In December 2014 it was announced Carter would be joining Parisian club Racing Metro after the 2015 Rugby World Cup, on a three-year deal worth a reported €1,500,000 a season, making him the world's highest paid rugby player. In November 2015 Carter revealed that, while recovering from an Achilles tendon tear in 2013, he met with Robert Kraft, the owner of the New England Patriots of the National Football League about possibly joining the team as a kicker. On 24 June 2016, Carter helped Racing Metro win the 2016 Top 14 final with a 29-21 win against Toulon at Camp Nou, Barcelona scoring 15 points (5 penalties) and was named Man of the Match despite being down to 14 men 18 minutes into the game after teammate Maxime Machenaud got sent off for a dangerous tackle on Australian international Matt Giteau.
