S&P 500 Overall Market
AI capex sticker shock and an Iran-driven oil spike are colliding to break the two pillars equity bulls were leaning on: cheap money and unlimited mega-cap cash flow.
Alphabet and Tesla kicked off tech earnings season Wednesday with a message the market didn't want to hear: the AI buildout is getting more expensive, not less, and free cash flow is the collateral damage. Alphabet posted negative FCF of $5.9 billion versus positive $25 billion a year ago, while lifting 2026 capex guidance to $195-205 billion from $180-190 billion and warning of further increases in 2027; Tesla's FCF swung to a $1.1 billion deficit as capex jumped 142% to $5.79 billion. Shares fell roughly 3-4% in after-hours trading despite both companies beating on revenue, a classic
Tesla's headline revenue of $28.24 billion beat the Street's $25.71 billion estimate, but the internals were ugly: adjusted EPS of 33 cents missed the 51-cent consensus, gross margin slid to 16.8% from 17.2% a year ago against a 19.4% estimate, and operating margin collapsed to 1.4% from 4.1%. Free cash flow turned negative for the first time in years, a $1.1 billion deficit versus $1.44 billion generated just last quarter, as capex surged 142% year-over-year to fund Cybercab, Optimus, and a Texas AI-chip fab that Musk calls the

Alphabet lifted 2025 capex to $195–205 billion from $180–190 billion and flagged further increases in 2027, even as Google Cloud revenue jumped 82% to $24.8 billion and cloud margins expanded to 35.6% from 20.7% a year ago. Tesla's capex surged 142% year-over-year to $5.79 billion in the quarter, with management guiding to over $25 billion for the full year as Musk pitched Optimus and chip production as the payoff. The market's reaction—punishing a company that just posted the largest quarterly profit in corporate history, $112.1 billion—tells you positioning had gotten stretched long AI-infrastructure beneficiaries into earnings, and gamma is now working against the crowd on any capex-guidance miss. Expect elevated realized vol in mega-cap tech names through the rest of earnings season as investors demand visibility on ROIC, not just top-line AI narrative, with the index's breadth increasingly hostage to a handful of hyperscaler capex decisions.
