The Technology Sector Review will be published on the first Tuesday of each month, giving a clear snapshot of how the U.S. technology sector is performing, what is driving the trends, and what business and investment audiences should watch. This inaugural edition covers the broader picture for 2026 while focusing on the developments of the last month and on how the U.S. tech landscape has shifted since the war in Iran began in February. Yesterday’s U.S.-Iran two-week ceasefire, including a pledge to reopen the Strait of Hormuz, has sparked initial market relief, with oil prices dipping and equities rising modestly.
U.S. technology stocks have stayed near the front of the equity market in early 2026, helped by strong earnings and rising AI-related infrastructure spending, even as the tone has shifted from pure AI hype to a more measured focus on returns. The NASDAQ-100 index ended the first week of April near 24,200 points, reflecting a roughly 30% gain since the start of 2025’s final quarter. That outpaces the U.S. broad market, underscoring that tech remains the growth engine of the U.S. equity universe despite the wartime backdrop, and now with early signs of de-escalation.
AI Infrastructure Surge
At the heart of the story is the decision by several large U.S. tech firms to ramp up capital spending on AI-related infrastructure. Amazon (NASDAQ: AMZN), Alphabet (NASDAQ: GOOGL), Meta (NASDAQ: META), and Microsoft (NASDAQ: MSFT) are together planning to spend roughly $650 billion on capital expenditures in 2026, with the bulk of that money aimed at data-center capacity, AI hardware, and supporting infrastructure. Market-intelligence and news outlets that track these companies estimate that this spending is about 60% higher than the previous year and roughly on par with the annual economic output of a mid-sized country like Chile.
This capex wave translates to real momentum. Microsoft’s Azure cloud posted Q1 beats from enterprise AI adoptions, while Amazon Web Services expanded sovereign cloud offerings. NVIDIA (NASDAQ: NVDA) leads hardware demand with its GPUs. Alphabet’s Google Cloud gained traction in regulated AI workloads, and Meta optimized open-source models for efficiency. Investors now prioritize capex efficiency, those converting builds to revenue and margins will outperform, ceasefire or not.
Iran War Disruptions
Those numbers are now being read through the lens of the war in Iran. Analysts at International Data Corporation (IDC) note that the conflict has added pressure on global IT spending, tempering earlier forecasts from 11% to 9% growth and forcing companies to reassess timelines for some projects, especially those tied to consumer demand and discretionary enterprise spending. At the same time, the war has also highlighted the importance of resilient cloud and data-center capacity, because the digital economy is now a visible front line in the conflict.
The key takeaway is that the technology sector is now being shaped by two forces: the long-run structural shift into AI-driven infrastructure and the short-run disruptions from the Middle East conflict. The 2026 Iran war has already led Iran to identify several major U.S. technology companies as potential targets, with threats directed at their data-center and cloud-infrastructure assets in the Gulf region. Suspected Iranian drone and missile strikes have reportedly damaged data-center facilities in the region, including sites linked to Amazon Web Services, which has raised concerns about regional resilience and insurance costs for digital infrastructure. The ceasefire offers tentative relief here, potentially stabilizing insurance and project delays.
Supply Chain Vulnerabilities
Beyond direct physical attacks, the war has also complicated semiconductor supply chains. The Middle East is a key supplier of critical materials such as helium (30% of global supply for chip lithography), aluminum, and bromine, all of which are used in chip manufacturing, and disruptions to shipping and regional production would extend the vulnerability window for chipmakers by several months, according to commodity and supply-chain analysts. Morningstar and macro-research firms warn that any prolonged disruption to the Strait of Hormuz or to regional energy facilities could tighten supplies of AI-related memory chips and increase costs for hyperscalers building out data-center capacity.
That has already contributed to volatility in the share prices of key chipmakers such as Samsung Electronics (KRX: 005930.KS) and SK Hynix (KRX: 000660.KS), as investors weigh AI-driven demand against the risk of supply-chain breakdowns, DRAM prices jumped 20% in March alone. The ceasefire and Hormuz reopening pledge could ease this pressure, shortening supply gaps and capping chip inflation at 5-7% for the year. U.S. policy like the CHIPS Act accelerates domestic fabs, further mitigating risks long-term.
Policy and Resilience Focus
The evidence is that AI-related capex is still a powerful tailwind, but it is now running up against a new set of geopolitical headwinds. The White House’s National Policy Framework for Artificial Intelligence, released in March, calls for a more coordinated federal approach to AI rules and stresses that governments must ensure secure and resilient AI infrastructure, partly in response to the hybrid cyber and kinetic warfare unfolding in the Middle East. At the same time, U.S. and European firms are investing more in cybersecurity and cloud-resilience measures, with data-centres and networking platforms becoming critical infrastructure in both economic and national-security planning.
Outlook Amid Uncertainty
Seen together, the 2026 picture is of a sector that is growing, expensive, and policy-sensitive. The U.S. tech rally is anchored in real capex and real earnings, but the war in Iran has added pressure on supply chains, raised the risk of targeted physical and cyber attacks, and added a layer of uncertainty around how quickly global IT spending can rebound. The ceasefire provides breathing room, with markets rallying on lower oil and supply hopes, but watch Hormuz flows and truce adherence.
