The killing of Iran’s Supreme Leader over the weekend not only triggered global political shockwaves but also created massive activity on online prediction markets.
Millions of dollars were wagered on platforms like Kalshi and Polymarket as users tried to predict the outcome of military strikes and leadership changes. However, confusion over market rules and contract wording has now led to public backlash.
Millions Bet on Khamenei’s Death and Iran Strikes
After US and Israeli forces reportedly killed Ali Khamenei, online prediction markets saw huge trading activity.
On Polymarket, users placed at least $200 million across four main wagers linked to US strikes, regime change, and Khamenei’s death. Meanwhile, Kalshi recorded nearly $55 million in contracts related to whether Khamenei would be “out” within the next few months.
Market-surveillance company Bubblemaps reported that several crypto wallets connected to Polymarket made over $1.2 million in bets related to the Iran strikes.
Here’s a quick overview:
| Platform | Amount Wagered | Focus of Bets |
|---|---|---|
| Polymarket | $200+ million | Strikes, regime change, death |
| Kalshi | $55 million | Whether Khamenei would be “out” |
| Crypto Wallet Activity | $1.2 million | Strike-related wagers |
Confusion Over Market Rules
As news about the strikes unfolded, many users complained about how their bets were handled.
Kalshi eventually halted activity on certain markets. Co-founder Tarek Mansour later announced that bets would be settled based on their value just before the military action was confirmed. Users who purchased contracts after that point would receive partial reimbursement.
Kalshi stated that it does not allow markets directly tied to death and claimed that precautions were taken to prevent trading based on assassination outcomes. The company also reimbursed certain fees and net losses, saying the user experience could have been clearer.
On Polymarket, one market asked whether the US would “forcibly remove” Khamenei by March 31. It later resolved to “no,” with clarification that the US had only “contributed to or assisted” in his killing. Some users questioned this interpretation and demanded disputes.
Ethical and Legal Concerns Raised
Markets involving death or violent events are highly controversial. Critics argue they could create financial incentives linked to harm.
In February, six Democratic senators urged the Commodity Futures Trading Commission to investigate contracts that may “incentivize physical injury or death.” Senator Chris Murphy also announced plans to introduce legislation aimed at preventing people from profiting from war-related events.
Prediction markets in Israel have also come under scrutiny. Earlier this year, authorities reportedly arrested several individuals accused of using military secrets to place bets on Polymarket.
Mixed Reactions From Users
While some users accused platforms of being unfair or “rigged,” others defended the companies.
One Kalshi user complained about losing money on a bet regarding Khamenei’s removal, calling the platform unreliable. However, other users argued that traders should carefully read contract rules before investing money.
Polymarket, which operates on blockchain technology, uses a decentralised resolution system for many markets. As of Sunday morning, it reportedly had 187 Iran-related markets open, though many had low trading volumes.
A New Era of War and Wagering
The events surrounding the strikes on Iran highlight how quickly global conflicts now intersect with digital finance platforms. What was once limited to traditional news coverage has now expanded into real-time betting markets where users speculate on geopolitical outcomes.
However, the controversy shows that when real-world violence and financial speculation overlap, ethical and regulatory questions quickly follow. Governments and regulators are likely to increase scrutiny over how prediction markets operate, especially when contracts involve war, political instability, or loss of life.
As tensions in the Middle East continue, the debate over whether such markets should exist — and how they should be regulated — is expected to grow stronger. For now, both platforms face pressure to improve transparency, clarify rules, and address concerns about fairness and moral responsibility.
