With the, it leads to the question -- who else might bid?
First, it’s important to note that due to rules, any country can bid to host the cup as long as their continental confederation hasn’t hosted either the past two World Cups. With the 2018 World Cup in Russia and the 2022 World Cup in Qatar, Europe and Asia are excluded. And considering that Africa had it in 2010 with South Africa hosting and the 2014 World Cup was in South America (Brazil), the USA, Canada, Mexico bid is the heavy, heavy favorite.
But, there will be other bids. Here are the ones that seem likely.
The South American nation is hungry to host the cup after winning the bid in 1986 but seeing it moved to Mexico due to economic reasons. Politicians are already talking about it in that country, and this seems like the biggest threat to the North American bid, though it seems unlikely.
Morocco is rumored to be interested, and when isn’t it? It has submitted bids for every World Cup from 1994 to 2010, except for the 2002 cup. Expect another bid here.
When will we know?
A decision is set to be made in.
