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

Platform comparison

Market context

Bitcoin's five-minute price movement between 8:55PM and 9:00PM ET on 13 July will determine settlement, with resolution anchored to Chainlink's BTC/USD oracle feed rather than spot exchange prices. The 100% YES crowd probability reflects the mathematical reality that any upward or flat movement resolves affirmatively, creating a heavily skewed outcome space. On Polymarket, this contract trades as a conditional token pair on Polygon, with YES and NO positions denominated in USDC and settled against Chainlink's data stream—a departure from traditional spot market pricing that matters for traders monitoring basis risk between exchange quotes and oracle feeds.

Five-minute Bitcoin windows historically exhibit minimal directional bias when viewed in isolation, though the broader intraday volatility context shapes realistic probabilities. During periods of elevated market uncertainty or scheduled macroeconomic releases, even short windows can see sharp reversals; conversely, during low-volatility sessions, flat or marginally positive closes dominate. The current 100% pricing suggests either illiquidity in the NO position or market participants treating any upside scenario as overwhelmingly likely given the settlement window's brevity and the asymmetric payoff structure.

Traders should monitor whether major economic data, Fed communications, or spot market disruptions occur near the settlement window. Chainlink's BTC/USD feed aggregates multiple price sources with a slight lag, meaning rapid flash crashes or exchange-specific volatility may not fully register on-chain before the five-minute window closes. Recent Bitcoin spot volatility has centred on macroeconomic sentiment rather than intraday technicals, suggesting the outcome hinges more on whether the broader market environment shifts during that specific minute than on any scheduled catalyst.

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

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.
