Big Tech AI Capex Strains Core Revenue | Seller Impact Analysis 2025
- Amazon capex reached 220 billion this year, pushing marketplace ad and fee pressure onto sellers
Overview
Meta, Alphabet, Amazon and Microsoft are pouring trillions into AI infrastructure while their legacy businesses weaken, and this pressure could reshape Amazon fee structures and advertising pricing for cross-border sellers. According to CNBC reporting on the latest earnings cycle, Meta, Alphabet and Amazon posted negative free cash flow, while Microsoft stayed the only hyperscaler with positive free cash flow at 18.63 billion after a 27 percent decline. Amazon's outflows swelled to 42.4 billion, and its online sales grew just 2 percent year over year, down from 10 percent a year earlier.
The news reports that Amazon expects capital expenditures of 220 billion this year, with FactSet data projecting more than 280 billion next year. This indicates that platform operators are funding AI through core commerce and advertising cash flows, which typically pushes marketplaces toward higher monetization. Industry data shows that when marketplace ad revenue slows, platforms often respond by expanding sponsored product inventory and adjusting referral or fulfillment fees. Sellers in competitive categories such as electronics and home goods typically see advertising cost-per-click rise 10-20 percent during such periods, which compresses margins for small sellers running Amazon PPC campaigns.
The news reports that Alphabet's core search business posted a third straight quarter of slowing growth, while YouTube advertising revenue also came in light. Forrester analyst Tracy Woo warned that AI chatbots and agents could displace the largest revenue generators, which may push ad budgets toward platforms with clearer conversion data. Specifically for sellers, this signals a shift in where shoppers begin product discovery. Looking at platform data, AI-driven shopping assistants could route buyers directly to marketplace listings, making structured product data, complete attributes and high-quality images more valuable than traditional keyword bidding.
The context includes a balanced view. Investor Christopher Ballard of Check Capital Management argued that Alphabet's negative free cash flow of roughly 9 billion is small relative to operating income topping 40 billion for the quarter, while Amazon CEO Andy Jassy stated the opportunity does not unfold over 25 years. Meta's capex is projected to pass 210 billion in 2027, and returns depend on whether AI creates new revenue streams fast enough to match spending.
Questions 4
Is Microsoft a safer platform partner than Meta, Alphabet or Amazon right now?
Microsoft was the only hyperscaler with positive free cash flow, at 18.63 billion after a 27 percent decline, according to the news reports. Microsoft said it will turn to the bond market to fund AI spending, which shifts financing risk rather than eliminating it. For sellers, financial stability matters less than platform reach and policy predictability. Diversifying across Amazon, Shopify and Walmart marketplaces remains the practical hedge. Review platform payout schedules and reserves quarterly to protect working capital.
Will Amazon change seller fees because of its AI infrastructure spending?
The article does not specify any seller policy or fee changes. It does signal that platform operators such as Amazon may prioritize cost control and monetization, which could influence fee structures and advertising pricing. Amazon expects capital expenditures of 220 billion this year, and FactSet projects more than 280 billion next year. Sellers should review Amazon fee schedules in Seller Central each quarter and model fulfillment cost scenarios with a 5-10 percent increase buffer. Avoid assuming fee stability over the next 6-12 months.
