Philadelphia Phillies vs. Boston Red Sox

Platform comparison

Market context

The Philadelphia Phillies travel to Boston for a regular-season matchup against the Red Sox on 13 May at 6:45 PM ET. This market settles based on the official final result, with provisions for postponement (market remains open until completion) and cancellation or ties (50-50 split). The settlement window closes on 20 May at 22:45 UTC, allowing roughly a week for the game to be played and official statistics confirmed.

The 0% implied probability reflects minimal trading activity rather than certainty of outcome. Comparable MLB matchups at this stage of the season typically show book depth concentrated on markets with higher liquidity and established deposit flows. Markets with thin order books often display extreme probabilities until meaningful capital enters through accessible payment rails—whether SEPA transfers, USDC settlement, or Klarna-facilitated deposits. The absence of backing bets on either side suggests traders have not yet committed funds to this particular fixture, a common pattern for mid-May regular-season games with lower perceived edge.

Key variables include roster availability and recent form. The Phillies' 2025 performance trajectory and any injury updates to core players will influence pre-game positioning. Boston's pitching rotation and recent offensive metrics against comparable opponents provide concrete data points. Market depth typically increases as game time approaches and traders with deposited capital begin sizing positions. Monitoring whether major sportsbooks adjust their lines in the days before 13 May can signal where informed money is flowing, potentially triggering secondary liquidity in prediction markets once withdrawal infrastructure becomes active.

FAQ

How does Klarna deposit work on PolyGram?

You enter the deposit amount in EUR/GBP, choose Klarna as the method, run through Klarna's standard authentication (Pay Later or Direct Bank Transfer), and PolyGram converts internally to USDC for the Polymarket order book. Processing: typically under 30 minutes.

What does SOFORT cost as a deposit method?

PolyGram charges no fees for SOFORT. The only cost is the internal FX spread (typically <1%) on EUR→USDC conversion. SOFORT itself has no end-user fees — the platform absorbs acquirer costs.

Which payment methods are supported?

Klarna (Pay Now / Pay Later), SOFORT, SEPA bank transfer, credit card (Visa/Mastercard), Apple Pay, Google Pay, and direct USDC deposit on Polygon. Availability depends on your jurisdiction.

How do withdrawals work?

Identical methods in reverse. SEPA withdrawal: T+1 (standard) or under 10 seconds (SEPA Instant). Klarna withdrawals process via bank-account refund. USDC withdrawal to external wallet: Polygon gas cost (typically $0.01).

Are payment details protected?

Yes. Card and bank details are never stored by PolyGram — they pass directly through PCI-DSS compliant payment service providers (Adyen, Stripe). PolyGram retains only transaction IDs and Klarna reference numbers for reconciliation.
