Trade: Tunis: Kimmer Coppejans vs Dali Blanch

Market context

Kimmer Coppejans and Dali Blanch are scheduled to meet in a tennis match at the Tunis event on 15 May 2026. The market's current 0% implied probability for Coppejans reflects either minimal liquidity on the order book or a strong consensus positioning favouring Blanch. At Polymarket, such extreme probabilities often indicate sparse trading activity rather than definitive assessment; the spread between bid and ask prices typically widens considerably at the tails, making execution difficult for traders seeking to challenge the consensus.

Coppejans, a Belgian player ranked outside the top 200, has competed primarily on the Challenger circuit with limited ATP-level exposure. Blanch's recent form and ranking relative to Coppejans would typically anchor expectations, though historical upsets in lower-tier professional matches occur with sufficient frequency that 0% probabilities warrant scrutiny. Comparable Challenger-level encounters frequently see the lower-ranked player win outright, particularly on clay courts where Tunis events are typically held.

Traders should monitor official tournament draws and any late withdrawals or injury announcements in the fortnight before the match. Tunis events occasionally experience scheduling adjustments due to weather or venue constraints. The settlement window closes 22 May, allowing a week-long buffer beyond the original date; any delay beyond that triggers a 50-50 resolution. Current order book depth will determine whether meaningful entry points exist for contrarian positioning.

Resolution source

This market settles from the official outcome published at https://www.atptour.com/en/scores/current. 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 "Tunis: Kimmer Coppejans vs Dali Blanch" 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.

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 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.

How active is this market?

$249K in lifetime turnover and $276K of resting liquidity puts this market in the top 10% by volume for tennis contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.

Last 24 hours alone saw $249K 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.
