Not only have record numbers of supporters stumped up their hard earned cash nearly a year ahead of the move, there are still nine months to go with demand outstripping supply.
Demand outstripping supply
"West Ham United are delighted to announce that they have already sold more season tickets for their first season in the former Olympic Stadium than in any other year in the club’s history, despite there still being nine months to go until their first game," said a statement on whufc.com.
"The Hammers passed the milestone last month, and, with the iconic venue winning plaudits the world over during the Rugby World Cup and Slaven Bilic bringing entertaining football back to E13, demand for tickets to see West Ham in Stratford in the 2016/17 season continues to surpass all expectations."
The club also revealed there are now several times as many fans on a priority waiting list as there are remaining season tickets.
The East Londoners currently have over 20,000 season ticket holders and the most they have sold in one season is 26,000.
When they move there will also be the option to increase the Olympic Stadium capacity to 66,000 in the future.
And judging by the announcement, the Hammers may well need to.
"At the moment we have 20,000 season tickets approximately and we're moving to 35,000 and hoping to get to 40,000 season tickets.
"Hospitality is doubling from 2,000 to 4,000 and we're sold out in all but one lounge so we're very pleased."
Humble pie for cynics
When away tickets, which will average at around 4-5,000 allocation per game, are taken into consideration, it means West Ham will have less than 9,000 tickets for any given match day.
The figures make a mockery of ill-informed predictions from pundits, rival fans from the likes of Tottenham Hotspur, Chelsea and Arsenal and even some of their own supporters that the Hammers would struggle to fill their new home.
And it also begs the question of when and not if the Hammers bump it up to 66,000 to increase revenue and grow the club even further.
