The competition will reduce to 10 events from next season, with five in the United States and five held around the world.
There were 14 events planned for the 2026 season but in April, LIV postponed June’s New Orleans competition amid questions over its future and has not announced a rescheduled date.
O’Neil said LIV is focused on “delivering a great week for fans and players at Bedminster” in New York, starting on Sunday and “finishing the 2026 season strong” – but made no explicit mention of the final two events scheduled this season, in Indianapolis from 23 August and the concluding team championship in Michigan from 30 August.
Major winners including Bryson DeChambeau, Dustin Johnson, Jon Rahm, Cameron Smith, Martin Kaymer and Sergio Garcia remain part of the LIV roster after having left the PGA Tour.
American major champions Brooks Koepka and Patrick Reed rejoined the PGA Tour after it introduced a returning member programme.
In July, the PGA Tour and DP World Tour struck an alliance with the Asian Tour in another blow to LIV Golf.
O’Neil added: “We’re also seeing strong interest from more than a dozen additional parties to potentially serve as minority investors, creating a multi-partner model built for long-term stability and growth.”
LIV was founded in 2021 and launched the following year with 54-hole events and took its name from the Roman numeral for 54.
However, it moved to the traditional 72-hole format for golf tournaments from this season.
