NEW YORK/LONDON, July 17 (Reuters) - Share indexes tumbled around the world on Friday, as heavyweight chip stocks plunged for a third consecutive day as investors reduced bets on artificial intelligence, with China's Moonshot releasing a large AI system.
Meanwhile oil prices rose as the United States and Iran expanded their attacks to hit key infrastructure. The United States struck bridges and an airport in Iran, and Tehran responded by hitting a power and desalination plant in Kuwait.
In the contested Strait of Hormuz, where the renewed conflict has again cut off global energy supplies, U.S. Marines boarded a tanker, and another ship was reported to have been hit by a projectile.
In its third straight day of losses, the Philadelphia semiconductor index dipped to a level 23.5% below its most recent record closing high, reached on June 22. It was last down more than 2% on the day.
While investors were shying away due to worries about rich tech valuations and the sustainability of AI capital spending growth, Mona Mahajan, head of investment strategy and asset allocation at Edward Jones, noted that energy stocks were rallying with oil prices.
Defensive assets such as government bonds were also in demand, along with safer equity sectors such as utilities.
"We're seeing a bit of a defensive trade take hold this morning ... and at bottom of the list of sector performance is the AI technology part of the market," said Mahajan.
She said the sector had already risen "in a parabolic fashion, and we know those types of trades tend to not last indefinitely".
She also pointed to the unveiling by Chinese AI startup Moonshot of Kimi K3, which it said was the world's largest open-weight AI system, delivering performance close to U.S. giant Anthropic's frontier model.
On Wall Street at 11:02 a.m. (1502 GMT) the Dow Jones Industrial Average was down 100.93 points, or 0.19%, at 52,452.04, the S&P 500 was down 64.07 points, or 0.85%, at 7,469.70 and the Nasdaq Composite was down 418.14 points, or 1.62%, at 25,463.81.
MSCI's gauge of stocks around the globe fell 12.52 points, or 1.12%, to 1,109.17.
The pan-European STOXX 600 index fell 0.61%.
Losses were more severe in Asia, with MSCI's broadest index of Asia-Pacific shares excluding Japan finishing down 2.7%, while Japan's Nikkei tumbled 4%, putting it 12% below its recent peak.
Taiwan's stock market plunged more than 6% for its worst day since a selloff in April 2025 related to U.S. President Donald Trump's import tariffs.
Four leading AI models discuss this article
"The 23.5% drawdown in the Philadelphia Semiconductor Index already reflects much of the AI-valuation reset, so further downside is likely limited absent worse geopolitical shocks."
The article paints a classic risk-off day: semis down 23.5% from June 22 peak on AI-capex doubts, exacerbated by China's Moonshot Kimi K3 release, while oil spikes on genuine Hormuz supply disruption. Nasdaq -1.62%, Nikkei -4%, Taiwan -6%. Defensive rotation into utilities, bonds, and energy is evident. Yet the piece buries that this is the third straight down day after parabolic gains; forward P/E compression from ~35x to ~25x on semis may already price in much of the AI-skepticism. Missing: actual volume on the sell-off, any read-through to July earnings, and whether U.S./Iran escalation is already partially priced after weeks of saber-rattling.
If the Strait of Hormuz remains closed for weeks, oil could spike to $110+, forcing central banks to keep rates higher for longer and torpedoing the soft-landing narrative that has underpinned the entire 2025 equity rally.
"The combination of energy-driven inflation and the collapse of the AI valuation premium creates a high-risk environment where traditional defensive sectors will fail to protect portfolios from systemic volatility."
The market is currently pricing a 'double-whammy' of geopolitical supply-side shocks and a cyclical AI valuation reset. While the 23.5% drop in the SOX index suggests a technical bear market, the real danger is the Strait of Hormuz disruption. If energy prices spike, the 'higher-for-longer' interest rate narrative returns, crushing the valuation multiples of high-growth tech. The rotation into utilities and government bonds is a classic flight to safety, but it ignores the inflationary tail risk of a sustained regional conflict. We are moving from a 'soft landing' consensus to a 'stagflationary' reality check where AI efficiency gains cannot offset the cost of energy-driven supply chain fragmentation.
The sell-off in semiconductors may be a temporary liquidity event triggered by margin calls rather than a fundamental shift in AI demand, potentially setting up a massive 'buy-the-dip' opportunity once the geopolitical noise subsides.
"The semiconductor selloff is real and justified on valuation grounds, but the article's framing of Moonshot's K3 as a demand-killer is premature—what matters is whether this accelerates or merely redistributes AI capex spending."
The article conflates three distinct shocks—AI valuation repricing, geopolitical escalation, and Chinese competitive threat—but treats them as a unified bearish narrative. The semiconductor selloff (SOX down 2%+, Taiwan -6%) is real, but the article doesn't distinguish between cyclical profit-taking after a 40%+ run and structural demand destruction. Oil's rise on Middle East conflict is genuine, but Strait of Hormuz disruptions have historically been brief and priced quickly. The Moonshot K3 announcement is overstated—'close to Anthropic's frontier model' is marketing language, not proof of parity. Most critically: if AI capex is unsustainable, why are energy stocks rallying? That's a hedging trade, not a reversal signal. The real risk is duration: how long does geopolitical tension persist?
If U.S.-Iran escalation persists beyond weeks, oil could spike 20-30% and trigger stagflation fears that crush both growth stocks AND energy rallies. Alternatively, if Moonshot's K3 actually closes the AI capability gap, it could justify a structural repricing of semiconductor and AI infrastructure valuations downward—not a temporary dip.
"Near-term semiconductors face a risk-off pullback, but long-run AI demand and supply tightness imply a rebound in SMH once risk appetite returns."
Taken at face value, the global stock slide looks like AI hype unwinding and geopolitics driving oil higher. The Moonshot K3 chatter and a 23.5% drop from June highs hint at a risk‑off reset, but the negative thesis rests on fragile, near‑term momentum rather than a lasting demand collapse. The article glosses over potential resilience in pockets of chip demand—memory, edge AI accelerators—and the possibility that AI capex remains intact if data‑center growth proves sticky. A softer macro backdrop could also still be a buying opportunity if rates stabilize and sentiment improves. Watch SMH components for dispersion; a rebound could be swift if risk assets stabilize.
Counterpoint: if AI spending remains durable and Moonshot's system proves credible, the semis rally could resume quickly; the sell-off may simply reflect a first-stage rotation rather than a durable top.
"Hormuz duration risk directly undermines the soft-landing premium still embedded in semis valuations."
Claude correctly flags the conflation of shocks but underweights the second-order effect: sustained Hormuz closure doesn't just spike oil 20-30%; it forces Fed pause on cuts, directly invalidating the soft-landing equity premium that has kept semis at 25x forward despite slowing capex signals. Energy rally is a hedge, yet duration risk could flip it into stagflation catalyst nobody has fully priced.
"The Moonshot K3 release represents a structural threat to US chip dominance that could permanently impair semiconductor valuation multiples."
Claude, your dismissal of the Moonshot K3 threat is dangerous. If China achieves near-parity in frontier models, the 'moat' for US semiconductor giants evaporates, turning a cyclical valuation reset into a structural secular decline. We aren't just looking at a capex pause; we are looking at the potential end of the US AI hardware monopoly. If the geopolitical energy shock forces a Fed pivot while our AI competitive advantage erodes, the downside risk to the SOX is significantly deeper than 25x forward P/E implies.
"Moonshot's threat is real but operates on a different timescale than today's geopolitical shock—conflating them obscures what's actually driving current volatility."
Gemini conflates two separate risks into one doomsday scenario. Yes, Moonshot K3 threatens US semiconductor moats—but that's a 12-18 month structural story, not a catalyst for today's selloff. The immediate shock is geopolitical oil, not Chinese AI parity. Conflating timescales obscures what's actually priced now versus what's speculative. If Hormuz closes for weeks, oil spikes regardless of Moonshot's capabilities. Don't let structural fears hijack tactical analysis.
"Moat erosion from Moonshot K3 isn’t imminent; near-term risk is rate/capex timing and oil persistence, not a guaranteed multi-year structural decline."
Gemini’s case rests on near-term Moonshot parity destroying US chip moats. I’d push back: moat erosion is a multi-year risk, not a few quarters. Near-term drivers are rate paths and capex timing, plus data-center funding costs. If Hormuz stays volatile, oil-driven persistence could overwhelm any AI-competitiveness narrative, keeping SOX under pressure even if frontier models improve.
The panel agrees that the market is experiencing a risk-off day due to AI capex doubts, geopolitical tensions, and oil supply disruptions. They disagree on the severity and duration of these impacts, with some seeing a cyclical reset and others warning of structural changes and stagflation.
