Bitcoin Up or Down on August 11?

Platform comparison

Market context

This market tracks whether Bitcoin's price on 11 August 2026 at noon ET will be higher or lower than its price the previous day at the same time, using Binance spot pricing. The 34% probability assigned to an upward move reflects modest bearish lean among traders, suggesting the crowd expects a slight decline or consolidation over the 24-hour window.

Bitcoin's intraday volatility at fixed timestamps has historically been difficult to predict with precision. Analysis of comparable single-day directional bets on major cryptocurrencies shows that when probability sits between 30–40%, it typically indicates genuine uncertainty rather than conviction. Over rolling 24-hour periods, Bitcoin has moved up or down with near-equal frequency absent major macroeconomic shocks. The current implied probability of 34% for upside suggests traders are pricing in either mild headwinds or mean-reversion expectations from preceding price action.

Catalysts to monitor include Federal Reserve communications, broader equity market movements, and any significant regulatory announcements affecting cryptocurrency markets. Bitcoin's correlation with US equity indices has remained material through 2026. Traders should watch for scheduled economic data releases on 10–11 August, particularly employment figures or inflation indicators that could shift risk appetite. Additionally, any statements from major central banks regarding monetary policy stance could influence capital flows into or out of risk assets during this window. Binance's own operational status and any platform-level issues would directly affect settlement accuracy.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Bitcoin Up or Down on August 11? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
