Amazon CEO Andy Jassy yesterday published his annual letter to shareholders, covering the company's full-year 2025 performance and strategic outlook. The letter runs roughly 10 pages. Of those pages, a single sentence addresses one of the company's fastest-growing and most profitable business segments: advertising.

"Our Advertising offerings continue to grow and deliver strong returns for brands," according to the shareholder letter published April 9, 2026.

That is the complete passage. Not a paragraph - a sentence. Meanwhile, the word "AWS" appears 46 times across the document. Even Prime Air, Amazon's drone delivery programme, receives three mentions.

The disproportion has not gone unnoticed inside the industry. Alan Lewis, a former Amazon product leader who worked on Clean Rooms and data platforms, posted about the omission on LinkedIn within hours of the letter's publication. "That's it," Lewis wrote. "That's the entire space allocated to one of if not the most important growth engine for the company." Lewis, identifying himself as annoyed on behalf of former colleagues in the Ads division, asked directly: "Which 6 pages do you want us to read, Andy?"

The reaction on LinkedIn was immediate. Several industry figures offered competing explanations for the gap - some structural, some more pointed.

The numbers behind the one sentence

To understand the scale of what received a single sentence, the financial figures are worth examining in full. According to the Q4 2025 earnings results reported February 6, 2026, Amazon's advertising services segment generated $68.6 billion in full-year 2025 revenue. In the fourth quarter alone, advertising revenue reached $21.3 billion, growing 23 percent year-over-year. That was the segment's strongest quarterly performance of the year. CFO Brian Olsavsky stated during the earnings call that advertising contributed more than $12 billion of incremental revenue to Amazon during 2025.

The segment's quarterly trajectory through 2025 tells its own story. Revenue reached $13.9 billion in Q1 2025 with 19 percent growth, climbed to $15.7 billion in Q2 with 22 percent growth, rose to $17.7 billion in Q3 with 22 percent growth, and reached $21.3 billion in Q4 with 23 percent growth. The acceleration across four consecutive quarters represents sustained demand that most advertising businesses would frame as a headline achievement.

The Trade Desk CEO Jeff Green noted during a November 7, 2025 earnings call that Amazon would likely generate approximately $70 billion in advertising for the year. Green estimated roughly 90 percent of that revenue sits in Sponsored Listings - formats competing directly with Google Search and emerging AI search platforms. Amazon is now the third-largest digital advertising platform globally, behind only Meta and Alphabet.

For comparison: Amazon's total revenue in 2025 grew 12 percent year-over-year from $638 billion to $717 billion, according to the shareholder letter. AWS revenue grew 20 percent, from $108 billion to $129 billion. The advertising segment, at $68.6 billion, represents roughly ten percent of total company revenue - and is growing faster than the North America retail segment, which increased 10 percent year-over-year.

Competing explanations from industry insiders

The LinkedIn discussion surfaces genuinely different interpretations of the omission, not a simple consensus.

Carson Henry, CEO of [cognition], offered what he framed as an audience-based explanation. According to Henry, "Ads isn't sexy. Retail investors don't invest in advertising companies. He's playing to the audience." Henry added that this did not necessarily mean Jassy does not understand the value of advertising - only that retail shareholders may not.

Jim Caralis, a product and engineering leader who previously worked at global companies, pushed back on any implicit suggestion that advertising is a low-complexity business. According to Caralis, computing an accurate probability and relevance measure for a rare event like a click or conversion to drive value to an advertiser is "a uniquely hard challenge," along with five to seven other difficult technical problems. Neal Richter, Vice President of Advertising Science and Engineering, echoed this view in a reply to Caralis, noting the technical sophistication involved.

Bismit Boruah, a digital advertising GTM and revenue leader, offered the simplest counterargument: "Or Amz Ads is doing so awesome that we don't need to speak at length about it."

Sunny Youn, described as an AI futurist at Meta and former Amazon employee, offered the most direct assessment: "No, Jassy doesn't care about Ads. The focus is AI (chips) and AWS."

One anonymous account, identified as "My DTC Guy" with 531 followers, put it more bluntly: "Amazon makes billions on ads and still treats it like a side hustle."

Lewis, in a follow-up reply to Henry, kept his own position open. "IDK," he wrote. "Jury's out on whether or not he understands the value."

What the letter actually says - and doesn't say

The shareholder letter does discuss Amazon's broader financial picture at length, and advertising does appear obliquely in the final pages. According to the letter, "Our Advertising offerings continue to grow and deliver strong returns for brands, while newer businesses like Prime Video, Pharmacy, and Grocery are providing unique customer experiences, growing robustly, and improving their economics."

That is the sum of advertising's named appearance. The letter dedicates far more space to AWS's AI infrastructurebuildout, including specific figures: AWS added 3.9 gigawatts of new power capacity in 2025, expects to double total power capacity by the end of 2027, and reported 24 percent year-over-year growth in Q4 2025 with a $142 billion revenue run rate, according to the letter.

The letter also discusses Amazon's custom silicon programme in substantial detail. According to Jassy, the annual revenue run rate for Amazon's chips business - covering Graviton, Trainium, and Nitro - is now over $20 billion and growing at triple-digit percentages year-over-year. The letter notes that if the chips business operated as a standalone entity selling to third parties, the annual run rate would be approximately $50 billion. Trainium3, which began shipping at the start of 2026, is 30 to 40 percent more price-performant than Trainium2 and is "nearly fully-subscribed," according to the letter.

Bedrock, Amazon's primary inference service, processes so many tokens that the team built an entirely new inference engine. According to the letter, a six-person engineering group using Amazon's Kiro agentic coding service delivered the new engine - called "Mantle" - in 76 days. Bedrock "nearly doubled month-over-month" in March 2026 and "processed more tokens in Q1 2026 than all of the tokens processed in the prior years combined," according to the letter.

Against that level of specificity, the single advertising sentence stands out more sharply.

The advertising infrastructure that didn't make the letter

The structural omission is notable because 2025 was, by any operational measure, a year of significant activity for Amazon Ads specifically - well beyond the revenue line.

In November 2025, Amazon announced a unified Campaign Manager platform that collapsed the Amazon DSP and Ads Console into a single buying tool. The consolidation, announced at Amazon's annual unBoxed conference on November 11, also introduced Ads Agent - an AI system that processes natural language instructions to execute campaign management tasks - and expanded Creative Agent capabilities to support Streaming TV and Sponsored TV formats.

That same month, Amazon launched Sponsored Products video, a new format enabling advertisers to upload between one and five product feature videos per product. Early testing data showed a 9 percent click-through rate increase for campaigns using the format, with rates jumping 8 times higher for the 20 percent of shoppers who watched for longer than five seconds.

In October 2025, Amazon introduced reserve share of voice for branded search, allowing advertisers to secure top-of-search Sponsored Brands placements for branded keywords at a fixed, upfront price through API access - a structural departure from purely auction-based dynamics.

Amazon DSP also expanded significantly during 2025. The platform integrated Netflix's ad-supported tier in Q4 2025, providing advertisers with direct access to premium streaming content across 11 countries. Spotify's global audio and video inventory became available through Amazon DSP in October, delivering programmatic access to 696 million monthly ad-supported listeners across nine markets. Amazon DSP added in-market audiences across 32 countries in November.

Prime Video's advertising scale also grew. According to data published around the German market, Prime Video maintains an average monthly ad-supported reach exceeding 17 million customers in Germany alone, with 95 percent of those viewers making Amazon purchases within the previous three months.

On the AI shopping side, Rufus - Amazon's AI shopping assistant - reached more than 300 million users throughout 2025 and generated nearly $12 billion in incremental annualized sales. The assistant moved out of open beta for its advertising integrations on March 25, 2026, when Sponsored Products prompts and Sponsored Brands prompts transitioned to general availability with CPC billing - a direct monetisation of AI-mediated shopping conversations.

None of this appeared in the shareholder letter.

Why this matters for the marketing community

The structural question Lewis raises goes beyond shareholder communication. If the senior leadership of a platform does not publicly frame advertising as a strategic priority - at the level of specificity given to AWS, chips, and logistics - what signals does that send to teams building advertising products, to agencies planning budget allocations, and to brands evaluating whether Amazon Ads deserves parity with Meta and Google in their planning cycles?

Amazon's advertising business now faces a genuinely complex set of pressures that a single sentence does not capture. Third-party AI shopping agents - capable of browsing, comparing, and purchasing on behalf of users without ever viewing a sponsored listing - represent a structural challenge to a business model built around human attention. Amazon has responded by filing suit against Perplexity AI, while simultaneously deploying its own AI shopping agents across its platform and onto third-party retailer websites.

The April 15, 2026 billing change, where advertising costs for certain sellers will automatically deduct from retail proceeds rather than billing separately to credit cards, generated significant industry discussion in the first week of April. The change affects cash flow management for sellers who had used separate billing cycles as a working capital buffer. Amazon clarified that Pay by Invoice remains available as an alternative and that credit cards continue as a backup option, but the initial seller reaction treated the notification as a broader credit card ban.

The broader picture is of an advertising business large enough to sit alongside the world's largest digital ad platforms, operating without the same level of visible CEO attention those businesses receive from their own leadership.

Timeline

Summary

Who: Amazon CEO Andy Jassy, writing the 2025 annual shareholder letter to investors. Responses came from Alan Lewis (ex-Amazon product leader), Jim Caralis (product and engineering leader), Carson Henry (CEO of [cognition]), Neal Richter (VP Advertising Science and Engineering), Bismit Boruah (digital ads GTM and revenue leader), and Sunny Youn (AI futurist at Meta and former Amazon employee).

What: The 2025 Amazon shareholder letter, published April 9, 2026, devoted a single sentence to Amazon's advertising business despite the segment generating $68.6 billion in full-year revenue and growing 23 percent year-over-year in Q4 2025. AWS was mentioned 46 times. The disproportion prompted immediate industry discussion on LinkedIn about whether advertising receives appropriate strategic recognition at the CEO level.

When: The letter was published April 9, 2026. LinkedIn discussion began within hours of publication. The advertising revenue figures cover full-year 2025 and Q4 2025, reported February 6, 2026.

Where: The shareholder letter was published on Amazon News. Industry reaction appeared on LinkedIn. The advertising revenue originates from Amazon's global platform spanning its retail marketplace, Prime Video, Twitch, Fire TV, and live sports.

Why: The omission matters because advertising is Amazon's third-largest segment by revenue, the company's fastest-growing major division outside of AWS, and a business with structural challenges - including third-party AI shopping agents and billing changes - that were not addressed in the letter. For marketing professionals, the framing signals how advertising sits within Amazon's stated strategic hierarchy relative to cloud infrastructure and AI.
