Key Highlights

  • Apple (NASDAQ:AAPL) notched another all-time closing high on Wednesday, October 21, 2026, after trading about 1.3% higher during the session as the Nasdaq rose 1.05%.
  • Alphabet has lost about USD 860 billion in market value since its peak, nearly the size of Walmart, and slipped about 2% on Wednesday.
  • Market commentary contrasts the two: Apple has largely stayed out of the race to build AI data centres, while Alphabet is spending heavily and rationing its computing capacity.
  • The comparison is a snapshot, as Nasdaq 100 futures fell about 1.5% to 1.8% on Thursday, October 22, 2026 after mixed results from Tesla and Meta.

What Happened on Wednesday

Apple (NASDAQ:AAPL) sells iPhones, Macs and services such as the App Store, and its shares set another all-time closing high on Wednesday, October 21, 2026. Market data showed the stock about 1.3% higher during the session, while the Nasdaq Composite closed up 1.05%. Alphabet (NASDAQ:GOOGL) moved the other way, slipping about 2% after Chief Executive Sundar Pichai said Google Cloud is turning away revenue to keep computing capacity for its DeepMind research unit. Alphabet has now lost about USD 860 billion in market value since its peak, an amount close to the entire value of Walmart (NASDAQ:WMT). The gap between the two companies has become a reference point for how investors judge AI spending.

Why Lower AI Spending Has Helped Apple

AI data centres require heavy capital spending, which reduces free cash flow, the cash left after investment, until the new capacity earns a return. Apple (NASDAQ:AAPL) has not joined that build-out at the scale of its megacap peers, so its free cash flow continues to fund buybacks and dividends. Alphabet faces the opposite trade-off: Pichai's comment shows that demand for computing exceeds supply, yet capacity reserved for DeepMind means cloud revenue is deferred. Investors are therefore weighing near-term cash returns against long-term AI optionality. Meta Platforms (NASDAQ:META) raised the low end of its 2026 capital spending range to USD 135 billion to USD 145 billion, which shows how large the bill has become for those competing directly.

Risks and What to Watch

The first risk for Apple (NASDAQ:AAPL) is that staying out of the AI build-out becomes a weakness if AI features drive the next device upgrade cycle and rivals capture that value. The second is valuation: shares at record highs leave less room for disappointment in iPhone demand or services growth. The third is market-wide pressure, as Nasdaq 100 futures fell about 1.5% to 1.8% and the 10-year Treasury yield stood near 5.1% on Thursday. Higher yields weigh on richly valued shares. Investors should watch Microsoft results on Wednesday, October 28, the Fed decision the same day and Apple's fiscal fourth-quarter report, expected around the end of October.

Where Things Stand

The answer is that investors are rewarding Apple (NASDAQ:AAPL) for cash returns and a lighter AI spending burden, while Alphabet's USD 860 billion drawdown shows the cost of uncertainty over AI payback. Wednesday's record close puts that contrast at its widest. The next catalysts are the Fed decision and Microsoft results on Wednesday, October 28, 2026 and Apple's own fiscal fourth-quarter report. Market values change daily, the contrast may narrow, and this is not investment advice.
