Pronóstico: Bitcoin Up or Down - August 20, 7AM ET

Platform comparison

Market context

The market prices a single hourly candle on Binance's BTC/USDT pair opening at 7AM ET on 20 August 2026, with resolution determined by whether Bitcoin's closing price meets or exceeds its opening price during that sixty-minute window. The 0% implied probability reflects the market's current assessment that traders see negligible likelihood of an up candle at that specific moment. On Polymarket, this contract settles via USDC on Polygon, with conditional token mechanics allowing traders to hedge directional exposure across the broader crypto market or isolate intraday volatility expectations.

Hourly Bitcoin candles historically close higher roughly 51–52% of the time across major exchanges, suggesting near-random walk behaviour over single-hour periods. The current 0% pricing deviates sharply from this baseline, indicating either extreme bearish sentiment baked into August 2026 expectations or illiquidity in this particular contract limiting price discovery. Similar one-hour directional markets on Polymarket typically trade between 40–60% when no specific catalyst is present, making this outlier valuation noteworthy for contrarian positioning.

Traders monitoring this candle should track Bitcoin's macro momentum in the weeks preceding 20 August, including any Federal Reserve policy announcements or significant cryptocurrency regulatory developments that could establish directional bias. Binance's own operational status and any scheduled maintenance windows matter operationally, though the exchange's historical uptime remains robust. The settlement window closes five hours after candle completion, providing sufficient time for Binance data finalisation before conditional token redemption.

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 Polymarket Qué Es, 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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.
