Alphabet beats forecast, but AI spending surge faces investor scrutiny

Alphabet's earnings beat demonstrates that the company can still deliver strong financial results despite a substantial increase in capital spending. However, the timing of these results is significant: they represent the first major test of investor tolerance for the elevated AI spending that has characterized the tech industry. The core tension is whether the large sums being deployed for AI infrastructure will eventually translate into measurable business returns, a question that remains unresolved.

Tesla's situation illustrates the inverse problem. Rather than facing scrutiny for spending too much, the EV maker is being penalized by markets for potentially spending too little on AI relative to its own stated ambitions. The gap between Musk's $25 billion（約4兆円） 2026 capex forecast and Tesla's current trajectory signals to investors that the company may lack the conviction or resources to fully commit to its AI strategy, resulting in an immediate market reaction and share price decline.
