Market context

Bitcoin's spot price on Binance's BTC/USDT pair will be sampled at a single moment—the close of the 1-minute candle at noon Eastern Time on 31 May 2026—to determine whether it exceeds a specified threshold. This narrow settlement window eliminates intraday volatility as a factor; only the precise closing price at that timestamp matters. The 100% crowd probability reflects either an extremely bullish consensus or a threshold set substantially below current market expectations, making the distinction between these scenarios material for traders evaluating the true risk profile.

Historical Bitcoin price action shows that single-point-in-time settlements at major exchanges have resolved predictably when thresholds are set conservatively relative to prevailing spot rates. The Binance BTC/USDT pair typically exhibits tight spreads during US trading hours, reducing the likelihood of extreme slippage between the implied probability and actual settlement. However, flash crashes, exchange connectivity issues, or coordinated liquidations during the noon ET window have occasionally created discrepancies between Binance's recorded close and broader market prices, as occurred during the March 2020 volatility spike.

Traders should monitor macroeconomic calendar events scheduled for late May 2026, particularly US inflation data releases and Federal Reserve communications, which historically correlate with Bitcoin volatility. Regulatory announcements from the CFTC or SEC regarding spot Bitcoin ETF custody standards could also shift positioning in the final weeks before settlement. The specific noon ET timestamp means that Asian and European market closes will have already settled, potentially anchoring price discovery before the US session opens.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Legal UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

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 it cost to trade on Polymarket Legal UK?

Zero. Polymarket Legal UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

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.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket Legal UK triggers a quick verification flow that finishes in 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.
