The twice major champion's participation in Ireland was in jeopardy after he was not included in a group of eight LIV Golf players given conditional release by the DP World Tour in February.
"The DP World Tour and Jon Rahm have come to an agreement on conditional releases to play in conflicting tournaments on LIV Golf during the remainder of its 2026 season," a DP World Tour spokesperson said.
"This involves payment of all outstanding fines accrued from 2024 to date, along with participation in agreed DP World Tour tournaments (outside the Majors) in the remainder of the 2026 season."
Rahm had accused the DP World Tour in March of "extorting players" after refusing to agree a deal allowing LIV Golf players to compete in tournaments on both Tours.
The settlement required Rahm to pay outstanding fines of reportedly around 2.5 million pounds ($3.33 million) for playing LIV events without permission, withdraw all pending appeals and commit to playing stipulated DP World Tour tournaments.
On Tuesday, the former world number one said there was no longer a stand-off between himself and the DP World Tour.
"We were able to reach an agreement. There was some concessions on both sides. I offered some; they extended an olive branch. Obviously we've reached an agreement. That will not be a stress anymore," he told reporters ahead of the LIV Golf event in Washington DC this week.
"The Ryder Cup is still really, really far away, but I'm happy that hopefully I won't have to think about any worries or any predicaments come to Adare Manor then or hopefully ever.
"I want to support the DP World Tour. There's a lot of events I want to play."
Tyrrell Hatton, Laurie Canter, Thomas Detry, Tom McKibbin, Adrian Meronk, Victor Perez, David Puig and Elvis Smylie were all previously given dispensation to play on both Tours after reaching individual agreements with the DP World Tour.
Rahm will now be eligible to earn Race to Dubai ranking points at next week's PGA Championship and at subsequent Race to Dubai counting events he participates in during the 2026 season.
The 2027 Ryder Cup will be held at Adare Manor from September 17-19.
