Derry City FC vs. PFK CSKA Sofia

Platform comparison

Market context

Derry City FC must overturn a one-goal deficit against PFK CSKA Sofia in the second leg of their UEFA Europa League first qualifying round tie, with the match kicking off at 6:30pm BST at the Ryan McBride Brandywell Stadium [6][7]. The first leg in Sofia ended 3–2 to CSKA Sofia, meaning Derry City needs at least a 2–1 win to force extra time or a higher scoreline to win outright [4][6].

Historically, teams facing a one-goal deficit in two-legged Europa League qualifiers often struggle to convert home advantage into a comeback, with many such fixtures ending in narrow home losses or draws that fail to overturn the aggregate [6]. In the July 9 first leg, CSKA Sofia dominated early odds at –565 and scored three goals in a high-scoring 3–2 result, suggesting their attacking form remains a reliable catalyst [3][5]. The current 0% YES price on Polymarket reflects this structural disadvantage, aligning with conditional token pricing that heavily discounts Derry City’s probability of winning the aggregate.

Traders should monitor pre-match squad announcements for Derry City, particularly any injuries to key attackers, and the official kick-off time confirmation on Polygon to ensure USDC settlement triggers correctly [7]. The over/under line for this leg is set at 2.5 goals, and given the 5-goal aggregate from the first leg, a high-scoring second match remains plausible [1][2]. Any late news on CSKA Sofia’s defensive lineup or weather conditions at Brandywell Stadium could shift on-chain liquidity before the 17:30 UTC settlement window closes.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
