Market outcomes

XRP Up or Down - May 31, 5:25PM-5:30PM ET 0% YES100% NO

Market context

This market resolves based on whether XRP's price according to Chainlink's XRP/USD data feed is higher at 5:30PM ET on 31 May 2026 than at 5:25PM ET the same day. The five-minute window captures intraday volatility in one of the cryptocurrency market's most actively traded assets. Current order book depth on Polymarket shows negligible liquidity at the YES side, with the crowd-implied probability sitting at 0%, reflecting either extreme bearish positioning or insufficient trading activity to establish meaningful price discovery on this specific micro-timeframe contract.

Five-minute directional bets on XRP have historically resolved based on technical momentum and order flow rather than fundamental shifts. Comparable ultra-short-duration cryptocurrency markets typically exhibit high variance outcomes, with resolution dependent on whether large market participants execute trades during the window or whether the asset drifts on minimal volume. The 0% probability reading suggests traders are either absent from this particular contract or have positioned entirely on the DOWN side, though such extreme readings often indicate thin order books rather than genuine conviction.

Traders monitoring this contract should track XRP's broader price action in the days preceding 31 May, as any significant moves or announcements affecting the asset could establish directional bias heading into the settlement window. Chainlink's data feed aggregates prices from multiple exchanges, so resolution depends on that specific oracle rather than any single spot market. Liquidity conditions and volatility clustering in the final minutes before 5:25PM ET will likely determine outcomes more than any scheduled catalyst.

This market settles from the official outcome published at https://data.chain.link/streams/xrp-usd. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

How to trade this market step by step

The mechanics for trading "XRP Up or Down - May 31, 5:25PM-5:30PM ET" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

  1. Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
  2. Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
  3. Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
  4. Size your position. If you stake 100 USDC at 0% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
  5. Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
  6. Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.

Key terms

YES / NO share
A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
CLOB
Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
Liquidity
USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
UMA optimistic oracle
The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
Slippage
The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
Conditional token
ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note

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.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
