Chip earnings season heats up; NVDA, AMD, AVGO face investor scrutiny amid AI capex saturation fears

Semiconductor companies face a critical earnings gauntlet in the coming week, with NVIDIA's results on May 21 anchoring a cascade of announcements from AMD, Broadcom, Qualcomm, and others. The cohort enters earnings season with some of the highest valuations in the sector's history, driven by an outsized rally on AI infrastructure demand. But market participants are increasingly asking a hard question: has peak capex arrived, or is there still meaningful runway left in the cycle?

The Friday selloff in chip stocks (AMD -3.3%, NVDA -2.2%, MU -5%) demonstrated both the bullish positioning and the fragility of sentiment. Yields rising and oil prices surging signalled that macro headwinds were real, and in a higher-rate environment, the free cash flows that justify semiconductor valuations face pressure. Additionally, some equity researchers began floating hypotheses that the flurry of AI accelerator shipments from NVDA, AMD, and others in 2024-2026 might be approaching a plateau, with demand growth slowing in 2027-2028 unless new workloads emerge.

NVIDIA is the bellwether. With the company trading near all-time highs and having added roughly $1 trillion of market cap in a matter of days (now at $5.7T valuation), the bar for earnings is exceptionally high.

Broadcom and others offer a secondary lens: if the broader AI infrastructure buildout is still accelerating, telecom and data centre equipment providers should show broad strength. If, conversely, the leaders are seeing softness, the narrative shifts to AI capex being geographically or customer-concentrated, raising questions about the durability of the rally. The consensus euphoria around semiconductors has been tested by macro volatility, and earnings will determine whether the market re-rates the sector higher or validates caution. A pivotal week awaits.
