Amazon Cuts Ties with USPS Amid Contract Negotiation Fallout
Amazon said contract renewal negotiations with the U.S. Postal Service collapsed in December after the Postal Service "abruptly walked away at the eleventh hour," according to a company blog post. Reports say Amazon plans to cut the number of packages it sends via USPS by at least two-thirds when the contract expires at the end of September. Amazon said it had been negotiating for more than a year and has submitted a bid in the Postal Service’s new auction process, hoping to continue a reduced partnership. The USPS in December launched a last-mile bid solicitation platform and Postmaster General David Steiner has warned the carrier could run out of cash within a year without Congressional help. Amazon has been expanding its own logistics network, including a $4 billion commitment to grow rural delivery by 2026.
A major change in the Amazon–USPS relationship and a potential two-thirds reduction in USPS volumes could materially affect last-mile logistics, USPS finances, and retailers' delivery networks; relevant to commerce, fulfillment costs, and supply-chain planning.

UPS investing $2 billion in air hubs, healthcare logistics amid Amazon pullback
UPS announced a $2 billion investment on August 24, 2026, to expand air-cargo hubs and healthcare logistics across Europe, Asia-Pacific and the Americas. The program includes new hubs in the Philippines and Hong Kong, an expanded Incheon facility, and 27 temperature-controlled facilities. This move supports UPS's strategic shift away from low-margin Amazon volume toward higher-value healthcare and supply-chain business.
Amazon Tightens Shipping Requirements for Marketplace Sellers
Amazon announced a step‑by‑step tightening of shipping and handling-time requirements for marketplace sellers who fulfill orders themselves (not using Fulfillment by Amazon). Sellers must ensure their listed processing/handling times closely match actual shipping speeds; Amazon may override seller settings and recommends enabling its “Automated Handling Time” feature. Participants in Seller Fulfilled Prime (SFP) will face stricter nationwide one‑to‑two day delivery targets. Amazon will also roll out a tool to calculate delivery commitments at postal-code level. Non-compliance risks losing the Prime badge, reduced visibility and Buy Box share. Amazon cites internal data showing over 87% of self‑fulfilled orders are processed within one day and that a one‑day faster delivery promise can increase sales by roughly 5%. Smaller sellers warn the measures could force greater logistics costs or push them toward Amazon’s fulfillment service.
Amazon Tightens Margins and Liquidity for Sellers
ADZINE reports that Amazon is increasing financial pressure on its third‑party sellers through several platform changes. A planned switch would have advertisers' paid media costs automatically deducted from sales proceeds before charging other payment methods, reducing sellers' liquidity; after market pushback Amazon postponed this change to August 1, 2026 and announced supporting ad-credit programs. The change coincides with other measures—delayed payouts under a "Delivery Date + 7" model and additional logistics fees—creating a cumulative margin squeeze. Some sellers briefly paused advertising in April and are evaluating diversification (own shops, alternative channels) to reduce dependence on Amazon. The piece frames these moves as part of a wider platform-economy dynamic where retail marketplaces bundle commerce, logistics and advertising, increasing sellers' operational exposure to platform policy shifts.
