Comac fleet share seen rising to 5% by 2045

The forecast matters because aircraft production is one of the clearest long-cycle barometers of industrial power, trade leverage and capital spending. A 5% share is still modest against Airbus and Boeing, but in a sector where fleet decisions stretch over decades and imply thousands of aircraft deliveries, it signals that Beijing’s push to build a domestic aerospace champion is beginning to translate into measurable global presence.

For investors, the implication is two-sided. On one hand, the numbers suggest Comac is unlikely to dislodge the incumbents in the near term, which supports the thesis that Airbus and Boeing will continue to dominate backlogs, pricing power and aftermarket economics. On the other, even a gradual shift toward Chinese-built aircraft could chip away at future growth opportunities in the world’s largest aviation market, especially if domestic carriers increasingly favor local suppliers.

The market backdrop reinforces that tension. Airbus has been lifting deliveries and faces pressure to hit its ambitious 2026 target of 870 aircraft, while supply-chain bottlenecks continue to constrain production across the sector. Boeing, meanwhile, is still navigating operational and certification issues that have weighed on sentiment and production confidence. Against that backdrop, any rise in Comac’s competitive footprint is more important than the raw share figure might suggest, because it arrives just as Western manufacturers are trying to convert strong demand into higher output.

Cirium’s language — a “gradual shift” alongside the persistence of Airbus and Boeing concentration — captures the likely shape of the next phase in commercial aviation: not a revolution, but a slow redistribution of orders, assembly know-how and strategic influence. The C919 is expected to lead that effort for China, and while its international penetration is likely to remain limited in the near term, the domestic market alone gives Comac a powerful base from which to scale.

That leaves the next 20 years as a test of execution rather than ambition. If Comac can build reliability, expand certification acceptance and deepen its supply chain, the 5% forecast may prove conservative. If not, Airbus and Boeing will remain the dominant beneficiaries of global air travel growth, with China’s challenge staying largely regional rather than systemic.
