Bitcoin Up or Down - August 20, 1AM ET

Platform comparison

Market context

This market settles on whether Bitcoin's price on Binance's BTC/USDT pair closes at or above its opening level during the one-hour candle beginning 20 August 2026 at 1AM ET. The resolution hinges on a single hourly bar's open and close values, making it a straightforward intraday directional test that traders often use to validate execution timing on algorithmic strategies or to stress-test conditional order logic across different market regimes.

The 0% probability reflects either extreme illiquidity in the market or a technical issue with the interface, as hourly Bitcoin moves have historically resolved to "Up" roughly 50–52% of the time across multi-year datasets. Single-hour candles are inherently noisy; mean reversion and momentum both occur within this timeframe depending on volatility clustering and order-book depth. Traders building bots or copy-trading systems typically use such granular markets to calibrate slippage assumptions and to verify that their data feeds (whether WebSocket streams or REST polling) align with Binance's canonical OHLC values before deploying capital on longer timeframes.

Catalysts affecting the one-hour window are difficult to predict precisely, though macro economic data releases, Federal Reserve communications, or significant spot or derivatives liquidations can trigger sharp moves. Traders should monitor Binance's own API documentation for any scheduled maintenance windows that might affect data availability, and cross-check the 1H candle close against multiple sources—including Binance's REST endpoint and historical klines—to avoid disputes over rounding or timestamp interpretation when the settlement window closes on 20 August 2026 at 6AM ET.

Methodology

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

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.

FAQ

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
