TikTok has announced a new, multi-year partnership with Major League Soccer (MLS), which will see MLS share exclusive content and in-app programming, while also incorporating in-stadium activations and TikTok sponsorship of various MLS events and tournaments.
According to TikTok:

“As an ‘Official Partner’ of MLS, TikTok will be integrated into every MLS game throughout the season through various in-stadium branding, TikTok & MLS content across stadium videoboards, and more. TikTok is also the co-presenting sponsor of eMLS Cup, the League’s esports tournament. We’re excited to continue spotlighting TikTok as a place where the sports and gaming community intersect, while providing quality entertainment for all.”

Another source where TikTok will be integrated further with the major sporting leagues to gain more fan following on the app.
There are also new opportunities created for the creators.

"Over the course of the partnership, TikTok and MLS will launch a new Club Creator Network, where TikTok creators will be paired with MLS Clubs to create exciting content during the regular season and off-season. Creators and MLS Clubs will work together to enhance the fan experience by offering unique access to their favorite MLS players and behind-the-scenes moments that can only be found on TikTok."

The agreement will provide TikTok users with the ability to access MLS content and clips. This would give fans more avenues to create their own MLS highlight videos as well as integrations which would further provide promotion for the league.

"Throughout the season, fans can also search 'MLS' on TikTok and get access to the MLS Hub, featuring the newest content from MLS, its Clubs, and players - all in one place. From the Hub, fans can also access MLS's website with more information about match schedules and scores."

This one is, of course the most popular on all other platforms, but soccer content - such as views on the #soccer tag - has gained more than 500 percent over the past two years. That, of course would be somewhat influenced by the World Cup and broader engagement with that event-but even so, there's a growing legion of soccer fans within the app who will keenly consume more content.

In fact, as of now, the @mls TikTok account has garnered more than 1.2 million followers.
Therefore, it is time for TikTok to fully formalize their partnership so that it can deepen its entrenchment in as many ways as possible to avoid having a US ban.

I mean, that probably won't factor into any decision on such, but maybe, if TikTok can show that it's a critical information channel, in a range of ways, that could help to strengthen its case.

Either way, more soccer content can only be beneficial, while the expanded sponsorship elements will bring even more exposure for the app.
