Market context

The Los Angeles Angels face the Cleveland Guardians in an MLB regular-season matchup scheduled for 13 May at 1:10 PM ET. The current order book on Polymarket reflects a 42% implied probability for an Angels victory, with the Guardians priced at the inverse. This probability emerges from real-time trading activity and represents the aggregate assessment of market participants regarding each team's likelihood of winning the single game.

Historical matchups between these franchises provide context for evaluating the current pricing. The Angels and Guardians have competed across multiple seasons with varying competitive trajectories. The Guardians have demonstrated stronger recent performance, having contended for divisional titles in the AL Central, whilst the Angels have faced roster inconsistency and injury challenges in recent campaigns. Early-season form, pitching matchups, and home-field advantage typically drive single-game probabilities in baseball markets, with the Angels' home-field status at Angel Stadium offering some offsetting value against Cleveland's recent competitive strength.

Traders should monitor roster updates and injury reports through to settlement, particularly regarding starting pitcher assignments and key position player availability. Weather conditions at Angel Stadium on game day—notably temperature and wind patterns—can materially affect play in a ballpark known for variable conditions. Recent team performance trends, including win-loss records and run differential in the preceding week, often shift market probabilities as new information emerges. The settlement window extends to 20 May, providing time for any postponement or rescheduling to be resolved before final settlement against official MLB statistics.

Resolution source

This market settles from the official outcome published at https://www.mlb.com/. 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 "Los Angeles Angels vs. Cleveland Guardians" 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 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% 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?

$0 in lifetime turnover and $27K 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.

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.
