The Spaniard is not guaranteed a place in Europe's team after defecting to LIV Golf in 2023 and explained that, while captain Luke Donald has been in touch, he is not assured of a spot against the USA at Bethpage Black in September.
Rahm said of the latest LIV event in Chicago: "There's nothing I can confirm nor deny. He [Donald] has been texting me like he has been texting quite a few other players that are on that list of the possibility of getting picked.
"Luke is extremely dedicated and very well organised as a captain - six automatic and then six picks, right - so there's probably about at least 10 names on top of those guys who are qualified that he's probably constantly texting.
"I don't think he's actually told anybody they're in yet because it's too early. He's probably waiting until the end of August through the [PGA Tour] Playoffs and our events to maybe start making statements like that.
"In my case, I think I'm just one more of those many names."
Rahm is hopeful that adjustments can be made to the LIV Tour to ensure that the players get ranking points beyond the year's four major championships.
He said: "There's a process to hopefully entering those world ranking points and at least get our foot in the door. Once we're allowed, we can see what changes can be made to earn as many as possible, keeping the integrity of what LIV Golf is about.
"Examples of that would be, let's say with whatever we're doing currently we get 20 points. If you add a fourth round, you go to 25. Is that worth it, is that not worth it?
"Right now with as little players as we have, I don't see a cut working very well, and with the teams [format] I think it would be a little odd.
"But if the league were to expand and let's say you go to 15 teams, you have 60 players, now you can actually possibly make something work.
"There's many possibilities that I can think of; this is completely hypothetical because I haven't spoken to anybody about it, but there's things we could do I think to add more world rankings points if we need it."
