Pronóstico: Bitcoin Up or Down - August 20, 1AM ET

Platform comparison

Market context

The market currently prices Bitcoin's hourly performance on 20 August 2026 at 1AM ET with zero probability of an up close, implying near-certainty of a down or flat close on Binance's BTC/USDT pair. This represents an extreme skew in a binary hourly candle contract—a one-hour window where Bitcoin's open and close prices will determine settlement through Polymarket's conditional token mechanics, with USDC collateral backing positions on Polygon.

Hourly Bitcoin candles exhibit minimal directional bias over extended periods. Historical analysis of similar one-hour intervals shows roughly 50-51% close above open across major exchanges, with slight upward drift reflecting Bitcoin's long-term appreciation. The current 0% probability suggests either technical dysfunction in market pricing, a data feed issue, or positioning by traders holding offsetting positions elsewhere. Comparable hourly contracts on Polymarket have rarely sustained such extreme probabilities absent clear settlement ambiguity.

Traders monitoring this contract should track Binance's system status and any scheduled maintenance windows affecting the BTC/USDT pair between 1AM and 2AM ET on the settlement date. Broader Bitcoin volatility catalysts—Federal Reserve announcements, macroeconomic data releases, or significant custody movements—could influence intraday momentum, though single-hour candles often reflect noise rather than directional conviction. The settlement mechanism depends entirely on Binance's official 1H candle data once finalised, making exchange operational continuity the primary dependency for accurate resolution.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Polymarket Qué Es. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.
