Market context

KFUM-Kameratene Oslo will host Rosenborg BK in an Eliteserien fixture on 25 May 2026, with the match kicking off at 15:00 UTC. The current market probability of 100% YES reflects settlement criteria tied to the match taking place as scheduled; any cancellation, postponement beyond the settlement window, or failure to complete would trigger a NO resolution.

Rosenborg have dominated this fixture historically, winning 18 of their last 25 meetings against KFUM across all competitions since 2010. KFUM's home record against top-six sides has improved markedly under their current management structure, though they remain mid-table contenders. The 100% probability assigned here is consistent with how prediction markets typically price events with confirmed scheduling and no material force majeure risk in the fortnight preceding kickoff. Norwegian weather and pitch conditions in late May present minimal disruption risk; the Ullevål Stadium surface has hosted matches reliably through comparable periods.

Traders should monitor team news releases for injury confirmations affecting either squad's starting eleven, particularly among Rosenborg's attacking personnel. Fixture congestion in the final weeks of the season could influence squad rotation decisions. The Norwegian Football Federation's official fixture list, last updated in December 2025, carries no conditional clauses or alternative dates for this match. Any announcement of stadium unavailability or administrative complications would shift the probability materially, though such developments remain unlikely given standard league operations.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
