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

Platform comparison

Market context

Bitcoin’s 1AM ET close on 20 July 2026 is the sole determinant for this contract, which currently prices the “Up” outcome at 0% on Polymarket. Traders accessing the market via Polygon use USDC to buy conditional tokens, with resolution locked to Binance’s BTC/USDT 1H candle data once finalized by the UMA oracle. The zero probability reflects a near-universal consensus that the candle will close lower than its open, a stance shaped by recent intraday volatility.

Historically, 1AM ET candles on Mondays in July have shown a 68% tendency to close down when the preceding Asian session dips, as seen in July 2024 and 2025 when BTC opened near $64,700 but closed below $64,500 within the hour [2]. The current 0% YES pricing aligns with this pattern, suggesting the market expects the same intraday weakness to persist, especially given the mixed outlook for the second half of 2026 noted by analysts [2].

Key catalysts include the US inflation data release scheduled for 8:30AM ET on 20 July, which often triggers immediate volatility in crypto markets, and any unexpected Binance network maintenance announcements that could delay candle finalisation. Traders should monitor the 15-minute BTC/USDT charts on Binance for early signs of downward momentum before the 1AM ET candle opens, as these often set the tone for the full hour [6].

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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 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.
