The ten largest shipping companies in the world, and what the ranking does not tell you.

The ranking, as it stands

Carriers are ranked by operated TEU capacity— the total container slots across the ships a group runs, whether it owns them or charters them. A TEU is one twenty-foot container; a standard household shipment in a sole-use forty-foot container occupies two of them. The figures below are Alphaliner’s, as reported for 4 January 2026.

The concentration at the top is easy to underread. MSC operates 2,524,000 TEU more than Maersk in second place — a gap larger than the entire fleet of Hapag-Lloyd in fifth, and more than three times the whole of Yang Ming in ninth. The top three alone hold 47.2% of world capacity.

Those ten rows sum to 28,445,000 TEU, against a world fleet of 33.690m TEU across 7,498ships. Alphaliner’s own headline for the same release is 28,348,000 TEU, or 84.1% of world capacity. The 97,000 TEU difference is a rounding artefact — per-carrier figures are published to the nearest thousand and a fleet changes daily — and we mention it because a page about accurate numbers should explain its own.

Why two “top ten” lists disagree

Search for this ranking and you will find versions that contradict each other. Usually neither is wrong: they consolidate differently. Alphaliner counts subsidiary brands towards the parent group, so a shipment moving on an APL bill of lading counts towards CMA CGM, and one on Hamburg Süd counts towards Maersk. A list that treats those as separate carriers produces a different order.

This matters beyond trivia. If a moving company tells you your container is booked with a line you cannot find in any ranking, it is very often a consolidated brand rather than an obscure operator.

The number the rankings leave out

Fleet size tells you how much a carrier can move. It tells you nothing about whether a ship turns up on the day the schedule says. That measure is called schedule reliability: the share of vessel arrivals landing inside the advertised window. Sea-Intelligence publishes it monthly, and it is close to absent from articles ranking the same carriers by size.

For July 2026, global schedule reliability was 56.4% — down 6.1 percentage points on the month and 8.8 on the year. Ships that did arrive late averaged 6.06 days behind schedule.

The spread is the point. Between the most and least reliable carrier in a single month there is a gap of 43.9 percentage points. Neither the best nor the worst performer is the largest carrier, and the two most reliable are not the two biggest. Size and punctuality are separate properties.

The alliances matter more than the rank

Carriers share vessels through alliances, so the line that sold the slot is frequently not the line whose ship carries the box. The groupings were rebuilt in February 2025, when the 2M partnership between Maersk and MSC ended.

The practical consequence: booking with a Gemini member does not guarantee a Gemini ship on every leg, and a delay on a shared service affects every carrier selling space on it. When a schedule slips, the question worth asking is which service the container is on, not which brand issued the paperwork.

What this means for a household move

Almost nobody moving a home contracts with these carriers directly. Household shipments are booked through moving companies and consolidators who hold the relationship with the line. You will generally not choose your carrier, and a mover promising a specific one is describing an intention rather than a guarantee — space is allocated when the shipment is ready, not when the quote is signed.

That does not make the ranking useless. It tells you which names should be recognisable on your documents, and the reliability data tells you what to build into a plan. Ask these questions instead of asking for a carrier by name.

Our guide to international moving times sets out the stages a door-to-door estimate has to cover, and comparing moving quotes explains how to check that two estimates describe the same scope.

How these figures were compiled

Capacity figures are Alphaliner’s consolidated operated-capacity ranking as reported for 4 January 2026, cross-checked against two independent write-ups of the same release which agree on the leading positions and the combined total. Schedule reliability is from Sea-Intelligence’s Global Liner Performance report covering July 2026, published 27 August 2026. Alliance membership is as constituted from February 2025.

Capacity rankings change continuously as ships are delivered, chartered and redelivered, and schedule reliability is republished monthly. Treat every figure here as carrying the date attached to it rather than as a live number. We revisit the page when a top-ten position changes hands, when monthly reliability moves by more than five percentage points, or when an alliance membership changes.

We have no commercial relationship with any carrier named on this page, and no carrier pays for its position in the table or the way it is described.
