AI Valuation Concerns Trigger Sell-Off Across Asia

Asian markets suffered a steep sell-off on Wednesday, mirroring the declines on Wall Street amid mounting concerns that artificial intelligence stock valuations have outpaced underlying fundamentals. The correction, sparked by a shift in sentiment following warnings from major U.S. financial institutions, is being viewed as the first serious test of the AI-led market rally that has dominated 2025.

Japan’s Nikkei 225 plunged 3.48%, falling below the key 50,000 mark for the first time in weeks, with the broader Topix down 2.27%. The biggest drag came from SoftBank Group, which lost nearly 12%, a reflection of its heavy exposure to high-growth, high-valuation tech assets. The impact was even more pronounced in South Korea, where the Kospi index dropped nearly 6%, led by semiconductor giants Samsung Electronics and SK Hynix, down more than 7% and 8% respectively. The tech-heavy Kosdaq declined 5.39%, underscoring the severity of the sentiment shift.

In China, the Hang Seng Index fell 1.36% and the CSI 300 lost 0.9%. The broader Asia-Pacific region also felt the pressure, with Australia’s ASX 200 sliding 0.77%, a relatively modest decline but still reflective of investor defensiveness.

Wall Street Correction Sends Shockwaves Globally

The overnight decline in U.S. equities set the stage for Asia’s retreat. The S&P 500 dropped 1.17% to 6,771.55, the Nasdaq Composite fell 2.04%, and the Dow Jones lost 0.53%. These moves followed sharp losses in AI-linked firms, notably Palantir, which plunged 8% despite beating earnings expectations and raising its guidance. The market reaction reveals a critical disconnect: investors appear increasingly unwilling to support even strong results if they believe valuations are unsustainable.

The correction is not isolated, it stems from a broader market context. The S&P 500’s forward price-to-earnings ratio has climbed above 23, nearing dot-com era extremes. This valuation level, according to FactSet data, is historically associated with overbought conditions. As Anthony Saglimbene of Ameriprise noted, “without a pullback, valuations are beginning to get really stretched.”

Strategists Warned; Markets Finally React

The sharp sell-off followed recent warnings from Goldman Sachs CEO David Solomon and Morgan Stanley CEO Ted Pick, who both predicted a 10–20% correction over the next one to two years. Speaking at the Global Financial Leaders’ Summit in Hong Kong, the CEOs advised investors to remain invested but prepare for drawdowns as part of normal market cycles. Their remarks catalyzed a reversal in risk appetite, triggering the long-anticipated cooling of what has been dubbed the "everything rally."

Andrew Jackson, head of Japanese equity strategy at Ortus Advisors, framed the moment clearly: “Finally, a sell-off hits the tape,” attributing the timing to accumulated investor anxiety and the high-profile warnings from market leaders.

Causal Links and Structural Shifts in Sentiment

The relationship between AI exuberance and this market pullback is both causal and structural. AI stocks, by driving index valuations higher, created a situation where broader equity markets became vulnerable to any recalibration of expectations. With AI-led earnings growth increasingly priced in, the room for disappointment or even neutrality has shrunk. Even strong guidance from AI darlings like Palantir failed to prevent price collapses, suggesting that the market’s tolerance for lofty multiples is waning.

Asia’s reaction is not merely correlative. Given the region’s heavy concentration in semiconductors and tech platforms feeding the AI ecosystem, its exposure is direct.

A Healthy Correction or Broader Repricing Ahead?

While some analysts view this sell-off as a healthy pause, the depth and breadth of the correction indicate it may be the start of a more prolonged valuation adjustment. With interest rates remaining high and monetary policy paths uncertain, the market may struggle to justify previously inflated AI-driven multiples.

In the near term, volatility is likely to persist as investors reassess risk across sectors. As earnings season continues, the pressure will intensify on AI firms to deliver not just growth but profitability aligned with realistic expectations. Asia, given its tech dependence, will remain highly sensitive to these shifts making the next few weeks critical for global equity sentiment.
