Nvidia enters a pivotal week for the AI trade, with investors weighing whether the world's most valuable company can push its market capitalization past the $6 trillion threshold. The stock closed Friday at $229.28, valuing the company at $5.54 trillion, after approaching $5.78 trillion earlier in the week. A move toward $249 would bring it near the $6 trillion mark.

Three key events this week could shape Nvidia's next move: US inflation data on Wednesday, ASML's earnings, and TSMC's results on Thursday. Each offers a different lens on the sustainability of AI-driven demand and the cost of capital that underpins it.

CPI: The Cost of Growth

September CPI arrives Wednesday at 8:30 a.m. ET, with economists expecting headline inflation around 3.7%. The 10-year Treasury yield ended Friday near 5.24%, close to a 24-year high. Higher yields reduce the present value of future profits and raise financing costs for the data-center build-out that supports demand for Nvidia's chips.

Deutsche Bank strategist George Saravelos noted that investors increasingly see something going wrong in the AI ecosystem as their biggest systemic concern, with AI concentration risk still "under-priced by the market." A hotter CPI print could hit Nvidia from two directions: compressing its valuation multiple while raising the cost of funding AI infrastructure.

ASML: A Gauge of Chipmaking Investment

ASML reports before European markets open on Wednesday. The Dutch equipment maker's lithography machines are essential for manufacturing advanced semiconductors, making its results a barometer for chipmakers' willingness to invest in future capacity. The company guided for third-quarter sales of €11 billion to €12 billion and has projected 2026 EUV system revenue growth of more than 45%, driven by advanced logic and DRAM demand.

The key metric may be bookings. Strong orders would signal that foundries and memory producers still see AI demand justifying expensive capacity additions years out, supporting Nvidia's longer-term growth assumptions. UBS analyst Timothy Arcuri reiterated a Buy rating and $300 price target on Nvidia last week, citing Taiwan's September computing-equipment exports as "consistent with healthy underlying AI-driven demand."

TSMC: The Closest Thing to an Earnings Preview

TSMC reports Thursday and is expected to deliver a sixth consecutive quarter of record profit. Analysts surveyed by LSEG expect net income to jump about 65% to T$746.3 billion, after third-quarter revenue rose 50% to a record T$1.49 trillion. For Nvidia investors, TSMC matters more than almost any other external report, as it manufactures Nvidia's leading processors and sits inside the advanced-packaging supply chain that has constrained AI-chip output.

Forward-looking questions will dominate: fourth-quarter guidance, 2027 AI demand, advanced-node utilization, and CoWoS capacity. Stifel analyst Sahej Singh noted that TSMC's third-quarter revenue finished about 2% above the top of guidance and roughly 2.5% ahead of consensus. He expects Thursday's call to produce guidance strong enough to lift TSMC's full-year growth outlook, which would strengthen the case that Nvidia's demand runway remains intact.

Together, these three data points will test whether the AI trade can sustain its momentum. A benign CPI print, solid ASML bookings, and upbeat TSMC guidance could reinforce confidence in Nvidia's growth trajectory. Conversely, any disappointment could amplify concerns about valuation and the durability of AI spending.
