Chip and AI stocks plunge after Trump announces plans to strike Iran
Chip stocks and companies linked to artificial intelligence went into freefall last Thursday, and the reason was a primetime address by Donald Trump on Wednesday night.
The U.S. president stated that the country would hit Iran extremely hard over the next two to three weeks. That declaration was enough to shake global financial markets in a pretty significant way, triggering a wave of risk aversion that spread rapidly across every sector of the economy — but hit technology and semiconductor companies with extra force.
The impact was immediate: the Nasdaq Composite plunged about 2%, the S&P 500 dropped roughly 1.3%, and the Dow Jones fell close to 1.4%. Meanwhile, oil prices went in the opposite direction and surged, with Brent climbing around 7.6% and Crude Oil jumping an impressive 12.2%. This inverse movement between energy commodities and tech assets is no coincidence — it reveals something very important about how markets perceive geopolitical risk these days.
Beyond the military threat, Trump also blamed Iran for the recent rise in gasoline prices in the United States, claiming that attacks on oil tankers and regional targets were responsible for the increase. At the same time, he signaled the conflict could be short-lived and that talks with Tehran were still ongoing. American lawmakers, for their part, reacted in a fairly divided fashion to the address, highlighting the internal polarization around the issue.
But what does a geopolitical threat actually have to do with the tech market? A lot more than it might seem. The chip sector functions as a real barometer for global tension, and when the political world heats up, the stock markets feel it — especially the companies that power the infrastructure behind artificial intelligence.
Why chips and AI get hit so hard by geopolitical tensions
The semiconductor supply chain is one of the most globalized and fragile in existence. Rare metals mined in specific regions of the world, factories concentrated in a handful of Asian countries, maritime shipping routes that cross potential conflict zones — all of this means that any international political instability reverberates directly in the cost and availability of components. When Donald Trump signals a military action against Iran, investors are not just thinking about oil. They are calculating the impact across an entire logistics chain that supports the production of chips used in servers, data centers, and devices running artificial intelligence applications.

On top of that, there is a powerful psychological factor at play. The tech market, especially chip stocks, had been on a pretty positive trajectory in recent months, fueled by the generative AI boom and growing demand for GPUs and specialized processors. That accelerated growth, however, leaves companies in the sector more exposed to sharp corrections when uncertainty triggers appear. It is like a car traveling at high speed — any obstacle in the road causes a much bigger impact than it would at cruising speed. Trump’s statement worked exactly like that unexpected obstacle on a highway where traffic had been flowing smoothly.
Another relevant point is that companies like Nvidia, AMD, TSMC, and Broadcom have direct or indirect exposure to the Middle Eastern market and the trade routes that pass through the Persian Gulf region. Any sign of conflict in that area raises questions about energy supply disruptions to data centers, potential economic sanctions affecting trade partners, and of course the rise in oil prices, which makes everything more expensive — from shipping components to the operational costs of semiconductor factories around the world.
Oil goes up, tech goes down: understanding the connection
The sharp rise in Brent and Crude Oil was not just a speculative reaction to Trump’s speech. It reflects a well-established economic logic: when there is a threat of conflict in the Middle East, oil supply can be compromised, and traders already price that risk in ahead of time. Iran is one of the largest oil producers in the world and has direct influence over the Strait of Hormuz, through which a massive share of globally consumed oil passes. Any military action in the region has the potential to disrupt that flow and create an immediate supply shock in energy markets.
Now, when oil spikes abruptly, the cascading effects reach technology and artificial intelligence companies fast. Data centers, which are the backbone of the entire AI infrastructure, consume an enormous amount of electricity. With fuel prices climbing, energy generation costs rise, and that additional cost either gets passed along or absorbed by companies in the sector, eroding margins and reducing the attractiveness of their stocks. Major players like Microsoft, Google, and Amazon, which invest billions in cloud and AI infrastructure, are directly exposed to this dynamic when energy prices surge unexpectedly.
There is more: rising oil prices also fuel expectations of higher inflation, which leads investors to reassess their bets on growth assets — exactly the category where chip stocks and AI companies fall. In a scenario of rising inflation, interest rates tend to climb or stay elevated for longer, which reduces the present value of future earnings for these companies. The market does not wait for confirmation; it anticipates. And that is exactly what happened during Thursday’s session, with massive sell-offs in tech stocks right after the American president’s remarks.
Which companies felt the impact the most?
Chip stocks led the losses during this turbulent session. Nvidia, the ultimate symbol of the AI boom, dropped around 2%. AMD fell close to 3%, joined by Broadcom, which also lost nearly 3%. Qualcomm saw a decline of approximately 2%.
In the memory and chip design segment, the impact was even more severe. Micron Technology plunged about 5%, while Arm Holdings and Marvell Technology each dropped roughly 4%. Taiwan Semiconductor Manufacturing (TSMC) and Lattice Semiconductor fell close to 3%, while Analog Devices and Texas Instruments slid about 2%. GlobalFoundries posted a more modest decline, around 1%.
In the networking and AI infrastructure space, the picture was also one of widespread losses. Celestica dropped around 4%, while Arista Networks, Lumentum, Coherent, and Corning each fell about 2%. Cisco also closed in the red.
Chip equipment manufacturers followed the negative trend. ASML and Lam Research tumbled about 3%, while Applied Materials and KLA posted losses of nearly 2% each during Thursday’s session.
Exceptions that bucked the trend
Not every stock in the sector gave in to the widespread pessimism. Applied Optoelectronics surprised by climbing around 7%, while Ciena advanced about 1%. Intel, which has been going through a peculiar moment in the market, posted a gain of roughly 1%, standing out from the rest of the semiconductor sector. These contrarian moves show that even on panic-driven days, the market differentiates companies with their own dynamics and individual catalysts that go beyond the macro picture.
AI infrastructure in the eye of the storm
What makes this sell-off especially relevant for anyone following artificial intelligence is the fact that the hardest-hit companies sit at the heart of the infrastructure supporting the entire AI revolution. Nvidia, AMD, Broadcom, TSMC, Marvell — all of these companies produce the essential components that make it possible to train and run inference on large language models, computer vision systems, and the full range of applications driving the sector right now.
When these stocks fall simultaneously, it is not just about loss of market value. It is a signal that the entire AI ecosystem is exposed to factors that go well beyond the technology itself. Supply chains, energy costs, international logistics routes, and foreign policy decisions by major powers — all of this becomes part of the risk calculation for anyone investing in or working with artificial intelligence.
This interdependence between technology and geopolitics is nothing new, but it becomes increasingly evident as AI solidifies its role as a strategic asset for nations around the world. The chips that power the most advanced language models on the planet are also central pieces in trade disputes, regulatory battles, and now, very directly, in scenarios of military tension.
What to expect in the coming days
With the two-to-three-week window mentioned by Donald Trump still open, markets are likely to remain on high alert. Any new statement from the American president about Iran, or any diplomatic or military movement in the region, has the potential to trigger fresh rounds of volatility in both chip stocks and oil prices. Investors who closely follow the artificial intelligence sector need to keep a close eye on this situation, as it could create both opportunities and traps depending on how events unfold.
From a macroeconomic standpoint, the current situation reinforces a lesson the market learns and relearns cyclically: technology and geopolitics are increasingly intertwined. Artificial intelligence has moved beyond being just an innovation story to become a matter of national security, trade disputes, and diplomatic tensions.
It is worth remembering that this type of market move, while scary in the short term, does not necessarily change the long-term fundamentals of technology and AI companies. Demand for advanced semiconductors continues to grow at a rapid pace, driven by increasingly processing-intensive applications. What shifts is market sentiment and risk perception in the moment — two factors that carry enormous weight on stock prices in the very short term but can dissipate quickly depending on how geopolitical events evolve.
So what happened last Thursday was not just a market correction. It was a reminder that the AI ecosystem exists within a real world full of friction, conflicts, and interests that stretch far beyond the next model release or the next hardware upgrade. And when that real world shakes things up, the stock markets feel it — from oil to chips, all the way through the invisible infrastructure powering the artificial intelligence revolution. 🌐💻📉
