TikTok battles, also known as PKs or player knockouts, are a monetization feature within the TikTok platforms livestreaming function. Creators can initiate battles where they go head to head in 5-minute competitions to see who can get the most gifts, which are virtual stickers that viewers can purchase with real money. The battles can pull in six figures a month, and TikTok takes a percentage of the money from people buying coins and half of whatever creators are gifted.

To come out on top in TikTok battles, creators frequently resort to imploring, hyping up, and begging viewers to donate. Some talent-based streamers incorporate skills like dancing or rapping to earn gifts, but critics argue that battles now focus more on pleading than performance. Detractors label TikTok battles a "sham" for emphasizing begging over battling skills. Concerns also surround the lack of transparency around TikToks large commission percentages and how much streamers take home. Toxicity is also an issue as clashes between creators result in harassment.

Despite criticisms, battles satisfy viewers desires for accessibility, community, and "realness" compared to highly polished Instagram. Their popularity stems from accessible discovery of everyday micro-influencers rather than professional gamers on Twitch. As one of few monetization methods, battles provide income opportunities that drive their proliferation - though mostly benefiting TikTok rather than creators.
