimistic outcome is more likely five years from now, as AI becomes a product that many companies can offer at similar levels of quality.

The bottom line on the Anthropic IPO

Of course, this pessimistic view is my opinion. Many analysts would argue that the optimistic case is a likely outcome.

The value of a $5,000 investment made in Anthropic near the start of its life as a publicly traded company could look very different five years later. The result depends on many factors that are hard to predict. That is what makes investing in fast-growing companies with high prices compared with their sales, especially in new industries, so uncertain. Their futures are much harder to predict, and the possible outcomes can be very different.
