A development driver for CGR since May 2022, Simpson spent the past two years competing in Indy NXT. This year, he earned two podiums - including a career-best runner-up result at Mid-Ohio and one pole en route to 10th in the championship standings.
The Cayman Islands native has also been racing the Asia Le Mans Series and European Le Mans Series, both with Algarve Pro Racing.
In the former, he has scored an overall win at the 4 Hours of Dubai and the LMP2 championship, while his ELMS campaign has delivered a notable victory in the 4 Hours of Le Castellet.
Further success has come with Tower Motorsports in IMSA’s endurance rounds, where he captured sports car victories at the Twelve Hours of Sebring race with the LMP2 class victory.
Simpson received his first taste of driving an Indy car earlier this year in January at Sebring International Raceway, as well.
“It’s been incredible working with Chip Ganassi Racing as their development driver over the last couple of years and I’ve been able to learn so much," said Simpson.
"I am very excited to be making the next step to IndyCar with this team. I had a great time at the test and I can’t wait to get back in the car. It’s been my dream to race in the NTT IndyCar Series and it’s an honor to make it happen now with one of the best teams in the series.
