Stock Market Today: Nasdaq Falls 1.4% as Alphabet Earnings Shock Rattles AI Trade; Dow Slips 0.3%

New York, Oct. 30, 2026 — U.S. stocks closed lower on Thursday, with the Nasdaq Composite leading declines as a historic earnings miss from Alphabet reignited fears that massive AI spending is crushing profitability, overshadowing a strong reading on economic growth.

The Nasdaq Composite fell 1.36% to close at 26,188.08, while the S&P 500 slipped 0.31% to 7,721.02 . The Dow Jones Industrial Average dropped 0.25% to 52,345.80, though 23 of its 30 components actually finished higher, reflecting the selloff’s concentration in megacap tech .

Why Did the Stock Market Fall Today?

1. Alphabet’s earnings disaster dominated the narrative. Google’s parent company reported third-quarter adjusted earnings of $2.12 per share**, missing the consensus estimate by nearly **28%** and declining 26% year-over-year . Revenue excluding traffic acquisition costs came in at **$111.21 billion, also below expectations .

More alarming to investors: Alphabet reported negative free cash flow of $9.1 billion**, far wider than the **$3.5 billion deficit analysts had anticipated, as capital expenditures surged to fund AI infrastructure . The company’s search business also showed weakness, with revenue of $63.4 billion** falling short of the **$64.9 billion consensus, raising concerns that AI chatbots like ChatGPT and Claude are eroding Google’s core franchise .

Alphabet shares plummeted 12.6%, their worst single-day performance in history .

2. ServiceNow and Fortinet added to the tech gloom. Enterprise AI platform ServiceNow plunged 27% after missing earnings estimates and guiding remaining performance obligations growth below consensus . Cybersecurity firm Fortinet tumbled 20.1% despite beating estimates, after cutting its full-year service revenue forecast .

3. Elevated inflation data weighed on sentiment. A key inflation gauge released Thursday came in hotter than expected, adding to concerns that the Federal Reserve may need to maintain restrictive policy even as tech earnings falter .

Which Sectors Held Up?

Despite the Nasdaq’s sharp decline, market breadth was remarkably positive, mirroring the pattern seen throughout this earnings season. Nine of the S&P 500’s 11 sectors closed higher .

Healthcare and real estate led gains, rising 2.4% and 2.2% respectively, as investors rotated toward defensive positioning . Apple gained 1.48% and Meta added 1.96%, providing some counterweight to Alphabet’s collapse . Amazon, however, fell 4.25% ahead of its earnings report .

What Are Treasury Yields and the VIX Saying?

The 10-year Treasury yield hovered near 4.93%, close to seven-week lows, as the tech selloff drove safe-haven flows into government bonds . The yield has declined 0.364 percentage points this month, reflecting growing demand for duration amid equity volatility .

The CBOE Volatility Index (VIX) rose 1.7% to 17.20, signaling modestly elevated anxiety but not outright panic .

What’s Next for Investors?

All eyes are on Apple and Amazon, which reported after Thursday’s close. Their results—particularly Amazon’s AWS cloud growth and capex guidance—will determine whether the Alphabet-driven selloff represents a sector-specific repricing or the start of a broader AI correction.

Investors are also digesting Friday’s Employment Cost Index data, expected to show labor cost growth of 0.8%, down slightly from the prior 0.9% . The reading is a key inflation indicator for the Fed, which held rates steady on Wednesday but signaled that further tightening remains possible.

As one strategist put it: “The market is no longer rewarding AI spending blindly. It wants proof of monetization, and Alphabet didn’t deliver that” .
