The AI trade remained the biggest market story in mid-May, but investors started showing the first signs of caution as they moved closer to the next major test: Nvidia earnings.
Technology stocks had already posted massive gains in 2026, driven by chips, AI infrastructure, and data-center spending. But by May 17, some traders began locking in profits as expectations continued rising.
The concern was simple: AI demand still looks strong. The question became whether earnings could stay strong enough to justify valuations.
Semiconductor names remained at the center of attention, with investors focusing on:
- AI chip demand
- Hyperscaler spending
- Blackwell production ramp
- Data-center expansion
Markets were especially watching NVIDIA because many investors viewed its report as a broader test for the entire AI ecosystem.
Expectations were already extremely high. Consensus estimates pointed to roughly $79 billion in quarterly revenue, while analysts expected continued growth in data-centre sales, the segment driving most of Nvidia’s AI expansion.
The rally was not limited to Nvidia.
AI-linked stocks across memory, networking, servers, and infrastructure had also surged, leading to growing debate about whether the market was entering another phase similar to earlier technology booms. At the same time, strong earnings momentum kept many investors bullish.
For markets, May 17 became less about what AI had already done. It became about what comes next.
If Nvidia delivered another strong quarter, the AI rally could continue. If not, profit-taking risk was already waiting.
