Anthropic’s share sale of up to $64 billion comes with a $900 billion compute bill

Anthropic has put a price on the first share sale by a company built entirely on artificial intelligence, and its paperwork carries a figure far larger than the sum it hopes to raise: the amount the Claude maker has already promised to spend on chips, data centres and the power to run them.

That gap is why the listing matters beyond Wall Street. The money flows straight into a construction boom that strains electricity grids, shapes what businesses pay for AI tools and decides which suppliers thrive. Savers who buy in, directly or through funds, are asked to back that bet with little say over how the company is run.

In an updated filing with the Securities and Exchange Commission, Anthropic said it will sell 825 million shares at between $70 and $78 each on the Nasdaq Global Select Market under the ticker ANT. About 801 million are new shares. The rest come from existing holders, including the seven co-founders, who are each selling roughly $260 million worth, according to the Guardian. At the top of the range the offering raises about $64.4 billion. Google, Nvidia, AMD, Broadcom, Micron, Microsoft and a TSMC affiliate have separately agreed to buy $26 billion of stock at the IPO price, and an option for the underwriters could add close to $10 billion more.

Revenue that grew thirteenfold, and a bill that dwarfs it

By the Guardian’s calculation, the top of the range values Anthropic at about $1.4 trillion on a fully diluted basis, below the roughly $2 trillion that had been talked about before AI stocks sold off. Revenue reached $33.2 billion in the nine months to September, up from $2.5 billion a year earlier, and the operating loss narrowed to $1.26 billion from $5.2 billion. The company puts its annualized run-rate at about $81 billion as of October 31.

Then there is the bill. Anthropic has signed purchase commitments and leases worth about $900.9 billion, almost all of it for compute and infrastructure. Roughly $70.7 billion falls due in the twelve months after September, some $451.6 billion before the end of 2030, and the remainder stretches to 2045. Compute already cost $18.8 billion in the first nine months of the year, more than half of revenue.

Three numbers that need a second look

The headline net loss of $104 billion overstates the cash burn: $94.3 billion of it comes from marking convertible notes and similar instruments to a rising valuation. The commitments are the harder obligation, because many carry take-or-pay terms that bind Anthropic to pay whether or not demand arrives. The run-rate metric multiplies the latest 28 days of usage fees by thirteen, which flatters a company in a growth spurt. And most of the seven buyers of that $26 billion sit in Anthropic’s own supply chain for chips, memory and cloud capacity, so part of the money raised circles back to the firms selling it computing power.

Public buyers also get limited control. Anthropic is a public benefit corporation. A Long-Term Benefit Trust elects a majority of its board through a special class of shares, and a founders’ vehicle holding a single share carries 50.1% of the vote on most other matters, which makes it a controlled company under Nasdaq rules. Fiona Cincotta, a senior market analyst at City Index, told Reuters the size of the raise was “fairly bullish” given recent volatility. For rival labs still private, including OpenAI, the price the market settles on becomes the yardstick for their next funding round.

The listing is in New York only, so investors in Europe and Asia will reach it through brokers that trade US shares. Goldman Sachs and Morgan Stanley lead the offering, and trading is expected to begin on November 19, according to the BBC and people familiar with the timetable cited by CNBC. Goldman forecasts annual revenue of $600 billion by 2030, the Financial Times reported.

Before any of that is tested, the figure to watch is the $70.7 billion of computing bills due within a year, larger than the entire base offering at the top of its price range.
