It looks a long partnership between Sportsbet.io and Newcastle United but this can potentially be affected by policy changes in England. Their government have been considering possible strategic national changes entirely in sports and gambling marketing and advertisements, so they might let it be like now or tighten it more in upcoming years.
It may worth mentioning that the changes will go into effect in 2026/27 season and they will not affect the coming season.
From theguardian.com:
Premier League clubs ban gambling sponsors on front of shirts from 2026-27Correct ^^
And also remember, we were not front of shirt, or on any part of the shirt to be fair.
People can say what they want about sportsbetting and gambling, but a lot of clubs now have to look elsewhere for sponsorship funds... Its going to be a interesting few years in this space!
