Background and career
Jared Taylor Isaacman (born February 11, 1983) is an American billionaire entrepreneur, pilot, and commercial astronaut who has served as the 15th administrator of NASA since December 2025. He founded the payment processor Shift4 Payments, which he led as chief executive until 2025, and co-founded Draken International, which provides adversary training to the U.S., British, and other NATO air forces. Forbes estimated his net worth at US$1.5 billion as of April 2025. Isaacman commanded Inspiration4 – the first all-civilian spaceflight – using SpaceX's Crew Dragon Resilience, which launched from Kennedy Space Center on September 15, 2021. He later led Polaris Dawn, during which he became the first private citizen to perform a spacewalk. In December 2024, President Donald Trump nominated him to serve as the 15th administrator of NASA. During his April 2025 confirmation hearing, Isaacman emphasized his outsider status and entrepreneurial background, stating his intent to usher in a "new Golden Age of Science and Discovery" at the agency. He faced questions over his close ties to Elon Musk, the founder of SpaceX, one of NASA's largest contractors. On May 31, 2025, Trump, among several actions preceding his feud with Elon Musk, withdrew Isaacman's nomination to serve as NASA administrator. He was renominated on November 4, 2025. He was confirmed as NASA administrator by the Senate on December 17, 2025 and sworn in the following day. As administrator, he has overseen a restructuring of the Artemis program that made Artemis III a 2027 test flight in Earth orbit ahead of a first crewed landing on Artemis IV in 2028, and the crewed lunar flyby of Artemis II in April 2026.
Isaacman was born on February 11, 1983, at Overlook Hospital in Summit, New Jersey, to Donald and Sandra Marie Isaacman. He is the youngest of four children and is of Jewish descent. His family lived in Union Township before moving to Westfield, New Jersey, around 1987, and later to the Liberty Corner section of Bernards Township when he was 12. He attended Wilson Elementary School in Westfield and William Annin Middle School in Bernards Township. While a student at Ridge High School, he launched a computer services business with a friend. At age 16, he left school to work full-time, later earning a GED. He received a bachelor's degree with a major in professional aeronautics from the fully online Embry–Riddle Aeronautical University Worldwide Campus in 2011.
In 1999, Isaacman founded United Bank Card, later renamed Harbortouch and then Shift4 Payments, a point-of-sale payments company, and served as its chief executive officer from its founding until 2025. By 2015, the company was generating $300 million in revenue and processing $11 billion annually. By 2020, it had scaled to $200 billion in payments per year. In the same year, Isaacman took Shift4 public and began processing payments for SpaceX's satellite-internet business, Starlink. Shift4 expanded internationally through acquisitions, including the cross-border e-commerce payments firm Finaro, announced in March 2022 for $525 million and completed in October 2023, and the tax-free shopping and payments company Global Blue, completed in July 2025. Effective June 5, 2025, Isaacman stepped down as CEO and became executive chairman, and the company's president, Taylor Lauber, succeeded him as CEO. Upon his Senate confirmation as NASA administrator in December 2025, Isaacman resigned as executive chairman and as a director, and Lauber became chairman. Under his agreement with the Office of Government Ethics, Isaacman agreed to vote only about 25% of the company's voting power and was not required to divest his stake. In February 2026, a restructuring collapsed Shift4's multi-class share structure into a single class of common stock and ended Isaacman's rights under a tax receivable agreement, ending the company's status as a "controlled company" under New York Stock Exchange rules; Isaacman remained its largest shareholder, with about 25.9% ownership. In 2011, Isaacman co-founded Draken International, a defense aerospace company based in Lakeland, Florida, that grew out of his Black Diamond Jet Team and operates one of the world’s largest fleets of privately owned fighter jets. The company provides adversary training to U.S. military pilots and manages hundreds of millions in defense contracts. In 2019, Isaacman sold a majority stake in Draken to Blackstone.
Isaacman has logged more than 8,000 flight hours and has flown in more than 100 airshows. He co-founded the Black Diamond Jet Team in 2010, which performs at airshows. He made two attempts to break the world record for circumnavigating the globe in a light jet, achieving the record in 2009 with a time of 61 hours, 51 minutes, and 15 seconds—about 20 hours faster than the previous record. He received the call sign "Rook" during fighter jet training. Isaacman is flight-qualified in multiple military jet aircraft including the A-4, Alpha Jet, F-5, L-39, L-159, MB-339, MiG-29UB, T-33, and T-38, and holds civilian jet type ratings for the CE-500, CE-510, CE-525 and CE-650 series of Cessna Citation business jets and the RA390 (Premier I).
In February 2021, Isaacman announced he would command Inspiration4, the first orbital mission with no professional astronauts aboard. Operated by SpaceX using the Crew Dragon spacecraft, it launched on September 15, 2021, and orbited Earth for three days. During the mission, Isaacman placed the first known sports bets from space. The flight raised over $250 million for St. Jude Children’s Research Hospital, a cause Isaacman championed throughout the mission.
In 2024, Isaacman led Polaris Dawn, the first mission in the privately funded Polaris Program. The four-person crew reached a peak altitude of 1,400 kilometres (870 mi), the farthest from Earth any human had gone since Apollo 17, before lowering to 700 km (430 mi). On September 12, Isaacman and crewmate Sarah Gillis performed the first private extravehicular activity (EVA), becoming the first civilians to conduct a spacewalk, technically a Stand-up EVA (SEVA) as at no point did either crew-member fully exit the spacecraft. Over the five-day flight, the crew conducted about 36 science experiments with 31 institutions and tested Starlink laser-based communications in orbit. In written answers to senators following his April 2025 confirmation hearing, Isaacman said he had terminated his contracts with SpaceX for future Polaris Program missions and had been refunded the advance payments he made for them.
