Bitcoin price on July 21?

Platform comparison

Market context

Bitcoin’s noon Eastern close on 21 July finished in the high-USD 65,000s on the Binance BTC/USDT feed, with the market still trading above 66,000 USDT earlier that morning before easing back towards the mid-65,000s later in the day.[1][5][6] Against that backdrop, the current 0% YES crowd-implied probability on the contract is a sharp outlier rather than a balanced view of the underlying price action, especially because comparable prediction venues were still heavily clustered around the 66,000–68,000 band for the same date.[2][4]

That gap is best read as a question of contract design and timing rather than a broad disagreement on direction. The settlement depends on the exact Binance 1-minute candle close at 12:00 ET, not the day’s headline high, daily close, or broader spot range, so traders have to anchor to a very narrow timestamp.[1] Historical Bitcoin swings of a few hundred dollars within a single session are routine, and the day’s range already spanned roughly 65,700 to 66,700 USDT on major market data feeds, which is enough to shift a one-minute settlement bracket materially.[6]

For catalysts, the main dependencies are the Binance spot order book and any US macro releases or crypto-specific headlines that land around the noon ET window, because those can move BTC quickly enough to change a single-minute close.[1][6] Recent Binance market commentary showed BTC briefly surging through 66,000 USDT on 21 July before reversing, which is consistent with how fast the contract can reprice around intraday volatility.[1] By contrast, Binance’s own longer-horizon price-prediction page remains broadly constructive on Bitcoin, but that sort of multi-month forecast has little direct bearing on a noon-fixed settlement event.[3]

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.
