SK Brann vs. Rosenborg BK - Exact Score

Platform comparison

Market context

SK Brann’s meeting with Rosenborg BK is a live Eliteserien exact-score market, and the 0% YES print is best read as an *extreme* market position rather than a literal statement that no listed scoreline can land. Historical data does not support that level of certainty: the sides drew 1-1 in April 2026, while Brann have won the last four league meetings listed by ESPN’s head-to-head log, including 3-2, 2-1 and 3-0 results; longer-run aggregates still show a relatively balanced rivalry, with FootyStats recording 11 Brann wins, 13 Rosenborg wins and five draws across 29 meetings[2][5][18]. That mix usually pushes exact-score contracts towards low-probability clusters such as 1-0, 1-1, 2-1 and 2-2, rather than any single dominant outcome.

For cross-platform comparison, the main point is that a prediction-market read of 0% is far below what the historical score distribution would normally imply for a fixture with repeated narrow margins and occasional draws[2][5][6]. Traders should watch the confirmed line-ups, because exact-score markets are highly sensitive to late attacker or goalkeeper changes, and any postponement or abandonment risk matters because the contract remains open until the match is completed under the stated settlement rules. The practical catalysts are simple: team news close to kick-off, pitch and weather updates in Bergen, and whether either side is already in a congested run of fixtures that might affect rotation.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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 Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within 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.
