The Gulfstream G450 remains one of the most respected large-cabin business jets in the pre-owned market. Combining transcontinental and intercontinental capability with Gulfstream’s renowned cabin comfort, dispatch reliability, and operating pedigree, the G450 continues to attract interest from corporate flight departments, private owners, and international operators. Although newer Gulfstream models have entered the market, the G450’s performance and value proposition continue to support steady demand.
Fleet Size and Availability
There are currently 17 Gulfstream G450 aircraft available for sale, representing 4.8% of the fleet.
Inventory levels have remained remarkably stable throughout the first half of 2026, fluctuating between 15 and 18 aircraft. The consistency in available inventory suggests a balanced marketplace where new listings are generally being absorbed by buyers at a pace similar to supply entering the market.
With fewer than 5% of the fleet currently available, the G450 remains a relatively constrained market compared to historical large-cabin inventory levels.
Market Listings
Current asking prices range from $8,750,000 to $19,995,000, with active listings averaging 147 days on market.
The wide valuation range reflects the diversity within the G450 fleet. Aircraft age, total time, maintenance status, engine program participation, interior refurbishment history, and avionics configuration continue to be primary value drivers. Newer aircraft with comprehensive maintenance coverage and updated interiors generally command the strongest pricing.
Current marketing times indicate buyers remain active, particularly for aircraft that present strong maintenance positions and competitive pricing.
Sales Activity
Over the past six months, 18 Gulfstream G450 aircraft have sold, including 3 off-market transactions, representing 5.1% of the fleet. Recorded sales ranged from $9,000,000 to $18,600,000, with sold aircraft averaging 135 days on market.
Sales activity has remained steady despite broader economic uncertainty and higher acquisition costs associated with large-cabin aircraft. Transaction volume has closely matched current inventory levels, demonstrating continued market liquidity and sustained buyer demand.
Notably, sales activity accelerated during the spring months, with six aircraft changing hands in May alone, the highest monthly total of the reporting period.
Key Takeaways
• Seventeen aircraft are currently available worldwide, representing 4.8% of the fleet
• Inventory has remained stable between 15 and 18 aircraft throughout the year
• Eighteen aircraft sold during the past six months, including three off-market transactions
• Sold aircraft averaged 135 days on market, slightly faster than active listings

Key Insight
The Gulfstream G450 market remains balanced and healthy, with transaction volume closely tracking available inventory. Stable supply levels, consistent sales activity, and reasonable marketing times indicate a market where both buyers and sellers can transact efficiently. While buyers have meaningful selection available, high-quality aircraft with strong maintenance pedigrees continue to generate significant interest, helping preserve values across much of the fleet.
