Prediction Market Roundup March 05, 2026

The US just fired Precision Strike Missiles at Iranian targets for the first time in combat, and Polymarket traders are now pricing an 81.5% probability that Iran closes the Strait of Hormuz within three weeks. That’s up from 74.5% yesterday, with $2.6 million trading hands in the last 24 hours alone. Military Times is reporting active combat use of weapons systems that were previously theoretical, while BBC shows destruction across Tehran and new missile attacks hitting the UAE. The market’s telling you this isn’t containable anymore.

The Hormuz market—sitting at $11.4 million total volume—reflects something bigger than oil price speculation. When Iranian state media shows damage across their capital and the Guardian reports Senate war powers votes being drafted, the 18.5% “no” side looks increasingly disconnected from reality. Traders watching Trump’s Washington Post-reported call for Kurdish assistance understand we’re in active escalation mode, not diplomatic positioning.

Regime Collapse Gets Real Odds

Here’s what changed overnight: “Will the Iranian regime fall by March 31?” is now at 14.6¢ on $1.2 million in 24-hour volume. That’s still a longshot, but it’s moved from “essentially impossible” territory. The market’s giving it roughly 1-in-7 odds with 26 days left, which tells you traders are pricing actual scenarios where military pressure creates internal collapse.

The more interesting play is the June timeframe market at 37.5%—that’s jumped significantly as traders extend their thinking beyond immediate crisis. $606k traded today on a question that seemed academic two weeks ago. The spread between March (14.6%) and June (37.5%) shows the market believes if regime change happens, it’s more likely a months-long process than a sudden coup.

CBS News reporting on assassination plots targeting Trump, Biden, and Haley adds context here. When you’ve got active plots against top US officials alongside open military conflict, the stability calculations change fast. The 62.5% “no” side on June collapse is betting the regime survives summer, but that’s down from where we were before strikes on Tehran.

The Succession Market Nobody Wanted

$925k traded today on “Will Mojtaba Khamenei be the next Supreme Leader of Iran?” and it’s holding at 61%. This is genuinely bizarre—you don’t usually see active succession markets while the current leader is still making decisions. But when Israeli strikes are hitting the capital and Times of Israel reports repatriation flights for citizens, traders are gaming out transition scenarios.

The 61¢ price means if Khamenei exits power (whether through health, assassination risk, or forced retirement), Mojtaba’s the market’s pick for successor. His son inheriting would break with traditional clerical succession, but under wartime pressure, institutional norms break down. The 39% “no” side is betting on either status quo continuation or a more conventional religious figure taking over.

This connects directly to the regime stability question—if you think the government falls entirely (14.6% by March, 37.5% by June), then succession markets become moot. These are complementary bets on different collapse timeframes and mechanisms. For traders trying to build positions across prediction market strategies, understanding how these markets interact matters more than any single price.

The Peace That Isn’t Coming

“US x Iran ceasefire by March 15?” sits at 10.5% with $582k in 24-hour volume. Ten days out, that’s essentially a “no” from the market. When you’ve got Military Times reporting first combat use of advanced missile systems and BBC showing ongoing attacks spreading to UAE territory, the idea of negotiations producing results in 10 days looks detached from reality.

The interesting thing here is the volume—over half a million traded today on what’s basically a settled question. That suggests either very aggressive contrarians buying the 10.5% “yes” side, or more likely, traders locking in 89.5% returns on a near-certain outcome. The Washington Post reporting Trump actively recruiting Kurdish forces tells you the military strategy is still expanding, not winding down.

Compare this to the Hormuz closure market where meaningful volume reflects genuine uncertainty. The ceasefire market is trading more like insurance than speculation—people paying 10.5¢ for the tiny chance they’re wrong about war trajectory. When Axios reports primary fights between House Democrats turning nasty partly over war policy positions, you see how this conflict is reshaping domestic politics too, making near-term peace even less likely.

Texas Politics Gets Market Attention

Away from the war, $1.1 million traded today on “Will Ken Paxton win the 2026 Texas Republican Primary?” at 13.5% yes. That’s a significant move given the Axios headline about Democratic primary fights in Texas—when political coverage intensifies, trader attention follows. Paxton surviving impeachment didn’t translate to primary security, and the market’s giving him roughly 1-in-7 odds.

The 86.5% “no” side reflects Republican primary voters’ appetite for change after years of controversy. This market shows how prediction markets vs traditional polling can diverge—polls might show name recognition, but markets price actual turnout and opposition coordination. The Times reporting on political earthquakes in North Carolina state legislature suggests 2026 primaries across the board are getting more volatile than usual.

What to Watch

The Strait of Hormuz market moves with every new headline about regional attacks—watch for any statements from Iranian leadership about keeping shipping lanes open. The regime collapse markets will react to any signs of internal dissent or military defections. And if peace talks actually materialize before March 15, that 10.5% ceasefire market becomes the trade of the month. Stock futures are already slipping and oil pushing higher per WSJ, so traditional markets are confirming what Polymarket traders priced days ago.
