May 26 Deadline Dies at 7.5% as US Strikes Iran During Ceasefire -- The May 31 Cluster and CME'

The May 26 Peace Deadline Dies Today: US Struck Iran on Monday While Negotiating

Today's the day prediction market traders have been watching all month: the "US x Iran permanent peace deal by May 26" contract hits expiration, and it's going to settle NO. Odds sat at 7.5% as of market open -- meaning the crowd already priced in failure, and the news confirmed it. But the really interesting story isn't just that this contract expires near-zero. It's why -- and what it tells you about every other Iran binary still on the board.

US Central Command confirmed new "self-defense strikes" Monday against Iranian missile launch sites and boats attempting to place mines near the Strait of Hormuz -- while ceasefire negotiations were still active. Iran confirmed explosions near Bandar Abbas. Trump simultaneously posted on Truth Social that the deal is "largely negotiated." These things happened on the same day. That's the market you're trading.

Today's Prediction Market Odds


Top Contracts to Watch

1. US x Iran Permanent Peace Deal by May 26 -- 7.5% Yes ( Polymarket)
$19.2M total volume, $6.2M in the last 24 hours -- that's peak settlement-day activity. This contract expires today and settles NO. No permanent peace deal was signed. The MOU framework currently on the table is a 60-day roadmap for further negotiation, not a binding agreement. As of this morning, Iran's FM is in Doha for continued talks, both sides are still wrangling over the Strait of Hormuz tolls, uranium disposal, and sanctions relief sequencing. "The deal with Iran will either be a great and meaningful one or there will be no deal" -- Trump, May 24. Prediction markets believe him: no deal today, 7.5% was generous.

2. Strait of Hormuz Traffic Returns to Normal by May 31 -- 2.85% Yes ( Polymarket)
$26.2M in total volume, $1.4M yesterday. This contract tells you everything you need to know about where we actually are vs. where the headlines make it sound like we are. Trump says the deal is "largely negotiated" and includes Hormuz reopening. Markets price reopening by May 31 at 2.85%. The reason: US struck Iranian vessels near Hormuz on Monday, Iran has a $200B+ annual oil export economy riding on this negotiation, and the MOU framework explicitly defers the Hormuz timeline to a 60-day process. Even under the best-case scenario, normalization by May 31 means less than two weeks of implementation. The crowd isn't buying it.

3. Will the Iran Ceasefire Continue Through May 24 -- 96.3% Yes ( Polymarket)
$10.9M total volume. Note what the market is NOT saying: ceasefire = peace deal. 96.3% say guns stay mostly quiet through the reference date. But that same market gives a formal deal this month 7.5%. This is the "frozen conflict premium" -- the crowd believes the kinetic pause holds while formal resolution stays out of reach. Low-intensity strikes (Monday's CENTCOM operation) don't violate the ceasefire threshold. Iran isn't reopening Hormuz. Neither side wants to be seen as the one who broke talks. So you get a ceasefire that holds at 96% and a formal deal that dies at 7.5%.

4. US Obtains Iranian Enriched Uranium by May 31 -- 1.25% Yes ( Polymarket)
$18.5M total volume. The nuclear question is where the hardest disagreements live. White House insists the MOU commits Iran to surrendering enriched uranium -- "No dust? No dollars." Iranian officials and state media have offered "different interpretations." Khamenei's camp called US control over their nuclear program a "fantasy" as recently as this week. The market agrees with Tehran's version: 1.25% chance the US physically obtains enriched uranium in the next five days.

5. Will the Iranian Regime Fall by May 31 -- 0.35% Yes ( Polymarket)
$31M total volume -- this is the single largest-volume contract in this cluster. 0.35% is essentially zero. Despite a 39-day war, oil sanctions, and severe economic pressure, Iran's political structure is intact. The National Catholic Register's analysis this morning called this an "uneasy end to an elusive war" -- emphasis on uneasy, not collapse. The regime fall market at 0.35% is the cleanest summary of where Iran actually stands: damaged economically, but not existentially threatened.

CME Update: Bitcoin Volatility Futures Launch June 1

Meanwhile, something fresh for futures traders: CME officially certified the Bitcoin Volatility Index futures contract (ticker: BVI) with CFTC for launch on June 1, 2026. This is the BTC equivalent of the VIX -- you're trading implied volatility itself, not price direction. Contract size is $500 x the CME CF Bitcoin Volatility Index (BVXS). Initial listings cover June and July expiry. If BVXS hits 80, one contract = $40,000 notional. This is directly relevant to anyone already trading crypto futures or using BTC options for portfolio hedging. Note the timing: Bitcoin's $150k-by-June-30 prediction market contract sits at 1.35% on Polymarket ( Polymarket | Robinhood). The crowd says BTC doesn't hit $150k by June 30. With BVI launching that same week, you can now take a view on whether BTC vol spikes regardless of where price goes.

What to Watch

All the remaining Iran contracts cluster around May 31 -- five days out. Hormuz (2.85%), uranium (1.25%), regime fall (0.35%) are all priced near zero. The consensus is frozen conflict: ceasefire holds, formal resolution deferred into the MOU's 60-day framework, and the hard issues (nuclear, Hormuz tolls, uranium disposal) stay unresolved past month-end. The key catalyst that would move these odds materially upward doesn't exist yet. For oil traders: Hormuz stays closed means the physical/paper premium persists. For rates traders: Fed hike 50+bps by June is at 0.25% -- the crowd sees Warsh holding, and the Iran-driven energy inflation doesn't change that calculus. Watch Tuesday's MOU talks in Doha for any language on Hormuz as the next potential catalyst.
