Mark Cuban’s Gulfstream V
Cuban bought his $40 million Gulfstream V by email in October 1999 without seeing it, which Guinness World Records logged as the largest e-commerce transaction ever. He later added a Gulfstream G550 and a Boeing 757 configured for the Dallas Mavericks, plus a 767 offered for charter.

Elon Musk
Gulfstream G650ER · $70M reported
The tail number encodes his 28 June birthday, and the G650ER became the most-tracked business jet in the world after a student-run account began posting its movements in 2020. Musk also operates two Gulfstream G550s and was reported to have ordered a G700 in 2022. The jet's public tracking led to a 2022 policy change on Twitter/X that banned real-time location sharing.

Jeff Bezos
Gulfstream G650ER · $65M reported
Bezos has owned two G650ERs through a Seattle holding company and was reported in late 2024 to be selling the older one (a 2015 airframe) for just under $39 million after taking delivery of a new Gulfstream G700 reported at around $80 million. His arrival at the COP26 climate summit by Gulfstream drew wide media attention in 2021.

Bill Gates
Gulfstream G650ER (two) · $70M reported
Gates is reported to own two G650ERs, both 2018 builds based at Boeing Field in Seattle, plus access to Challenger 350s via a NetJets arrangement. He has called private flying his 'guilty pleasure' and says he offsets his emissions by funding direct-air-capture and sustainable fuel ventures.
