Prediction market Kalshi removed all its "Affiliate Badges" from the X platform due to recent tightening of rules regarding paid promotions related to sports betting content. These badges, previously visible identifiers of influencers and affiliate members who had contracts to promote events with Kalshi, indicated their official relationship with the platform, though not their employment status. Nikita Bier, X's product manager, had warned accounts that failing to disclose paid promotions with Kalshi would result in suspension. In one interaction, Bier requested an account to specify in a subsequent reply that it was a paid promotion for Kalshi, noting that undisclosed business relationships undermined user trust in the authenticity of the partnership. This policy change echoes X's previous regulatory actions against encrypted messaging platforms. However, while Kalshi removed its badges, its competitor Polymarket's affiliate program retained them.
