Kalshi Users Lose Money on Ethically Canceled Bet

Kalshi, a prediction market platform, has faced backlash after canceling a bet tied to the potential death of Iran's Supreme Leader Ali Khamenei. CEO Tarek Mansour announced that users would be refunded, but many claim they have incurred losses.

The suspension of trading followed rumors regarding Khamenei's death, which had been a subject of betting since November 2025. Mansour clarified on X that the platform does not allow markets directly linked to death, emphasizing their commitment to ethical practices in trading.

"We don’t list markets directly tied to death. When there are markets where potential outcomes involve death, we design the rules to prevent people from profiting from death," Mansour stated.

He acknowledged the significance of markets related to political changes, like Khamenei's potential resignation, and expressed a need for better communication of the platform's rules to enhance user experience. Despite assurances that no user would lose money, many users reported discrepancies in compensation, sparking outrage on social media.

One user, identified as Sameer, shared a screenshot revealing a winning position that would have yielded over $12,000, but instead resulted in a mere $245 compensation. Others echoed similar grievances, claiming they were misled about their potential earnings.

"Deceiving your customers and then lying on social media will be fun in court," Sameer remarked.

As frustration grew, some users urged regulatory bodies like the SEC and CFTC to investigate the situation, citing unclear cancellation terms at the time the market was created. Meanwhile, the day of the rumored strike on Iran saw a record trading volume of $478 million on Polymarket, with $220 million attributed to political bets.

In light of the controversy, Ethereum co-founder Vitalik Buterin expressed concerns about the integrity of prediction markets, warning against the increasing influence of uninformed speculators in the sector.
