Key Notes
- Anthropic’s reported $100 billion IPO target could exceed SpaceX’s approximately $86.3 billion gross offering, but official pricing and size remain unset.
- The Claude developer disclosed SpaceXAI computing agreements worth up to $120.5 billion through 2029, with delivery conditions and cancellation rights.
- The agreement covers access to NVIDIA-powered capacity rather than a direct $120.5 billion payment to NVIDIA or an immediate use of IPO proceeds.
Anthropic’s reported ambition to raise as much as $100 billion at a valuation near $2 trillion could produce an IPO larger than SpaceX’s record-setting June offering. The comparison now has an additional dimension: the Claude developer’s filing discloses computing agreements with SpaceXAI worth up to $120.5 billion.
International Financing Review reported the potential $100 billion raise and $2 trillion valuation as targets. Anthropic’s October 26 announcement confirms its public S-1 filing and proposed Nasdaq ticker ANT, but leaves the number of shares and price range undecided.
That means Anthropic has not officially fixed either a $100 billion offering or a $2 trillion market value. It has also not announced a first trading date. We reported separately on the newly filed prospectus, its financial results and risk disclosures.
SpaceX’s Completed IPO Sets the Benchmark
SpaceX (NASDAQ: SPCX) priced its June offering at $135 a share. Its pricing announcement covered 555,555,555 shares, equivalent to approximately $75 billion before the underwriters’ additional-share option.
The full option brought the total to 638,888,888 shares. At the offer price, that represents approximately $86.25 billion in gross proceeds, commonly rounded to $86.3 billion. SpaceX’s September-quarter 10-Q reports $85.675 billion in net IPO proceeds after $575 million in underwriting commissions and offering costs.
The distinction matters when measuring a record. Comparing a proposed gross raise with another company’s proceeds after fees would overstate the difference. Against the approximately $86.25 billion gross benchmark, a $100 billion Anthropic transaction would be about $13.75 billion, or 16%, larger.
That remains a conditional comparison. Anthropic would have to price and complete an offering of that size before it could claim the record.
A $2 Trillion Valuation Is Different From $100 Billion Raised
The valuation describes the equity value assigned to the whole company. Offering proceeds describe the amount investors pay for the shares sold in a particular transaction. Those amounts do not measure the same thing.
A $100 billion sale at a $2 trillion equity value would represent roughly 5% of that value, before considering the actual capital structure and transaction terms. That arithmetic is an illustration, rather than an ownership percentage disclosed by Anthropic.
The prospectus also contemplates sales by both the company and existing shareholders. Proceeds from secondary shares would go to their sellers. The final documents are needed to establish how much new capital Anthropic itself would receive, as well as dilution and ownership after the IPO.
SpaceXAI Agreements Link the Two Companies Commercially
Anthropic’s S-1 says agreements entered into and amended between May and October cover access to computing powered by NVIDIA GPUs. The counterparty is SpaceX.AI LLC, formerly X.AI LLC, a wholly owned SpaceX subsidiary.
The disclosed maximum is $120.5 billion over terms extending into 2029. Once all capacity is delivered, Anthropic expects aggregate fees of approximately $3.1 billion a month, with full delivery anticipated in December 2026 and different charges during the ramp-up.
The cancellation provisions are important. After initial non-cancelable periods ending in January and March 2027 under the respective agreements, either party may cancel with 90 days’ advance written notice.
The $120.5 billion figure therefore describes an agreement ceiling with specified timing and termination rights. It is not a payment already made, an unconditional bill due immediately, or an announcement that Anthropic will transfer its entire IPO proceeds to SpaceX.
NVIDIA Supplies the Technology Behind the Capacity
The agreements connect Anthropic’s model business with SpaceX’s computing infrastructure and NVIDIA’s accelerators. They do not establish that NVIDIA Corp. (NASDAQ: NVDA) directly receives $120.5 billion from Anthropic.
For SpaceX investors, a large customer agreement can support demand for deployed capacity. The associated revenue still depends on capacity delivery, contract performance and the customer’s use of its cancellation rights. A contract maximum should not be treated as guaranteed revenue already earned.
The relationship also sits alongside SpaceX’s own financing needs. We previously reported Musk’s statement that SpaceX had closed a $40 billion AI-chip debt deal. That borrowing and Anthropic’s potential share offering are separate transactions.
Public Investors Will Price Growth Against Financial Obligations
Anthropic’s first-half figures show both the appeal and the difficulty of the investment case: $16.286 billion in revenue alongside an $80.748 billion net loss, including $72.388 billion in financing-related fair-value charges. The accounting loss is not an equivalent measure of cash spent operating Claude.
For prospective ANT shareholders, the next test is the actual offer price and capital raised against the company’s computing requirements. For SPCX shareholders, the question includes the return on the infrastructure supplied to customers such as Anthropic.
The reported $100 billion ambition would set a new IPO benchmark if completed. Until pricing establishes the terms, the stronger evidence is the public filing, the completed SpaceX transaction and the commercial agreements connecting the two businesses.
