Market context
Como 1907 and Parma Calcio 1913 are scheduled to meet in Serie A on 17 May at 09:00 ET. The market is pricing a 55% probability for additional markets to be created around this fixture, with that probability derived from current order book activity on Polymarket. Settlement occurs at 13:00 UTC the same day, giving traders a four-hour window after kick-off to assess whether supplementary betting or information markets have been launched.
Historical precedent suggests that mid-table Serie A fixtures attract secondary markets primarily when broader narrative interest exists—promotion races, relegation scraps, or significant player movements. Como's recent return to the top flight and Parma's established presence create moderate conditions for ancillary market creation. Comparable May-fixture markets in prior seasons have settled YES roughly 60–65% of the time when the underlying match carried competitive weight, though the threshold for "more markets" varies by platform activity and trader demand at settlement time.
Traders should monitor team news and injury updates in the week preceding the match, as significant absences can shift speculative interest. Polymarket's order book depth will signal whether early traders expect supplementary markets; thin order books typically correlate with lower settlement probabilities. The fixture's position in the final Serie A matchday may also influence whether additional markets materialise, depending on whether either side has unresolved competitive objectives at that stage.

How active is this market?
$846 in lifetime turnover and $181K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $846 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 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.
