Prediction Markets War Betting: How Iran Trades Sparked Insider Trading Fears and the Death Carveout Scandal

In the hours before US and Israeli forces struck Iran on February 28, 2026, traders on prediction marketsFinancial markets where participants wager on the probability of future events, with contract prices reflecting the market's implied likelihood of outcomes. placed war-related bets that collectively suggest some of them knew what was coming. One account, trading under the name “Magamyman,” wagered on the death of Iran’s Supreme Leader Ayatollah Ali Khamenei shortly before news of the strike broke publicly, according to NPR. The account made more than $553,000 in profit.

That trade was not an isolated event. Blockchain analyticsThe examination of blockchain transactions and wallet patterns to identify suspicious activity, fund flows, and potential market manipulation. firm Bubblemaps identified six wallets on Polymarket that collectively netted approximately $1.2 million on the strikes. Most of the wallets had been funded within the previous 24 hours, had no prior trading history, and were all created in February 2026, according to CoinDesk.

The Iran conflict has become the largest stress test prediction markets have ever faced. Hundreds of millions of dollars were traded across Polymarket’s Iran-related markets, including strike-date contracts and markets tied to Khamenei’s removal from power. On Kalshi, the US-regulated platform, a single market asking whether Khamenei would leave office by March 1 attracted $54 million in trades, according to NPR and Fox Business.

The result has been a three-front crisis: suspected insider tradingThe buying or selling of securities using non-public information, typically illegal in regulated markets as it unfairly advantages the trader. on Polymarket’s offshore platform, a class-action lawsuit against Kalshi over a contractual clause that voided payouts when the mechanism of removal turned out to be death, and a legislative push in the US Senate to ban prediction markets war contracts outright.

Prediction Markets War Trades: The Magamyman Account

The account “Magamyman” placed its most conspicuous bet on February 28: a $32,000 wager that the US would strike Iran that day, when Polymarket’s odds placed the probability at roughly 17%, according to NPR. The trade was executed shortly before the first reports of explosions in Tehran.

Magamyman’s activity extended beyond a single market. The account had placed bets across multiple Iran-related contracts, collectively generating more than $553,000 in profit. The timing and pattern drew immediate attention from analysts and lawmakers.

Senator Chris Murphy of Connecticut stated plainly: “It’s insane this is legal. People around Trump are profiting off war and death.”

This is worth contextualizing. Polymarket’s offshore platform, where these trades occurred, is technically inaccessible to US-based users but remains reachable through virtual private networks. The platform’s US-based version, which would fall under Commodity Futures Trading Commission (CFTC) oversight, has not yet fully launched. The Trump administration dropped two Biden-era federal investigations into Polymarket earlier in 2026, according to NPR. Donald Trump Jr. serves as an adviser to Polymarket, and his firm 1789 Capital has invested millions in the company.

The Bubblemaps Evidence

Bubblemaps, a blockchain analytics firm, published findings on the social media platform X identifying six wallets that exhibited trading patterns consistent with prior knowledge of the strikes.

The largest single position involved an account that purchased over 560,000 “Yes” shares in the “US strikes Iran by February 28” market at approximately 10.8 cents per share, according to CoinDesk. When the market resolved at $1.00 per share after the strikes were confirmed, that position was worth nearly $560,000.

A second account purchased nearly 150,000 shares at 20 cents, producing a six-figure profit. The wallets showed visual clustering, suggesting they were “funded through similar paths,” according to Bubblemaps’ analysis.

None of this constitutes proof of insider trading on the prediction markets. The wallets could belong to aggressive speculators who read military intelligence indicators correctly. But the combination of fresh wallets, zero prior trading history, large positions at long odds, and near-perfect timing has proven difficult to explain through public information alone.

Kalshi’s Death CarveoutA contractual clause that prevents payouts when a specified outcome is caused by death, designed to prevent financial incentives to profit from fatal events.: $54 Million Frozen

Kalshi, which operates as a CFTC-regulated exchange, ran a market asking whether Khamenei would be “out as Supreme Leader of Iran” by March 1, 2026. The market attracted approximately $54 million in trading volume, according to Fox Business.

When Israeli strikes killed Khamenei on February 28, traders who had purchased “Yes” contracts expected payouts. They did not receive them. Kalshi paused trading and invoked what it called a “death carveout,” a contractual provision designed to prevent the platform from directly profiting from or incentivizing death.

CEO Tarek Mansour defended the decision: “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. That is what we did here.”

Traders disagreed. A $54 million class-action lawsuit was filed in US District Court for the Central District of California. The complaint argued that Kalshi’s contract language was “clear, unambiguous and binary,” and that the death carveout had not been adequately disclosed before Khamenei’s killing. The plaintiffs contended that consumers understood that “the most likely mechanism by which an 85-year-old autocratic leader would ‘leave office’ was through his death,” according to Fox Business.

Kalshi reimbursed approximately $2.2 million in trader fees and losses. The lawsuit seeks the full $54 million.

The Senate Response to Prediction Markets War Betting

Democratic senators had been raising concerns about prediction markets and war-related contracts before the Iran strikes occurred. On February 23, 2026, Senator Adam Schiff of California, along with Senators Catherine Cortez Masto, Richard Blumenthal, Cory Booker, Tim Kaine, and Jacky Rosen, sent a letter to CFTC Chair Michael Selig urging the agency to “halt prediction contracts that involve betting on physical injury, death or war,” citing legal authority under 17 CFR 40.11 and the Commodity Exchange Act.

The letter referenced specific markets that predated the Iran conflict: a Polymarket contract asking whether the Artemis II spacecraft would explode, a contract on Venezuelan President Nicolás Maduro’s removal (on which a trader reportedly netted more than $400,000), and a contract on the capture of the Ukrainian town of Myrnohad.

“These contracts present dangerous national security risks, including creating incentives to incite violence, foment geopolitical conflicts, and disclose classified information,” the senators wrote.

After the Iran strikes, Schiff introduced the DEATH BETS Act, which would strip the CFTC of discretionary authority over such contracts and write explicit prohibitions into law. Senator Blumenthal introduced a companion bill targeting fraud and insider trading on prediction platforms. Neither bill has yet received a committee vote.

The Structural Problem

The controversy over Iran-related prediction markets exposes a gap that existed before anyone placed a bet. Federal regulations already prohibit futures contracts based on assassinations, war, or terrorism under the Commodity Exchange Act. But those rules apply to CFTC-regulated exchanges. Polymarket’s offshore platform, where the most suspicious trading occurred, operates largely outside that jurisdiction.

Amanda Fischer of Better Markets, a financial reform advocacy group, stated that “prediction markets are promoting opportunities to bet on events that can only be seen as a proxy for war or assassination,” according to NPR.

The question of whether prediction markets create perverse incentivesAn incentive that produces unintended consequences opposite to its intended goal, causing a policy to worsen the problem it was designed to solve. is not new. The theoretical concern has always been that allowing financial stakes in geopolitical outcomes could, at a minimum, incentivize the disclosure of classified information by individuals seeking to profit from advance knowledge, and at worst, create financial motivation for violence itself. Similar concerns arose following controversial US military strikes in the region. The Iran trades have moved this from a thought experiment to documented trading patterns that regulators must now evaluate.

CFTC Chair Selig, who has pursued a deregulatory agenda toward prediction markets, had not publicly responded to the senators’ demands as of the March 9 deadline they set. His position puts him on a collision course with Democratic lawmakers who view the Iran trades as proof that existing safeguards are insufficient.

What Has Not Been Proven

It is important to state what remains unresolved. No regulatory body has formally accused any trader of insider trading. The Bubblemaps analysis identifies suspicious patterns, not proven violations. Senator Murphy’s reference to “people around Trump” was political commentary, not an allegation supported by evidence presented to law enforcement.

Polymarket has maintained that its prediction markets functioned as intended and that unusual trading patterns do not necessarily indicate insider knowledge. The platform has not been charged with any violation.

Kalshi’s death carveout, while controversial, may prove legally defensible if the company can demonstrate adequate disclosure of the provision. The class-action lawsuit will test this.

What is not in dispute is the scale: hundreds of millions of dollars were wagered on the timing and outcomes of military strikes that killed people. Whether the legal framework governing prediction markets war betting is adequate to the moment these platforms have created is now a question for Congress, the courts, and the CFTC.

In the hours before US and Israeli forces struck Iran on February 28, 2026, a series of trades on prediction market platforms exhibited characteristics that blockchain analysts and financial regulators associate with informed trading. The prediction marketsFinancial markets where participants wager on the probability of future events, with contract prices reflecting the market's implied likelihood of outcomes. war trades, their structure, and the regulatory gaps they exposed warrant detailed examination.

How Prediction Market Contracts Work

Prediction markets operate on binary outcome contracts. A trader purchases a “Yes” or “No” share in a market proposing a specific event (e.g., “US strikes Iran by February 28, 2026?”). Share prices fluctuate between $0.00 and $1.00, reflecting the market’s implied probability of the event occurring. If the event occurs, “Yes” shares resolve at $1.00; if not, they resolve at $0.00.

The profit margin is determined by the entry price. A trader purchasing “Yes” shares at $0.10 (implying a 10% probability) who sees the market resolve at $1.00 earns $0.90 per share. This means low-probability events offer the highest potential returns, which is precisely why early, large positions on unlikely outcomes attract scrutiny when those outcomes materialize.

Polymarket operates on the Polygon blockchain, a Layer 2 Ethereum scaling solution. Trades are executed on-chain, making wallet funding patterns, trade timing, and position sizes publicly auditable. This is how Bubblemaps, a blockchain analyticsThe examination of blockchain transactions and wallet patterns to identify suspicious activity, fund flows, and potential market manipulation. firm, was able to identify suspicious trading clusters in the prediction markets war contracts.

The Magamyman Trades: Technical Detail

The account “Magamyman” placed a $32,000 position on the “US strikes Iran by February 28” market when the contract was priced at approximately $0.17, implying a 17% probability, according to NPR. The trade was executed shortly before the first reports of explosions in Tehran.

Across multiple Iran-related contracts, the account generated more than $553,000 in profit. The account was not new; it had previously placed bets on geopolitical events, including a profitable trade in June 2025 on Israel-Iran military activity and a January 2026 trade on Venezuelan President Maduro’s arrest, according to NPR. This history complicates the insider-trading narrative: a pattern of aggressive geopolitical speculation is also consistent with a well-informed risk-taker who bets frequently and wins occasionally.

The Bubblemaps Wallet Cluster

Bubblemaps identified six wallets that exhibited correlated behavior, according to CoinDesk:

• All six were created in February 2026
• Most were funded within 24 hours of the strikes
• None had prior trading activity
• All purchased “Yes” shares in the same Iran strike market
• Funding paths showed visual clustering, suggesting common origin

The largest position: over 560,000 shares purchased at approximately $0.108 each. Resolution at $1.00 yielded nearly $560,000. A second wallet purchased roughly 150,000 shares at $0.20, producing a six-figure return. Combined profits across the six wallets totaled approximately $1.2 million.

On-chain transparency is a double-edged feature of blockchain-based prediction markets. It makes suspicious patterns identifiable but does not reveal the identity behind a wallet. Without KYC (Know Your Customer) requirements on Polymarket’s offshore platform, connecting wallets to individuals requires either voluntary disclosure or law enforcement subpoena of exchange records.

Kalshi’s Death CarveoutA contractual clause that prevents payouts when a specified outcome is caused by death, designed to prevent financial incentives to profit from fatal events.: Contract Design Under Stress

Kalshi’s “Khamenei out” market was structured as a binary contract: will Khamenei cease to be Supreme Leader by March 1, 2026? The contract attracted $54 million in trading volume on a CFTC-regulated exchange, according to Fox Business.

When the event’s resolution mechanism turned out to be an airstrike, Kalshi invoked a contractual clause it termed a “death carveout.” CEO Tarek Mansour described the rationale: the clause existed to “prevent people from profiting from death.” The company paused trading and ultimately did not pay out “Yes” holders.

The class-action lawsuit filed in the Central District of California challenges this on contract law grounds. The plaintiffs’ core argument is that the contract’s plain language asked whether Khamenei would leave office, not how. Death is one mechanism by which a head of state leaves office. The complaint contends that the carveout was not adequately disclosed and that Kalshi’s retroactive application constituted “deceptive” and “predatory” conduct.

Kalshi reimbursed approximately $2.2 million in fees and losses. The lawsuit seeks the full $54 million. The outcome will likely turn on whether the carveout was incorporated by reference into the contract terms traders agreed to, and whether a reasonable trader would have understood its implications.

Regulatory Architecture and the Prediction Markets War Gap

The Commodity Exchange Act, Section 5c(c)(5)(C)(i), authorizes the CFTC to prohibit event contracts that involve “terrorism, assassination, or other activity that is unlawful.” This provision predates modern prediction markets and was not designed with platforms like Polymarket or Kalshi in mind.

The regulatory gap operates on two levels:

Jurisdictional: Polymarket’s offshore platform, where the most suspicious trades occurred, falls outside CFTC jurisdiction. Americans accessing it via VPN are technically violating platform terms, but enforcement is minimal. The Trump administration’s decision to drop two Biden-era investigations into Polymarket, combined with Donald Trump Jr.’s advisory role and his firm 1789 Capital’s investment in the company, has drawn scrutiny from lawmakers and advocacy groups tracking the intersection of political access and financial interest.

Definitional: Even on regulated platforms like Kalshi, the line between a “geopolitical outcome” contract and a “death” contract is ambiguous. A market on whether a head of state will “leave office” is technically about political transition, but when the head of state in question is an 85-year-old autocrat during an active military campaign, the practical overlap with a death market is near-total.

Senator Adam Schiff’s DEATH BETS Act would address this by writing explicit prohibitions into statute, removing CFTC discretion. Senator Blumenthal’s companion bill adds fraud and insider tradingThe buying or selling of securities using non-public information, typically illegal in regulated markets as it unfairly advantages the trader. provisions specific to prediction platforms. Both bills face a Republican-controlled Senate unlikely to prioritize prediction market regulation.

The Perverse IncentiveAn incentive that produces unintended consequences opposite to its intended goal, causing a policy to worsen the problem it was designed to solve. Question

The theoretical concern about prediction markets and violence is straightforward: if individuals can profit financially from specific geopolitical events, this creates an incentive structure that could, in theory, motivate the disclosure of classified information (to front-run market-moving events) or, in extreme cases, the events themselves.

The senators’ February 23 letter to CFTC Chair Selig stated this directly: these contracts “present dangerous national security risks, including creating incentives to incite violence, foment geopolitical conflicts, and disclose classified information.”

Amanda Fischer of Better Markets argued that the platforms “are promoting opportunities to bet on events that can only be seen as a proxy for war or assassination,” according to NPR.

Prediction market proponents counter that these platforms aggregate information efficiently, that similar incentive structures exist in options and futures markets tied to defense stocks and oil prices (a point underscored by the oil price shock produced by the Iran conflict), and that banning specific contracts drives activity to less transparent offshore venues. The debate intensified after controversial US military operations raised questions about accountability and oversight in the region.

Neither argument resolves the core tension: the Iran trades have demonstrated that prediction markets war betting can generate hundreds of millions of dollars in volume on the outcomes of active military operations, and that at least some of that trading exhibits patterns consistent with informed trading. Whether the legal and regulatory framework can adapt quickly enough to address this is an open question.
