[[4]](https://finance.biggo.com/news/US_GOOGL_2026-07-22)
Tesla shares plunged roughly 14% and Alphabet fell about 6% on Wednesday after both companies reported second-quarter earnings that beat revenue estimates but revealed surging AI capital expenditure plans that pushed free cash flow deep into negative territory. The selloff wiped tens of billions of dollars in combined market capitalization in a single session [5].
Tesla posted Q2 revenue of $28.24 billion, up 26% year-over-year and a company record, but capital expenditures jumped 142% to $5.79 billion, resulting in negative free cash flow of $1.09 billion. Non-GAAP earnings per share of $0.33 missed the $0.51 consensus estimate [1].
Alphabet delivered revenue of $119.8 billion, up 24% and ahead of the $117 billion Wall Street consensus, powered by an 82% surge in Google Cloud revenue to $24.8 billion. But the company spent $44.9 billion on capex in the quarter alone — more than double the year-ago figure — and raised its full-year capex outlook to $195-$205 billion, up from prior guidance of $180-$190 billion [2] [4]. The parallel selloffs crystallized a growing tension in public markets: investors are rewarding AI-driven revenue growth but punishing the capital intensity required to sustain it, particularly when free cash flow turns negative.
Tesla: Record Revenue, Collapsing Margins #
Tesla delivered record quarterly vehicle deliveries of 480,126 units, up 25% year-over-year, and crossed $100 billion in trailing twelve-month revenue for the first time. Automotive revenue rose 23% to $20.52 billion, while the Services & Other segment jumped 50% to $4.58 billion [1].
But the bottom line told a different story. GAAP operating income fell 57% to $398 million, compressing operating margin to 1.4% — down from 4.1% a year earlier and a fraction of the roughly 17% Tesla posted at its 2022 peak. Operating expenses rose 47% to $4.35 billion as the company increased spending on AI infrastructure, its robotaxi program, and Optimus humanoid robot production [3].
Free cash flow swung to negative $1.09 billion, compared with positive $146 million a year earlier. Tesla has not generated positive free cash flow in any quarter of 2026. The company's full-year capex guidance stands at $25 billion, roughly 142% above 2025 levels [1] [3].
Alphabet: Cloud Booms, Capex Doubles #
Alphabet's headline numbers were strong across every major revenue line. Google Search revenue rose 17% to $63.3 billion, YouTube advertising climbed 13% to $11.1 billion, and Google Cloud was the standout, surging 82% to $24.8 billion with operating income tripling to $8.81 billion [2] [4].
The company reported net income of $112.1 billion, though analysts noted the headline EPS of $9.11 was inflated by approximately $6-$7 per share in unrealized investment gains from positions in Anthropic and SpaceX. Core operating EPS was closer to $2.90 [6].
Capital expenditures doubled year-over-year to $44.9 billion in the quarter, driving free cash flow to negative $5.9 billion — a stark reversal from positive $10.4 billion a year ago. Alphabet raised its full-year 2026 capex guidance to $195-$205 billion with a $200 billion midpoint, and signaled that 2027 spending would 'increase significantly' beyond that [[2]](https://futurumgroup.com/insights/alphabet-q2-fy-2026-google-cloud-leads-growth-amid-rising-ai-investment/) [4].
Google Cloud's backlog reached $514 billion, up more than $50 billion sequentially. Roughly 90% of Fortune 100 companies now use Gemini Enterprise, and AI Mode surpassed 1 billion monthly active users [4].
Why Investors Sold #
The simultaneous selloffs in two of the market's largest companies underscored investor anxiety about the return profile of AI infrastructure spending. Both Tesla and Alphabet beat top-line expectations, yet both saw free cash flow go negative as capital expenditures overwhelmed operating cash generation.
For Alphabet, the concern is scale: a $200 billion annual capex run rate dwarfs anything the company has previously undertaken, and the promise of even higher spending in 2027 raised questions about how long investors must wait for commensurate returns. The company also suspended its share buyback program, and raised roughly $70 billion in combined equity and debt to finance the buildout [6].
For Tesla, the issue is margin erosion. The 1.4% operating margin became the focal metric for analysts, overshadowing record deliveries and revenue. BYD delivered 557,090 battery-electric vehicles in Q2, exceeding Tesla by approximately 77,000 units, adding competitive pressure to an already compressed margin environment [3].
Prediction markets reflected the bearish sentiment: Polymarket implied a Tesla price target of $341.37, well below the analyst consensus of $425.22 [5].
What's Next #
Tesla's near-term trajectory hinges on whether its AI-adjacent businesses — robotaxi, Optimus, and Full Self-Driving — can begin generating meaningful revenue before margins compress further. Active FSD subscriptions reached 1.48 million, up 56% year-over-year, but NHTSA maintains an open investigation into FSD-related safety incidents [3].
For Alphabet, Google Cloud's 82% growth rate and $514 billion backlog provide the clearest justification for the spending spree. CFO Anat Ashkenazi warned that Cloud will face 'modest margin pressure' in Q3 as the company uses third-party capacity as a bridge while its own data centers come online [4]. The earnings season continues with Meta, Microsoft, and Amazon reporting in the coming days, each of which has its own multi-billion-dollar AI capex program. Their results will determine whether the market's AI spending anxiety is isolated to Tesla and Alphabet or represents a broader repricing of the AI infrastructure trade.
