Pain Points：決算ノイズを除いて読む
- Capex guidance moves faster than revenue recognition. Alphabet raised 2026 capital expenditure (capex) three times in six months — from $175–185B to $195–205B. If you model only top-line beats, you miss why GOOGL fell ~4% after-hours despite a revenue beat.
- GAAP EPS masks the operating story. Q2 diluted EPS of $9.11 includes a ~$99B unrealized gain on equity stakes (Anthropic, SpaceX). Adjusted EPS ~$2.88 is still in line — headline +294% YoY is not the number traders rerate on.
- Model cadence risk is now a balance-sheet story. Gemini 3.5 Pro is months late while OpenAI, Anthropic, and xAI ship July frontier models. Enterprise buyers and AI builders need a framework — not just headlines — to decide whether Google's full-stack bet (models + TPUs + Cloud) still wins.

*GAAP EPS includes ~$99B unrealized equity gains (Anthropic, SpaceX). Adjusted EPS ~$2.88 — in line with estimates.
Google Cloud：四半期のスター +82%
Revenue jumped 82% year-over-year to $24.8 billion, accelerating from 63% in Q1 and 48% in Q4 2025. Operating income surged to $8.8 billion (from $2.8B), pushing cloud operating margin to 35.6%. The $514 billion backlog (up $50B QoQ) gives unusually strong revenue visibility.
- Enterprise AI infrastructure (TPUs, GPU clusters)
- Gemini Enterprise — ~90% of Fortune 100
- Core GCP workloads
- First TPU system sales revenue
- Wiz acquisition — cloud security pipeline
— Sundar Pichai: "Q2 was an amazing quarter, with Alphabet revenues growing 24% year-over-year and Google Cloud revenues accelerating to 82% growth, driven by demand for AI infrastructure and AI solutions."
Search & YouTube：AI がパイを拡大
A common fear: AI Overviews would cannibalize search ads. Q2 suggests the opposite — for now. Google Search & other: $63.3B (+17%); YouTube ads: $11.1B (+13%); total advertising $81.6B. AI Mode has 1B+ MAU; Gemini App 950M MAU; API throughput 22B tokens/min (up from 16B in Q1).
決算 beat なのに GOOGL が下がった理由
Alphabet shares dropped ~4% in after-hours trading to ~$327 despite beating revenue and EPS. Three drivers:
- Capex guidance raised again — July 2026 range $195–205B (was $180–190B in April). Q2 capex alone: $44.9B (+100% YoY). Management flagged 2027 capex significantly higher.
- Free cash flow turned negative: -$5.9B vs +$5.3B a year ago.
- Gemini 3.5 Pro overhang — flagship model delayed while competitors ship monthly.
| Timeline | 2026 Capex Range |
|---|---|
| Early 2026 | $175B – $185B |
| April 2026 (Q1 call) | $180B – $190B |
| July 2026 (Q2 call) | $195B – $205B |
— CFO Anat Ashkenazi: demand signals stronger than a year ago; disciplined ROI framework on AI infrastructure spend.
Gemini 3.5 Pro：遅延しているが終わりではない
Originally expected June 2026. Bloomberg (July 16): months behind because coding performance fell short of internal goals. Google confirms testing with partners; no public launch date. Pichai: already started Gemini 4 development; plans near-monthly model releases. Gemini 3.5 Flash Cyber did launch for security workloads.
Frozen v2：Gemini 専用 AI チップへの賭け
The Information reports Frozen v2 — a server chip embedding parts of Gemini's architecture in silicon. Estimated 6–10× tokens per watt vs current TPUs. Gemini-only scope; complementary to general TPUs. Most TPU system sales revenue expected in 2027.
| Attribute | Detail |
|---|---|
| Design | Embeds parts of Gemini architecture in silicon |
| Efficiency | Est. 6–10× tokens per watt vs current TPUs |
| Scope | Gemini-only (not general-purpose TPU) |
| Production | Smaller initial run; test bed for specialized AI hardware |
| vs TPUs | Complementary, not a replacement |

よくある質問
Google Q2 2026 決算の主要数値は？
Alphabet は Q2 2026 売上高 1,198 億ドル（YoY +24%）、希薄化 EPS 9.11 ドル、Google Cloud 248 億ドル（YoY +82%）を計上。ウォール街予想 1,169 億ドルを上回った。
決算好調なのに GOOGL が下がった理由は？
2026 年 CapEx ガイダンスが 1,950–2,050 億ドルに引き上げ（従来 1,800–1,900 億）、Q2 CapEx 449 億ドル、FCF -59 億ドルとマイナス転換。アフター時間で約 4% 下落。
Gemini 3.5 Pro は遅延している？
はい。パートナー向けテスト中だが公開日未定。Bloomberg はコーディング性能が内部目標に届かず数か月遅れと報じた。
Frozen v2 チップとは？
Gemini アーキテクチャの一部をシリコンに組み込んだ Google 設計の AI サーバーチップ。The Information は現行 TPU 比 6–10 倍の電力効率と報じた。
まとめ
Alphabet's Q2 2026 earnings confirm AI monetization is working — Cloud +82%, Search still growing, Gemini adoption at scale. The market is pricing the cost of staying at the AI frontier, not just the revenue.
For AI builders prototyping on Gemini API or Antigravity, a laptop-only setup means sleep-interrupted eval jobs, commingled GCP keys, and no native Xcode/Fastlane chain for iOS + Agent hybrids. Generic Linux VPS cannot run Apple toolchain tasks. For stable, isolated production loops, renting a VPSMAC M4 Mac cloud node — native macOS, SSH + launchd, elastic memory — is usually more reliable than personal hardware.
