ASML's roadmap to 1,000W EUV light sources could increase wafer output by 50% using existing installed base, fundamentally altering the capex-to-capacity equation that has driven semiconductor valuations since 2023. The company disclosed the upgrade path at a technical presentation, targeting implementation within the current generation of EUV systems. This matters because it decouples capacity expansion from the 18-24 month lead times and US$200m+ price tags of new tool installations.
The market has priced ASML on unit shipment growth, but throughput gains on ~1,000 installed EUV tools globally represent a stealth capacity multiplier. For leading-edge fabs already constrained by cleanroom space and power infrastructure, boosting output per tool by 50% is effectively a free capacity addition. TSMC and Samsung, which together account for over 70% of EUV tool installations, gain immediate operating leverage.
The technology also widens ASML's moat: rather than waiting for ASML's next-generation High-NA EUV tools (currently limited to Intel), customers can upgrade light sources on existing 0.33 NA systems. This extends the economic life of current-generation infrastructure and delays the need for High-NA adoption, buying time for the ecosystem to mature. For ASML, the services and upgrade revenue stream becomes more predictable and less cyclical than new tool sales.
Investor takeaway: ASML's installed base becomes a recurring revenue engine, not just a one-time capex event. The stock has lagged Nvidia year-to-date; this reprices the earnings durability story. (24 Feb 2026)

HBM4 supply is already sold out through 2026 before mass production has even begun, with Samsung and SK Hynix commanding 30%+ premiums over HBM3E, signaling memory's re-rating from cyclical commodity to AI infrastructure constraint. Micron reported February that HBM inventory is "depleted," while industry sources confirm Nvidia has locked multi-year offtake agreements with all three suppliers at prices that would have been unthinkable in prior memory cycles.
The shift is structural, not cyclical. AI accelerators are now memory-bound: Nvidia's GB200 systems pair two GPUs with 1.4TB of HBM3E, making memory 40-50% of chip content value versus <20% in prior server generations. TSMC's CoWoS advanced packaging capacity, the physical layer that integrates HBM with GPUs, is also sold out through 2027 despite aggressive expansion. The bottleneck has moved from logic to memory to packaging, and pricing power has followed.
But here's what the market is underestimating: HBM yields remain challenging, particularly for the next-generation 12-high and 16-high stacks required for future AI systems. Samsung's HBM4 qualification delays with Nvidia in late 2025 were yield-related, not design-related. SK Hynix has the current lead but Samsung is closing the gap, and Micron remains structurally subscale. This tight oligopoly, combined with 18-month qualification cycles and multi-billion dollar fab conversions, keeps supply constrained well into 2027.
The repricing is already visible in equity markets: Samsung Electro-Mechanics, which supplies memory substrates, surged 33.8% over the past week amid reports of expanded MSAP substrate orders for HBM4. The moves are confirmation that pricing power is real and durable. (24 Feb 2026)

Anthropic disclosed that three Chinese AI labs conducted "industrial-scale distillation" of its Claude models using 24,000 fraudulent accounts and 16 million API calls, the same week Reuters confirmed DeepSeek trained on Nvidia's H100 chips despite US export controls. The dual revelations expose how quickly export restrictions become obsolete when enforcement relies on declarative compliance rather than technical controls.
The distillation playbook is straightforward: flood a frontier model with queries, capture responses, then train a smaller "student" model to replicate outputs without needing the original training data or compute infrastructure. Anthropic's detection came from usage pattern analysis, not inherent technical barriers. The implication: model weights are the new IP battleground, and API access is a vector for competitive intelligence theft at scale.
More significant is the DeepSeek chip access story. A US official confirmed to Reuters that DeepSeek used Nvidia H100 GPUs for training, contradicting the narrative that China's AI labs are purely domestic-chip reliant. The chips likely flowed through third countries or shell procurement networks. For investors, this means two things: first, Nvidia's China revenue is structurally higher than reported (consensus models assume near-zero China sales post-restrictions); second, the technical gap between US and Chinese AI capabilities is narrower than policy assumes, raising the stakes for future restrictions.
The White House faces a credibility gap: export controls are politically visible but operationally porous, while calls to tighten restrictions (House proposals floated in February would ban all AI chip exports to China) risk backfire if enforcement remains weak. The semiconductor and AI supply chains are too globally integrated for unilateral controls to work as designed. (23-24 Feb 2026)

IBM shares plunged 13% on February 23, the largest single-day decline since 2000, after Anthropic introduced Claude Code tools specifically targeting COBOL and legacy system modernization, directly threatening IBM's US$20bn+ mainframe services annuity. The selloff reflects sudden consensus that generative AI is no longer a productivity tool for IBM's legacy business but an existential replacement technology.
The timing is brutal: IBM has positioned its mainframe and consulting franchises as AI beneficiaries, arguing that enterprises will use AI to optimize existing systems. Anthropic's demo flipped the script: instead of maintaining COBOL, Claude Code helps customers migrate off it entirely. The shift from "AI helps legacy" to "AI replaces legacy" reprices IBM's services durability. The stock is down 18% year-to-date; options markets now imply elevated volatility through earnings.
This is part of a broader pattern visible across the February 23 session: software stocks with large legacy installed bases sold off sharply (Accenture down despite announcing an OpenAI partnership, ServiceNow weak), while infrastructure plays (Nvidia, Broadcom, Dell) held steady. The market is actively sorting "AI winners" from "AI disrupted," and the line keeps moving. IBM's challenge is that its consulting revenue depends on complexity; AI tools that reduce complexity are deflationary to services demand.
The second-order effect: if large enterprises can modernize mainframes without multi-year IBM consulting engagements, the capex cycle for next-generation infrastructure (cloud, AI-native stacks) accelerates. This is bullish for hyperscalers and hardware vendors but bearish for systems integrators locked into legacy maintenance. (23 Feb 2026)

Taiwan's Taiex surged 3% to a fresh all-time high on February 24, with TSMC contributing nearly 600 points of the gain after advancing to NT$1,975, as investors priced in reduced tail risk from US-Taiwan trade negotiations. The move came despite a sharp selloff in US equities the prior session, signaling Taiwan's decoupling from broader tech weakness on confidence that semiconductor tariffs will remain minimal.
The catalyst was White House confirmation that countries with negotiated trade agreements, including Taiwan's pending Reciprocal Trade Agreement (ART), will face a uniform 15% tariff rate, not the higher Section 232 national security levies. Taiwan's government clarified that the ART process continues and that existing semiconductor tariff exemptions remain intact. For TSMC, which derives ~70% of revenue from US customers but manufactures primarily in Taiwan, tariff certainty removes a major overhang.
Broader Taiwan tech names rallied in sympathy: Accton Technology rose 18.1% over the past week, Delta Electronics gained 16.8%, and Winbond added 18.6%. These are not AI pure-plays but beneficiaries of overall supply chain confidence. The moves suggest investors are rotating back into Taiwan defensives that sold off in January on tariff fears.
What's underappreciated: Taiwan's semiconductor exports to the US hit record highs in 4Q25 despite tariff uncertainty, meaning much of the demand is structural (AI buildout) rather than discretionary. If tariffs stabilize at low-to-mid teens rather than the 25%+ feared in January, the earnings impact is manageable and likely already reflected in consensus estimates. The tailwind is removal of worst-case scenarios, not new bullish catalysts. (24 Feb 2026)

Canada's AI safety minister summoned OpenAI executives to Ottawa after the company confirmed it flagged but did not report a teenage user's suspicious ChatGPT activity weeks before a mass shooting in Tumbler Ridge, British Columbia. The case marks the first government enforcement action targeting AI companies for failure to escalate safety warnings, and could set precedent for mandatory reporting requirements globally.
OpenAI's internal safety systems detected concerning usage patterns from the suspect's account before the shooting but did not notify law enforcement. Canadian officials are now questioning whether existing AI safety protocols are sufficient or whether regulatory mandates are needed. The outcome will shape how AI companies balance user privacy against public safety obligations, particularly for conversational AI systems that lack the content filtering layers of social media platforms.
For investors, this introduces a new regulatory risk category: mandatory reporting obligations could require significant compliance infrastructure investments and expose AI companies to liability for user actions. The debate parallels social media content moderation battles but with higher stakes given AI's interactive nature. OpenAI, Anthropic, and Google (via Gemini) all face similar exposure. The timing is notable: this follows Anthropic's disclosure of Chinese distillation attacks, suggesting AI safety and national security issues are converging into a broader regulatory push.

OpenAI formalized consulting partnerships with McKinsey, BCG, Accenture, and Capgemini to accelerate enterprise AI agent deployments, effectively outsourcing go-to-market to avoid building a direct enterprise sales force. The "Frontier Alliances" structure has the consultancies reselling OpenAI's tools while providing integration services, capturing margin that OpenAI would otherwise keep in a traditional SaaS model.
This is a defensive move disguised as expansion. OpenAI's consumer ChatGPT business has hit growth plateaus (user engagement metrics leaked in January showed flattening), and the company needs enterprise revenue to justify its US$100bn+ valuation. But enterprise sales require relationship management, multi-year contracts, and customization, none of which fit OpenAI's product DNA. Outsourcing to consultancies solves distribution but compresses margins: the consultancies will capture 30-50% of contract value, versus the 70%+ gross margins typical of direct SaaS sales.
The competitive dynamic is also shifting: at least a dozen venture funds now back both OpenAI and Anthropic, abandoning traditional exclusivity norms. This dual-investment positioning suggests VCs see the AI model layer commoditizing faster than expected, with differentiation moving to application layers and integration services. For OpenAI, the consulting partnerships are a hedge against margin compression, but the strategy acknowledges that frontier model APIs alone won't generate the returns needed to cover US$5bn+ annual compute costs.
The investor read-through: OpenAI's valuation increasingly depends on enterprise adoption velocity, not just model capabilities. If enterprise sales cycles prove slower than projected (typical for new infrastructure categories), the company will struggle to grow into its valuation before the next fundraise. Microsoft and Oracle, as infrastructure partners, are the clearest beneficiaries. (23 Feb 2026)
