The Amazon-USPS 2026 Deal: 1 Billion Packages, $6B in Revenue, and What it Means for Everyone Else.
On April 6, 2026, Amazon and the U.S. Postal Service ended a four-month standoff with a deal that preserves roughly 80% of Amazon's existing USPS volume — over a billion packages a year and an estimated $6 billion in annual revenue to a postal service that just posted a $9 billion loss. For DTC and 3PL shippers, the deal is less a conclusion than a starting gun.

TL;DR
Reuters first reported on April 6, 2026 that Amazon and USPS reached a tentative deal preserving roughly 80% of Amazon's existing USPS volume — more than 1 billion packages annually, ~$6B in revenue.
The deal ended a dispute that began in December 2025, when Postmaster General David Steiner moved to open last-mile capacity to competitive bidding. Amazon publicly threatened to pull two-thirds or more of its USPS volume.
USPS posted a $9.0 billion net loss in FY2025 on $80.5B revenue. Losing Amazon would have torn a hole that no Ground Advantage growth could plausibly fill in 2026 or 2027.
USPS filed an 8% temporary surcharge on Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select effective April 26, 2026 — three weeks after the Amazon deal was announced.
Amazon kept ~80% of USPS volume but is still building. Its $4B rural delivery push (200 stations, 13,000 ZIPs) and an Amazon Air fleet of ~95–100 freighters point to a structural decoupling, just on a 24–36 month timeline rather than 12.
For non-Amazon shippers: lock 2026 USPS rates in writing now, model a 10–15% Ground Advantage rate scenario, and aggressively benchmark regional carriers and FedEx Ground Economy / UPS Ground Saver before peak.
01What was actually announced
The terms of the April 6, 2026 deal
Reuters broke the news on the morning of April 6, 2026: Amazon and the U.S. Postal Service had reached a new agreement on package delivery, ending months of public brinksmanship.[1] The same day, Bloomberg reported the agreement preserves roughly 80% of USPS's existing Amazon volume, which Postmaster General David Steiner had previously disclosed at about 1.7 billion packages a year — implying USPS will continue delivering on the order of 1.3–1.4 billion Amazon parcels annually under the new deal.[4]
Amazon's spokesperson Terrence Clark said in a statement that the company was "pleased to have reached a new agreement with USPS that furthers our longstanding partnership and will let us continue supporting our customers and communities together."[3] USPS declined immediate comment. Financial terms were not disclosed; sources told Reuters and Bloomberg that Amazon represents approximately $6 billion in annual revenue for USPS — a meaningful slice of the agency's $80.5 billion in FY2025 operating revenue.[4][8]
We're pleased to have reached a new agreement with USPS that furthers our longstanding partnership and will let us continue supporting our customers and communities together.
The deal is described as tentative and must still be approved by the Postal Regulatory Commission (PRC).[3][5] Per the PRC's Negotiated Service Agreement framework, large-shipper contracts are required to demonstrate they will not lose money for USPS and will not unduly burden other rate categories. PRC review typically runs 30–45 days; the contract covering the volume in dispute was set to expire in October 2026, putting real pressure on both sides to land a deal in spring.[18]
How big a slice of USPS volume is Amazon, really?
ShipMatrix's 2024 U.S. Domestic Parcel Market Report pegged USPS at 7.2 billion packages for calendar 2024 and Amazon Logistics at 6.1 billion.[12][13] Pitney Bowes's independent Parcel Shipping Index puts USPS at 6.9 billion and Amazon at 6.3 billion for the same year.[14] Both data sets agree on direction: roughly 15–20% of USPS's package volume is Amazon-injected. PYMNTS estimated the share at approximately 15% in coverage of the deal.[3] A two-thirds cut, which Amazon publicly threatened in March, would have stripped out 1.0–1.1 billion parcels — roughly the entire annualized growth of USPS Ground Advantage since launch.[5][10]

02Why USPS could not afford to lose Amazon
$9 billion in losses and a $15 billion debt ceiling
On November 14, 2025, USPS reported a $9.0 billion net loss for fiscal year 2025 on operating revenue of $80.5 billion — its eighteenth consecutive year of losses, narrowing from a $9.5 billion loss in FY2024.[8]The agency's "controllable loss," which excludes items like Postal Service Retiree Health Benefits Fund actuarial adjustments, widened to $2.7 billion from $1.8 billion the prior year.[8][9]
Shipping and Packages revenue was $32.58 billion in FY2025 (up 1% year over year), with volume of 6.84 billion pieces, down 5.7%.[8] The bright spot was Ground Advantage: revenue of $16.2 billion (+20.7%) on volume of 2.93 billion pieces (+21.0%).[8] Even with that double-digit Ground Advantage growth, Mailing Services revenue continued its secular slide as First-Class Mail volume erodes.
USPS has now reached its statutory $15 billion borrowing limit with the U.S. Treasury and cannot finance additional deficits with new debt without Congressional action.[9] In Congressional testimony and in the FY2025 results call, Postmaster General David Steiner — appointed May 9, 2025 after the resignation of Louis DeJoy[17] — has warned that without legislative action and new revenue sources, the agency could exhaust its cash reserves within months.[9]
Roughly $118 billion in net losses across nearly two decades.
Against that backdrop, Amazon's ~$6 billion in annual revenue — about 7.5% of total USPS operating revenue and almost a fifth of all Shipping and Packages revenue — is not a contract you let walk. Losing the lower scenario (a two-thirds cut, ~$4B in revenue) would have created a hole bigger than the entire FY2025 controllable loss, on top of an existing $9B GAAP loss and an exhausted line of credit.
Why USPS thought it could push Amazon harder
In December 2025, USPS announced it would open access to its 18,000 Destination Delivery Units (DDUs) to competitive bidding — a reverse-auction model in which retailers including Amazon would compete with each other for last-mile capacity at specific facilities.[18][19]Steiner, whose pre-USPS career spanned twelve years as CEO of Waste Management and a long tenure on the FedEx board, framed the move as a way to "establish a fair bidding process that enables the marketplace to find the best mix of local shipping attributes for the best volume-driven pricing."[18]
Amazon's response was unusually pointed. According to reporting in CNN Business, the company argued the auction model created unacceptable uncertainty around capacity and pricing too late in the contracting cycle to reallocate hundreds of millions of packages.[19] By March 2026, Amazon had publicly threatened to cut two-thirds or more of the volume USPS currently delivers for it.[1] Sources told the press that bids from competing retailers came in below USPS expectations, and the agency returned to negotiations on terms much closer to a renewed Negotiated Service Agreement than a true auction.[6][7]
03A 13-year arc — from 2013 to 2026
How Amazon and USPS got here
The April 2026 deal is best understood as a punctuation mark in a thirteen-year relationship that has already swung from breakthrough partnership to public feud to grudging codependence. The basic shape: USPS provides last-mile density Amazon can't economically replicate; Amazon provides volume USPS can't live without.
October 2013
The original Sunday delivery deal
Amazon and USPS strike a five-year contract for Sunday package delivery, initially in Los Angeles and New York. Specific terms remain confidential under standard USPS Negotiated Service Agreement protections, but the deal effectively launches modern Sunday parcel service in the U.S. and seeds Amazon's reliance on USPS for last-mile density.
April 2018
President Trump publicly attacks the contract
Trump tweets that USPS loses $1.50 per Amazon package and calls Amazon a 'Delivery Boy' problem for the Postal Service. Independent fact-checks and the Postal Regulatory Commission's own findings repeatedly conclude the Amazon contract is profitable for USPS at a per-piece basis. The episode foreshadows recurring political risk for the partnership.
2018–2020
Amazon begins pulling its own freight
Amazon launches the Delivery Service Partner (DSP) program in 2018, offering small-business operators capital and routes to run branded last-mile fleets. Amazon Air, founded in 2016 as Prime Air, scales rapidly through deals with ATSG and Atlas Air. By the end of 2020, Amazon Logistics is delivering more than half of Amazon's own packages.
2020–2024
AMZL surpasses UPS and FedEx in U.S. parcel volume
Amazon Logistics' U.S. package volume grows at an estimated 25.8% CAGR from 2019 to 2024, reaching ~6.1B packages in 2024 (ShipMatrix) and surpassing UPS and FedEx in volume share. Amazon expands its DSP base to roughly 4,400 partners and 390,000 drivers across 19 countries.
July 2023
USPS launches Ground Advantage
USPS consolidates Retail Ground, Parcel Select Ground, and First-Class Package Service into a single, simpler Ground Advantage product (2–5 day delivery) — the centerpiece of its Delivering for America package growth strategy. Ground Advantage revenue grows 22% to $4.2B in its first full year and reaches $16.2B (+20.7%) by FY2025.
January 2025
UPS announces it will cut Amazon volume by 50%+
UPS CEO Carol Tomé announces a glide-down of Amazon volume by more than 50% by mid-2026, calling Amazon outbound 'not profitable for us, nor a healthy fit for our network.' Amazon has been UPS's largest customer at 11.8% of 2024 revenue. The move pushes more Amazon volume toward USPS and AMZL — and gives USPS leverage in the next negotiation.
April 30, 2025
Amazon commits $4B to rural delivery network
Amazon pledges over $4 billion to expand its rural delivery network, adding 200 rural delivery stations, creating 100,000 new jobs, and aiming to enable over a billion more packages a year to customers in 13,000 ZIP codes spanning 1.2 million square miles by the end of 2026.
May 9, 2025
David Steiner becomes 76th Postmaster General
The USPS Board of Governors appoints David Steiner — former CEO of Waste Management and a sitting FedEx board member — as Postmaster General. The selection is controversial; the National Association of Letter Carriers calls it 'an aggressive step toward handing America's mail system over to corporate interests.' Steiner takes office in July 2025.
December 2025
USPS announces last-mile competitive bidding
USPS unveils a plan to open access to its 18,000 Destination Delivery Units to a reverse-auction bidding process beginning in early 2026. The goal: drive up per-piece pricing and force shippers — most prominently Amazon — to compete with each other for capacity. Amazon's existing contract is set to expire in October 2026.
March 2026
Amazon threatens a two-thirds cut
Amazon signals publicly that without acceptable terms it will pull two-thirds or more of the package volume USPS currently delivers for it — roughly 1.1B packages annually — and accelerate its own rural delivery and AMZL buildouts. USPS returns to the table.
April 6, 2026
Amazon and USPS announce a deal
Reuters first reports the agreement, which preserves roughly 80% of Amazon's USPS volume — over 1B packages a year — and is described by Amazon as 'furthering our longstanding partnership.' Financial terms are not disclosed. The deal remains tentative pending PRC approval.
What's striking about the timeline is how predictable each step looks in retrospect. Amazon spent eight years building the in-house capacity to walk away from USPS; USPS spent four years (under Delivering for America) building the package products and processing capacity that made it less existentially dependent on Amazon than it was in 2018; both sides arrived at 2026 with enough leverage to credibly threaten a divorce, and both, in the end, blinked.
04What it means for non-Amazon shippers
Three forces are now squeezing Ground Advantage at the same time
For DTC brands and 3PLs that route the bulk of their lightweight residential volume through USPS Ground Advantage, the headline of the deal — "Amazon stays" — is the easy part. The hard part is what happens next. Three things are shifting at the same time, and they all point toward modestly higher all-in cost per parcel and tighter capacity at the DDU level over the next 12–18 months.
Force 1: An 8% temporary surcharge starting April 26, 2026
On March 25, 2026 — eleven days before the Amazon deal was announced — USPS filed for a temporary 8% surcharge on Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select, effective April 26, 2026 and scheduled to remain in place until midnight Central on January 17, 2027.[11] USPS framed the surcharge as a transportation-cost recovery move, noting that "our competitors have reacted with a number of surcharges" and that this charge is "less than one-third of what our competitors charge for fuel alone."[11]
For a typical DTC apparel parcel currently at, say, $7.50 in Ground Advantage (1 lb, Zone 5), this lifts true unit economics by roughly $0.60 per parcel for the rest of 2026. Multiply across a 200,000-parcel year and you're staring at $120K in unbudgeted shipping spend on USPS alone. This is a stand-alone announcement — independent of the Amazon negotiation — but the timing is conspicuous and worth budgeting around.
Force 2: USPS Ground Advantage capacity risk
USPS is already running its package network hot. Ground Advantage volume grew 21% in FY2025 even as overall Shipping and Packages volume fell 5.7% — the Ground Advantage product is absorbing share from declining First-Class Package and from competitor handoff programs.[8] Add to this:
In late 2025, USPS reached a renewed Ground Saver agreement with UPS, re-establishing last-mile handoff for what was historically called UPS SurePost.[20] That handoff had largely shifted in-house at UPS in early 2025; the renewed deal returns a meaningful slug of volume to USPS DDUs.
FedEx Ground Economy (formerly SmartPost) has reduced — but not eliminated — USPS dependency. Lower-pound, deep-zone parcels still hand off to USPS for final mile.
USPS extended Ground Advantage service standards in July 2025, adding one day to delivery for origin ZIPs more than 50 miles from a regional processing and distribution center, and revised internal performance goals downward (e.g., 2-day mail target dropped from 93% to 87%).
Amazon's ~1B preserved packages aren't evenly distributed — they concentrate in residential zones where USPS already has the highest density, i.e., the same zones small DTC brands rely on.
Force 3: Last-mile realignment is still happening, just slower
The deal does not stop Amazon's vertical buildout — it slows it. Amazon still plans to triple its rural delivery network by year-end 2026, adding 200 stations across 13,000 ZIP codes and an area roughly the size of Alaska, California and Texas combined.[15] AMZL volume is projected by Pitney Bowes to surpass USPS by 2028.[14] Amazon Air now operates roughly 95–100 dedicated freighters with capacity up about 14% year over year on the back of A330-300P2F additions through Hawaiian and continued ATSG 767 expansion.[21][22]
Net effect: in 2026 USPS keeps the volume; in 2027–2028 Amazon's rural stations come online and the share Amazon hands to USPS slowly compresses anyway. Non-Amazon shippers should expect Ground Advantage to remain capacity- and price-pressured through 2026, then potentially loosen modestly as Amazon volume migrates in-house through 2027–2028 — assuming USPS doesn't simply absorb the freed capacity with new Ground Advantage growth.
Lock in 2026 USPS rate cards in writing. If you negotiate through a consolidator (Pitney Bowes, EasyPost, Stamps.com, ShipBob, etc.), get an explicit acknowledgment of the April 26 surcharge treatment and any pass-through mechanics for additional in-year filings. Surcharges that "expire" January 17, 2027 have a way of being renewed.
Re-bid your top 5 USPS-substitute lanes with regional carriers (OnTrac, Better Trucks, Veho, GLS, LSO, Pandion) and with FedEx Ground Economy and UPS Ground Saver. The 8% surcharge plus rumored peak surcharges may bring break-even thresholds closer than they were in 2024.
Audit DIM weight exposure. If your average parcel is over ~12 inches in any dimension, re-run the math on dimensional weight under both USPS Ground Advantage and FedEx/UPS Ground rates. USPS DIM exposure has tightened over the past two cycles; the gap to the carriers is smaller than many shippers assume.
Tag your top 100 USPS Destination Delivery Units by 5-digit ZIP and start tracking induction-to-delivery intervals weekly. A capacity squeeze from preserved Amazon volume will show up as DDU-level transit slippage, not as a system-wide announcement.
In the next 180 days
Build a multi-carrier shipping rules engine if you don't already have one. Single-carrier shippers were exposed in the December–March uncertainty window; the next dispute (this contract is tentative and still has Postal Regulatory Commission review ahead of it) will move faster.
Run a peak 2026 stress test in August, not October. Model a scenario where USPS Ground Advantage runs 24–36 hours behind posted service standards in your top 10 destination markets. What does your CX cost look like? Where do you re-route?
Negotiate Saturday and Sunday delivery explicitly. Sunday delivery was the original 2013 Amazon-USPS deal, and it isn't guaranteed for non-Amazon shippers. If your DTC AOV depends on Saturday/Sunday for perceived speed (think apparel, beauty subscription, perishables), get your consolidator to confirm in writing what days your tendered packages will move on for the rest of 2026.
In the next 365 days
Reconsider node count. The most reliable hedge against Ground Advantage transit volatility is geography — moving the average parcel from Zone 5 to Zone 3 cuts cost and shaves a day off transit regardless of who the carrier is. Run a 2-node vs. 3-node vs. 4-node network analysis with current parcel mix and 2026 surcharged USPS rates.
Plan for AMZL capacity to come online for non-Amazon parcels. Amazon currently delivers third-party (Multi-Channel Fulfillment, Buy with Prime) packages on AMZL. As rural stations come online in 2026–2027, MCF and Buy with Prime become legitimate cost levers in zones the regional carriers don't serve well. Rebid them annually.
Re-evaluate carrier mix at the SKU level, not the order level. A 1.5-lb glass-bottle product to a Zone 7 residence is a different problem than a 4-oz envelope to a Zone 3 residence. The simplest single-carrier defaults will be the most expensive defaults in 2026.
06The bigger picture
Codependence, not partnership
The most honest framing of the April 6, 2026 deal is that USPS and Amazon have entered a phase of structural codependence. USPS needs Amazon's revenue and density today; Amazon needs USPS's rural last-mile reach until its own 200 rural stations come online. Neither side likes the position; both are working to escape it on a multi-year timeline.
The economics are genuinely bigger than parcels. USPS delivers prescriptions to roughly 3.7 million Medicare enrollees in pharmacy deserts; per public reporting on the deal, about 6% of diabetes prescriptions reach patients via USPS.[5] The Postal Service is a constitutionally rooted institution carrying ballots, Social Security checks and IRS notices into corners of the country no private network reaches at parity. A failure to renew Amazon would have meant either an unprecedented federal bailout or unprecedented service cuts; both options would have rippled through every other parcel shipper in the country.
Without legislative action, the mail will stop.
For Warpspeed's own clients — DTC brands shipping a few hundred to a few hundred thousand parcels a month — the practical consequence is simple. Don't assume the deal is the end of the story. The contract is tentative. The surcharge is real. The structural drift toward Amazon's in-house network is unchanged. Plan, in 2026, like Ground Advantage rates and capacity will move against you twice more before peak.
The shippers who treated the December–March uncertainty window as a serious risk management exercise — diversifying carriers, locking rates in writing, tagging DDU performance — entered Q2 2026 with options. The shippers who assumed it would all work itself out spent April scrambling to model the April 26 surcharge. Both groups are now doing the same work, just twelve weeks apart.
