Washington's Scrutiny of Iran War Prediction

Iran War Bets Push Washington Into a Prediction-Market Crackdown

How well-timed wagers on U.S. strikes on Iran turned Polymarket and Kalshi into a Washington scandal — and why the crackdown is likely to stall.

On February 28, 2026, as U.S. and Israeli aircraft hit Iran and Ayatollah Ali Khamenei was killed hours later, one Polymarket account named "Magamyman" cleared roughly $553,000 on trades placed 71 minutes before the strikes went public. Within a month, four Senate and House bills, a bipartisan letter to the Commodity Futures Trading Commission and a criminal indictment of a U.S. Army Special Forces master sergeant had made prediction markets the most-scrutinised financial venue in Washington. The crackdown, however, is likely to fail — because the president's family is invested on both sides of the market, the CFTC chair is publicly siding with the platforms, and every Democratic bill is dying in a Republican-controlled Agriculture committee.

That is the story worth reading past the headlines. The Iran war did not create Washington's suspicion of Polymarket and Kalshi; it forced the political economy of prediction markets into the open. Who traded, who benefits from lax rules, and who is now moving to write them are three tightly linked questions with the same answer: the Trump orbit.

What the traders actually knew

The evidentiary spine of the scandal is now unusually thick. According to Al Jazeera, an on-chain analyst tracked 38 accounts he believes were controlled by one person; they netted more than $2.14 million betting correctly on the February 28 strikes, with cryptocurrency deposits into the wallets beginning six days before any public reporting suggested imminent conflict. As of late March there were 355 live Polymarket contracts tied to Iran-war outcomes.

The pattern extended past the opening salvo. The Associated Press, via NPR, reported that at least 50 brand-new Polymarket accounts placed sole, substantial bets on a U.S.–Iran ceasefire in the minutes before President Donald Trump announced one on Truth Social in April. A separate episode in the oil market followed the same choreography: 15 minutes before Trump posted that he would pause strikes on Iran's energy infrastructure, an estimated $580 million in crude and S&P 500 e-Mini transactions moved in the direction of the coming announcement, economist Paul Krugman told NPR.

The empirical work has caught up fast. In an April 2026 working paper, Joshua Mitts and Ofir estimated $143 million in aggregate anomalous profit across roughly 210,000 wallet–market pairs on Polymarket between 2023 and early 2026, using a five-factor statistical screen combining bet size, timing, profitability and directional concentration. A parallel Gomez-Cram et al. paper, posted on SSRN and running against Polymarket's full transaction history — 1.72 million accounts and $13.76 billion in cumulative volume — flagged 1,950 accounts as suspected insiders under a lifecycle-and-conviction heuristic. The academic consensus, in short: informed trading on Polymarket is neither anecdotal nor marginal.

The legislative dam breaks — and then holds

Within four weeks of the Iran strikes, Democrats introduced five separate bills. On March 5, 2026, Senators Jeff Merkley and Amy Klobuchar unveiled a measure barring members of Congress, the president and vice president from trading event contracts. On March 10, Sen. Adam Schiff introduced the DEATH BETS Act (S. 4035) — the "Discouraging Exploitative Assassination, Tragedy, and Harm Betting in Event Trading Systems Act" — which would amend Section 5c of the Commodity Exchange Act to prohibit any registered entity from listing contracts that "involve, relate to, or reference terrorism, assassination, war, or any similar activity, as determined by the Commission."

The companion House version, H.R. 7942, was introduced by Rep. Mike Levin on March 16 and referred the same day to the House Agriculture Committee. Sen. Chris Murphy and Rep. Greg Casar followed with the BETS OFF Act, which sweeps in "government actions" and any event "where an individual knows or controls the outcome." Rep. Jamie Raskin's H.R. 8123 goes further, prohibiting contracts on elections, sports, U.S. or foreign military action and executive/legislative/judicial acts — carving out only hedges of commercial risk.

Each of these bills sits in the House or Senate Agriculture Committee, both chaired by Republicans who have been publicly cool to new restrictions. The chair of the House Agriculture Committee, Rep. G.T. Thompson, welcomed CFTC Chair Michael Selig at his first oversight hearing without endorsing any of the pending prohibitions. Selig himself is the government's most consequential player here — and the least neutral.

The regulator is on the platforms' side

The Dodd-Frank Act, per the Council on Foreign Relations, already gives the CFTC statutory authority to bar event contracts "contrary to the public interest" that involve terrorism, assassination, war, gaming or illegal activity. On paper, the tools exist. In practice, the agency has done nearly nothing. A March 2026 letter from Sen. Jack Reed and 20 Senate Democrats to Selig documents the record bluntly: the CFTC "has not brought a single enforcement case involving prediction markets" and its only public actions have been two internal Kalshi cases involving $246.36 and $5,397.58 in illicit profit. "That signals a lax oversight regime and will not deter insider trading," the senators wrote.

Selig has read from a different script. As chairman he has publicly defended Kalshi against state prosecutors, called Arizona's March 17 criminal charges against the platform "entirely inappropriate," and, in an op-ed cited by NPR, argued that event contracts serve "legitimate economic functions." The BBC reported that the CFTC has also withdrawn a Biden-era proposal to ban sports and election-related contracts. Selig is currently the only sitting commissioner on the five-seat CFTC, giving him unusual latitude.

The political geometry compounds this. Donald Trump Jr. is a paid strategic adviser to Kalshi, which he joined in January 2025; his venture firm, 1789 Capital, invested in Polymarket in August 2025, a month after the Justice Department dropped its investigation into the platform. The president himself, asked about the first criminal case, likened it to "Pete Rose betting on his own team" — a public signal, in CFR's reading, that the administration will not tighten the current regime.

The Van Dyke case — proof and pretext

On April 23, 2026, the Southern District of New York unsealed an indictment against Master Sgt. Gannon Ken Van Dyke, an active-duty U.S. Army Special Forces communications specialist who helped plan Operation Absolute Resolve, the raid that captured Nicolás Maduro. According to BBC and court records reported by NPR, Van Dyke placed roughly $33,000 in bets on Polymarket's offshore protocol between December 27, 2025 and January 2, 2026, at prices around 7 cents per share, and cleared more than $409,000 when U.S. forces extracted Maduro from Caracas on January 3. He faces counts of wire fraud, commodities fraud and misuse of nonpublic government information.

The case is the first U.S. criminal prosecution for insider trading on a prediction market. It is being marketed by the CFTC and by Polymarket's chief legal officer as evidence that the system self-corrects. The uncomfortable subtext: Van Dyke allegedly evaded Polymarket's U.S. ban simply by using the offshore protocol the CFTC fined the company $1.4 million in 2022 to keep Americans off. Nearly four years later, the offshore route remains the dominant venue for geopolitical wagering, and, as CFR notes, "an active-duty warfighter has been charged with trading on classified information" precisely by exploiting the gap the CFTC never closed.

Diplomat View

The Iran-strike bets have handed Democrats their sharpest anti-corruption weapon of the second Trump term and, simultaneously, exposed why the weapon will not fire. Every ban bill is under Republican jurisdiction in Agriculture; the sole functioning CFTC commissioner is publicly aligned with the industry; the president's son is on the payroll of both major platforms; and the president himself has framed insider trading on a covert military raid as merely rooting for the home team. The DEATH BETS Act and BETS OFF Act will not pass this Congress. A revived enforcement drive at the CFTC will not begin under Selig. What will happen instead is targeted DOJ prosecution — Van Dyke is a template, not an anomaly — and continued state-court skirmishing led by attorneys general in Arizona, Minnesota and Nevada, who have the strongest constitutional footing to police these venues as gambling.

The forecast changes on three conditions: a second CFTC commissioner is seated who breaks with Selig; a Republican from a state where prediction markets are actively litigating (Ohio, Arizona) co-sponsors a war-contracts ban; or a documented insider trade traces to someone with an executive branch email address. Absent any of those, the crackdown is theater.

What to watch:

• CFTC action on the Reed letter. The senators demanded that Selig "immediately halt trading in event contracts tied to U.S. military operations." A formal response, or refusal, is the first regulatory tell.
• House Agriculture markups. H.R. 7942, H.R. 8123 and H.R. 8148 are all parked in committee. Any scheduled hearing on prediction-market legislation before the August recess signals movement; continued silence is the base case.
• Van Dyke plea proceedings in SDNY. A cooperation agreement that names a Polymarket contact or reveals the trade path across the offshore protocol would give the Justice Department its first real leverage over the platform's U.S. compliance posture.
• Arizona v. Kalshi. A state-court ruling either way reshapes the federal-preemption fight the CFTC has been picking with governors, and directly affects whether Kalshi can continue to operate as a national exchange.

The Bottom Line

The Iran-war bets did not prove that prediction markets are lawless — they proved that Washington's most powerful actors are financially aligned with keeping them that way. Until a Republican co-sponsor or a second CFTC commissioner changes the arithmetic, the DEATH BETS and BETS OFF Acts are messaging bills, and the Van Dyke indictment is a one-off. The scandal has moved from Polymarket to the Oval Office, but the leverage has not.
