Bitcoin price on August 13?

Platform comparison

Market context

Bitcoin's noon ET price on 13 August 2026 will be determined by the Binance BTC/USDT 1-minute candle close at that specific timestamp. The market currently shows 0% implied probability for "Yes," suggesting traders expect the price to fall outside whatever bracket the market defines, or that liquidity and participation remain minimal this far forward. Resolution hinges on Binance's recorded close price; if the actual price lands between two bracket boundaries, the higher bracket wins.

Historical Bitcoin volatility across multi-year windows provides limited predictive power for a single noon timestamp two years hence. Comparable long-dated Bitcoin price markets on Polymarket and Kalshi have typically seen wider probability distributions and deeper liquidity when settlement approaches within six months; markets settling beyond 18 months often trade thinly, with implied probabilities clustering at extremes rather than reflecting genuine consensus. The 0% reading here likely reflects sparse order flow rather than confident bearish conviction. Betfair and Smarkets, which cater primarily to sports and near-term events, carry minimal Bitcoin derivatives volume, making cross-platform comparison difficult for this maturity.

Traders monitoring this market should track macroeconomic policy shifts, institutional adoption milestones, and regulatory announcements affecting Bitcoin's medium-term trajectory. The Federal Reserve's interest-rate path, corporate treasury allocations, and any major spot or futures ETF developments will shape sentiment. Fee structures across platforms—Polymarket's 2% settlement fee, Kalshi's variable maker-taker model, and traditional bookmakers' overround—will compress expected value differently depending on bracket width and order placement timing as the date approaches.

Methodology

We read Bitcoin price on August 13? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). On-chain settlement clears in minutes — the fastest payout path of the four.
