Amazon Ad Spend Defies Economic Headwinds as Prime Big Deal Days Spark Up-Funnel Investment

By Global Business and Media Desk
Published: October 2026

Despite a cocktail of rising fuel prices, lingering inflationary pressures, and declining consumer confidence across the United States, global marketers are enthusiastically opening their wallets for Amazon’s latest retail extravaganza. As the e-commerce titan rolls out its "Prime Big Deal Days" fall shopping event on October 6–7, the accompanying surge in media investments underscores a profound shift in how brands perceive and utilize Amazon’s vast digital ecosystem.

Rather than pulling back in the face of macro-economic uncertainty, brands are dramatically increasing their budgetary commitments. According to interviews with prominent media buyers and agency executives, client ad spending on Amazon Ads prior to this fall’s event has jumped between 15% and 40% compared to the same period last year. Industry forecasts indicate that this momentum will carry through the holiday season, with total spending projected to grow by as much as a third by the end of 2026.

This resilience comes on the heels of a massive second quarter for Amazon’s advertising division. Bolstered by robust platform engagement, Amazon reported that its ad revenue surged to $19.8 billion in Q2 alone—representing an impressive 26% year-on-year increase. Even with ongoing regulatory scrutiny, such as the Federal Trade Commission’s (FTC) ongoing investigation into Amazon’s ad auction practices, brand demand remains steadfastly insulated. For modern marketers, performance continues to outweigh political and legal noise.

Main Facts: The Anatomy of Amazon’s Fall Ad Surge

The landscape of retail media is undergoing a structural evolution. No longer viewed strictly as a "pay-to-play" marketplace for lower-funnel search results, Amazon has successfully positioned itself as an indispensable top- and mid-funnel media destination.

• Significant Growth Trajectory: Media buyers report that pre-Prime Day client spending has risen by 15% to 40% year-over-year.
• Endemic vs. Non-Endemic Split: Growth is driven by both "endemic" brands (companies that sell products directly through Amazon) and "non-endemic" brands (companies that do not sell on Amazon, but utilize its proprietary audiences and first-party retail data).
• The Rise of the Amazon DSP: Marketers are strategically shifting budgets upward into the Amazon Demand-Side Platform (DSP), heavily prioritizing Connected TV (CTV), online video (OLV), and streaming audio over traditional sponsored product listings.
• Regulatory Immunity: Agency executives confirm that the FTC’s antitrust and ad auction investigations have had virtually zero impact on client spending decisions.

Chronology: From Summer Sales to the Holiday Peak

To understand how brands approach the October Prime Big Deal Days, one must look at the calendar shifts that have defined 2026’s retail strategy.

Q2 2026: Earnings and Momentum

In July, Amazon released its second-quarter financial results, revealing a staggering $19.8 billion in advertising revenue—a 26% year-on-year climb. This earnings report set an aggressive tone for the rest of the year, signaling to Wall Street and Madison Avenue alike that Amazon’s ad inventory was scaling rapidly.

Summer 2026: The Shorter Prime Day Event

Earlier in the summer, Amazon hosted its primary global Prime Day. However, the event was notably compressed into a two-day window, a stark contrast to the four-day promotional marathon seen in 2025. According to research from agency PMG, July’s event accounted for roughly 3% of annual U.S. Amazon sales, translating to about 57% of the total revenue generated by the longer event the previous year. This compression forced brands to re-evaluate their calendars, recognizing that the shortened window limited lower-funnel sales potential.

Early October 2026: The Prime Big Deal Days Catalyst

Landing just weeks ahead of the traditional Black Friday and Cyber Monday retail peak, the October Prime Big Deal Days event functions less as a standalone revenue driver and more as a strategic lever. For many brands, the October event serves as an inventory management tool—a way to clear out fulfillment centers before the critical year-end holidays. Consequently, marketers have modified their tactics, distributing their budgets across the pre-event run-up rather than concentrating spend solely on the 48 hours of the sale itself.

Supporting Data: What the Numbers Tell Us

The data compiled from top-tier media agencies reveals a nuanced picture of shifting digital marketing allocations:

• Darren D’Altorio (Wpromote): Reports a 30% year-on-year growth for endemic brands and a 40% year-on-year growth for non-endemic brands on Amazon Ads.
• Katie Davis (Power Digital): Notes that while ad spend is still climbing, the rate has normalized to 15-20% growth—down from the 40-50% leaps seen in past years—due to buyer economic headwinds and perpetual discounting.
• Joe O’Connor (Tinuiti): Highlights that Tinuiti-managed clients are increasing their year-on-year Amazon spend by approximately 15%, while ad spend managed through Amazon’s DSP has surged by 25%-30% compared to 2025.
• PMG Metrics: Estimates that the average discount depth fell from 28% in 2024 to 24% last year as brands grappled with tariff adjustments and supply chain cost pressures. Further moderation of discounts below 20% is expected through the remainder of 2026.
• MiQ Research: Points out that 76% of consumers habitually watch television or streaming content while simultaneously using a second screen for shopping activities—a behavioral habit that directly fuels Amazon’s cross-channel ad efficacy.

Official Responses and Industry Perspectives

Industry leaders across performance marketing and media buying agencies have offered deep insights into why Amazon continues to command outsized budgets despite economic headwinds.

The Shift to Brand Building and Upper-Funnel DSP

According to Katie Davis, director of retail marketing at Power Digital, much of the budgetary growth is migrating away from traditional sponsored product ads and heading straight into the Amazon DSP.

"Amazon DSP continues to be viewed more as a brand building lever for media dollars than a retail checkout driver," said Davis. "Amazon’s positioning and competitive advantage in the DSP space are growing more and more prominent as we head toward 2027."

This sentiment is echoed by Ashley Hutchings, vice president and head of digital and partnerships at KSM Media, who noted a broader industry movement toward proprietary, high-quality inventory. "More spend is moving into Amazon-owned inventory, including Twitch, Prime Video, and sports. We’re also seeing greater DSP diversification as marketers move toward platforms with proprietary, high-quality inventory," Hutchings observed.

Prime Video as a "Gateway" for Non-Endemic Brands

For companies that do not physically sell goods on Amazon, Prime Video and streaming audio have become the ultimate entry points.

"We see Prime Video really driving growth with a lot of our non-endemic clients who are starting to test Amazon," explained Joe O’Connor, senior director of innovation and growth for Amazon at Tinuiti. "At the end of the day, what our clients care about is performance, and they continue to invest in Amazon because it’s performing."

Hillary Bram, vice president of performance buying at Exverus by Brainlabs, emphasizes that full-funnel strategies are proving mandatory across all major retail platforms. "We’re seeing that trend across all retailers—that diversity of placement, diversity of tactic, is lifting the bottom line."

CFO Defensibility and the Value of Targeting Data

For corporate marketing teams, securing budget approval in an uncertain economic climate requires hard proof of return on investment. Darren D’Altorio of Wpromote points out that Amazon’s granular targeting data and its unique proximity to the point of purchase make it an easy sell to financial executives.

"It is becoming increasingly more defensible to the CFO why we should be investing there," D’Altorio stated, emphasizing that Amazon has cemented itself as a core component of modern commercial strategy.

Implications: The Future of Retail Media and Discount Fatigue

As the retail industry looks past the October Prime Big Deal Days and stares down the barrel of the 2026 holiday shopping season, several critical implications emerge for brands, agencies, and Amazon itself.

1. The Death of the Endless Discount?

For years, promotional events like Prime Day and Black Friday trained consumers to expect massive markdowns. However, rising supply chain costs, tariffs, and margin compression have forced brands to rethink this paradigm. With average discount depths shrinking from 28% to 24%—and projected to drop below 20%—marketers are increasingly questioning the long-term profitability of aggressive price-cutting.

If brands successfully scale back discounting without sacrificing sales volume, it could permanently alter the economics of retail holiday events. However, if consumer resistance hardens in the face of dampened confidence, brands may find themselves trapped between the necessity of promotions and the preservation of profit margins.

2. Amazon’s Hegemony in the DSP Market

By successfully integrating Prime Video, live sports (such as Thursday Night Football), Twitch, and Fire TV into its advertising ecosystem, Amazon has evolved far beyond an e-commerce catalog. It is now a fully realized entertainment and media titan. The rapid migration of ad dollars into Amazon DSP indicates that marketers view the platform’s audience data as superior to traditional linear television and open-web programmatic channels. This competitive moat makes Amazon virtually peerless in the current commerce media landscape.

3. Regulatory Resilience

Despite ongoing scrutiny from antitrust regulators and the FTC’s active investigation into ad auction mechanisms, enterprise brands have displayed a remarkable degree of nonchalance. As noted by Markacy co-founder Tucker Matheson, regulatory actions have had "no impact" on client demand. So long as Amazon’s ad inventory consistently delivers measurable, bottom-line returns, corporate boards and chief financial officers will continue to greenlight massive budgetary allocations.

Looking Ahead to 2027

As brands finalize their budgets for the upcoming year, the overarching consensus is clear: Amazon is no longer an experimental line item or a seasonal tactical afterthought. It is a foundational pillar of modern media planning. Whether marketers can successfully decouple volume growth from heavy discounting remains the central question for the quarters ahead. For now, however, Amazon’s ad machine marches forward, entirely unfazed by the economic clouds overhead.
