Market outcomes
| FTSE 100 (UKX) Up or Down on June 3? | 50% YES | 50% NO |
The FTSE 100 will close on Wednesday, 3 June 2026, and this market resolves based on whether that closing price exceeds the prior trading day's close. The current order book on Polymarket reflects a 50–50 split, indicating traders see genuine uncertainty in the near-term direction of the UK's primary equity benchmark. At parity, neither bullish nor bearish positioning dominates; the market is pricing in roughly equal odds of a daily gain or loss.
Single-day moves in the FTSE 100 are typically modest in magnitude. Historical volatility suggests daily swings of 0.5–1.5 per cent are common, with larger moves concentrated around earnings seasons, monetary policy announcements, or macroeconomic surprises. A 50 per cent implied probability on a day-to-day direction reflects the index's inherent noise and the absence of scheduled major catalysts on that specific date. Comparable daily-direction markets on major indices rarely drift far from 45–55 per cent unless a significant event is imminent.
Traders monitoring this market should track Bank of England communications and eurozone data releases in the days preceding 3 June, as sterling and European equity sentiment drive FTSE positioning. Oil prices and mining stocks—which constitute a substantial portion of the index—remain sensitive to global growth expectations and energy markets. Any unexpected inflation data or geopolitical developments in late May could shift the order book materially. Absent such catalysts, mean reversion and technical support levels will likely determine the day's direction.

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.wsj.com/market-data/stocks/emea), 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.

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 50%, a $50 stake on YES buys roughly 100 shares; if YES resolves true those shares pay out at $1.00 each (a $100 gross payout, or +$50 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. For "FTSE 100 (UKX) Up or Down on June 3?", the considerations above apply directly — Trade size should reflect the binary nature of the payoff: even a 70% probability event resolves NO 30% of the time, so any single position can lose 100% of staked capital.
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.
