The Gulfstream GIV-SP market continues demonstrating steady transactional activity as buyers pursue proven large-cabin capability at acquisition costs well below newer-generation ultra-long-range aircraft. The model remains attractive for operators prioritizing cabin comfort, transcontinental range, and operational reliability, particularly when paired with modern avionics upgrades and strong maintenance pedigree.
Fleet Size and Availability
There are currently 24 Gulfstream GIV-SP aircraft for sale, representing 8.3% of the fleet.
Inventory levels have declined meaningfully from late 2025 highs, falling from 43 aircraft in November to 25 aircraft by April. This steady reduction in available inventory reflects improving market absorption and sustained buyer demand within the legacy large-cabin segment.
While inventory remains higher than more modern Gulfstream platforms, the downward trend suggests the market is continuing to normalize as buyers capitalize on favorable value opportunities.
Market Listings
Current asking prices range from $2,795,000 to $6,500,000, with aircraft averaging 256 days on market.
Pricing remains highly dependent on engine enrollment status, avionics modernization, maintenance compliance, and interior refurbishment quality. Aircraft upgraded with modern flight decks and fresh major inspections continue commanding stronger buyer attention and improved liquidity.
Average days on market indicate buyers remain selective, though transaction timelines remain reasonable relative to comparable legacy large-cabin aircraft.
Sales Activity
Over the past six months, 37 Gulfstream GIV-SP aircraft have sold, including 12 off-market transactions, representing 12.8% of the fleet. Sold aircraft traded between $2,800,000 and $6,800,000.
Sales activity accelerated notably in April following a slower February and March, suggesting renewed buyer momentum entering the second quarter. Off-market transactions accounted for nearly one-third of completed sales, reinforcing the importance of broker networks and private deal flow within this segment.
Sold aircraft averaged 277 days on market, indicating that even completed transactions often require extended marketing exposure due to detailed buyer evaluation processes surrounding maintenance and operating costs.
Key Takeaways
• Inventory levels continue trending downward from late 2025 highs
• Buyers remain focused on upgraded aircraft with strong maintenance pedigree
• Off-market activity continues representing a significant portion of total transactions
• Market absorption remains healthy despite extended marketing periods
• The GIV-SP continues offering strong value within the large-cabin segment
Key Insight
The Gulfstream GIV-SP market continues benefiting from value-oriented demand as operators seek large-cabin capability without the acquisition premiums associated with newer aircraft. While buyers remain highly selective regarding maintenance status and avionics modernization, the continued reduction in inventory and strong six-month sales volume indicate the platform remains highly relevant in today’s secondary market. Well-equipped aircraft with upgraded systems and documented maintenance continue outperforming the broader market and maintaining the strongest liquidity.
