Gulfstream G650ER Market Update September 2026

September 2026 Gulfstream G650ER Market Report - The Jet Agent

The Gulfstream G650ER market enters September with inventory continuing to build, while transaction activity has slowed from its mid-year peak. Eight aircraft are currently available for sale, representing just 1.8% of the fleet, while 14 aircraft have sold during the past six months. Despite the recent increase in listings, overall availability remains low relative to the size of the fleet.

Fleet Size and Availability

There are currently eight Gulfstream G650ERs available for sale, representing 1.8% of the fleet.

Inventory has increased steadily over the past several months. Four aircraft were available in both March and April, increasing to six in May and June, seven in July and nine in August. This represents more than a doubling of publicly tracked inventory since March.

Even with that increase, however, less than 2% of the fleet is currently available, keeping overall supply relatively constrained.

Market Listings

Current asking prices range from $45.75 million to $55.0 million, while reported transactions during the past six months ranged from $41.0 million to $62.4 million.

Current listings average just 70 days on market, compared with 88 days for aircraft sold during the past six months. Unlike several other large-cabin markets, today’s G650ER inventory has not yet accumulated significant market time.

The wide range of recent transaction prices also highlights the importance of aircraft year, configuration, condition and individual specifications when evaluating G650ER values.

Sales Activity

There have been 14 retail sales during the past six months, including seven off-market transactions, representing 3.1% of the fleet.

Monthly activity has varied considerably. March recorded one transaction, followed by three in April and one in May. Activity then jumped to six transactions in June before slowing to two in July and one in August.

Half of the six-month transactions occurred off-market, demonstrating that a meaningful portion of G650ER activity continues to take place outside publicly advertised inventory.

Key Takeaways

  • Eight aircraft are currently available, representing only 1.8% of the fleet.
  • For-sale inventory has more than doubled since March.
  • Fourteen aircraft sold during the past six months, seven of them off-market.
  • Current asking prices range from $45.75 million to $55.0 million.
  • Current inventory averages 70 DOM versus 88 days for recently sold aircraft.
  • Sales peaked at six transactions in June before declining to two in July and one in August.

Key Insight

The G650ER market is beginning to offer buyers more choice without yet showing signs of excessive supply. Inventory has risen consistently, but availability remains below 2% of the fleet and current listings are relatively fresh at an average of 70 days on market. At the same time, the slowdown from six June transactions to just one in August is worth watching. If inventory continues climbing while monthly sales remain subdued, buyers could gain additional leverage heading into the fall. For now, however, the combination of low fleet availability, relatively short market exposure and meaningful off-market activity continues to support a competitive market for well-positioned G650ERs.
