Nasdaq futures pointed lower ahead of Tuesday's open, reflecting a more cautious tone in global markets as investors reassessed the outlook for AI chip stocks. The weakness suggested pressure on technology shares before a closely watched round of corporate earnings.

Market sentiment appeared to soften around companies tied to the artificial intelligence boom, an area that has helped drive major gains in recent months. With earnings approaching, traders seemed less willing to keep pushing valuations higher without fresh reassurance from company results.

The move in Nasdaq futures also matched a broader wait-and-see mood across world markets. Investors were watching whether upcoming reports would support expectations for continued growth in AI-related demand and justify the strong performance of chip-linked stocks.

For now, the lower futures signal showed that enthusiasm around AI remained intact but more fragile heading into a pivotal earnings period. Any updates on demand trends, spending plans or broader tech outlooks are likely to shape the market's next move.
