GDP Day: The First Economic Reckoning -- Pahlavi at 6.55%, Hormuz at 0.45%, and What $133M in C

GDP Day: The First Economic Reckoning -- Pahlavi at 6.55%, Hormuz at 0.45%, and What $133M in Contracts Expiring Saturday Tells Us

Fresh US military strikes on Iranian targets overnight have resolved the "ceasefire through May 28" Polymarket contract as NO -- $612K settling against longs this morning. Every ceasefire contract through May 26, May 27, and May 28 has now resolved NO. What's left: $133M+ in contracts expiring Saturday (May 31) with the peace deal at 7.5% and the diplomatic situation deteriorating.

And this morning at 8:30 AM ET, traders get the first real answer to the question nobody has wanted to ask: what did three months of war actually do to the US economy? GDP revision, Core PCE, and Jobless Claims all drop simultaneously. Consensus: GDP revised sharply higher to 2.0% (from initial 0.5%), Core PCE 3.3% YoY. Oil rebounding 2-3%. Bitcoin below $73,000. Gold below $4,400.

Top Contracts to Watch

1. US x Iran Permanent Peace Deal by May 31 -- 7.5% Yes ( Polymarket) | $64.4M total volume | $7.7M 24h

This is the big one. The market says 7.5% chance of a permanent peace deal in 72 hours. With overnight strikes and Iran condemning US actions as "bad faith" and the Doha delegation gone since May 27, that 7.5% is telling you the crowd believes this expires worthless Saturday.

For energy traders, this matters directly: Brent rebounding 2-3% this morning because overnight strikes remind the market that the May 31 diplomatic fantasy was never priced into oil properly. If the deal collapses at 7.5%, the question shifts to what happens to the June and December forward curves.

2. US-Iran Nuclear Deal by May 31 -- 6.85% Yes ( Polymarket) | $4.3M total volume

Almost identical to the peace deal price (6.85% vs 7.5%), yet fundamentally different contracts. A nuclear deal requires Iran to accept uranium transfer provisions that Khamenei publicly vetoed. This market is pricing the probability that position reverses in 72 hours.

The 65-basis-point premium for peace over nuclear is the market saying: a non-nuclear framework is marginally more possible than an actual uranium deal. Both are essentially impossible by Saturday. The real nuclear deal market to watch is the June 30 deadline contract, which was at 41.5% as recently as May 25.

3. Will Reza Pahlavi Lead Iran in 2026? -- 6.55% Yes ( Polymarket) | $11.3M total volume | Expires December 31, 2026

Here's the market getting overlooked in all the ceasefire noise. Iranian regime fall by Saturday prices at 0.15%. But Reza Pahlavi -- son of the last Shah, living in exile -- leading Iran by year-end prices at 6.55%. That's a 43x multiple on the same underlying story, expressed over a longer timeframe.

The 6.55% isn't pricing a violent collapse. It's pricing negotiated transitions, political fracture, or a scenario where the ongoing conflict gradually erodes the regime's grip through 2026. This is the only Iran market with genuine long-dated exposure. If you think the regime is more fragile than 0.15% implies but the near-term is just noise, Pahlavi at 6.55% through December is the position to hold.

4. Strait of Hormuz Traffic Returns to Normal by End of May -- 0.45% Yes ( Polymarket) | $29.3M total volume

Zero point four five percent. That's the market's probability that the world's most critical oil chokepoint reopens in 72 hours. Oil traders already know this. The July Hormuz contract at 38% is where the real debate sits.

$29.3M in total volume has accumulated on a market that's priced as rounding error. That's traders buying cheap insurance and sellers taking the other side. With overnight strikes putting the ceasefire under fresh stress, this goes to zero.

5. Will Bitcoin Hit $150k by June 30? -- 1.35% Yes ( Polymarket | Robinhood) | $5.8M 24h volume

Bitcoin fell below $73,000 this morning on Iran escalation and safe-haven USD flows. To resolve YES, BTC needs to more than double in 33 days. CME launches 24/7 digital asset derivatives trading tomorrow (May 29) -- expanded access doesn't help when the underlying is selling off.

1.35% is the price of tail insurance at any given moment. The $5.8M 24h volume is momentum traders keeping this zombie alive. For futures traders: Bitcoin Friday futures on CME are a far cleaner vehicle for short-dated crypto views than a binary priced at 1.35%.

Bonus: World Cup Dark Horse Markets

Scotland and South Korea both trade at 0.25% to win the 2026 FIFA World Cup (kicks off June 12). Scotland: $28M total liquidity. South Korea: $31M. Identical pricing, $59M combined. These are the benchmark liquidity pools for World Cup prediction market activity right now.

CME Event Contracts Watch

Today's 8:30 ET triple data drop is the critical input for rate path markets. Lisa Cook (Fed) signaled readiness to hike if inflation warrants it. The GDP revision (2.0% consensus vs initial 0.5%) will be the first formal accounting of what the war did to Q1. If Core PCE beats 3.3% YoY, rate hike probability markets move immediately.

CME goes 24/7 on all digital asset derivatives tomorrow (May 29). First weekend with continuous crypto futures coverage.

What to Watch Today

8:30 AM ET -- GDP revision (2.0% consensus), Core PCE April (3.3% YoY), Jobless Claims (209K). Rate hike markets move on any PCE surprise.

Energy -- EIA crude oil inventories at 5:00 PM ET (consensus -4.4M bbl). Fresh strikes near Hormuz-adjacent infrastructure = physical/paper divergence risk.

Reza Pahlavi -- Any statement from the exile opposition moves the 6.55% contract fast. $171K liquidity means thin market, big moves on news.

May 31 Cluster -- 72 hours. Watch for any last-minute diplomatic signal from Witkoff or Araghchi. A surprise extension statement could spike peace to 15-20% on thin end-of-week liquidity.
