The Gulfstream GIV-SP occupies a unique position in the pre-owned large-cabin market. As the direct predecessor to the Gulfstream GV and a refinement of the successful GIV platform, the GIV-SP combines long-range capability, generous cabin dimensions, and proven operational reliability. Today, it remains a popular choice among buyers seeking a large-cabin aircraft with global capability at a fraction of the acquisition cost of newer-generation business jets.
Fleet Size and Availability
There are currently 23 Gulfstream GIV-SP aircraft available for sale worldwide, representing 8.0% of the global fleet.
Inventory has moderated over the past several months, declining from a peak of 33 aircraft available in February 2026 to 25 aircraft in May, before settling at the current level of 23 aircraft. While availability remains elevated compared to newer Gulfstream models, the recent reduction suggests that buyer demand continues to absorb inventory at a healthy pace.
With less than 10% of the fleet currently available for sale, the market remains relatively balanced for a mature aircraft category.
Market Listings
Current asking prices range from $2,795,000 to $6,800,000, with active listings averaging 240 days on market.
Values continue to be heavily influenced by maintenance status, avionics upgrades, engine program enrollment, refurbishment history, and regulatory compliance. Aircraft with modernized flight decks, upgraded cabins, and favorable maintenance positions continue to attract stronger buyer interest and command premium pricing.
Current marketing times suggest buyers remain active but highly selective, particularly when evaluating older large-cabin aircraft.
Sales Activity
Over the past six months, 38 Gulfstream GIV-SP aircraft have sold, including 13 off-market transactions, representing 13.2% of the fleet. Reported transaction values ranged from $2,800,000 to $6,800,000, with sold aircraft averaging 276 days on market.
Sales activity has been particularly impressive relative to the size of the fleet, with more than 13% of all aircraft changing ownership during the reporting period. Off-market transactions accounted for approximately one-third of all reported sales, demonstrating continued demand among buyers utilizing broker networks and direct acquisition channels.
Following a slower first quarter, transaction activity accelerated during April and May, indicating renewed buyer interest within the segment.

Key Insight
The Gulfstream GIV-SP market continues to demonstrate strong transaction velocity for a legacy large-cabin aircraft. While inventory remains meaningful, sales activity has been robust and recent inventory reductions suggest improving market balance. Buyers continue to focus on aircraft with strong maintenance pedigrees and modern upgrades, while sellers with well-positioned aircraft remain capable of attracting serious market interest despite the competitive landscape.
