The Premier League side will leave the Boleyn Ground at the end of the season.
The Hammers are due to leave the Boleyn Ground at the end of the current campaign, having signed a 99-year tenancy at the 54,000-seater stadium (via Sky Sports).
And Gold explained that based on the demand for tickets that they have had so far, he feels very confident that they should not have any problem making the step up from Upton Park, which boasts just over 35,000 seats.
"Certainly over 30,000 tickets have already been sold. We expect to sell all the season tickets," he told Sky Sports.
"Everybody has believed that 35,000 at Upton Park that you are going to have empty seats with 54,000 seats at the Olympic Stadium. Well, we are going to sell those 54,000 [seats] and sadly there are going to be some disappointed fans."
As difficult as it will be for West Ham to say goodbye to the ground that they have called home for well over a century, the move to Stratford should signal an exciting time for the club.
The improved facilities may well help Slaven Bilic persuade top players to join them, rather than perhaps consider a move to another of their Premier League rivals.
Given the progression that they have made in the past two seasons - they currently sit sixth in the table despite losing several important players to injury throughout the campaign - the move to the Olympic Stadium should only help the club make that next step that would perhaps see them challenging for a spot in the top four.
