The Nasdaq is slipping as investors show caution about how much companies will spend on artificial intelligence and what that will mean for future earnings. The decline comes as market participants look toward upcoming results from large technology firms, including Microsoft, Amazon, Meta and Apple next week. Sentiment has softened after Alphabet announced a substantial increase in AI-related spending, prompting concerns that similar spending could pressure near-term margins across the sector. Investors are therefore watching not only revenue and profit figures, but also guidance and indications of whether AI investments translate into measurable growth. Across sources, the focus is on expectations before earnings releases and the broader question of how companies balance rapid AI deployment with cost control. The market reaction reflects uncertainty as traders adjust positions ahead of multiple high-profile reports.
