Bitcoin Up or Down - July 13, 8:55PM-9:00PM ET

Platform comparison

Market context

Bitcoin's five-minute price movement between 8:55 PM and 9:00 PM ET on 13 July will determine settlement, with resolution sourced exclusively from Chainlink's BTC/USD oracle feed rather than spot exchange prices. The 100% YES probability reflected in current Polymarket pricing suggests traders view upward movement or price stability as near-certain within this narrow window. On-chain settlement occurs via USDC on Polygon, with conditional tokens minting against the Chainlink data point captured at the close of the five-minute interval.

Ultra-short timeframes of this duration rarely sustain downward pressure without triggering liquidations or algorithmic selling across major venues. Historical precedent from comparable five-minute Bitcoin windows shows that sub-minute volatility typically resolves toward equilibrium rather than sustained decline, particularly during US evening hours when trading volumes remain elevated across spot and derivatives markets. The 100% crowd probability reflects this structural reality: genuine downward movement requires either a flash crash, major news event, or coordinated selling within 300 seconds—outcomes traders assess as statistically improbable absent external shock.

Traders monitoring this contract should track Chainlink's oracle update frequency and any scheduled maintenance windows that might delay data feed publication. Recent network congestion on Polygon has occasionally delayed conditional token settlement by minutes, though this affects resolution timing rather than price accuracy. No major Bitcoin announcements or regulatory developments are scheduled for 13 July evening, leaving the market dependent on organic trading dynamics and any spillover volatility from equity or commodity markets during US closing hours.

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 PolyGram, which mirrors the Polymarket order book directly.

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.

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.
