Retired from active racing, he is now chairman and CEO of Andretti Global, a team that has won four INDYCAR® Series championships and five Indianapolis 500 races.

Two years after his father, legendary race car driver Mario Andretti, clinched the 1978 F1 World Championship, Michael began his own racing career. He initially competed in Formula Ford and claimed victory in the 1982 SCCA Super Vee Championship with a Ralt RT5. Afterward, he raced in Formula Atlantic in 1983 and had his debut at Le Mans in the same year, finishing third in that race. Michael was named Co-Rookie of the Year in the 1984 Indianapolis 500 and finished as championship runner-up in 1986. In 1991, he had a banner year, finishing second in the Indianapolis 500 before winning the Champ Car World Series. Michael has also raced as part of McLaren’s Formula One team.

After racing in the 2003 Indianapolis 500, he retired from full-time INDYCAR racing and bought into “Team Green” which became Andretti Green Racing. In 2009, Andretti Green Racing restructured and emerged as Andretti Autosport, with Michael as sole owner. Across those years, the team won the INDYCAR title on multiple occasions with Tony Kanaan in 2004, Dan Wheldon in 2005, Dario Franchitti in 2007 and Ryan Hunter-Reay in 2012.

Andretti Autosport has now become Andretti Global, a global racing institution born out of racing excellence. The team fields multiple entries in the NTT INDYCAR SERIES, Indy NXT Presented by Firestone and IMSA. Additionally, Andretti Global operates in the ABB FIA Formula E Championship, competing in the world’s first race series for fully-electric Formula cars and claiming the Drivers World Championship in 2023. The team also races in Extreme E as Andretti Altawkilat Extreme E, helping to further develop sustainability in racing. Overall, Andretti Global boasts a highly impressive track record of over 260 total race wins, four INDYCAR SERIES championships, three INDY NXT titles, one Indy Pro 2000 and one USF2000 championship, alongside five Indy 500 victories. In 2018, Michael began a collaboration with Ryan Walkinshaw’s Walkinshaw Racing and Zak Brown’s United Autosports to create Walkinshaw Andretti United.
