Market context

The White House Press Office issues a "full lid" when the President's scheduled public activities conclude for the day, signalling to media that no further official events, statements, or appearances will occur before midnight. This distinction matters operationally: a full lid differs from partial lids (lunch breaks, travel intermissions) and requires explicit Press Office confirmation using that specific terminology. Traders monitoring this market need to distinguish between routine scheduling announcements and formal lid declarations, as the resolution hinges on precise language rather than inference from the President's calendar.

Historical precedent shows full lids occur with regularity but unpredictable timing. During typical White House operations, lids are called between 4:00 PM and 7:00 PM ET, though weekend schedules and travel days shift this window considerably. The 100% implied probability reflects the near-certainty that *some* full lid will be issued within the May 18–23 window across multiple days, rather than confidence about any single day. Traders should note that the market's five-day span substantially increases the likelihood of at least one full lid being called, which explains the ceiling probability.

Programmatic monitoring requires real-time feeds from the White House Press Office's official channels—primarily the @WhiteHousePressSecy Twitter account and the press briefing schedule published on whitehouse.gov. Recent scheduling patterns indicate the Press Office typically issues lids after the President's final public event, often following afternoon departures or evening social functions. Conditional orders tied to specific time thresholds (e.g., triggering at 6:15 PM if no lid has been called) offer practical automation for traders managing this market across multiple days.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

Polymarket Review UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
