Bitcoin price on August 13?

Platform comparison

Market context

Bitcoin's noon ET price on 13 August 2026 will be determined by the closing value of the BTC/USDT 1-minute candle on Binance at that precise moment. The market currently shows 0% implied probability for "Yes," suggesting traders are pricing in either extreme confidence in a specific price range or minimal liquidity at present. On Polymarket, this contract settles via USDC on Polygon, with conditional tokens reflecting the binary outcome tied to Binance's published candle data. The resolution mechanism is straightforward: if the spot price falls between two price brackets, the higher bracket resolves affirmatively.

Historical Bitcoin price action over comparable timeframes reveals substantial volatility. In August 2021, Bitcoin moved roughly 20% across the month; in August 2023, intraday swings of 5–8% were routine. A single noon snapshot eliminates intraday noise but remains sensitive to overnight Asian and European trading sessions preceding the ET midday close. The 0% probability reading likely reflects either an extremely tight price band in the market's construction or early-stage illiquidity before the contract gains trader attention.

Catalysts shaping Bitcoin's trajectory through summer 2026 include Federal Reserve policy signals, macroeconomic data releases, and institutional adoption announcements. Regulatory developments—particularly from the SEC or CFTC—can trigger sharp repricing within hours. Traders should monitor scheduled economic calendars, central bank communications, and any major cryptocurrency exchange or custody announcements in the weeks preceding mid-August. Geopolitical events and traditional market stress also historically correlate with Bitcoin volatility.

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

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 PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
