Three alliances and two large independents carry almost everything that moves in a container. Which one your carrier belongs to decides your routing, your transhipment points and — as of 2026 — your odds of arriving on time by a margin that has become impossible to ignore.
Verified against carrier announcements and trade press on 16 August 2026. Alliance membership is stable, but capacity figures move monthly and the reliability series is updated monthly — re-check before relying on any number here.
The line-up
| Alliance | Members | Term runs to | Model |
|---|---|---|---|
| Gemini Cooperation | Maersk, Hapag-Lloyd | 2030 | Hub-and-spoke: mainline loops call only at partner-controlled hubs, shuttles cover the rest |
| Ocean Alliance | CMA CGM, COSCO, OOCL, Evergreen | 2032 | Traditional multi-stop strings, the broadest direct-call network |
| Premier Alliance | ONE, HMM, Yang Ming | 2030 | Restructured April 2026 toward partial hub-and-spoke, concentrated on Shanghai and Busan |
| MSC | Independent | — | Largest carrier in the world, standalone global network |
| ZIM | Independent | — | Niche and Transpacific focus, with vessel-sharing on six Transpacific services with MSC |
Two details that comparison articles routinely get wrong. MSC is not a Premier Alliance member — it runs a slot exchange with Premier on nine Asia-Europe services, and that is the whole extent of it. And OOCL signs the Ocean Alliance agreement separately from COSCO despite being COSCO-owned.
Nothing has changed since February 2025 — and that is the point
The current structure took effect in February 2025, when Maersk and Hapag-Lloyd left their previous partners to form Gemini. Since then: no new members, no departures, no announced reshuffle, and the nearest expiry is 2030. Ocean Alliance extended all the way to 2032.
What did change in 2026 is network design rather than membership — Gemini added calls from April 2026, Ocean Alliance adjusted services, and Premier restructured on 1 April. If you were told your service changed this spring, that is why.
Capacity: the top ten
| # | Carrier | TEU capacity | Share | Alliance |
|---|---|---|---|---|
| 1 | MSC | 7,318,632 | 21.6% | Independent |
| 2 | Maersk | 4,647,588 | 13.7% | Gemini |
| 3 | CMA CGM | 4,273,202 | 12.6% | Ocean Alliance |
| 4 | COSCO | 3,593,746 | 10.6% | Ocean Alliance |
| 5 | Hapag-Lloyd | 2,400,946 | 7.1% | Gemini |
| 6 | ONE | 2,134,872 | 6.3% | Premier |
| 7 | Evergreen | 1,973,231 | 5.8% | Ocean Alliance |
| 8 | HMM | 1,029,773 | 3.0% | Premier |
| 9 | Yang Ming | 741,908 | 2.2% | Premier |
| 10 | ZIM | 698,205 | 2.1% | Independent |
Alphaliner, as of April 2026. OOCL is consolidated into COSCO. MSC has since passed 1,000 vessels — the first carrier ever to do so — and CMA CGM was the fastest-growing top-ten carrier in the first half of 2026, up 5.7%.
The reliability gap is the real story
Gemini was built around a promise of at least 90% schedule reliability, achieved by cutting the number of mainline port calls so there are fewer places for delay to accumulate. That is a bold claim, and independent measurement has broadly borne it out:
| May/June 2026 schedule reliability | |
|---|---|
| Gemini Cooperation | 93.4% |
| MSC | 80.7% |
| Ocean Alliance | 67.6% |
| Premier Alliance | 53.6% |
| Global average, June 2026 | 62.6% |
Sea-Intelligence Global Liner Performance, issue 179, published 28 July 2026. Average delay for late arrivals: 5.31 days.
A forty-point spread between the best and worst alliance is not a rounding difference — it is the difference between planning inventory around an ETA and treating the ETA as a suggestion.
Two honest caveats. Gemini has not been above 90% continuously: it dipped to 76.8% in the February/March 2026 window before recovering. "Most reliable alliance in every month of 2026" is accurate; "consistently above 90%" is not. And Sea-Intelligence changed its reporting basis from July 2026, so figures either side of that are not strictly like-for-like.
The one change actually in play: Hapag-Lloyd and ZIM
Hapag-Lloyd agreed in February 2026 to acquire ZIM for about $4.2 billion, and ZIM shareholders approved in April with over 97% in favour. The deal has not closed, and as of August 2026 it is genuinely uncertain. It requires clearance in more than 40 jurisdictions plus Israeli government approval under a special state share, and several Israeli ministries are reported to oppose it. An inter-agency decision was postponed to 9 September 2026. Hapag-Lloyd still publicly targets closing by year end.
If it completes, no alliance loses a member — both parties' alliance positions are unaffected — but ZIM volumes would migrate onto the Gemini network and its Transpacific vessel-sharing with MSC would be expected to unwind. That would be a real capacity shift on the Transpacific.
What this means for your bookings
- Ask which alliance and which service, not just which carrier. The alliance determines whether you get a direct call or a transhipment.
- Direct calls beat transhipment for reliability and for damage risk. Gemini's model deliberately trades direct calls for reliability, so on some ports you gain punctuality and lose directness.
- Price reliability against inventory cost. If a 62% chance of on-time arrival forces you to hold two extra weeks of safety stock, the cheaper freight is not cheaper.
- Do not assume the schedule is the transit. Use the transit time estimator for planning and add a buffer sized to the carrier's actual performance.
- Alliance concentration cuts both ways. When one alliance restructures, whole lanes change at once — as they did in April 2026.
