Amazon's Shipping Costs Jump 11% in Q3 as Fuel and Linehaul Bite

Amazon's worldwide shipping costs climbed 11% year over year to $28.3 billion in the third quarter, as fuel inflation and higher linehaul rates squeezed the e-commerce giant's fulfillment network even as it posted record operating profitability.

The company reported the figures Thursday after market close. Total revenue reached $201.9 billion, up 12% from $180.2 billion a year earlier, while operating income surged 61% to $28.1 billion from $17.4 billion. The operating margin hit 13.9% — Amazon's highest ever.

Both headline numbers still missed Wall Street. Revenue came in below the $202.3 billion analysts expected, and earnings per share of $1.89 fell short of the $1.96 consensus.

What did management say about freight costs?

Chief Financial Officer Brian Olszewski was direct about the pressure. "In our fulfillment network, the team navigated higher transportation costs from fuel inflation and higher line haul rates," he said on the earnings call.

Despite that, Amazon lowered its overall cost to serve during the quarter through better inventory placement, shorter shipping distances and package consolidation, Olszewski said.

The numbers back him up. Shipping costs grew 11% against 12% growth in units shipped. Strip out fuel and linehaul inflation, and shipping costs rose just 8% — roughly 4 percentage points slower than unit growth.

CEO Andy Jassy told analysts the cost discipline is structural. "We're on track to reduce cost to serve per unit for the fourth consecutive year," he said, crediting investments in same-day fulfillment facilities and ultra-fast delivery services with attracting customers while cutting fulfillment expenditures.

Fulfillment expenses overall rose 8.4% to $30 billion from $27.7 billion.

How did each segment perform?

The North America segment, covering U.S. and Canadian retail, generated $112.9 billion in revenue, up 6% year over year. Segment operating income jumped roughly 81% to $8.7 billion from $4.8 billion, putting the North America operating margin at 7.7%.

International revenue increased 5% to $43.1 billion, with operating income climbing to $1.6 billion from $1.2 billion.

One timing wrinkle skewed comparisons: Prime Day fell in the second quarter of 2026 for most major markets, versus the third quarter in 2025. Excluding that shift, Amazon estimated Q3 revenue growth would have been about 4 percentage points higher.

What role is automation playing?

A big one. Jassy told analysts Amazon now operates more than 1 million robots across its fulfillment network. Robotics, he said, has driven improved productivity, reduced operating costs and record-low safety incident levels across fulfillment operations.

Amazon doubled its fleet of robotic arms — including Cardinal and Sparrow systems — during 2026, according to Olszewski. The company is also developing robotics foundation models designed to help machines handle increasingly complex physical tasks.

Speed kept improving too. Amazon logged its fastest third-quarter delivery speeds ever for Prime members, moving more than 1.5 billion items on the same day or overnight during the quarter ended Sept. 30. Worldwide paid-unit growth ran at 12%, up 1 point year over year.

Will Q4 freight pressure worsen?

Yes, by management's own account. During the call's question-and-answer session, Jassy said transportation cost pressures will continue into the fourth quarter, and that the impact from fuel and linehaul inflation will be somewhat higher than in Q3.

Amazon implemented a fuel surcharge earlier this year for sellers using Fulfillment by Amazon, recovering some of the added expense. But Jassy conceded the surcharge does not fully offset the increases, leaving Amazon exposed on both inbound retail shipments and outbound deliveries.

The guidance reflects that drag. Amazon expects fourth-quarter net sales of $240 billion to $247 billion, a 12% to 16% increase year over year, with operating income of $28.5 billion to $33.5 billion against $25 billion in the prior-year period.

AWS remains the profit engine alongside retail, with cloud revenue up 39.3% to $46 billion. Third-party seller services revenue rose 9.4% to $46.5 billion, while online store revenue inched up 1.6% to $68.5 billion.

Net income actually fell 2.4% to $20.7 billion, with diluted EPS down 3.1% to $1.89 — a reminder that freight inflation and one-off timing effects still show up in the bottom line even as operating leverage improves.

Heading into the fourth quarter, shippers and carriers watching Amazon's network should expect the freight-cost squeeze to tighten before robotics and inventory placement catch up.
