Main title sponsorship is defined by the first brand name in the official name (according to UCI).

This question would resolve in yes, if the name was a brand or a Joint Venture of Ineos, if Ineos changed names or merged.

This question won't be effected by change of team status (i. e. World Tour/Continental).

This question is about the current team named Ineos Grenadiers (former Ineos, Sky) and won't be effected by other or new teams.

I. e. Ineos Soudal, Team Grenadiers Ineos, The Grenadiers Soudal -> Yes

Soudal Ineos, Soudal Grenadiers, RedBull -> No

This question will be solved on January 1st 2027 or whenever another team main sponsor officially appears.
