Bitcoin Up or Down - May 22, 5PM ET

Platform comparison

Market context

This market settles on whether Bitcoin's price at 5PM ET on 22 May 2026 closes at or above its opening level for that specific one-hour candle on Binance's BTC/USDT pair. The 0% implied probability reflects the market's current assessment that traders see negligible likelihood of an intraday uptick during this window. On Polymarket, positions are denominated in USDC and settled via conditional tokens on Polygon, meaning resolution hinges entirely on Binance's published 1H candle data once finalised—the close price versus open price for that single sixty-minute interval.

Hourly Bitcoin price action rarely sustains directional conviction without external catalysts. Historical precedent from similar intraday contracts shows that when crowd probability compresses to zero, the underlying event often reflects either extreme market conditions or genuine indifference to the timeframe. A 0% reading suggests traders expect downward pressure or flat-to-negative momentum during that hour, though such extreme probabilities can shift rapidly if macroeconomic announcements, Federal Reserve communications, or significant on-chain activity materialise in the preceding days.

Traders monitoring this contract should track scheduled economic releases and central bank statements in the week prior, as these typically drive volatility across crypto markets. Bitcoin's correlation with equity futures and Treasury yields remains a primary driver of hourly moves. Additionally, any major exchange outages, regulatory announcements, or significant liquidation cascades could alter intraday momentum substantially. The settlement window closes at 10PM ET on 22 May, providing a four-hour buffer after the candle closes for Binance data to finalise before conditional tokens resolve.

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 PolyGram, 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.

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.
