Google and Tesla shares plunge as AI spending rattles markets

July 23, 2026 - 18:43

Shares of Google and Tesla took a sharp hit on Tuesday, as investor anxiety over massive artificial intelligence spending spread through the tech sector. The selloff came after both companies reported quarterly earnings that showed heavy investment in AI infrastructure without clear signs of immediate profit.

Google parent company Alphabet saw its stock fall more than 7% after revealing it plans to spend $75 billion on AI-related projects this year alone. That figure far exceeded analyst expectations and raised concerns that the company is pouring money into a technology that has yet to deliver a strong return. Tesla also dropped over 5% after its earnings report highlighted rising costs tied to AI development for self-driving systems and robotics.

The broader market felt the pressure. The Nasdaq composite index slid more than 2%, dragged down by other big tech names like Microsoft and Amazon, which have also committed billions to AI. Investors are growing impatient with the narrative that AI will eventually transform industries. They want to see actual revenue growth and cost savings now.

Some analysts argue that the current spending spree is necessary to stay competitive. But the market's reaction suggests a growing skepticism. If the next round of earnings does not show tangible results, the selloff could deepen. For now, the message is clear: investors are done betting on promises. They want proof.
