Through the partnership, the operator will advertise its DFS products in the Colts’ stadium, along with digital, radio and TV advertisements during games.
The deal will last throughout the 2019/20 season.
Matt King, FanDuel CEO, said: "As we continue to expand our nationwide footprint, we are always looking for ways to engage sports fans throughout the country and specifically in the Midwest.
"Indianapolis is home to a loyal fan base and we’re excited to again partner with the Colts organisation, allowing us to further reach these passionate fans."
Roger VanDerSnick, Colts Chief Sales and Marketing Officer, said: "The Colts always are looking for new ways to engage with our fans and fantasy sports have long been an avenue for fans to follow the Colts, pro football and their favourite players across the league.
"We’re very pleased to come together with FanDuel to make our fan experience the best it can be during the season and year round."
Last month, DraftKings became the NFL’s first official DFS partner, giving the operator access to league branding for its DFS products.
