Trade: FK Septemvri Sofia vs. FK Spartak 1918 Varna - Exact Score

Market context

FK Septemvri Sofia will host FK Spartak 1918 Varna in Bulgaria's top division on 14 May 2026, with the market settling on the exact final score after 90 minutes plus stoppage time. The 8% implied probability currently reflected on Polymarket's order book suggests traders assess a specific scoreline as unlikely, though the market structure allows for multiple outcomes to resolve as "Any Other Score" if the result falls outside explicitly listed possibilities. This concentration of probability mass indicates either a heavily favoured outcome among listed options or genuine uncertainty being priced into the broader market.

Historical patterns in Bulgarian Parva Liga matches show that exact-score markets typically see low individual probabilities for any single result, as football produces a wide distribution of outcomes. Septemvri Sofia and Spartak Varna occupy different positions in the league hierarchy, which shapes expected goal differentials. Septemvri Sofia has competed at varying levels of Bulgarian football, whilst Spartak Varna has established itself as a mid-table side in recent seasons. The 8% probability suggests traders are pricing in either a narrow scoreline or a less common result, depending on which specific outcome the market is tracking.

Traders should monitor team news, injury reports, and any fixture schedule changes before settlement. Recent form data and head-to-head records between these sides will influence how the order book reprices as match day approaches. The early morning kickoff time (8:15 AM ET) may affect liquidity patterns on Polymarket, particularly for European traders operating during their morning hours.

How active is this market?

$0 in lifetime turnover and $24K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.

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.
