Prediction market Kalshi has removed promotional markers from social media platform X after a policy shift tightened oversight of gambling-related advertising.
Kalshi confirmed it had stripped affiliate badges from X profiles tied to revenue-sharing arrangements promoting its event contracts, according to The Block.
The move followed updated paid partnership rules introduced last week by X, which aim to limit undisclosed gambling and sports-betting promotions.
“Add a follow-up reply disclosing that this is a paid promotion for Kalshi. Otherwise, this will result in a suspension,” Nikita Bier, Head of Product at X, wrote in response to one affiliated account.
