Trade: Will KT Rolster make a roster change before July?

Market context

KT Rolster's League of Legends roster will likely experience at least one personnel change—a player departure or signing—between now and 30 June 2026. The current active lineup comprises PerfecT, Cuzz, Bdd, Aiming, Ghost, and Pollu. The 88% implied probability on Polymarket's order book reflects substantial confidence in roster flux occurring within this seven-month window, suggesting traders view stability as unlikely for a competitive esports organisation operating in the LCK.

Esports rosters historically turn over significantly during off-seasons and mid-season windows. KT Rolster has made roster adjustments in previous years, with the 2024–2025 cycle seeing multiple LCK teams shuffle players ahead of international competition. The high probability reflects both the structural reality of esports labour markets—where player movement accelerates around spring and summer splits—and KT's track record as an organisation willing to make changes to maintain competitiveness. Teams typically announce roster moves via official channels or Liquipedia updates, which serve as the settlement criteria.

Traders should monitor the LCK's official schedule and KT's announcements for contract expirations, injury updates, or performance-related decisions. The settlement window encompasses the typical period when organisations finalise rosters for summer competition. Any official signing or departure, whether driven by underperformance, contract negotiations, or strategic rebuilding, will trigger resolution to "Yes". The absence of any such changes by 30 June would be the exception rather than the norm in professional League of Legends.

Resolution source

This market settles from the official outcome published at https://liquipedia.net/leagueoflegends/KT_Rolster. 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 "Will KT Rolster make a roster change before July?" are the same as any other PolyGram sporting 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 88% YES, you'll receive shares that pay $114 if YES resolves true — a 14% 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?

$771 in lifetime turnover and $2K of resting liquidity puts this market in the below the median by volume for sports 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 $67 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 around 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.

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.
