AI Drives Significant Acceleration in Alphabet's Cloud Business; Citi Reiterates Buy Rating

Overview

This report is Citi's first-take review of Alphabet's 2Q26 results. Alphabet's results were better than expected, driven mainly by revenue growth in search and cloud. Total revenue was US$119.8 billion, up 23% year over year on a constant-currency basis, while operating profit was US$40.8 billion with a 34.0% margin; both were slightly above consensus. The report emphasizes AI query usage, GCP demand, TPU sales, computing investment, Gemini model progress, AI search monetization, and the capital expenditure outlook.

Core views

Citi's core view is that Alphabet's search advertising business remains resilient, YouTube advertising was better than expected, and Google Cloud has clearly reaccelerated on TPU and Gemini demand. The significant increase in backlog supports a valuation premium relative to the market and Alphabet's own historical range. Although 2Q capital expenditures rose to US$44.9 billion, they were broadly in line with Citi's forecast and viewed as part of an acceleration in technology infrastructure investment. Citi therefore reiterates its Buy rating.

Analysis framework

The report uses an earnings quick-review framework, comparing 2Q26 actual revenue, segment revenue, operating profit, margins, EPS, and capital expenditures with FactSet consensus and Citi's forecasts, while assessing the investment conclusion based on cloud backlog, AI demand, search and YouTube advertising growth, capital expenditures, and valuation multiples.

Methodology notes

  Actual Results Relative to Consensus Expectations

  By comparing deviations in revenue, operating profit, segment revenue, and margins relative to consensus expectations, the report assesses the sources and quality of the earnings beat.

• Valuation methodsforward_pe_multiple

  Forward P/E Valuation

  The US$447 target price is based on approximately 28x 2027E GAAP EPS of US$15.90, with Citi believing that cloud reacceleration and AI product momentum support a valuation premium.

  AI-Driven Cloud Demand and Backlog

  Google Cloud revenue growth of 81.8% year over year and backlog growth of 385% are used as important indicators of the strength of TPU, Gemini, and enterprise cloud demand.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• GOOGL.O

  Covered company stock; Citi reiterates its Buy rating and sets a US$447 target price.

  Strengths

  Resilient search advertising, better-than-expected YouTube performance, significantly better-than-expected Google Cloud revenue and margin, and rapid backlog growth driven by AI-related demand.

  Weaknesses

  Google Services operating margin was below Citi's 43.5% forecast, while capital expenditures continued to rise.

  Comparison

  Total revenue was approximately 2% above consensus and operating profit approximately 1% above consensus; Google Cloud revenue was approximately 11% above consensus, and cloud operating profit also exceeded consensus.

  Risks

  Slower advertising demand, intensifying competition, lower-than-expected internet advertising spending, and antitrust and data privacy regulatory pressure.

Impact & implications

The report's implications for Alphabet's share price are broadly positive: search and YouTube indicate healthy online advertising demand, while accelerating Google Cloud revenue and expanding backlog reinforce the support provided by AI infrastructure and model demand for medium- to long-term growth. If AI search monetization, Agentic Commerce, TPU sales, and Gemini model progress continue to materialize, Citi believes the stock can sustain a premium relative to the market and its historical valuation range.

Risks

• Unfavorable macroeconomic or consumer spending trends could weigh on advertising spending.
• Competitive impacts could be greater than Citi expects.
• Internet advertising spending could slow faster than expected.
• Antitrust, data, and privacy-related regulatory pressure could adversely affect company performance.
• Continued increases in capital expenditures could raise market concerns about free cash flow and the pace of investment returns.

What to watch

• Whether AI query usage continues to reach new highs and whether its contribution to search growth is sustainable.
• Drivers of GCP demand, TPU sales progress, and the pace of backlog conversion.
• Computing capacity requirements, technology infrastructure capital expenditures, and subsequent capex guidance.
• Product performance of Gemini 3.5 Pro, 3.6 Flash, and subsequent frontier models.
• Progress on AI search monetization plans and Agentic Commerce.
