Anthropic's IPO Math Needs an Extraordinary 2028
Matthew Leo · Published August 16, 2026 · Business & Policy
Anthropic's prospective IPO is asking investors to value a company that does not exist yet: the much larger business management expects to have in 2028.
Reuters reported on August 15 that Anthropic is projecting roughly US$190 billion to US$200 billion in 2028 revenue, according to two people familiar with its finances. Bankers and investors are reportedly using those future sales to help establish a possible IPO valuation.
Anthropic did not confirm the figures to Reuters. They should be treated as a reported internal forecast, not audited guidance or a promise to public shareholders.
The forecast requires another sharp acceleration
Anthropic said in May that its revenue run rate had passed US$47 billion. A run rate annualizes a recent period; it is not the same as revenue already earned during a complete year. Even using that favourable starting point, reaching the midpoint of the reported 2028 range would require sales to grow about 4.15 times.
If the change occurred over two full years, that works out to roughly 104 per cent compound annual growth. The precise rate depends on the starting date and whether the run rate holds, but the scale is clear: Anthropic would need to more than double the business in each of the next two years.
| Measure | Approximate value |
|---|---|
| May 2026 reported revenue run rate | More than US$47 billion |
| Reported 2028 forecast range | US$190–200 billion |
| Growth to midpoint | About 4.15 times |
| Illustrative two-year annual growth | About 104% |
| US$2-trillion value at midpoint revenue | About 10.3 times 2028 sales |
The last row is not an IPO price prediction. Reuters quoted one investor asking whether Anthropic could reach a US$2-trillion valuation, so the calculation shows what that figure would represent against the reported forecast.
Revenue is only half the model
Fast sales growth can coexist with poor economics. Anthropic pays for chips, data-centre capacity, model training, inference and highly compensated staff. The IPO case assumes those costs will become a smaller share of revenue as the company scales.
That may happen. New hardware, model efficiencies and higher utilization can reduce the cost of answering each request. The opposite risks are equally real: customers may demand lower prices, competitors may match capabilities, electricity and chip capacity may stay expensive, and a new training cycle may consume the savings from the last one.
A useful prospectus would separate gross margin by major product class, committed cloud spending, customer concentration and the cost of serving long-context or agentic workloads. A single revenue number cannot show whether the next dollar is profitable.
Forecast quality matters more than forecast size
Investors should ask how the 2028 range was built. Does it depend on signed contracts, expansion by existing customers or markets Anthropic has not entered? How much assumes price stability? How much revenue comes from related cloud partners that also finance the underlying infrastructure?
The sensitivity table should be as prominent as the optimistic case.
- What happens if annual growth falls to 60 per cent?
- How does valuation change if gross margins stop improving?
- How much computing capacity is contractually committed?
- Can a small group of customers materially move the forecast?
- What regulatory or copyright liabilities are excluded?
Looking two years forward is not automatically improper. Young companies are often valued on the business they are becoming. It does increase the number of assumptions between today's evidence and the price an investor pays.
Canadian investors may meet the risk indirectly
Most Canadians will not receive a special allocation in a major U.S. IPO. Exposure can still arrive through technology funds, broad U.S. indexes, pension portfolios or financial institutions that buy after listing.
That makes the valuation method relevant even to someone who never places an order for Anthropic shares. An index fund can add a richly valued company after eligibility requirements are met, while an actively managed fund may treat the listing as unavoidable exposure to artificial intelligence.
Canadian investors should check whether a fund discloses its largest positions, concentration limits and currency hedging. The presence of a fashionable company does not change the role the investment is supposed to play in a retirement portfolio.
The prospectus must replace the narrative
Reuters' report provides an early look at how bankers may frame the deal. The formal registration documents, if Anthropic files them, should carry more weight. They can reveal audited revenue, losses, related-party arrangements, contractual obligations and risk factors that a reported forecast cannot.
Investors should also compare the forecast with later quarterly results instead of treating it as a fixed destination. A company growing this quickly can beat one period and still fall behind the multi-year path required by its valuation.
Anthropic may reach or exceed US$200 billion in 2028 sales. Its recent growth has already been exceptional. An extraordinary forecast still deserves ordinary financial discipline.
The cleanest question is not whether artificial intelligence will become a large market. It is how much of Anthropic's future success has already been included in the price before public investors get a chance to buy.
