The Gulfstream G650 market remains low in available inventory, with transaction activity continuing despite a relatively small pool of aircraft for buyers to choose from. Eight aircraft have sold during the past six months compared with six currently available. However, July brought a noticeable increase in inventory, making the next few months worth watching to see whether those additional aircraft are absorbed or represent the beginning of a broader increase in supply.
Fleet Size and Availability
There are currently 6 Gulfstream G650s available for sale, representing 4.2% of the fleet.
Inventory remained relatively tight through most of the period, with four aircraft available in February and March, five in April, and just three in both May and June. July then saw inventory double from three to six aircraft, the highest level of the six-month period.
While six aircraft still represents limited absolute supply, the July increase gives buyers more options than they have had throughout much of 2026.
Market Listings
Current asking prices range from $30.5 million to $42.95 million, while reported six-month retail sales range from $36.0 million to $36.8 million.
Current listings average 225 days on market, compared with 180 days for recently sold aircraft. The 45-day difference indicates that aircraft successfully trading have generally moved more quickly than the G650s remaining available.
The wide spread in current asking prices also reinforces how individual aircraft specifications can significantly influence value within this market.
Sales Activity
There have been 8 retail sales during the past six months, including 6 off-market transactions, representing 5.6% of the fleet.
Activity was consistent but light early in the period, with one transaction each in February, March, and April. May was the clear standout with four sales, followed by no transactions in June and one in July.
As with several of the larger Gulfstream markets, off-market activity is significant. Six of the eight transactions were completed off-market, meaning publicly visible activity represents only a portion of the G650 market.
Key Takeaways
• 6 aircraft are currently available, representing 4.2% of the fleet.
• Inventory doubled from 3 aircraft in June to 6 in July.
• 8 aircraft sold during the past six months, including 6 off-market transactions.
• May was the strongest month with 4 sales.
• Current listings average 225 DOM, compared with 180 days for recently sold aircraft.
• Asking prices range from $30.5 million to $42.95 million.
Key Insight
The July increase in inventory is the most important development to watch in the G650 market. Six aircraft is hardly excessive supply, but it is double what buyers had available just one month earlier. At the same time, six of the eight recent transactions occurred off-market, reinforcing the importance of understanding opportunities beyond publicly advertised inventory. For sellers, the increase in available aircraft introduces additional competition, making realistic pricing and strong overall aircraft presentation increasingly important. For buyers, the expanded selection could create opportunities, particularly if inventory continues to build into the remainder of the year.
