Market context
Jerome Powell would have to stop holding the Fed chairmanship for this market to resolve Yes; an announcement of resignation or a future handover date is not enough if he remains in post. In practice, the clean way to track it is by the actual transfer of authority, not the press cycle around it. That matters because prediction markets on office departures often trade as if a named successor or an end-of-term date is decisive, when the settlement rule here is stricter: Powell must actually cease being Chair by the deadline.
The current 0% implied probability sits alongside a major timing shift: Powell’s second four-year chair term ran to 15 May 2026, and reporting this month indicated he would step down from the chair role while remaining a Fed governor, with Kevin Warsh confirmed by the Senate on 13 May 2026 to succeed him after that term. Brookings noted the succession path, and CryptoBriefing cited Powell as having confirmed his planned step-down. For a trader using conditional orders or automated alerts, the key comparison is historical: Fed chairs have often continued in another Fed role after the chair term ends, so a successor confirmation does not itself settle this market unless the handover has actually taken place.
The live catalysts are straightforward: any Federal Reserve statement, White House announcement, Senate confirmation timing, and the exact swearing-in or assumption date for the next chair. Programmatically, the market should be watched against the deadline condition: if Powell remains Chair past 11:59 PM ET on the listed date, the outcome is No even if a successor has been announced or confirmed. The practical trigger is the chair title changing hands, not the surrounding personnel process.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
