Kalshi and Polymarket boost then retract LA election fraud influencer posts

Kalshi asked paid influencers to remove social media posts that promoted unsubstantiated claims of fraud in a Los Angeles mayoral election, after the platform and Polymarket had boosted the content through paid partnerships. Both platforms had enlisted influencers to drive interest in political markets, but the sponsored posts spread conspiracy-laden messaging about election integrity, according to multiple reports published the first week of June 2026. Kalshi subsequently barred its paid creators from questioning the accuracy or integrity of its markets, tightening affiliate rules following the crackdown on California election misinformation. Polymarket's response was not reported. The episode underscores how regulated and crypto-native prediction markets are policing compensated promoters around politically sensitive contracts.
