HSBC says worries about excessive spending on artificial intelligence infrastructure have become the leading issue shaping sentiment around AI-linked stocks. The bank’s view points to a change in focus for investors, who are paying closer attention to how much major technology companies are committing to AI buildouts.

According to the report, concerns about aggressive AI investment are now weighing on the outlook for AI-related equities. Instead of looking only at the long-term promise of artificial intelligence, the market is also examining whether current spending levels are justified.

That matters because large technology groups have been racing to expand the computing power and infrastructure needed for AI. As those costs rise, investor attention appears to be shifting toward the scale, pace and potential payoff of that spending.

HSBC’s assessment suggests that AI market sentiment is being driven less by broad enthusiasm alone and more by questions over capital discipline. For AI-focused shares, the debate over overspending on infrastructure has become a central theme in how the sector is being viewed.
