Polymarket’s Iran Betting Surge Helped Spark Washington’s Prediction Market Crackdown Bill

A surge of more than $500 million in Iran-related wagers on prediction markets has become the catalyst for new federal legislation that would explicitly ban betting on war, terrorism, and death through CFTC-registered platforms.

Sen. Adam Schiff introduced the DEATH BETS Act on March 10, 2026, targeting contracts tied to assassination, armed conflict, terrorism, or an individual’s death. Rep. Mike Levin is carrying companion legislation in the House.

The bill’s sponsors drew a direct line between the Iran betting frenzy and the need for new rules. “We already saw what that looks like: over half a billion dollars was wagered on the timing of U.S. military strikes on Iran alone,” Levin said in the announcement.

Iran Betting Volume on Polymarket Caught Washington’s Attention

Polymarket logged a record $478 million in single-day notional volume during the Iran-strike trading surge, with politics-related markets accounting for $220 million of that total. The platform’s Iran conflict contracts became a flashpoint after six newly funded wallets, flagged by blockchain analytics firm Bubblemaps, placed roughly $1.2 million in bets on a U.S. strike on Iran shortly before it happened.

Schiff’s office also cited a Kalshi market asking whether Ali Khamenei would be “out as Supreme Leader,” which had reached $54 million in trading volume before the platform paused it. The combination of massive volume and suspicious timing gave lawmakers a concrete example to build their case around.

“Betting on war and death creates an environment in which insiders can profit off of classified information,” Schiff said in the press release announcing the bill.

What the DEATH BETS Act Would Actually Prohibit

The legislation would explicitly bar any CFTC-registered entity from listing event contracts involving terrorism, assassination, war, or an individual’s death. Rather than relying on the CFTC’s existing discretionary public-interest authority, the bill removes ambiguity by writing the prohibition directly into statute.

The push builds on earlier pressure. In February 2026, Senate lawmakers had already pressed the CFTC over prediction markets involving physical injury, death, or war. The DEATH BETS Act converts that pressure into binding law.

Whether the bill captures offshore platforms like Polymarket directly or only CFTC-registered entities like Kalshi is a critical distinction. Polymarket operates from an offshore jurisdiction and nominally blocks U.S. IP addresses, but its markets have repeatedly drawn American attention and trading activity. The legislation as described targets CFTC-registered entities, though broader enforcement actions could follow if Congress signals intent.

The regulatory trajectory here echoes the pattern developing around other crypto oversight efforts. Congress has been racing to pass frameworks before political windows close, and the DEATH BETS Act adds prediction markets to that queue.

Polymarket’s Regulatory Exposure and What Comes Next

Polymarket already has a CFTC enforcement history. In 2022, the platform settled with the agency and paid a $1.4 million fine for offering illegal binary options to U.S. customers. It subsequently restructured to operate offshore, but the Iran-strike episode demonstrated that geographic barriers have not insulated the platform from Washington’s scrutiny.

The Iran volume spike also raised questions about market integrity beyond just the ethics of war betting. The Bubblemaps flag on six wallets placing well-timed bets worth $1.2 million echoes the kind of insider-trading concern that regulators across traditional markets treat as a top enforcement priority.

For the broader prediction market sector, the bill’s progress through committee will be the next milestone to watch. Both Polymarket and Kalshi are now named in the Congressional record as examples of why the legislation exists. If the DEATH BETS Act advances, platforms will need to decide whether to proactively delist sensitive geopolitical contracts or wait for enforcement to force the issue.

Bitcoin, meanwhile, traded at roughly $89,926, up 0.6% over 24 hours, with about $36 billion in daily volume. The prediction market crackdown has not directly moved crypto prices, but it adds another thread to the tightening regulatory fabric that continues to shape how digital asset platforms operate in or adjacent to U.S. markets.
