US equity futures were little changed early Monday, with contracts tied to the S&P 500 and Nasdaq 100 inching higher and building on last week's gains as enthusiasm around artificial intelligence helped counter broader macroeconomic pressure. Sentiment in AI-linked shares strengthened after Anthropic reported $11.5 billion in second-quarter revenue, supporting the view that AI model development and datacenter capital expenditure (long-term infrastructure spending) can remain robust in the medium term. The company is also meeting with banks for a potential IPO, which was described as likely to be the biggest on record. In premarket trading, memory chip makers Sandisk and Micron added to sharp gains from the previous week, while Nvidia and Amazon also edged up. More economically sensitive and traditional sectors remained weaker, extending last week's underperformance, with the Dow hovering just below flat. Walmart and Home Depot were subdued ahead of earnings later this week.
