Market context

Ethereum is trading a little above $2,100 heading into the noon ET Binance close that will settle this market. That puts the benchmark close near the lower half of the main public brackets, with recent readings from Fortune showing ETH at $2,116.35 on 21 May and $2,120.69 on 20 May. On that basis, the market is not asking for a large move to decide the payout, but it is sensitive to a modest intraday break either way. The crowd view should be read against that narrow price band rather than as a call on the broader trend.

Comparable cases suggest the last few hours matter more than the headline level. Robinhood’s prediction-market quotes have recently put sizeable probability on ETH finishing above $2,050, while Polymarket’s hourly-style pricing has clustered around the $2,100-$2,200 zone, implying traders expect range-bound trade unless a late catalyst shifts spot. Because this market settles on Binance’s 1-minute candle close at 12:00 ET, temporary wicks or fast reversals around the fixing time can matter more than the session’s earlier direction. If the reported close lands exactly on a bracket edge, the higher range wins, which slightly favours traders looking for a boundary test.

The main catalysts are the US session’s liquidity and any fresh moves in broader crypto or macro risk assets before the settlement window closes. No company-specific event drives ETH here, so the trade is mostly about whether spot can hold above the next round-number support or slip back through it before noon ET. Binance’s live ETH/USDT tape is the key reference, with CF Benchmarks not applying here; the decisive factor is simply the final Binance 1-minute close at the settlement timestamp.

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 PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

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.

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 PolyGram?

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