Florida-born Koepka, who is married and has a young son, turned professional in 2012 and won nine PGA Tour events during his nine seasons on North America’s elite professional circuit.
The PGA Tour also wished Koepka and “his family continued success” in a statement, before adding they “continue to offer the best professional golfers the most competitive, challenging and lucrative environment in which to pursue greatness”.
A three-time US PGA champion, Koepka, has also twice triumphed at the US Open.
His defection from the PGA Tour, along with big names such as Phil Mickelson, Dustin Johnson and Bryson DeChambeau, was seen as a major coup for LIV during a period when the sport appeared to be at civil war.
Koepka’s captaincy of the LIV Golf team, Smash, will now pass to Talor Gooch, with the side having an opening to fill for the start of the 2026 season in February.
Koepka becomes the first star player to leave LIV Golf, however, there has been speculation over his future for months and a possible return to the PGA Tour.
The Tour has suspended players who competed in LIV Golf events after categorising them as unauthorised. Non-members have been subject to a year ban following their previous LIV event.
Koepka will also be eligible to join the DP World Tour and have exemptions to compete in golf’s four major championships.
Earlier this week, Chilean Mito Pereira announced his retirement from golf aged 30 after three seasons with LIV.
