Nikkei 225 falls hard: did Alphabet reveal AI boom’s most expensive flaw?

Japan’s Nikkei fell sharply on Friday as Alphabet’s spending plans revived doubts over how quickly the artificial-intelligence boom will translate into cash returns for the companies funding it.

The Nikkei 225 dropped 2.69% to 64,634.04 in early trading, while the broader Topix lost 1.28% to 4,002.09.

The gap reflected concentrated selling in the technology heavyweights that dominate the Nikkei.

The benchmark has now fallen more than 7% in July after entering correction territory last week, leaving investors increasingly sensitive to signals from US chip and platform companies.

Alphabet’s cash burn resets the AI trade

Alphabet shares sank about 7% in New York even after Google Cloud revenue surged 82% to $24.8 billion.

Investors instead focused on second-quarter capital expenditure of $44.9 billion and negative free cash flow of $5.9 billion, both driven by the rapid expansion of AI infrastructure.

The Google parent also raised its 2026 capital-spending forecast to between $195 billion and $205 billion from $180 billion to $190 billion.

Management said spending would remain elevated as customer demand continued to exceed available computing capacity.

The market reaction showed that growth alone is no longer enough.

Investors increasingly want evidence that higher data-centre and server spending can produce durable cash returns, rather than only faster revenue and cloud bookings.

That concern also dragged the Nasdaq more than 2% lower overnight.

Japan’s chip leaders amplify the fall

The sell-off hit the companies most closely tied to the AI hardware cycle.

Advantest dropped 6.33%, Tokyo Electron lost 5.43% and memory producer Kioxia declined 4.4%. SoftBank Group slid 7.42%, making it one of the largest drags on the Nikkei.

IwaiCosmo strategist Kazuaki Shimada said the retreat was being driven mainly by overseas technology signals rather than a deterioration in Japan’s domestic economy.

Japanese corporate earnings could help change the direction of the market if companies deliver strong guidance.

The Nikkei’s price-weighted construction also magnifies movements in high-priced technology shares, helping explain why it fell more than twice as much as the capitalisation-weighted Topix.

Domestic defensives soften the damage

The session was not a broad market capitulation.

Central Japan Railway rose 1.17% and East Japan Railway gained 0.6%, while Kawasaki Kisen and Mitsui OSK Lines also advanced. Otsuka Holdings climbed 1.6% to lead Nikkei gainers.

Those moves point to a rotation towards businesses with domestic revenues, steadier cash flows and less exposure to AI valuations.

Strong Japanese earnings could help separate local fundamentals from the global technology unwind. Another weak round of US chip results, however, would leave the Nikkei vulnerable to further selling.
