Market outcomes

Aris BSA vs. Panionios 100% YES0% NO

Market context

Aris BSA will face Panionios in a Greek Basketball League fixture scheduled for 25 April at 11:15 AM ET. The market currently reflects a 100% implied probability for Aris BSA victory, with settlement occurring by 2 May 2026. This pricing emerges from Polymarket's order book, where traders have positioned heavily on an Aris win, leaving minimal liquidity on the Panionios side. Such extreme probabilities typically indicate either substantial confidence in the favourite or thin trading volume that has allowed one-sided positioning to dominate the book.

Aris BSA enters as the stronger historical performer in Greek basketball, having established itself as a consistent playoff contender in recent seasons. Panionios, by contrast, operates at a lower competitive tier within the league structure. The current 100% probability reflects this disparity in squad quality and recent form, though such extreme pricing leaves no margin for upset scenarios—injuries, tactical adjustments, or unexpected performance variance that occasionally materialise in live sport.

Traders monitoring this market should track team news through the settlement window, particularly injury announcements or roster changes in the final week before the fixture. The Greek Basketball League's scheduling occasionally experiences disruptions; postponements would extend the market's resolution date, whilst outright cancellations without rescheduling would trigger the 50-50 settlement clause. Current market depth suggests limited appetite for backing Panionios even at prohibitive odds, indicating confidence in Aris's superiority is broadly shared amongst active traders.

Resolution source

This market settles from the official outcome published at https://www.esake.gr/. 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 "Aris BSA vs. Panionios" 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 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?

$2K in lifetime turnover and $0 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.

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.

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.
