However, the organisation pushed back against the proposed entry, questioning the value an 11th team would bring to the series, ultimately rejecting Andretti's request overall to be part of the 2026 lineup.
Despite this, the motorsport giant have gone on to ramp up preparations for a spot on the grid, opening up a Silverstone-based headquarters in the UK and hiring F1 legend Pat Symonds to their ranks.
There has been much debate about Andretti Global potentially joining F1 in a different capacity, for example by potentially buying into a team that already occupies one of the 10 spots on the grid.
Led by former F1 racer Michael Andretti, the team already compete in IndyCar, Formula E and Australian Supercars series.
Now, Andretti's father, 1978 F1 world champion Mario Andretti, has opened up on the latest developments within the organisation.
Speaking with Gazzetta Dello Sport, he suggested that there could be news of an update to their entry bid on the way.
"This is a topic that has my son Michael and his company as the protagonist, not me," he said.
"What I can say is that there will be news and changes and that my full support goes to my son for all the decisions and choices he has made during this period and will make in the future to best manage the situation."
