Anthropic, SpaceX and Wall Street’s trillion-dollar question

Wall Street’s appetite for technological ambition is approaching unprecedented territory. In June, Elon Musk’s SpaceX raised $75 billion in the largest initial public offering in history, securing a valuation of approximately $1.75 trillion. Four months later, artificial intelligence developer Anthropic is preparing a listing that could surpass it, with prospective investors assigning the company a value of around $1.5 trillion.

Despite operating in different markets, both companies command valuations based partly on anticipated dominance in industries whose commercial potential remains uncertain. SpaceX is betting on satellite communications, space infrastructure, and artificial intelligence, while Anthropic is competing to supply the advanced AI systems expected to transform economic activity.

Their offerings arrive amid an investment surge, with J.P. Morgan Global Research projecting $900 billion in worldwide AI capital expenditure in 2026 alone, amid concerns over profitability and financing costs. As Amazon, Microsoft, Alphabet and other technology giants commit unprecedented sums to AI, rising financing requirements and uncertain returns, analysts warn, are placing greater pressure on valuations.

The price of future dominance

SpaceX's June debut demonstrated how far investors were prepared to go in pricing technological ambition. The company sold 555.6 million shares at $135 each, raising $75 billion and more than doubling the previous IPO fundraising record held by Saudi Aramco. Shares closed their first day at $160.95, valuing SpaceX at $2.1 trillion, before declining to $147.49 by Oct. 23, according to historical market data.

Anthropic must now convince investors that its rapid revenue growth can support a similarly extraordinary valuation, despite substantial operating costs and uncertainty over future demand.

According to the company's Form S-1 registration statement–a financial disclosure filed with the U.S. Securities and Exchange Commission on Oct. 26, 2026–Anthropic generated approximately $16.3 billion in revenue during the first half of 2026, compared with $1.2 billion during the corresponding period a year earlier. Its operating loss narrowed from $2.1 billion to $693 million.

The 335-page filing, known as an IPO prospectus, also confirms Anthropic's plans to list on the Nasdaq under the ticker symbol ANT, although the offering price and number of shares remain undetermined.

The economics behind the ambition

Both companies face enormous investment requirements relative to their anticipated earnings.

Anthropic's October 2026 prospectus disclosed commitments exceeding $600 billion for computing infrastructure through arrangements with partners including Amazon and Google. Computing expenses are expected to rise and remain its largest operating cost.

Its reported first-half net loss of $80.7 billion also requires careful interpretation, analysts say. Most of that loss came from an accounting charge tied to financing arrangements that can convert into company shares, rather than money spent directly on developing and operating its AI services.

Anthropic's operating losses have therefore narrowed considerably, even as its long-term financial commitments have expanded.

The scale of the industry's investment requirements is equally striking. J.P. Morgan Global Research projected in October 2026 that cumulative worldwide AI capital expenditure could reach $5.5 trillion by 2030.

Such commitments carry considerable financial risk, particularly as returns may take years to materialize. Advanced computing equipment can also lose economic value rapidly as newer processors become available, shortening the period in which companies can recover their investments and generate profits.

Wall Street's financing dilemma

The financial pressures surrounding these companies are emerging alongside a significant change in how technological expansion is financed.

According to J.P. Morgan, major cloud computing companies initially funded much of their AI investment through internally generated cash. Now, companies including Alphabet and Oracle are raising additional money by borrowing from investors and selling shares, increasing their dependence on financial markets to fund infrastructure expansion.

The distinction carries consequences for financial markets worldwide. Greater reliance on external financing exposes technology investment to borrowing costs and changing investor sentiment.

It also raises the stakes for Anthropic's forthcoming listing.

Unlike SpaceX, whose established Starlink business generates revenue from satellite connectivity, Anthropic depends on the continued commercial adoption of AI systems in a market characterized by intense competition and rapid technological change.

Both companies must convince investors that their competitive advantages will endure long enough to produce returns commensurate with their valuations.

The implications also reach emerging economies seeking investment in digital infrastructure. J.P. Morgan identifies expanding data center activity across Southeast Asia, Latin America, Africa and the Middle East, alongside growing constraints involving electricity availability, equipment supplies and construction costs.

The profitability of the AI investment boom therefore depends partly on physical infrastructure, energy systems and financing conditions far removed from Silicon Valley.

Innovation or speculation?

Extraordinary valuations are not inherently evidence of speculative excess. Companies introducing transformative technologies can generate returns that conventional financial projections struggle to anticipate, particularly when their products create entirely new markets.

SpaceX has already demonstrated substantial commercial demand for satellite communications, while Anthropic's rapid revenue expansion indicates that businesses are willing to pay for advanced AI services.

Nevertheless, the valuations attached to both companies leave relatively little room for disappointing growth, intensifying competition or unexpectedly high costs. Anthropic's IPO will provide another indication of how much uncertainty investors are prepared to accept in exchange for exposure to technological innovation.

Rising financing requirements are increasing the pressure on companies to demonstrate sustainable earnings and cash generation, strategists caution. For investors assigning trillion-dollar valuations to businesses still pursuing their greatest commercial ambitions, the challenge is determining how much future growth has already been priced into today's shares, and how much remains to be earned.
