If 4 countries are co-hosting the tournament, does all of them get automatic qualification? For the 2026 FIFA World Cup, all the three hosts (United States, Canada and Mexico) have been granted automatic entry, which has been criticized by a lot of people. But this will be even more tricky. If they grant automatic entry for a total of 4 teams, then it will reduce the importance of qualifying tournament. IMO, only one host should be given this right, and others should earn their place through participating in the qualifying tournament.
In my opinion, the host countries should automatically be qualified, without any exceptions, even if there are 4 host countries.
Just an observation, FIFA is reluctant to make the world cup with 4 countries, I don't know if this can be the tie-breaking factor for a possible choice.
If there is a World Cup in a country and this country does not participate, you can imagine that there will not be so much appeal to the inhabitants of that country, disfiguring one of the main purposes of the competition which is to promote soccer in these places. Other things like sponsorship, support and interest would suffer greatly.
So at this point I support automatic qualification yes, after all the country in question has a huge job to do to host a cup, and deserves the spot.
Despite being 4 countries, they are very close to each other in South America, making transportation and logistics much easier, unlike in 2026 where there are 3 countries of continental proportions.
You must also remember that automatic slots are counted and subtracted from the traditional slots of each federation.
In the next World Cup, CONCACAF will have 3 direct and one contested spot.
About this:
then it will reduce the importance of qualifying tournament
I think that the ones who suffer the most from this issue are the qualified teams themselves, since they will not participate in a championship worth qualifying at a high level.
The only thing left to do is to play friendly matches, against weaker teams in general, and this can harm the 4-year project that the teams are doing.
