Everton has secured their position for the next season of EPL by winning the last match. I think Stake will keep their sponsorship deal until the end of 2025-26 season of EPL with Everton if they don't get demoted to EFL championship. Because, gambling site sponsorship (on front of shirts) has been
banned by Premier League clubs from 2026-27 season.
I thought it comes from mandatory regulation but in the article, it is voluntary agreement to ban gambling site advertisement on skirts. That will affect income of Premier League as gambling sites can give them very good sponsor offers.
I don't know that this change is related to appearance of Bitcoin and cryptocurrency on those club skirts. I believe it is not because the article only says about gambling sites, not mention about gambling sites that accept Bitcoin and cryptocurrency. Hope that it will be changed in future and gambling sites will be able to advertise their business in Premier League and help to expose Bitcoin to more people.
