ASML stock climbed 116.8% over one year, driven by a wave of hyperscaler capital commitments that flow downstream into chip fabrication demand.1
Microsoft signed a 5-year AI data center capacity deal with IREN, a move that anchors long-term infrastructure spending commitments.1 IREN launched a $6 billion equity program to fund the expansion required under the agreement.1
Amazon separately announced its 2026 capital expenditure plan and made a direct investment in Anthropic, the AI safety company.1 Both moves signal Amazon's strategy: fund model development and the infrastructure to run it simultaneously.
The pattern is consistent across both companies. Amazon and Microsoft are not making one-time infrastructure purchases. They are structuring multi-year commitments that create predictable, compounding demand across the supply chain.
ASML sits at the end of that chain. The company holds a monopoly position in extreme ultraviolet (EUV) lithography equipment — the machines required to manufacture the most advanced AI chips.1 No alternative supplier exists at EUV scale.
The lag between hyperscaler capex announcements and ASML order backlog growth runs roughly two to four quarters. Data center deals trigger chip orders. Chip orders drive fab expansions. Fab expansions require EUV tools. That sequence takes time to move through the supply chain.
Analyst sentiment around chip demand feeds directly into ASML's market valuation, according to market research cited in semiconductor coverage.1 The stock's 116.8% gain reflects the market pricing in that durable demand signal ahead of backlog confirmation.
For investors, the structure of these deals matters as much as the dollar amounts. A 5-year data center agreement is not a capex line item — it is a demand guarantee. Microsoft's deal with IREN and Amazon's 2026 capex commitments create visibility that single-year budgets do not.
The risk is concentration. Both Amazon and Microsoft are making large, illiquid bets on AI infrastructure scaling at a specific moment. If model demand plateaus or efficiency gains reduce compute requirements, multi-year capacity contracts become liabilities rather than assets.
For now, the capital is moving. ASML's stock performance suggests markets believe the demand signal is real and will persist through multiple equipment upgrade cycles.
