Pronóstico: Sparta Rotterdam vs. Feyenoord Rotterdam

Platform comparison

Market context

Sparta Rotterdam host Feyenoord Rotterdam in the Eredivisie, and the 2% YES price is being set against a long-run head-to-head that still favours Feyenoord heavily. Across the recent sequence, Feyenoord beat Sparta 4-0 in August 2025 and 3-0 in February 2025, but Sparta did spring a 4-3 away upset in January 2026, which is the main reason a tiny yes probability is not simply zero.[1][17] Over a broader sample, Sportradar’s historical record shows Feyenoord have won 36 of 47 meetings since 1993, with Sparta winning six and five draws, so the baseline read remains strongly pro-Feyenoord even before line-up news lands.[10]

The most relevant trading catalysts are the confirmed starting XIs, late injury updates and any benching of attacking regulars, because this fixture can move quickly if Sparta field a stronger transition side or Feyenoord rotate after a congested schedule. Sparta’s recent form in the sources is mixed rather than catastrophic, with Sky Sports listing a 0-4 loss to Excelsior on 17 May 2026 and earlier draws and defeats that suggest volatility rather than consistency.[14] For Feyenoord, the market will be most sensitive to whether they repeat the compact, control-heavy approach that delivered the 2025 wins or whether they leave space for Sparta’s counterattacks; live team pages and pre-match lineup feeds are the key dependency before kick-off.[2][4][15]

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
