UPS Stopped Carrying 2 Million Amazon Packages a Day. Amazon Still Has to Move Them.

UPS said it eliminated about 2 million pieces per day of lower-quality Amazon volume, removing roughly $4.5B of related expenses. In Q2, UPS’s U.S. domestic revenue rose 6% YoY, revenue per piece grew 9.3%, and the non-GAAP operating margin expanded to 8% (+100 bps), with UPS raising its full-year revenue outlook to about $91.2B. The flip side for Amazon: its delivery arm handled ~6.7B U.S. parcels in 2025 and Amazon’s worldwide shipping costs jumped to $27.9B in Q2 (+19% YoY) versus online-store sales up 15%, implying delivery costs are outpacing sales growth.

Analysis

UPS’s real catalyst is not the volume loss itself but the removal of structurally bad mix. When a carrier exits low-density residential parcels, the network can reprice around higher-yield business and B2B freight, which is why margin can expand even as headline volume falls; that also supports dividend durability and buyback capacity over the next 2-4 quarters.

For Amazon, the logistics spend is increasingly a deliberate operating expense, but the second-order issue is fixed-cost absorption. Owning more of the last mile improves customer control, yet it also increases depreciation, labor, and peak-season execution risk; if shipping outgrows retail revenue for another quarter or two, that becomes a quieter but persistent drag on e-commerce operating income.

The competitive spillover is more nuanced than a simple carrier-vs-platform trade. FedEx and USPS can absorb some displaced parcels, but the bigger shift is pricing discipline: if UPS no longer needs to chase marginal Amazon volume, the entire parcel market loses a low-margin reference point, which is constructive for carrier pricing power into peak season. The contrarian risk is that the market overreads Amazon’s self-delivery build as an immediate moat win; the payoff is likely years away, while the cost is immediate. The thesis breaks if UPS gives back margin in the next earnings cycle or if Amazon’s shipping cost growth decelerates materially versus sales growth.

Key Decisions for Investors

• Long UPS on a 1-3 month horizon; add on pullbacks if the market is still anchored to lost volume rather than margin mix. Risk/reward is favorable as long as domestic margin holds near current levels and revenue-per-piece remains elevated.
• Relative-value pair: long UPS / short AMZN modestly sized into the next earnings cycle. This works only if Amazon shipping costs continue rising faster than online sales; cover the short if Amazon shows meaningful logistics cost leverage or better-than-expected retail margin.
• Buy FDX only on sector weakness, not strength, as a secondary beneficiary of carrier rationalization. The setup is weaker than UPS, but a re-rating is possible if FedEx shows it can capture spillover parcels without sacrificing yield.
• Set an alert on AMZN shipping cost growth versus online-store sales growth. If shipping costs stay >3-4 pts faster for another quarter, treat it as a structural retail margin headwind; if it compresses sharply, abandon any bearish Amazon relative trade.
