U.S. stocks are entering a pivotal week near record territory, with the market’s next move likely to hinge on whether AI infrastructure leaders can justify valuations that have already pushed the S&P 500 and Nasdaq back toward their highs.
TSMC and ASML Earnings Guide AI Chip Demand

The setup matters because the rally has become increasingly dependent on a narrow group of megacap and semiconductor names. That leaves investors focused less on the broad index level than on whether the companies supplying the AI buildout — especially Taiwan Semiconductor Manufacturing and ASML — can confirm that capital spending from Nvidia and its peers is still accelerating.

Dow Jones futures, S&P 500 futures and Nasdaq futures were set to open Sunday evening after a week in which the major indexes posted solid gains, even as small caps lagged and some AI names and biotechs underperformed. Treasury yields and crude oil were little changed, suggesting the market’s near-term direction is being driven more by earnings expectations and positioning than by a fresh macro shock.
That backdrop gives this week’s AI earnings slate outsized importance. TSMC is expected to remain one of the clearest beneficiaries of the chip boom, with market participants watching for signs that demand tied to advanced GPUs and AI servers is still strong enough to keep utilization and margins elevated. ASML, meanwhile, is the key bottleneck supplier in the semiconductor supply chain: its outlook tells investors whether chipmakers are still willing to spend heavily on the most advanced manufacturing tools needed to expand next-generation production.
For Nvidia, the implications are just as direct even before the company reports. TSMC’s foundry orders and ASML’s lithography bookings are among the best leading indicators for the durability of the AI cycle. If both firms show that demand remains robust, it strengthens the case that the current AI investment wave has more room to run. If they suggest customers are becoming more selective, it would raise questions about how much of the recent semiconductor rally is already priced in.
The market’s technical backdrop also points to a stretch where good earnings may matter more than usual. Nvidia’s shares recently held above their 50-day moving average and 200-day moving average, while ASML remains above both longer-term trend lines. TSMC has also recovered from a midyear pullback and is trading near the upper end of its recent range. That leaves all three stocks vulnerable to sharp moves if guidance disappoints, even if the broader trend remains constructive.
Adalytica’s S&P 500 trade signals show “Extreme Greed” in the index, even as awareness remains at “Extreme Fear,” a combination that typically reflects a market crowded into a bullish view but still alert to a catalyst that could reverse sentiment quickly. In practical terms, that makes AI earnings less a routine reporting cycle than a referendum on whether the latest leg higher in megacap technology can sustain itself.
A strong showing from TSMC and ASML would likely reinforce the argument that AI spending remains the dominant profit engine in global equities, supporting suppliers, designers and the biggest platforms at the center of the buildout. A weaker read would not necessarily end the AI story, but it could shift leadership away from the most expensive names and back toward a more cautious, selective market.
