May 15 in 72 Hours: The Post-CPI Prediction Market Map

April CPI printed +3.8% YoY this morning -- hottest in three years, driven by energy and shelter components. With Fed hike odds clearing 52% for the first time this cycle, here's how prediction markets are pricing the week's biggest open questions.

Contracts to Watch

1. Strait of Hormuz Traffic Normal by May 15 -- 0.25% Yes ( Polymarket)
This contract expires Thursday. The crowd has fully priced it as terminal -- 0.25% is noise, not probability. UANI's May 11 shipping update confirms open transits fell to near-zero since May 6, against a pre-conflict baseline of ~138 daily. CENTCOM has redirected 62 commercial ships since the April 13 blockade. The IMF Portwatch 7-day moving average of 60+ transits required for YES has no realistic path in three days. For crude traders: Hormuz normalization is a Q3 2026 story at the earliest.

2. Michelle Bowman Confirmed as Fed Chair -- 0.05% Yes ( Polymarket)
Hot CPI reliably renews Fed chair succession chatter, so this is worth addressing directly: markets say no. Bowman was confirmed as Vice Chair for Supervision in June 2025 (51-46 Senate vote). This separate contract asks whether she'll ascend to the full Chair role, replacing Powell. Despite the inflation print and Trump's ongoing pressure campaign, the Senate math for a new confirmation doesn't add up before the June FOMC. Implication: Powell chairs June's meeting. Whatever the hike decision is, it's his call.

3. Will Hezbollah Disarm by December 31? -- 17% Yes ( Polymarket)
The sleeper on today's board. Post-Lebanon ceasefire dynamics have this at a non-trivial 17% with over six months to resolution -- a probability that would have seemed absurd a year ago. For energy desks tracking Middle East risk: any credible disarmament progress would compress the risk premium baked into oil, independent of the Iran situation.

4. Bitcoin $150k by June 30 -- 1.35% Yes ( Polymarket | Robinhood)
BTC is trading around $81k today (per Polymarket price range markets). Getting to $150k by June 30 requires ~85% upside in 49 days. The crowd prices it at 1.35%. For context: CME launches Bitcoin Volatility Futures (BVI) on June 1, giving traders a regulated instrument for implied-vol exposure without directional risk. If you're bullish on crypto uncertainty, the vol product -- not the $150k binary -- is the cleaner trade.

What to Watch into Thursday
The May 15 binary resolves in 72 hours: Hormuz to NO, Starmer (6.55%) as the wildcard if UK politics deteriorates. The bigger macro question is whether June Fed pricing continues to shift post-CPI -- watch the Bowman contract as a real-time sentiment gauge. CME BVI launch June 1 is the most consequential near-term event for crypto derivatives desks.

UPDATE -- May 13, 7:00 AM ET: 48 Hours to Deadline

May 15 is now 48 hours away. The picture is bleak.

Prediction market snapshot (current):

• Iran peace deal by May 15: Near 0% -- deadline effectively priced as failed, no MOU signed
• Hormuz reopening by May 31: 7% (Polymarket, $408K vol)
• Hormuz reopening by June 30: 31% (Polymarket, $4.9M vol)
• Hormuz reopening by Dec 31: 78% (Polymarket)
• US-Iran nuclear deal before September: 37% (Kalshi)

Iran's FM was in Beijing last week -- no breakthrough. The Trump-Xi summit now underway (May 13-15) has explicitly downplayed Iran; Trump stated Tuesday he "didn't need China's help" on Iran. Tehran's 14-point counterproposal -- centering on reparations ($270B claimed) and nuclear enrichment rights -- remains unaccepted. Both are US red lines.

Energy market context:

• Brent crude: ~$113 (+57% since Feb 28 war start)
• OPEC production near 20-year lows
• Hormuz traffic remains at ~6% of pre-war normal (IMF PortWatch)
• April CPI: +3.8% YoY -- energy accounting for >40% of the gain

The binary on Thursday: Markets have already priced deadline failure -- the question is whether Trump reacts to the missed May 15 date with an announcement or silence. A more dangerous inflection is Iran's 30-day ultimatum expiring ~June 1-2: Iran's 14-point proposal set that as its own escalation tripwire. If June 1 passes without resolution, the IRGC has pre-announced a basis for resuming operations.

Watch for:

• White House statement Thursday morning on deadline outcome
• Whether IRGC formally invokes the missed deadline as justification
• Brent $113 is the current floor -- escalation pushes toward $125+; a genuine MOU would crater crude
