Market outcomes
| XRP Up or Down on May 27? | 10% YES | 90% NO |
This market resolves based on XRP/USDT price movement between two specific noon timestamps on consecutive days in May 2026, using Binance's 1-minute candle closes as the settlement source. A "Yes" resolution requires the May 27 close to exceed the May 26 close; a "Down" resolution requires the opposite. The current order book on Polymarket is pricing a 22% probability of upward movement, reflecting market participants' assessment that XRP is more likely to decline or remain flat over that 24-hour window.
Intraday price movements in major cryptocurrency pairs typically exhibit mean-reversion characteristics over single-day horizons, particularly for established assets like XRP which trades with substantial liquidity across multiple venues. Historical volatility patterns suggest that noon-to-noon comparisons often resolve to modest directional moves rather than sharp reversals, which contextualises why the crowd is weighting downside or stability more heavily than upside. The 22% YES probability aligns with typical market-maker pricing for low-probability directional bets on liquid pairs over short timeframes.
Traders should monitor XRP's broader market positioning in May 2026, including any regulatory developments affecting Ripple or the broader cryptocurrency sector, as these could influence intraday volatility and directional bias. Macroeconomic data releases and Bitcoin's price action during that period will likely drive correlated movement in altcoins. The settlement mechanism's reliance on a single Binance candle close means that flash volatility or order book depth at precisely noon ET on May 27 could influence resolution, making execution risk a consideration for positions held into the settlement window.
This market settles from the official outcome published at https://www.binance.com/en/trade/XRP_USDT. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
For this market, the resolution date is 27 May 2026. A UMA proposer can submit the outcome from that moment; the two-hour dispute window closes at , and assuming no counter-claim is staked, winning USDC clears to trader balances by approximately .
If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. Because this market resolves from a publicly verifiable feed (https://www.binance.com/en/trade/XRP_USDT), the probability of dispute is materially lower than the overall 0.5% PolyGram baseline — most disputes occur on markets with ambiguous wording or non-public resolution sources.

Minimum order size on PolyGram is $1.00, with no maximum cap aside from available book depth. Orders route into Polymarket's on-chain CLOB on Polygon; the matching engine pairs YES buyers with NO buyers atomically — every executed trade is settled on-chain with no counterparty risk. For "XRP Up or Down on May 27?", order-book behaviour for this market reflects the underlying volatility of the outcome — patient limit orders typically fill closer to mid than market orders.
The trade ticket includes a slippage box (default 2%, configurable 0.1%-10%) that caps the worst-case entry price. At the current YES price of 10%, a $100 stake on YES buys roughly 1,000 shares; if YES resolves true those shares pay out at $1.00 each (a $1,000 gross payout, or +$900 profit). If NO resolves, the shares are worth $0. Slippage tolerance and resting-order depth determine the actual fill.
PolyGram charges 0% house edge — no spread mark-up, no rake on winnings, no withdrawal fees beyond network gas. The platform earns exclusively from optional features (copy-trade boosts, advanced order types, the yield vault on idle USDC); the trading surface itself is at-cost.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
