Anthropic estimates its market opportunity at over $30 trillion, according to the Wall Street Journal – more than SpaceX cited before its own IPO in June. Anthropic aims to raise up to $100 billion in its planned IPO at a valuation of around $2 trillion. The prospectus is expected to follow soon, with a debut possible as early as September.
Revenue rate jumps from $9 billion to $65 billion
The basis for the market estimate is Anthropic’s rapid revenue growth. The annualized revenue rate reportedly rose from around $9 billion at the end of 2025 to $65 billion by the end of July 2026 – nearly sevenfold within a few months. Just the day before, six investors had projected a valuation of at least $2 trillion for the October IPO; the newly disclosed, independently unverified $30 trillion market estimate now supplies the justification Anthropic is pitching to investors. For the second quarter of 2026, the company reported revenue of $11.6 billion, more than double the same quarter a year earlier. Anthropic is following a familiar IPO playbook: SpaceX also touted a $28.5 trillion market opportunity before its own June listing, raising $86 billion at a $1.77 trillion valuation. SpaceX’s stock has since fallen from its $135 issue price to below $105 in August – a sign of how hard lofty market estimates are to sustain over time.
Analysts call the $30 trillion estimate exaggerated
Anthropic calculates the $30 trillion figure as a so-called Total Addressable Market, or TAM – the theoretical maximum market size if a company could capture every task that AI models could ever perform. NYU finance professor Aswath Damodaran already described a comparable TAM estimate from SpaceX as “reaching the end of what’s plausible and pushing beyond.” For comparison, the 191 technology companies in the S&P 1500 index generated a combined $2.4 trillion in revenue last year – less than a tenth of the figure Anthropic is touting. Earlier IPOs used the same TAM logic to justify long investment horizons: Uber pegged its market potential at $6 trillion before its 2019 IPO, while the later-scrapped WeWork offering cited $3 trillion. Not every investment banker shares the skepticism: Jim Neesen of the Connor Group, which says it has advised on more than 275 IPOs worth over $4 trillion combined, calls the metric reasonable because it captures the real opportunity behind the business.
IPO market posts its best half-year in years
Anthropic’s plans land in an unusually active year for stock offerings. US IPOs raised a combined $114.2 billion in the first half of 2026 across 65 listings, up from $14.8 billion across 34 IPOs in the first half of 2025. The second quarter of 2026 alone brought in $114.1 billion. OpenAI is also reportedly preparing its own IPO, intensifying competition for investor capital across the industry and adding to the time pressure on Anthropic. At the same time, the heavy capital needs of data centers are shaping the timeline: just in August, Google tied $200 billion in loans to chip deliveries Anthropic is leasing to fill out its data centers. If the IPO goes as planned, Anthropic’s $2 trillion valuation would surpass SpaceX’s prior record of $1.77 trillion, making it the largest-ever IPO of an AI company that isn’t yet consistently profitable. That would place Anthropic among the world’s most valuable companies, a group currently led by tech giants such as Apple, Nvidia and Microsoft.
What will matter is whether Anthropic can turn the back-of-envelope math from investor conversations into audited figures for the formal SEC filing an IPO in September or October would require. So far, every figure – from the revenue rate to the market estimate – comes from people who themselves stand to gain from the listing’s outcome; independent verification is still pending.
