Trade: Bitcoin Up or Down - May 10, 4:20PM-4:25PM ET

Market context

This market tracks whether Bitcoin's price according to Chainlink's BTC/USD data feed will be higher or flat at 4:25PM ET on 10 May 2026 compared to its level at 4:20PM ET that same day. The five-minute window captures intraday volatility at a specific moment, with settlement determined exclusively by Chainlink's oracle data rather than spot exchange prices. The current order book on Polymarket shows the crowd pricing this outcome at 100% probability for "Up," reflecting either extreme confidence in upward movement or minimal trading activity establishing a floor price.

Five-minute Bitcoin price movements historically exhibit near-random walk characteristics, with directional bias largely dependent on broader market conditions in the preceding hours. During periods of consolidation or low volatility, such tight timeframes show roughly 50/50 directional splits, whilst strong trending days see persistence in the established direction. The 100% implied probability suggests either that traders expect significant bullish catalysts immediately before the window or that the market has attracted minimal liquidity, leaving the order book uncontested at extreme prices.

Traders should monitor Bitcoin's price action and broader crypto market developments in the hours preceding 4:20PM ET on that date. Macroeconomic announcements, Federal Reserve communications, or major institutional flows can shift intraday momentum substantially. The Chainlink feed's specific methodology and any potential latency differences from spot exchanges warrant attention, as discrepancies between oracle and market prices occasionally emerge during volatile periods.

Resolution source

This market settles from the official outcome published at https://data.chain.link/streams/btc-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 "Bitcoin Up or Down - May 10, 4:20PM-4:25PM 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 100% YES, you'll receive shares that pay $100 if YES resolves true — a 0% 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.

How active is this market?

$105K in lifetime turnover and $0 of resting liquidity puts this market in the top 30% by volume for up or down contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

Last 24 hours alone saw $105K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

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.

Frequently asked questions

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.
