Kalshi, a CFTC-regulated prediction market platform, recently faced backlash after settling its “Will Ali Khamenei be out as Supreme Leader?” market at the last traded price before his death, rather than paying out “Yes” bets fully. Traders who bet on Khamenei’s removal—confirmed via U.S. and Israeli strikes—accused the platform of unclear rules and unfair practices, sparking calls for lawsuits. This article examines the controversy and potential legal claims under New York law, assuming a suit by affected New York users.
Event Background
Ayatollah Ali Khamenei, Iran’s Supreme Leader, died in late February 2026 from strikes, triggering Kalshi’s market resolution. The contract drew significant volume, with users buying “Yes” shares expecting payout if he exited power by a set date. Kalshi invoked a “death carve-out,” halting trades and settling at pre-death prices, refunding fees but denying full wins to many.
CEO Tarek Mansour defended this publicly, stating Kalshi avoids markets profiting directly from death per U.S. rules, reimbursing post-death buyers. Critics argued the clause was buried, added late, or ambiguous. No formal lawsuit has emerged yet, but threats abound amid high trading volume.
Kalshi’s Contract Rules
Kalshi’s Rulebook includes provisions allowing settlement at last traded price for unresolvable outcomes. The Khamenei market noted that if Ali Khamenei passed away, the market would settle using the last traded price before the death. Users claim this was grammatically unclear or not visible pre-bet.
The Member Agreement mandates arbitration for disputes, limits liability, and caps damages. It emphasizes CFTC compliance, prohibiting death-direct settlements. New York AG warnings highlight prediction markets’ lack of consumer safeguards.
Breach of Contract Analysis
New York common law governs such claims, requiring: (1) valid contract; (2) plaintiff’s performance; (3) defendant’s breach; (4) damages. Kalshi’s Terms form the contract; users performed by funding bets compliantly.
Breach could arise if terms were ambiguous or unconscionable. Courts interpret against drafters (contra proferentem), potentially voiding hidden clauses. Material breach—failing core payout purpose—might allow termination and full damages. Expectation damages would compensate lost profits, e.g., $1 per “Yes” share minus settlement.
Arbitration clause may bar court, but challenges for unconscionability exist under FAA scrutiny in New York.
New York Statutory Claims
General Business Law § 349: Prohibits deceptive acts; prediction markets’ opacity could qualify, allowing actual damages, injunctive relief, and attorney fees. NY AG alerts highlight risks, bolstering claims.
FAIR Business Practices Act (2025): Expands to “unfair/abusive” practices beyond deception, covering businesses—not just consumers. Unclear death carve-outs might be “unfair,” enabling AG or private suits.
Contract Remedies: N.Y. CPLR Article 30 supports discovery for trade data proving losses. Class actions viable if common issues predominate, given uniform terms.
| Claim Type | Key Statute/Rule | Potential Remedy | Challenges |
| Breach of Contract | NY Common Law | Expectation Damages | Arbitration Clause |
| Deceptive Practices | GBL § 349 | Actual Damages + Fees | Must Prove Reliance |
| Unfair Practices | FAIR Act | Injunction + Restitution | Novel Application |
Litigation Outlook
A New York suit might file in Supreme Court (e.g., Manhattan), seeking to compel payout or declare terms unenforceable. CFTC oversight defends Kalshi federally, but state contract law applies privately. Precedents show federal preemption fights, but user claims differ.
Class certification hurdles: individualized reliance vs. uniform deception. Arbitration likely funnels to AAA, limiting discovery. Success odds low if clause upheld, but publicity pressure may force settlements.
Plaintiffs must prove notice inadequacy—e.g., via screenshots showing buried rules. Kalshi’s late webpage updates weaken defenses.
Strategic Advice for Traders
Document all bets, emails, and rule views pre-settlement. Consult counsel for demand letters citing GBL § 349. Monitor AG actions; collective arbitration possible. Platforms like Polymarket resolved similarly without revolt, highlighting Kalshi’s phrasing issues.
This saga underscores prediction markets’ legal tightrope: innovation vs. clarity. Traders: read fine print; platforms: bold caveats. Future CFTC rules may standardize death carve-outs.
Frequently Asked Questions (FAQs)
What exactly happened with Kalshi and the Khamenei market?
Kalshi settled the market at the last traded price before Khamenei’s death, citing a “death carve-out” rule, instead of paying full “Yes” winnings to bettors who expected payout upon his removal from power.
Can affected traders sue Kalshi in New York?
Yes, New York users could pursue breach of contract or deceptive practices claims under GBL § 349, though Kalshi’s arbitration clause may force disputes into private resolution rather than court.
What defenses does Kalshi have?
Kalshi relies on its Member Agreement and Rulebook, which explicitly address death-related settlements to comply with CFTC regulations, plus mandatory arbitration to limit class actions.
Is this a class action opportunity?
Potentially, if plaintiffs show uniform deception across users, but challenges include proving reliance and overcoming arbitration requirements under New York law.
What remedies might successful plaintiffs win?
Expectation damages (full payout value), attorney fees under GBL § 349, or injunctions under the FAIR Act, depending on the claim and whether arbitration allows such awards.
Should traders demand payment now?
Yes—send a formal demand letter citing specific rules and statutes, preserve evidence like screenshots, and consider group action through arbitration for leverage.
