Microsoft this week reported third-quarter fiscal year 2026 results for the period ended March 31, 2026, showing a rebound in search advertising revenue and an AI business that surpassed a $37 billion annual run rate. The numbers matter to anyone working in digital advertising, where the health of Microsoft's platform determines budgets, inventory prices, and the direction of AI-driven search tools across Bing, Edge, and LinkedIn.

Search advertising rebounds after two soft quarters

Search advertising revenue excluding traffic acquisition costs grew 12% year-over-year in Q3 FY26, or 9% in constant currency. That figure compares to 10% GAAP growth in the previous quarter and 21% growth recorded as recently as Q3 FY25. The rebound is a meaningful shift after two quarters in which growth had decelerated sharply from the rates maintained throughout most of fiscal year 2025.

According to Amy Hood, executive vice president and chief financial officer of Microsoft, the growth was "driven by higher volume and revenue per search across Edge and Bing." She did not attribute the recovery to a single factor, but the phrasing - volume and rate per search together - suggests both demand and yield improved in the quarter.

The advertising line sits inside the More Personal Computing segment, which generated $13.2 billion in total revenue during the quarter, down 1% year-over-year and down 3% in constant currency. That top-line decline was driven by Xboxand Windows OEM and Devices, both of which fell. Xbox content and services revenue declined 5% (down 7% in constant currency), while Windows OEM and Devices declined 2% (down 3% in constant currency). Search advertising was the only growth driver in the segment during the period.

LinkedIn grows 12%, B2B advertising holds firm

LinkedIn revenue grew 12% year-over-year in Q3 FY26, or 9% in constant currency. According to Microsoft's earnings materials, growth was recorded across all lines of business. LinkedIn now has 1.3 billion members according to the earnings transcript, with CEO Satya Nadella describing it as "the leading B2B sales and advertising channel for large and small businesses."

For advertising professionals operating in B2B, LinkedIn's performance matters because the platform carries pricing power that few alternatives can match. Prior PPC Land coverage of Q2 FY26 noted LinkedIn revenue growing 11% GAAP and 10% in constant currency that quarter, so the Q3 acceleration to 12% represents sequential improvement. Nadella also disclosed that LinkedIn's agentic products in Talent Solutions - tools designed to help hirers automate sourcing, screening, and message drafting - have surpassed a $450 million annualized revenue run rate.

The AI business and what it means for the ad stack

The figure that drew the most attention was the AI business crossing a $37 billion annual revenue run rate, up 123% year-over-year. According to Nadella, "Our AI business surpassed an annual revenue run rate of $37 billion, up 123% year-over-year." That growth rate reflects the rapid commercial uptake of Copilot products across Microsoft's enterprise base and, increasingly, consumer surfaces.

For the advertising community, the AI expansion matters in several concrete ways. Microsoft 365 Copilot paid seats now number over 20 million, growing 250% year-over-year and representing Microsoft's fastest seat growth since launch. Nadella described this as a "record quarter for Microsoft 365 Copilot seat adds." The scale of Copilot's enterprise penetration indicates that the surfaces where Microsoft Advertising can place ads - Bing, Edge, and Copilot itself - are becoming significantly more trafficked.

Bing's monthly active users reached 1 billion for the first time during the quarter. That milestone, cited by Nadella in the earnings transcript, marks a meaningful threshold for advertisers estimating reach on the platform. Edge continued gaining browser share, which Nadella said has occurred for 20 consecutive quarters. More users in Edge means more impressions served through Microsoft's search advertising network.

Microsoft's research published in August 2025 had already demonstrated that Copilot generates 73% higher click-through rates and 16% stronger conversion rates compared to traditional search advertising, with customer journeys 33% shorter. The Q3 FY26 numbers suggest that these performance dynamics are translating into real advertiser spending growth.

Azure growth at 40% drives the cloud business

Azure and other cloud services revenue grew 40% year-over-year in Q3 FY26 (39% in constant currency), maintaining the trajectory from the prior quarter. The Intelligent Cloud segment - which houses Azure - reported $34.7 billion in revenue, up 30% year-over-year and 28% in constant currency. Operating income for Intelligent Cloud was $13.8 billion, with an operating margin of approximately 40%.

According to Hood, Azure results "were ahead of expectations, as we delivered capacity earlier in the quarter enabling increased consumption across both AI and non-AI services." She added that strong customer demand across workloads, customer segments, and geographic regions "continues to exceed available capacity." That supply constraint is notable: Microsoft is physically limited in how fast it can grow Azure revenue, not limited by demand.

The Cosmos DB database service grew 50% year-over-year, driven by AI application workloads. Microsoft now has 35,000 paid Fabric customers, up 60% year-over-year, and the amount of data in Fabric OneLake increased nearly 4X year-over-year. Over 15,000 customers now use both Azure AI Foundry and Fabric, also up 60% year-over-year, as companies connect agents to operational, analytical, and unstructured data in a unified layer. These figures matter to advertisers and agencies building audience data infrastructure on Microsoft's cloud stack.

Microsoft Cloud and capital expenditure

Microsoft Cloud revenue overall reached $54.5 billion in Q3 FY26, up 29% year-over-year (25% in constant currency). The gross margin on cloud was 66%, down year-over-year due to heavy AI infrastructure investment. According to Hood, "Company gross margin percentage was 68%, down year-over-year, driven by continued investment in AI infrastructure and growing AI product usage."

Capital expenditure reached $31.9 billion in the quarter, or $30.9 billion in cash paid for property, plant, and equipment. For the nine months ended March 31, 2026, Microsoft spent $80.1 billion on property and equipment additions. Roughly two thirds of Q3 capex was for short-lived assets, primarily GPUs and CPUs. The remainder went toward long-lived datacenter infrastructure.

Nadella offered detail on the pace of buildout: the company added one gigawatt of capacity in Q3 alone, has reduced dock-to-live times for new GPUs in major regions by nearly 20% since the start of the calendar year, and brought its Fairwater datacenter in Wisconsin online six weeks ahead of schedule. GPU inference throughput across Copilot improved 40% through software and hardware optimization. The Maia 200 AI accelerator, which Microsoft says offers over 30% improved tokens per dollar compared to the previous generation, went live in Iowa and Arizona datacenters during the quarter.

Overall financial results

Total revenue for Q3 FY26 was $82.9 billion, up 18% year-over-year (15% in constant currency). Operating income was $38.4 billion, up 20% (16% in constant currency). Net income was $31.8 billion, up 23% on a GAAP basis. Diluted earnings per share reached $4.27, up 23% GAAP.

According to Hood, "We delivered results that exceeded expectations across revenue, operating income, and earnings per share, reflecting strong execution and growing demand for the Microsoft Cloud."

The Productivity and Business Processes segment, which includes Microsoft 365, LinkedIn, and Dynamics 365, generated $35.0 billion in revenue, up 17% (13% in constant currency). Operating income for this segment was $21.0 billion, with an operating margin of 60%. Dynamics 365 grew 22% (17% in constant currency).

Microsoft 365 Commercial cloud revenue grew 19% (15% in constant currency), ahead of expectations. Microsoft 365 Consumer cloud revenue grew 33% (29% in constant currency), driven by average revenue per user growth. Microsoft 365 Consumer subscribers now total nearly 95 million.

The commercial remaining performance obligation - the value of contracted future revenue not yet recognized - rose to $627 billion, up 99% year-over-year. Roughly 25% of that amount, or approximately $157 billion, will be recognized in the next 12 months, up 39% year-over-year. These contract figures give advertisers and partners a signal of how committed enterprise customers are to Microsoft's platform over the next several years.

Cash flow from operations was $46.7 billion for the quarter, up 26% year-over-year. Free cash flow was $15.8 billion after accounting for capital expenditures. Microsoft returned $10.2 billion to shareholders through dividends and share repurchases.

What this means for the advertising community

Several signals from Microsoft's Q3 FY26 results carry direct consequences for people managing advertising budgets on the platform.

The recovery in search advertising from 10% to 12% suggests that the deceleration following the fiscal year 2025 record pace may be stabilizing rather than continuing downward. Search advertising ex-TAC has now grown at 12% two quarters running against a prior-year that included 21% growth, indicating the comparison base is no longer worsening.

LinkedIn's acceleration to 12% growth reinforces its standing as the primary channel for B2B digital advertising, a position confirmed repeatedly by Microsoft's own financial performance. The platform's integration with Epsilon's identity resolution and its expanding audience targeting options make it increasingly central to B2B campaigns.

The Bing 1 billion monthly active user milestone, if sustained, represents a meaningful change in the addressable audience for Microsoft Advertising campaigns. That figure arrived alongside the news that Copilot queries per user grew nearly 20% quarter-over-quarter. Higher query volume per user means more ad auction opportunities per user, which generally expands inventory available to search advertisers without requiring new user acquisition.

At the same time, advertisers using Microsoft's platform should be aware of the API transition underway. Microsoft Advertising is retiring its legacy SOAP API by January 31, 2027, with new features exclusive to the REST API from October 1, 2026. Any tool or platform managing campaigns programmatically through the SOAP interface needs to be assessed against those deadlines.
