The document that moved markets Tuesday was not an earnings release. It was not a central bank statement. It was the confidential IPO prospectus of a private AI company, and within hours of Reuters publishing its numbers, semiconductor stocks from Amsterdam to Frankfurt were rallying on the strength of its purchase orders.
That is the fact portfolio managers will be arguing about this week: European semiconductor shares rose, led by X-Fab Silicon Foundries, on reports that Anthropic’s IPO prospectus pointed to a sharp increase in spending on cloud, computing and infrastructure, with the prospectus forecasting $518 billion in such obligations and bolstering sentiment across Europe’s semiconductor sector. In Germany, Infineon Technologies rose 4.8% and Aixtron gained 4.3%, while Amsterdam-listed ASML Holding rose 4.18% and ASM International gained 4.24%. A private company’s forward commitments, disclosed in a document not yet filed publicly with the SEC, reset a continent’s worth of publicly traded chip stocks in a single session.
The Big Question
Is Anthropic’s $518 billion compute obligation a signal that AI infrastructure spending is durable and still accelerating, or is it evidence that the economics of frontier AI have become untethered from anything resembling a conventional business model?
Revenue grew 12-fold in 2025 to nearly $4.6 billion, even as the company lost more than $8 billion on an operating basis, excluding writedowns of various liabilities mostly tied to previous fundraising. The near-$42 billion net loss included a roughly $34 billion accounting charge that reflected an increase in the estimated value of financing that could eventually turn into Anthropic shares, rather than money the company spent running its business. That distinction matters. The operating hole is real. The headline number is largely an accounting artifact of Anthropic’s own rising valuation.
What the Commitments Actually Say
Anthropic has committed $111.1 billion to Google, $110 billion to Amazon, $31.4 billion to Microsoft, $161.2 billion in Broadcom equipment lease obligations, up to $84.5 billion to xAI for Nvidia-based chips, and more than $20 billion in AMD compute capacity. About 80% of that sum is non-cancelable or payable regardless of usage. The contracts carry make-whole provisions: “If our actual spend falls short, we must pay Google the difference,” the company said, adding that similar terms apply to its Amazon agreement.
This is not capex optionality. It is a locked obligation schedule, and it runs for a decade.
Why the Chip Sector Responded
Chip investors remain focused on AI infrastructure rather than only on the profitability of individual model developers. Every expansion in model training, cloud capacity, and enterprise deployment requires additional processors, networking systems, memory, testing equipment and manufacturing tools. That spending flows through a wide industrial ecosystem, including companies that may benefit regardless of which AI laboratory ultimately becomes the dominant platform.
Anthropic’s disclosed $518 billion AI infrastructure plan signals multi-year capex intensity, which directly supports EUV and advanced lithography demand and the broader tooling cycle across leading-edge nodes. Equipment lead times mean today’s AI spend plans translate into future orders for ASML’s installed-base upgrades and new systems. AI data centers drive power electronics and efficiency upgrades; Infineon is positioned to benefit from the power-per-rack arms race that follows every wave of AI infrastructure build.
What Investors Are Missing
The debate is framed around whether Anthropic deserves a $2 trillion valuation. That is the wrong question for anyone sitting outside the IPO allocation. The more consequential question is what this prospectus confirms about the companies already public and already receiving these payments.
Broadcom secured multi-year AI infrastructure supply commitments from Anthropic, and management has outlined projections for AI semiconductor revenue of more than $56 billion for fiscal 2026 and over $100 billion for fiscal 2027. Amazon holds a minority stake in Anthropic and has received more than $100 billion in AWS cloud commitments from the company over the next decade, encompassing both Trainium AI accelerators and Graviton CPUs. These are not speculative demand signals. They are contracted revenue streams now visible in a prospectus.
Stocks to Watch
Broadcom (AVGO) is the single largest dollar recipient in the Anthropic commitment schedule, with $161.2 billion in largely non-cancelable equipment lease obligations.
ASML (ASML) does not sell chips to Anthropic directly. It sells the machines that make the chips Anthropic buys. When investors raise their estimates for future data-center and computing demand, the effect can spread quickly across equipment makers and component suppliers. Tuesday’s move reflects that transmission mechanism, not a completed order.
Amazon (AMZN) sits on both sides of this trade: investor, cloud supplier, and competing model developer. Anthropic told prospective investors that access to computing power is becoming a central constraint on AI development, with future demand expected to exceed available supply. AWS is the primary beneficiary if that view is correct.
Nvidia (NVDA) is reportedly weighing a $10 billion anchor stake in the IPO itself, having already covered 1 gigawatt of compute on Nvidia’s Grace Blackwell and Vera Rubin systems. Buying into the IPO locks the commercial relationship tighter.
