Are Semiconductors Cheap? AI Demand vs. Valuations
This a16z charts-and-analysis piece examines whether the semiconductor sector is undervalued despite rapid earnings growth driven by AI capital expenditures. Semiconductors account for a large share of expected S&P earnings growth, yet forward P/E multiples sit near their 10-year average (~19.5–21x). Memory makers—exemplified by Micron—show outsized margin expansion and analyst earnings growth forecasts (~60% YoY) while some trade at low multiples (Micron ~6x as of July 21). Investors worry about the cyclical nature of semiconductors and potential future gluts. The newsletter also highlights rising consumer demand for in-person experiences (foot-traffic and movie attendance increases) and trends in entrepreneurship: Gen‑Z business applications have surged and small businesses report AI-driven productivity gains in Cleveland Fed data.
Semiconductor valuation and AI capital expenditure trends affect compute supply, hardware margins, and downstream demand drivers (e.g., digital experiences). Relevant to tech investors and companies that rely on AI infrastructure, but not an immediate platform policy or industry-shifting regulatory event.

Key Takeaways & Evidence Grounding
- Just under 50% of the S&P’s earnings growth is expected to come from semiconductors.
- A chart compiled a few weeks prior showed forward P/E for semiconductors at ~19.5x versus a 10-year industry average of 19.7x; the industry multiple had nudged closer to ~21x as of the week of publication.
- Analysts expect Micron’s earnings to grow nearly 60% year-over-year, while Micron was trading at roughly ~6x earnings as of July 21, 2026.
- Consumer spending growth on experiences has roughly tripled since 2024 and is growing about 3x faster than service spending generally; foot-traffic data (Placer.ai) shows higher Friday and Saturday night visits versus pre-pandemic levels.
- Gen‑Z new business applications more than doubled in March year-over-year; the Gen‑X:Gen‑Z ratio of new business formations moved from ~26:1 in 2020 to ~4:1 in 2026.

Micron Cheap Despite AI Rally; Low S&P 500 Valuation
Micron Technology’s shares have more than tripled year-to-date but trade at just above six times forward earnings, giving it the third-lowest valuation in the S&P 500 behind Charter Communications and General Motors. The article discusses whether the memory industry’s historic cyclicality still justifies Micron’s low multiple, noting the company’s new long-term customer agreements (including binding volume commitments, take-or-pay provisions and price floors) that Micron says generally extend through 2030 and could cover roughly half or more of revenue once completed. Nvidia’s CFO Colette Kress warned of "extreme pricing conditions in memory," which could benefit Micron as a major supplier of high-bandwidth memory for AI systems. Risks remain, including added supply (including competition from China) and contract resets, leaving debate over whether Micron deserves a valuation re-rating.

Chip Stocks Surge as AI Buildout Concerns Ease
Chip stocks rallied strongly in April after a weak March driven by investor anxiety over AI infrastructure spending. Nasdaq’s PHLX Semiconductor Sector Index fell 6.3% in March but climbed roughly 35.2% from the start of April through the referenced market close as investors returned to the sector. Several major firms — including Intel, Nvidia and Apple — posted positive earnings or guidance that supported the rally. Analysts called the month’s semiconductor gains "historic," while others warned of real supply‑side constraints tied to geopolitics, such as helium export disruptions and data‑center equipment shortages related to the Iran war. The piece also notes broader AI ecosystem developments, including funding talks at Anthropic and record profits at Samsung driven by chip demand.
