Alphabet Q4 2025: Expanding search capabilities and AI adoption

Alphabet’s focus on AI infrastructure is translating into measurable revenue gains across its core platforms. By leveraging enhanced intent recognition, the company has begun capturing value from complex, conversational queries, expanding the overall addressable market for Search advertising. Enterprise and individual demand for AI plans across Google Cloud and YouTube continue to increase.

In 2025, the annual revenue of each of Alphabet’s 14 product lines surpassed US$1 billion. Revenue from YouTube across ads and subscriptions for the full year exceeded US$60 billion across. Google Cloud’s annual revenue run rate exceeded US$70 billion during the year. In 2025, Alphabet’s overall revenues increased 15.1% year-on-year to US$402.8 billion.

Operating income increased 16.0% year-on-year to US$35.9 billion during the quarter, and operating margin dropped from 32.1% to 31.6% over the same period. While Google Cloud’s operating margin expanded from 17.5% to 30.1% year-on-year, Alphabet’s overall margin was tempered by a one-time US$2.1 billion charge. This expense stemmed from stock-based compensation following Waymo’s US$16 billion investment round and subsequent revaluation. Net income grew 29.8% to US$34.5 billion due to unrealised gains in non-marketable equity securities. The company was in a net cash position of US$80.3 billion. The company spent US$5.5 billion on share buybacks and US$2.5 billion on dividend payments.

Google Search saw growth across all major verticals, led primarily by the retail sector. YouTube ad revenue was driven by direct response momentum, particularly as small and medium-sized advertisers increasingly adopt AI-powered Demand Gen advertising campaigns. Year-over-year growth in brand advertising on YouTube slowed following the high spending of the 2024 US election cycle.

The growth in Google subscriptions, platforms, and devices was due to robust growth in Google One and YouTube subscriptions, particularly YouTube Music and Premium.

Google Cloud Platform outperformed Google Cloud’s overall revenue growth, driven by sustained demand for enterprise AI infrastructure and the adoption of Gemini 3. This momentum was reflected in a backlog that surged 55% quarter-on-quarter and more than doubled year-on-year to US$240 billion, while Google Cloud operating income more than doubled year-on-year to US$5.3 billion. Workspace also achieved double-digit growth through increases in both seat count and average revenue per seat. Supporting this scale is a hybrid compute stack of NVIDIA GPUs and in-house TPUs, which optimises performance and cost across the Cloud business.

As revenue from Other Bets declined 7.5% year-on-year in Q4 2025, the segmental operating loss widened from US$1.2 billion to US$3.6 billion.

Capital expenditures (CapEx) totalled US$27.9 billion and US$91.4 billion in Q4 2025 and 2025 respectively. CapEx is anticipated to approximately double to reach between US$175 billion and US$185 billion in 2026 as demand continues to outpace supply amid foreign exchange tailwind. 60% of its capex will be allocated to servers and the remainder to data centres and networking equipment, which carry depreciation periods exceeding 40 years. Half of the company’s machine learning compute is designated for the Cloud business

Alphabet is acquiring Intersect that develops large-scale solar and battery energy storage system at US$4.8 billion to solve its energy bottleneck issue.

Gemini 3 adoption is the fastest in Google’s history, with first-party models now processing over 10 billion tokens per minute via direct API use. Revenue from generative AI products grew nearly 400% YoY in Q4 2025, with more than 120,000 enterprises onboarded and Gemini Enterprise surpassing 8 million paid seats.

Commercial traction continues to scale across both consumer and ads ecosystems. The Gemini app now exceeds 750 million MAUs, while advertisers generated nearly 70 million creative assets in a single quarter. Serving unit costs fell 78% in 2025, supporting long-term margin expansion as AI usage scales.

Google Search

Google Search reached record usage in Q4 2025 as Gemini 3 integration across AI Overview and AI Mode enhanced user experience and drove higher engagement. AI queries are becoming more conversational and increasingly multimodal, spanning text, voice, and image inputs.

Google is piloting Direct Offers and native checkout within AI Search, embedding discounts and enabling purchases directly on-platform — extending monetisation from discovery to transaction.

YouTube Ads

According to Nielsen, YouTube has been the leading streaming service in the U.S. living room for nearly three years. The consumption of podcasts on connected TVs surged 75% year-on-year in October 2025, reaching over 700 million hours.

YouTube Shorts now generates over 200 billion daily views, with Shorts revenue per watch hour surpassing that of traditional videos in several countries, including the US. Management is now prioritising commerce integration by incorporating shoppable formats directly into Shorts (and potentially living room formats in the future), following the pilot of shoppable YouTube Mastheads during the 2025 Cyber 5 shopping period.

Google subscriptions, platforms, and devices

Google surpassed 325 million paid subscriptions, led by Google One and YouTube Premium. YouTube’s subscription revenue growth was largely driven by YouTube Music Premium. Meanwhile, YouTube Premium Lite is successfully converting price-sensitive users, while NFL Sunday Ticket has reached its highest paid subscriber count to date. In addition to a new lower-priced sports tier, YouTube TV is planning over 10 genre-specific packages to offer more flexible and affordable options.

In collaboration with Samsung, Alphabet is integrating Gemini into a vast range of consumer tech, from Galaxy devices and XR headsets to smart home appliances. This growth is anchored by a strong hardware roadmap, including the upcoming launch of the Pixel 10a.

Google Cloud

Despite being capacity-constrained, Google Cloud continued to acquire new contracts, and secured larger contracts from existing customers. In 2025, Google Cloud’s large-scale deals (over US$1 billion) exceeded the total from the previous three years combined. Nearly 75% of customers now utilise Google’s vertically optimised AI stack—spanning chips, models, and agents—with these users typically adopting 1.8x more products than non-AI customers. There is a notable time delay between CapEx and that capacity actually becoming available.

Revenue from AI solutions built by independent software vendors rose nearly 300% year-on-year, while commitments from top software partners grew 16x. Notably, Google is now Apple’s cloud provider, collaborating to develop the next generation of Apple Foundation Models using Gemini technology.

Other Bets

Waymo raised US$16 billion in its latest fundraising round, its largest investment to date. As of December 2025, the autonomous robotaxi service has delivered over 20 million fully autonomous trips and currently provides over 400,000 rides each week. Waymo was recently launched in Miami and will be expanded across the US, the UK, and Japan.

Key analyst questions

Alphabet primarily builds its own data centres to optimise facilities for AI workloads, while roughly 50% of its code is now generated by AI agents, accelerating development with human review.

Search revenue growth was driven by retail, finance, and health sectors. CEO Sundar Pichai noted that AI-driven features have not cannibalised existing Search usage, but rather represent a primary growth opportunity. Automation tools like AI Max and Performance Max are widely adopted by small and medium businesses, generating millions of creative assets and improving returns through more precise ad targeting.

While the Gemini App focuses on user growth, management plans to introduce ads selectively. Management intends to integrate ads into these new AI experiences only when they can provide helpful commercial value, noting that they are not rushing this transition.

The Universal Commerce Protocol is being integrated with Gemini, enabling AI-driven transactions and a native checkout experience for select merchants. While a user on YouTube moving from ad-supported to a paid subscription slightly reduces ad revenue, the company views this shift as a net positive for the overall business.

The fifth perspective

Alphabet’s 2025 results demonstrate that its core platforms are evolving with generative AI rather than being displaced by it. Gemini is enhancing search depth and monetisation, while YouTube is expanding commerce and subscription pathways. Supported by a robust Cloud backlog and improving AI unit economics, these investments are now translating into durable, long-term growth.
