Warsh Locked In at 100%: What the Fed Chair Market Means for Rate Futures -- Cuba Military Clash at 37%

Two prediction market signals that have not made the front page: the Fed Chair race is effectively over per the crowd, and a US-Cuba military confrontation is pricing near a coin flip for year-end.

Today's Prediction Market Odds


Top Contracts to Watch

1. Kevin Warsh Confirmed as Fed Chair -- 100% Yes ( Polymarket)
With $60M+ in total volume across all Fed Chair outcomes, the crowd has made a unanimous call: Kevin Warsh is the next Federal Reserve Chair. Bowman ($8.8M volume, 0.05%) and Shelton ($22.2M, 0.05%) are effectively priced out. The high 24-hour volume on both contracts reflects NO sellers locking in near-certainty. Warsh is the most hawkish credible candidate on the list -- he dissented against QE2 in 2010 and has consistently advocated for balance sheet normalization. After today's +3.8% CPI print, this matters: rate futures traders should model a Warsh-led Fed as a hawkish regime change, not a continuation.

2. US Strike on Cuba by December 31 -- 37% Yes ( Polymarket)
37% is not tail risk. Cuba's president publicly warned in April that a US military strike is now "a real possibility." Trump's maximum pressure campaign cut off oil shipments, triggering three nationwide blackouts in Cuba in March, and a White House official called Cuba a "failing nation" the US may need to "help." Related markets: US-Cuba military clash at 41%, US invasion at 23%. For macro traders, a Cuba confrontation hits Caribbean shipping lanes and signals US willingness to open a second military front while Iran remains active.

3. Strait of Hormuz by May 15 -- 0.25% Yes ( Polymarket)
The deadline arrives in 48 hours and is already priced NO on $14.6M in volume. The paired Iran peace deal (1.15% YES) resolves NO alongside it Thursday. Watch for the next diplomatic framework Iran proposes after May 15 -- that will set crude's direction for late May.

4. Bitcoin $150k by June 30 -- 1.35% Yes ( Polymarket | Robinhood)
This contract was at 15% in late April. Hot CPI plus hawkish Fed Chair signals equal crypto headwinds. $5.8M in 24h volume here is traders selling NO at near-certainty.

5. Hantavirus Pandemic in 2026 -- 8.65% Yes ( Polymarket)
Holding steady at elevated levels on $8.7M total volume. Not person-to-person, so pandemic mechanics are limited, but the persistent 8-9% range reflects genuine uncertainty.

What to Watch
Senate confirmation hearing dates for Warsh are the sleeper catalyst for rate futures repricing. Cuba escalation moves fast -- any incident in the Straits of Florida or SOUTHCOM posture shift will register in these contracts before headlines catch up. May 15 Hormuz and Iran contracts close Thursday morning; watch for new contract creation showing the post-deadline Iran framework.

UPDATE -- Senate Confirms Warsh

It just happened: the Senate confirmed Kevin Warsh as Federal Reserve Chair, bringing the leadership transition into its final stage.

This closes out the prediction market position -- at 100% probability the crowd was right, and the confirmation is complete.

What Warsh inherits on day one:

• CPI (April): +3.8% YoY -- hottest in 3 years
• PPI (April, released this morning): +1.4% m/m, +6.0% YoY -- biggest gain since 2022
• Hormuz blockade: 7% probability of reopening by May 31
• Fed funds rate: 3.50%-3.75% -- inherited, not of his making

Warsh's known hawkish instincts -- the main reason markets were skeptical when Trump first floated his name -- may be precisely what the situation demands. The dual CPI/PPI shock this week suggests the Fed's current pause is already behind the curve.

The real question is whether Warsh acts preemptively before the June FOMC meeting, or waits for the full May data picture (PCE due May 30). A June hike is not consensus yet, but it is on the table in a way it was not 48 hours ago.
