How much did AI drive Amazon's Q2 2025 ad revenue?

Amazon’s Q2 2025 advertising services revenue was $15,694 million, reported on July 31, 2025. The line grew 23% year over year as reported and 22% excluding foreign exchange. Amazon did not disclose an AI-attributed advertising revenue line for the quarter, so the clean answer is: strong ad growth, no reported AI revenue attribution. [1]

That matters because this is the year-ago baseline behind the site’s Q2 2026 Amazon coverage, including Amazon Q2’s AI advertising claims don’t line up, Amazon Q2 Earnings Signal Q3 Ad Cost Pressures for Advertisers, and Does Amazon’s AI spending increase mean higher ad costs?. The source hierarchy is simple: Amazon’s own release sets the record; coverage can help with estimates, market reaction, capex context, and ad-share analysis.

The advertising line before the AI story gets attached

The company-wide quarter was large enough to make almost any platform narrative sound plausible. Amazon reported total net sales of $167.7 billion, up 13%; AWS revenue of $30.9 billion, up 17.5%; operating income of $19.2 billion, up 31%; and net income of $18.2 billion, or $1.68 per diluted share. The advertising services line, however, deserves its own treatment because it outgrew the larger businesses and because its growth basis is easy to blur. [1]

Marketplace Pulse calculated advertising at 9.36% of Amazon’s total revenue in Q2 2025, the highest ad share it had recorded. That is not an Amazon-disclosed operating metric, but it is useful corroborating analysis: advertising was not just getting bigger in dollars; it was taking up more space inside Amazon’s revenue mix. [2]

The acceleration is the part worth preserving. Q2 2025 was not merely another seasonal step up from Q1. It accelerated from Q1 2025’s 19% growth and from Q2 2024’s 20% growth, while Q4 2024 and Q1 2025 had been sitting in the high teens. CNBC also recorded the ad print at $15.69 billion versus a $14.99 billion StreetAccount estimate, which is the difference between “healthy” and “clearly ahead” in a media buyer’s quarterly notes. [3]

Disclosed growth drivers: audience, funnel, CTV, marketplace density

The quarter had enough disclosed advertising drivers that it does not need an AI revenue claim to explain why the line looked strong. PPC Land’s coverage of the call cited Andy Jassy describing an average ad-supported U.S. audience of more than 300 million people and pointing to Amazon’s full-funnel ad offerings. Those are not small inputs. For buyers, “full funnel” changes where Amazon can compete for budget: not only sponsored placements near checkout, but streaming, display, and measurement conversations that used to sit more cleanly with other platforms. [4]

CTV was especially relevant inside the quarter. Amazon and Roku announced a June 2025 deal that connected Amazon DSP access to roughly 80 million U.S. CTV households. Amazon also expanded into Disney’s Real-Time Ad Exchange during the quarter. Neither deal lets anyone calculate a tidy dollar contribution to Q2 ad revenue from the outside, but both belong in the disclosed-driver column before anyone reaches for a vague “AI drove it” explanation. [4]

Then there is the less elegant but very real marketplace layer: Amazon has been making the marketplace more advertising-dense. Marketplace Pulse frames that as part of a broader shift in how much of Amazon’s commerce surface is monetized through advertising and seller services. That is analysis rather than company disclosure, so it should not be treated like a reported segment metric. It still fits the buyer-side reality better than pretending the quarter can be reduced to a single technology cause. [2]

Where AI attribution stops

Amazon almost certainly uses machine learning and AI across pieces of its advertising system. That is different from saying Amazon disclosed how much Q2 2025 advertising revenue was caused by AI. The company did not report an “AI ads revenue” line, an AI-attributed lift percentage, or a disclosed bridge from AI products to the $15,694 million advertising services result. [1]

This is the boundary that protects the number. Later AI ad products, Rufus-native ad-unit discussion, Alexa+ ad scenarios, and July Prime Day performance data should not be pulled backward into Q2 2025 revenue unless a dated source places them there. July Prime Day material belongs to Q3 2025, not the April-to-June quarter. Alexa+ advertising speculation is not booked Q2 advertising services revenue.

The stricter reading is not anti-AI. It just keeps adoption, infrastructure buildout, and reported revenue impact in separate columns. A media buyer can believe Amazon’s ad stack is becoming more automated and still refuse to tell a CFO that AI drove a specific share of Q2 2025 ad growth when Amazon did not disclose that share.

The verifiable AI signal was capex, not ad revenue attribution

The AI-adjacent number that did land in the quarter was on the cost side. CNBC reported CFO Brian Olsavsky’s Q2 2025 capex figure at $31.4 billion and said that pace implied roughly $118 billion for 2025, above the $100 billion forecast Amazon had discussed in February. The Register also highlighted the $31.4 billion capex figure in the context of investor impatience around AI spending. [5][6]

That is a meaningful signal for anyone tracking Amazon’s AI investment curve. It is not a revenue-attribution bridge. Capex can support AWS capacity, fulfillment automation, model training, internal tools, advertising infrastructure, or some mix of those uses. Without a disclosed allocation and without an ads revenue bridge, the honest sentence is narrower: Amazon was spending heavily on AI-related infrastructure while its advertising business was accelerating.

The earnings context is useful, but it should not drown the ad record

The broader earnings reaction came from more than advertising. Amazon guided Q3 2025 net sales to $174.0 billion to $179.5 billion, or 10% to 13% growth, and operating income to $15.5 billion to $20.5 billion. CNBC reported that the operating-income guide compared with a roughly $19.4 billion Street estimate and that shares fell about 7% to 8% after the print. [1][3]

That market reaction is context, not a correction to the advertising number. The ad business beat the StreetAccount estimate cited by CNBC. AWS growth and profit guidance carried more of the investor disappointment. For advertisers using this quarter as a benchmark, the ad line itself was not weak; the attribution story around it is the part that needs discipline.

Basis checks for anyone updating the spreadsheet

• Use $15,694 million as the reported Q2 2025 advertising services revenue. Rounded coverage may say $15.69 billion or $15.7 billion, but the spreadsheet line is $15,694 million. [1][3]
• Keep both growth bases: +23% year over year as reported and +22% excluding foreign exchange. A headline that says 22% is usually using the ex-FX basis, not contradicting Amazon’s reported-growth number. [1]
• Treat 9.36% ad share as Marketplace Pulse analysis, not an Amazon-disclosed metric. It is useful for weight inside the company, not a replacement for the company’s revenue table. [2]
• Use the CFO-attributed $31.4 billion capex figure when discussing the Q2 AI spending signal. Do not convert it into an AI advertising revenue-impact estimate. [5][6]
• Do not let Q2 2026 search results contaminate this page. This record is for the quarter reported July 31, 2025; later Amazon AI ad products and July Prime Day 2025 performance belong outside this Q2 2025 revenue record unless explicitly labeled as forward context.

What Q2 2025 can support

Q2 2025 supports a strong Amazon Ads revenue record: $15,694 million, +23% reported, +22% ex-FX, an acceleration from the prior quarter and a larger share of Amazon’s total revenue mix. It also supports a practical list of disclosed accelerators: a large ad-supported audience, full-funnel ad offerings, CTV distribution deals with Roku and Disney, and a marketplace with more ad monetization.

It does not support a measured AI-lift claim. The only verifiable AI-adjacent signal in the quarter is spending, not disclosed advertising revenue impact.
