The three major ocean container alliances in 2026 are Gemini Cooperation (Maersk + Hapag-Lloyd, launched 1 February 2025), Premier Alliance (ONE + HMM + Yang Ming, formed February 2025 after MSC's exit from 2M), and Ocean Alliance (CMA CGM + COSCO + Evergreen + OOCL, extended through 2032 and now operating under the DAY 10 2026 product update). MSC, the world's largest container carrier by fleet capacity, now operates fully standalone after choosing not to renew 2M with Maersk. Together these four groupings (three alliances plus MSC standalone) move the overwhelming majority of east west container capacity between Asia, Europe, and North America. This article explains who is in each alliance, what capacity share they carry, which trade lanes they cover, how the 2025 reshuffle changed service strings, and the operational playbook for a forwarder whose booked service string was discontinued, replaced, or re rotated under the reshuffle.
Definition
An ocean carrier alliance is a vessel sharing agreement between two or more container shipping lines that lets each partner sell space on the other partners' vessels while each keeps its own commercial book of business. Partners pool vessels, port rotations, and slot capacity on named service strings, then divide the slots by contractual share. The shipper still books through, and pays, its named carrier. The physical vessel and the physical route are the alliance's.
Three things alliances share. Ships, so each carrier can offer coverage on lanes it does not fully operate alone. Ports and rotations, so each carrier's customer touches the same terminals on the same day of week. Slot capacity, so each partner sells a fixed percent of TEU on each vessel departure. Three things alliances do not share. Sell rate, which each carrier sets alone under its own contract. Customer relationships, which stay with the contracting carrier. Commercial risk, which each carrier absorbs on its own book.
The point of an alliance for the carrier is capacity efficiency (bigger vessels justify their capex only if slot utilisation stays high) and coverage breadth (each carrier offers more lanes than it operates alone). The point for the shipper is more frequent departures per week per lane and, in principle, more predictable transit times.
The 2016 alliance structure (2M, Ocean Alliance, THE Alliance) ran for close to nine years. In January 2025 it ended.
The reshuffle was not a name change. It was a physical reshuffle of ports called, vessel deployments, service string codes, day of week rotations, and terminal windows. On many lanes the calling port order, the transit time, and the day cargo hits your final port are all different from what the same booking looked like in Q4 2024.
Watch out
On many lanes the calling port order, the transit time, and the day cargo hits your final port are all different from what the same booking looked like in Q4 2024. Every deck, capabilities one pager, and RFP response referencing 2M, THE Alliance, or the pre 2025 alliance structure is out of date.
The table below is the extractable object of this article. Four rows (three alliances + MSC standalone), five columns, everything a shipper or forwarder needs to compare on one screen.
| Alliance | Members | Approx TEU Capacity Share | Primary East West Coverage | Service Quality & Rate Posture (2026) |
|---|---|---|---|---|
| Gemini Cooperation | Maersk, Hapag-Lloyd | ~22 percent | Asia to North Europe, Asia to Med, transpacific (both coasts), transatlantic | Hub and spoke network. Marketed schedule reliability >90 percent target. Rate posture: premium reliability play, not lowest rate |
| Premier Alliance | Ocean Network Express (ONE), HMM, Yang Ming | ~12 percent | Asia to North Europe, transpacific, transatlantic. Reduced Med coverage vs legacy THE Alliance | Rate follower. Broad east west coverage. Schedule reliability historically mid pack, rebuilding after reshuffle |
| Ocean Alliance | CMA CGM, COSCO, Evergreen, OOCL | ~32 percent | Asia to North Europe, Asia to Med, transpacific (both coasts), transatlantic, plus intra Asia | Largest east west alliance by TEU deployed. Extended through 2032. DAY 10 2026 product update in effect. Balanced rate and service posture |
| MSC (standalone) | MSC | ~20 percent | Global. World's largest single carrier fleet. Covers every east west lane on its own network | Direct booking. Rate leader on some lanes (MSC uses scale to price competitively), premium on others. Not an alliance member |
The three alliances plus MSC standalone together account for roughly 86 percent of global TEU capacity. Regional carriers (Wan Hai, PIL, ZIM, and others) cover the balance and typically play into intra Asia, niche Asia to Med, and some transatlantic strings.
Gemini Cooperation is a two carrier alliance. Maersk (approx 15 percent global TEU capacity share) and Hapag-Lloyd (approx 7 percent), each running under its own commercial book but sharing vessels and rotations on named service strings.
Gemini's design principle is hub and spoke. Rather than run direct calls at every major port on every string, the alliance concentrates east west line haul at a small set of primary hubs and feeds regional ports with shuttle services from those hubs. That structure lets the mother vessels keep tighter rotations, which is where the >90 percent schedule reliability marketing claim comes from.
Typical Gemini east west coverage in 2026:
The precise service string codes, day of week cutoffs, and vessel deployments update quarterly.
Gemini's marketed reliability target has been the single most visible reshuffle claim. Sea-Intelligence and other public schedule reliability trackers have shown Gemini above the industry average through 2025 and into 2026, though not consistently at the 90 percent threshold across all strings. Rate posture is a reliability premium play. On lanes where a shipper needs a defensible on time in full number for its own downstream commitments, Gemini strings win business on reliability rather than price.
Premier Alliance is the three carrier successor to THE Alliance minus Hapag-Lloyd. Ocean Network Express (ONE, roughly 6 percent global TEU), HMM (roughly 3 percent), and Yang Ming (roughly 3 percent). Combined share ~12 percent of global TEU. The alliance name change (THE to Premier) took effect in February 2025.
Premier Alliance runs broad east west coverage with fewer service strings than the legacy THE Alliance had while Hapag-Lloyd was still a partner. Typical coverage:
Premier Alliance's post reshuffle reliability numbers have been mid pack in public trackers. The reshuffle disrupted the string mix Yang Ming, ONE, and HMM ran under THE Alliance and the network has been rebuilding through 2025 to 2026. Rate posture is a follower play. Premier tends to price competitively on transpacific and Asia to Europe lanes to protect capacity fill, and the alliance is a common option on FMC filed contracts where the shipper wants three or more carriers named.
Ocean Alliance is the largest east west alliance by combined TEU capacity deployed. Four carriers: CMA CGM (roughly 13 percent global TEU), COSCO (roughly 11 percent), Evergreen (roughly 5 percent), and OOCL (roughly 3 percent, majority owned by COSCO but operated under the OOCL brand). Combined share ~32 percent of global TEU.
Ocean Alliance publishes an annual product update under a "DAY" branding (DAY 1 was the 2017 launch product, so DAY 10 corresponds to the tenth product year taking effect from Q1 2026). The DAY 10 2026 product refresh followed the June 2024 announcement that Ocean Alliance had been extended through 2032, giving the four members a much longer horizon than the two remaining alliances or the two carrier Gemini partnership.
The DAY 10 2026 update refreshed:
The DAY 10 branding is the exact phrase shippers and forwarders search for when they want the current year's Ocean Alliance service string map. The product refresh does not change the alliance's four member composition and does not change the underlying agreement extension through 2032.
Ocean Alliance runs the broadest string network of any single alliance in 2026:
Ocean Alliance reliability has held in the industry mid to upper range in public schedule reliability trackers post reshuffle. Rate posture is balanced. The alliance's scale gives its members pricing flexibility on both spot and contract, and the extended 2032 agreement horizon is a marketed stability point for shippers negotiating multi year contracts.
MSC's decision not to renew 2M with Maersk and to operate standalone from 2025 was the strategic move that triggered the full alliance reshuffle. MSC is now the world's largest single carrier by fleet capacity (approx 20 percent of global TEU) and it competes on the strength of that fleet plus a large newbuild orderbook rather than on shared vessel arrangements.
Practical shipper implications:
MSC standalone plus the three alliances is the full 2026 competitive set. Regional carriers (Wan Hai, PIL, ZIM, and others) supplement on specific lanes and are relevant on intra Asia, some Asia to Med, and some transatlantic strings.
Three visible transit time and reliability effects across 2025 to 2026:
Every ocean forwarder with volume on legacy 2M or THE Alliance strings had at least one customer service string discontinued, replaced, or re rotated between Q1 2025 and Q3 2026. Nine step playbook when it happens:
STEP 1
Confirm the change in writing from the carrier.
Alliance re rotation notices come through the carrier account manager, not through the alliance. Get the new string code, the effective sailing date, the port rotation change, and the new day of week cutoff in writing.
STEP 2
Cross reference against your booked pipeline.
Pull every open booking with the affected origin destination and carrier from your freight management platform. Flag the ones sailing after the effective date.
STEP 3
Recalculate transit time and ETA per booking.
New rotation, new hub call, new day of week cutoff typically means new ETA. Recalculate on the shipment record and push the update to your shipper self service surface.
STEP 4
Notify the affected shippers.
One email per shipper with the affected bookings listed, the new ETA per booking, the new port of discharge if changed, and the operational contact if the shipper wants to discuss.
STEP 5
Check the customs filing timing.
New arrival day means new ISF, AES, ACE, or ICS2 filing deadlines. Update filing schedules for affected shipments.
STEP 6
Re confirm the drayage appointment.
If port of discharge or arrival day changed, the drayage appointment is stale. Book the new appointment window with your drayage TMS or trucker.
STEP 7
Check contract volume commitments.
If the alliance re rotation moved volume off your named account contract onto a different carrier or string, check MQC (minimum quantity commitment) exposure and re balance bookings if possible.
STEP 8
Log the change against the affected lane in your rate management system.
Alliance re rotations often move the competitive rate picture on the lane. Update your buy sell rate calibration.
STEP 9
Publish the change internally.
One page ops note per affected string. New rotation, new day cutoff, new ETA logic, effective date. So the next shipper enquiry on the same string does not restart the diagnosis.
Every step in the playbook lands on the same prerequisite: a freight management platform that carries carrier, service string, vessel schedule, and container milestones on one shipment record. Without that, step 2 (cross reference against your booked pipeline) is a spreadsheet exercise across three inbox threads per shipment.
For the underlying platform capabilities that carry this playbook, see the Ocean Freight Management Software feature requirements guide.
Alliance name does not set your rate. The carrier does. But alliance membership shapes the rate posture the carrier can offer:
Ocean carrier alliances operate under regulatory oversight in each of the trade lanes they serve. Two regimes matter most:
Neither regulator has moved to break up any of the three current alliances. Both have signalled tighter scrutiny of alliance behaviour post 2025.
Six operational moves any forwarder with meaningful ocean volume should have completed by Q4 2026:
For the full workflow the ops team should run against every ocean booking after a reshuffle event, see Common Challenges in Freight Forwarding Operations.
Ship Faster. Scale Smarter.
See how GoFreight lets your ops team carry Gemini Cooperation, Premier Alliance, Ocean Alliance DAY 10, and MSC standalone bookings on one cloud based freight management platform. Service string changes, day of week rotation shifts, drayage appointment updates, and customer notifications all land against the same shipment record. Nothing gets lost when the alliance re rotates.
What are the three ocean carrier alliances in 2026?
The three major ocean container alliances in 2026 are Gemini Cooperation (Maersk + Hapag-Lloyd, launched 1 February 2025), Premier Alliance (ONE + HMM + Yang Ming, formed February 2025), and Ocean Alliance (CMA CGM + COSCO + Evergreen + OOCL, extended through 2032 and operating under the DAY 10 2026 product update). MSC operates fully standalone. Together the four groupings (three alliances plus MSC) carry approximately 86 percent of global TEU capacity.
When did Gemini Cooperation launch and who is in it?
Gemini Cooperation launched on 1 February 2025 with two members: Maersk and Hapag-Lloyd. Combined the two carriers pool approximately 22 percent of global TEU capacity. The alliance runs a hub and spoke network engineered for schedule reliability, with a marketed target of greater than 90 percent on time performance across major east west strings.
Why did MSC leave 2M and go standalone?
MSC and Maersk announced in January 2023 that they would not renew the 2M Alliance past its 26 January 2025 expiry. MSC's public rationale centred on its growth trajectory (large newbuild orderbook, fastest fleet expansion of any container carrier through the 2020s) which had made continued vessel sharing with Maersk less strategically necessary. MSC now operates as the world's largest single carrier at approximately 20 percent of global TEU capacity and covers every east west lane on its own network.
What is Ocean Alliance DAY 10 2026?
DAY 10 is the tenth annual product update from Ocean Alliance, taking effect in Q1 2026. Ocean Alliance publishes an annual product refresh under a "DAY" branding (DAY 1 was the 2017 founding product). The DAY 10 2026 update refreshed service string mix, port rotations, and day of week cutoffs across Asia to North Europe, Asia to Mediterranean, transpacific (both US coasts), and transatlantic strings. DAY 10 does not change the four member composition (CMA CGM, COSCO, Evergreen, OOCL) and does not change the underlying agreement extension through 2032 announced in June 2024.
Which alliance is the most reliable in 2026?
Public schedule reliability trackers have shown Gemini Cooperation at or near the top of the industry through 2025 and 2026, consistent with its hub and spoke design and its marketed >90 percent reliability target. Ocean Alliance has held mid to upper industry range. Premier Alliance has been mid pack, rebuilding after the reshuffle disrupted the legacy THE Alliance string mix. MSC standalone reliability varies by lane and is broadly in the industry mid range.
My customer's service string was discontinued or re rotated. What do I do?
Nine step response: (1) confirm the change in writing from the carrier, (2) cross reference against your booked pipeline, (3) recalculate transit time and ETA per booking, (4) notify affected shippers, (5) check customs filing timing, (6) re confirm drayage appointments, (7) check contract volume commitments, (8) log the change against the affected lane in your rate management system, (9) publish the change internally. Full playbook in the "The Alliance Changed My Service String" section above.
Does alliance choice affect my rate?
Alliance name does not set your rate; the carrier does. But alliance membership shapes the rate posture the carrier can offer. Gemini positions on reliability premium, Premier on rate follower economics, Ocean Alliance on balanced scale, and MSC standalone on independent flexibility. Match the alliance to the reliability versus rate trade off your customer actually needs on each lane rather than to alliance name recognition.
What was 2M Alliance?
2M was the two carrier vessel sharing agreement between Maersk and MSC that operated from 2015 through 26 January 2025. At its dissolution, 2M was the largest alliance by combined TEU capacity. Both carriers announced in January 2023 that they would not renew. Maersk moved into Gemini Cooperation with Hapag-Lloyd; MSC moved to standalone operations.
What happened to THE Alliance?
THE Alliance was a four carrier vessel sharing agreement between Hapag-Lloyd, ONE, HMM, and Yang Ming that operated from 2017 through the 2025 reshuffle. When Hapag-Lloyd exited to join Gemini Cooperation in February 2025, the three remaining members (ONE, HMM, Yang Ming) rebranded and continued as Premier Alliance. There is no longer a THE Alliance in the market.
Which alliance covers which trade lane best?
Every alliance and MSC standalone runs weekly service on the major east west lanes (Asia to North Europe, Asia to Mediterranean, transpacific eastbound to both US coasts, transatlantic westbound). Coverage depth differs. Ocean Alliance runs the broadest string count across all east west lanes and the widest intra Asia coverage. Gemini runs a tighter string count concentrated on hub calls with reliability as the differentiator. Premier runs fewer strings than the legacy THE Alliance, particularly on Asia to Mediterranean. MSC standalone covers every east west lane on its own vessels with the highest departure frequency any single carrier can offer. The right choice depends on the specific origin destination pair, the reliability target, and the rate posture your customer needs.
