Alphabet Stock: Record-Breaking Growth Meets AI Ad Risk
Alphabet (NASDAQ: GOOGL, GOOG) just delivered one of the strongest quarters in its history — its first-ever $100 billion quarter. Revenue for Q3 2025 climbed 16% year over year to $102.3 billion, while EPS surged 35% to $2.87. Google Services — which includes Search, YouTube, Google Play, and hardware — generated $87.1 billion, up 14%. Google Cloud was the standout, accelerating 34% to $15.2 billion, with AI infrastructure and generative AI solutions leading demand.
Operating margin came in at 30.5%, but excluding the $3.5 billion EU antitrust fine, core operating margin improved to 33.9%, demonstrating Alphabet’s ability to boost profitability even while investing aggressively in AI. Net income increased 33%, helped by a $12.8 billion gain from equity investments.
AI Is Driving Growth — But Could Reshape Search Economics
Alphabet’s AI strategy is now fully embedded across Search, YouTube, and Cloud. The rollout of AI Overviews and AI Mode in Search is the biggest transformation to the platform since its inception. Gemini, Google’s flagship model, now handles “7 billion tokens per minute” through APIs and has over 650 million monthly users.
However, this shift also introduces new uncertainty. If AI-generated answers reduce the need for users to click links, that could impact the core ads business that funds 80% of Alphabet’s revenue.
According to Kevin A. Thomas, a CFA and founder of Omniga.ai, AI-powered search demands far more personalized data to return meaningful results — which raises both strategic opportunities and privacy risks. He notes that while AI helps Google retain users by offering instant answers, it also risks reducing ad impressions if fewer people click through to websites. Alphabet must ensure AI enhances ad relevance rather than bypassing it.
Cloud and Subscriptions Are Becoming Real Profit Engines
Google Cloud continues to be the fastest-growing segment. Revenue grew 34% year over year, and backlog increased to $155 billion, a sign of long-term AI and enterprise demand. AI infrastructure, training models, and sovereign cloud offerings are all accelerating adoption. Cloud is now profitable on an operating basis — a stark contrast from two years ago when it was still in the red.
Meanwhile, Alphabet now has over 300 million paid subscriptions, led by YouTube Premium and Google One. These high-margin recurring revenues help diversify the company beyond ads. YouTube ads themselves remain healthy — benefitting from Shorts monetization and connected TV growth.
Capex Surge: AI Is Expensive
Alphabet expects full-year 2025 capital expenditures to reach $91–$93 billion, the highest in company history. The majority will be directed toward GPUs, data centers, AI custom chips (TPUs), and global expansion of cloud infrastructure.
This is the trade-off investors must evaluate: Alphabet is transitioning from a digital advertising company to a capital-heavy AI and infrastructure provider. Margins remain strong for now, but higher depreciation and energy costs could pressure profitability in 2026 and beyond.
AI models need vast datasets, more protected cloud environments, and stronger information security frameworks. The company must scale AI while avoiding privacy concerns, regulatory backlash, or trust erosion — especially in Europe, where Alphabet continues to face regulatory scrutiny.
Alphabet’s Q3 2024 results reveal an impressive 15% revenue growth to $88.3 billion, driven by robust ad revenue and a 35% surge in Google Cloud. With strong gains across Search, YouTube, and AI-powered enterprise solutions, Alphabet remains a leader in digital advertising and next-gen tech, pushing margins higher amidst fierce competition.
Alphabet Shines in Q3: Strong Ad Growth and Cloud Surge Propel Revenue
Alphabet’s Q3 2024 earnings showcased robust performance, with a 15% year-over-year (YoY) revenue increase to $88.3 billion, or 16% in constant. This growth underscores Alphabet’s enduring strength in digital advertising and expanding cloud services. Google Services, covering Search, YouTube, subscriptions, platforms, and devices, brought in $76.5 billion, up 13% YoY.
Similarly, demand across Search and YouTube remains strong, with YouTube’s total ad and subscription revenue surpassing $50 billion for the past four quarters, a significant milestone. This growth continues despite rising competition from the likes of TikTok. Revenue at Google Cloud topped 35% to $11.4 billion, underlining Alphabet’s progress in enterprise technology and AI-driven solutions, including its Generative AI offerings. Alphabet’s operating income increased by 34%, with the operating margin up from 28% to 32%, reflecting growth with operational efficiency.
The core of its revenue driver-its advertising business’s core revenue saw Google Search and other ad revenues rise to $49.4 billion. In comparison, YouTube ads grew to $8.9 billion, recovering from earlier ad spending cuts. As CEO Sundar Pichai noted, the company’s emphasis on AI-driven search improvements enhances user engagement and ad relevance. With ads and subscriptions collectively hitting $50 billion over the last four quarters, YouTube’s significant growth solidifies its video advertising position. In contrast, Google Network revenue, contributing $7.5 billion, recorded a slight 1.6% decline YoY, pointing to a mature growth phase in this segment.

The Google Cloud segment continues to stand out, maintaining a strong double-digit growth trajectory and increasing Alphabet’s market share in the cloud space alongside Amazon and Microsoft. Cloud revenue grew 35% YoY, appealing to enterprise clients through advanced AI and analytics solutions. Operating income for Cloud reached $1.95 billion, a substantial leap from $266 million in Q3 2023, reflecting economies of scale and higher-margin services within Google Cloud Platform. Alphabet’s growth within the Cloud, driven by its focus on AI infrastructure and data capabilities, contributes meaningfully to Alphabet’s revenue diversification, strengthening its position as a critical player in the AI and cloud technology markets.
Rising Costs and Heavy AI Investment: Alphabet’s Path to Long-Term Growth Under Pressure
On the cost side, Alphabet’s Traffic Acquisition Costs (TAC) rose 6.1% YoY to $13.7 billion, representing the expenses tied to driving platform traffic. Capital expenditures (CapEx) increased by 71.9% to $13.06 billion, with a primary focus on AI infrastructure investment. While these CapEx levels support Alphabet’s positioning in AI, they present challenges in profitability and ROI, particularly given the high investment relative to Google Cloud’s revenue.
According to the financial planner Steven Kibbel, Alphabet’s strategic focus on boosting AI-related capital expenditures presents both growth opportunities and margin pressures. While the 71.9% CapEx increase underscores Alphabet’s commitment to AI leadership, rising Traffic Acquisition Costs (TAC) could strain short-term profitability. This investment could drive future innovation and revenue streams but risks near-term shareholder value as Alphabet prioritizes long-term growth. Success hinges on Alphabet’s ability to monetize AI advancements effectively and increase profitability amidst high spending.
Alphabet’s focus on operational efficiency has paid off, with operating income increasing 34% to $28.5 billion. The operating margin rose to 32%, up from 28% a year earlier, reflecting tighter cost control even as total expenses rose 8% to $59.75 billion. Alphabet’s bottom line benefited further from an “other income” gain of $3.2 billion, compared to a $146 million expense a year ago, reflecting improved financial performance beyond operating revenue.
Analysts have noted Alphabet’s success in navigating core and emerging segments. Lucas Ma of Envision Research observed that Alphabet’s solid ad revenue and substantial Cloud growth indicate its “wide moat” and growing AI momentum. Similarly, analyst Rob Isbitts highlighted Alphabet’s stock resilience and technical momentum, noting the stock’s breakthrough above resistance levels. This performance demonstrates that Alphabet remains a strong player, balancing steady growth with innovation in AI, solidifying its long-term position in both advertising and enterprise tech markets.
Lastly, valuation-wise, Alphabet’s forward P/E and PEG ratios remain elevated, signaling potential limits on the near-term upside. However, Alphabet’s balanced growth in revenue, strong cloud momentum, and innovation-focused model position it as a solid long-term hold for investors seeking stability amid valuation constraints.
Takeaway
Alphabet’s Q3 2024 earnings showcased strong growth with a 15% YoY revenue increase, led by solid ad revenue and a 35% surge in Google Cloud. Operational efficiency improvements boosted operating income by 34%, raising margins to 32%. While heavy AI-focused CapEx supports long-term innovation, rising TAC and relatively high valuations could pressure near-term profitability. Analysts see Alphabet’s wide moat in advertising and growing momentum in AI and cloud as strengths, affirming its position as a solid long-term hold despite some valuation constraints.
