Spain vs. Belgium - First Team to Score

Platform comparison

Market context

Spain and Belgium meet in a FIFA World Cup semi-final on 10 July 2026, with Spain favoured to strike first. The crowd-implied probability sits at 66% for Spain scoring first, reflecting their status as the clear favourite against a Belgium side that has conceded more frequently in recent tournaments. Historically, Spain dominates this fixture: across seven meetings since 1986, they have won six, scoring 16 goals to Belgium’s three, with an average of 2.3 goals per game [4]. In their two World Cup encounters, Spain holds one win and one draw, never losing [2]. Their most recent meeting saw Spain score six goals in a commanding victory, underscoring their offensive superiority [6]. This historical weight supports the 66% pricing, though the margin may be thin if Belgium’s attack, which has netted 13 goals in the tournament versus Spain’s nine, finds early rhythm [9].

Traders should monitor pre-match line-ups and tactical announcements, particularly whether Spain deploy an aggressive high press or a more controlled buildup. Spain’s defensive record is notable—they have conceded zero goals in their last five matches, a trend that could delay Belgium’s first strike [8]. Belgium’s reliance on long-range opportunities and counter-attacks may be key; if Spain’s midfield dominates early possession, the value in backing Spain first to score strengthens. Conversely, if Belgium’s forwards like Lukaku or Trossard start strongly, the contrarian angle on Belgium gains traction. No major injury news has emerged as of this morning, but late squad updates before the 3:00 PM ET kickoff could shift momentum [3]. The settlement window closes at 19:00 UTC, so all pre-game catalysts must be weighed before the final odds lock.

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.
