The global aircraft turbofan engine market was valued at USD 108 billion in 2025. The market is projected to grow from USD 114.5 billion in 2026 to USD 175 billion by 2034, exhibiting a compound annual growth rate of 5.44% during the forecast period. Contrive Datum Insights presents this information in its report titled "Aircraft Turbofan Engine Market Size, Share & Industry Analysis, By Turbofan engine (PW1000, F414, V2500, PW4000, CFM56, CFM LeapX, GP7000, GEnx, Trent 1000, F135, Others), Application (Military Aviation, Commercial Air Transport, Others), Aircraft type (Wide Body, Narrow Body, Others), End user (OEM, Aftermarket), Technology (Conventional, Geared Turbofan), and Regional Forecast, 2026-2034".
A turbofan engine is the primary propulsion system fitted to commercial airliners, military transport and combat aircraft, and regional jets, combining a ducted fan with a gas-turbine core to generate thrust efficiently across a wide range of speeds and altitudes. Airframers select and integrate a specific engine model into each aircraft program at the design stage, and airlines, leasing companies, air forces and maintenance providers then purchase new engines, spare parts and overhaul services across the aircraft's operating life. Buyers range from commercial airlines renewing narrowbody and widebody fleets to defense ministries procuring fighter and transport aircraft.
Narrowbody re-engining under A320neo and 737 MAX ramp-up
Narrowbody re-engining under A320neo and 737 MAX ramp-up is the largest single contributor to the market's growth over the forecast period, and the study rates its impact high. Against a market growing at 5.44% a year, the turbofan engine lines exposed to it move fastest: PW1000 compounds at 10.72%, taking its share of revenue from 14% to 22% and its value from USD 15.12 billion to USD 38.5 billion.
On the upside, the study's bull case assumes the bull case assumes narrowbody production rates recover faster than currently scheduled and the supply-chain constraint on forgings and castings eases earlier than planned, pulling forward OEM deliveries and the aftermarket demand that follows them, which would take 2034 revenue to USD 190 billion against the USD 175 billion base case.
The downside is specific. The bear case assumes continued supply-chain constraints hold narrowbody production rates below current airframer targets through the period and defense budgets delay fighter engine procurement, slowing both OEM and aftermarket revenue growth, and 2034 revenue lands at USD 160 billion. CFM56 is the drag, 22% of the 2025 base compounding at -3.71% while the market runs at 5.44%.
The Competitive Split Runs by Turbofan engine
Two positions matter, and they are set by turbofan engine. CFM56 carries 22% of 2025 revenue (USD 23.76 billion) and is still the largest line in 2034 at 10%, hard to take from an incumbent. PW1000, at 10.72%, is where the USD 108 billion base is redistributed. The two demand different capabilities.
