Alphabet announces $205 billion AI infrastructure capex, exceeding analyst expectations despite stock decline.

Alphabet Inc. delivered a second-quarter earnings report that should have been a victory lap. Revenue surged 24% to $119.8 billion, Google Cloud sales exploded 82% higher, and net income, swollen by paper gains on its SpaceX and Anthropic stakes, hit a staggering $112.1 billion. Instead, shares tumbled as much as 7% in early trading Thursday, wiping out months of gains, after the company raised its 2026 capital spending forecast to as much as $205 billion and reported its first quarter of negative free cash flow since going public in 2004.

The sell-off underscores a brutal new reality for Big Tech: delivering monster growth is no longer enough. Investors are now demanding proof that the hundreds of billions of dollars pouring into artificial intelligence infrastructure will eventually generate monster returns, too. On that front, Alphabet's message was clear — the spending spree is just getting started.

By almost any conventional yardstick, Alphabet's Q2 was exceptional. Revenue of $119.8 billion sailed past the $117 billion consensus estimate, marking the twelfth consecutive quarter of double-digit growth. Operating income jumped 30% to $40.8 billion, while operating margins expanded two percentage points to 34%.

The star of the show was Google Cloud. Revenue in the segment rocketed 82% year-over-year to $24.8 billion, and operating income more than tripled to $8.8 billion. The cloud backlog swelled to $514 billion, a figure that reflects signed contracts for future services and speaks to insatiable enterprise demand for AI computing power.

"We continue to believe that our full stack approach to AI is delivering real, measurable value," CEO Sundar Pichai said on the earnings call. He noted that the Gemini app now has 950 million monthly active users and that roughly 90% of Fortune 100 companies have adopted the enterprise version of the model.

The core advertising business also showed resilience. Search revenue grew 17% to $63.3 billion, defying predictions that AI chatbots would eat into Google's search dominance. YouTube ad revenue rose 13% to $11.1 billion. AI Overviews and AI Mode, Pichai said, are driving more search activity and continue to send billions of clicks to websites each week.

The headline earnings number, however, contained a massive caveat. Reported diluted earnings per share came in at $9.11, seemingly obliterating the $2.88 consensus. Buried in the earnings release was a disclosure that reshaped the entire profit picture: $99 billion in unrealized and realized gains on equity securities, contributing $6.26 of the $9.11 in earnings per share. The windfall came primarily from two investments that saw their valuations skyrocket during the quarter.

SpaceX, in which Google held roughly a 6% stake at the end of 2025, went public on June 12 at a valuation of approximately $1.77 trillion — a dramatic leap from its $400 billion private-market valuation a year earlier. Alphabet's filing revealed its SpaceX holdings were worth $94.1 billion, with $80 billion subject to short-term sale restrictions and another $14.1 billion under lockup through the third quarter of 2027.

Anthropic, the AI startup Google first backed in April 2023 with a $300 million investment, saw its private-market valuation nearly triple from $350 billion to $965 billion. Google's total investment in Anthropic has grown to $13.3 billion, with commitments of up to $30 billion more.

Strip out those paper gains, and Alphabet's adjusted earnings were roughly $2.85 per share — slightly below the $2.89 analysts had expected.

The number that really rattled investors was $44.9 billion — Alphabet's capital expenditures for the quarter, roughly double the prior-year period. That figure exceeded the $39.1 billion in operating cash flow the company generated, pushing free cash flow to negative $5.9 billion. It was the first negative free cash flow quarter in Alphabet's history as a public company.

"We had negative free cash flow of $5.9 billion in the second quarter," CFO Anat Ashkenazi told analysts. She raised the full-year capex forecast to $195 billion to $205 billion, up from the previous range of $180 billion to $190 billion. It was the second upward revision in three months. Ashkenazi also warned that 2027 spending would increase "significantly." About 60% of second-quarter capex went to servers, with the remaining 40% directed toward data center construction and related infrastructure.

The scale of the spending is staggering even by tech industry standards. Capital expenditures now consume 37.5% of every dollar Google collects in revenue, the highest share in company history. Over the trailing twelve months, capex totaled $132.4 billion, a 98% increase.

To fund this buildout, Alphabet has tapped capital markets aggressively. It raised $49.6 billion through stock and mandatory convertible preferred issuance during the quarter, plus $20.3 billion from senior notes. Long-term debt has more than doubled since December to $98.2 billion. Notably, the company repurchased no stock in Q2, compared with $13.2 billion in buybacks a year earlier.

The spending trajectory prompted a flurry of price-target cuts from analysts who otherwise remain bullish on the stock. Oppenheimer's Jason Helfstein maintained his Buy rating but lowered his target to $400 from $445, citing weaker Services margins and higher financing costs. He noted that AI products like Gemini "are not yet generating significant revenue" and that Google Cloud will likely rely more on third-party computing capacity in the second half, pressuring margins.

Piper Sandler's Thomas Champion cut his target to $395 from $445 while reiterating a Buy. UBS analyst Stephen Ju lowered his target to $379 from $400, keeping a Hold rating, and said rival Amazon offers a better risk-reward profile.

On TipRanks, Alphabet maintains a Strong Buy consensus based on 29 Buy and five Hold ratings. The average price target of $437.79 implies nearly 28% upside from current levels.

Alphabet's sell-off rippled across the sector. Meta Platforms shares fell roughly 3% and Microsoft eased 1% in sympathy. The moves reflect growing unease about the combined capex of the four hyperscalers — Alphabet, Microsoft, Amazon, and Meta — which is expected to approach $725 billion to $800 billion in 2026.

"Tech giants are spending on AI like there's no tomorrow, but investors have realized it's tomorrow they care about," said Nic Puckrin, cross-asset analyst and founder of Coin Bureau. "They want to see today's spending turn into tomorrow's earnings, but so far there's no sign of this."

The technical picture for Alphabet has also deteriorated. The stock closed below its 100-day moving average for the first time since April on Wednesday, and analysts at JPMorgan warned that a failure to hold the 200-day moving average around $323 could trigger a "more pronounced position unwind" across the AI theme.

With Microsoft, Apple, Meta, and Amazon all set to report earnings in the coming week, Alphabet's reception may prove a preview of what awaits them if their own AI investments fail to impress. Despite the near-term anxiety, many investors and analysts argue the spending is not speculative — it is chasing confirmed demand. Google Cloud's $514 billion backlog suggests customers are lining up faster than Alphabet can build data centers.
