IK Start vs. Fredrikstad FK

Platform comparison

Market context

IK Start hosting Fredrikstad FK in Eliteserien, the market’s 0% YES price is hard to read literally, because exchange-style books normally quote outcomes as decimal odds or implied probability rather than an absolute “yes” stamp, and the same fixture can look different once fees and account access are factored in. Fredrikstad have had the better of the recent head-to-head, winning 2-1 in May 2026, and the broader sample also leans their way: across the last 11 meetings, Fredrikstad have 5 wins to Start’s 2, with 4 draws[1][2][3].

That history matters because these sides have often played tight, low-margin games, so a very low crowd-implied probability can reflect either a genuine mismatch or a data artefact if liquidity is thin. On Betfair, the market is closer to a pure exchange price with commission applied after the fact, while Smarkets and some other platforms present prices that translate into implied probability after fees; Polymarket-style markets also depend heavily on who can trade and how easily, with KYC reach varying by venue. For a trader, the important catalyst is late team news: confirmed line-ups, injuries, and any schedule congestion or rotation around summer fixtures can move a near-kickoff football market sharply, especially when the pre-match price is already extreme[9][10][11].
