Market context

Bitcoin needs to finish the Binance 1-minute 12:00 ET candle above the contract strike on 21 May. With the market already at 98% Yes, the remaining pricing implies only a narrow margin for error, which is typical where the reference point is a single exchange candle rather than a daily close. Comparable Bitcoin day-specific markets have often been more sensitive to venue-specific wicks and short-lived volatility than to the wider trend, so a high Yes price is not the same as a guarantee. For accessibility, the “no-KYC up to $1,500” label means users can open small positions without full identity verification, but larger activity will usually require more checks; that matters for German users because events on offshore crypto prediction venues can still sit in a grey area under the GlüStV, while US persons face the broader reach of the CFTC regime even if the market is crypto-settled.

The main things to watch are Binance spot liquidity around noon ET, any US macro release or Fed comment landing near the settlement window, and crypto-specific news that can move the minute candle rather than the day’s average price. Recent coverage from Bloomberg and Reuters has continued to frame Bitcoin as sensitive to ETF flow changes, regulatory headlines and sudden risk-on/risk-off shifts, which is relevant because this contract keys off one timestamped print, not a broader session range. Any dependency on Binance data quality also matters: if the exchange’s BTC/USDT 1-minute candle at 12:00 ET is distorted by a brief spike, that is what decides the market.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram 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.
