Trade: US Catanzaro 1929 vs. US Avellino 1912 - Exact Score

Market context

US Catanzaro 1929 and US Avellino 1912 meet in Serie B on 12 May 2026 at 15:00 ET. The market prices an exact final score at 7% implied probability across Polymarket's order book, reflecting the substantial difficulty of predicting a precise scoreline in professional football. Settlement depends on the 90-minute result plus stoppage time only; any other outcome resolves to "Any Other Score."

Exact-score markets in football typically carry low probabilities because they require both teams' final tallies to match a single discrete outcome. Historical Serie B fixtures show that the most common scorelines—1–0, 1–1, 2–1—occur in roughly 10–15% of matches individually. The 7% current probability suggests traders are pricing this particular match outcome as less likely than a typical Serie B fixture, possibly reflecting squad composition, recent form, or head-to-head patterns between these clubs. Polymarket's order book depth will determine whether this probability tightens or widens as the fixture approaches.

Key variables affecting the outcome include team news and injury status in the weeks preceding the match, managerial tactical adjustments, and any fixture congestion affecting player availability. Serie B scheduling announcements and official team sheets released closer to 12 May will provide concrete information. Traders should monitor both clubs' recent goal-scoring patterns and defensive records, as these directly influence which scorelines remain plausible. The market remains open until the match concludes; postponements would extend the settlement window rather than trigger early resolution.

Resolution source

This market settles from the official outcome published at https://www.legaserieb.it/. 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 active is this market?

$0 in lifetime turnover and $26K 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.
