Colombia vs. Costa Rica - More Markets

Platform comparison

Active sub-markets

Market context

Colombia and Costa Rica will meet in a FIFA International Friendly on 1 June 2026 at 7:00 PM ET, with settlement contingent on whether additional derivative markets materialise on the host platform. The 100% implied probability reflects near-certainty that supplementary betting options—such as correct score, player props, or half-time/full-time combinations—will be offered once the fixture is confirmed and squad lists are published. Polymarket's binary structure and Kalshi's regulatory constraints create divergent pathways here: Kalshi typically restricts itself to binary yes/no outcomes on major sporting events, whilst Polymarket's decentralised model permits more granular market proliferation. Betfair and Smarkets, operating under established UK gambling licences, have historically launched 15–20 secondary markets per international friendly within 72 hours of team announcements, converting decimal odds across multiple bet types.

The settlement window closes 1 June at 23:00 UTC, allowing roughly 16 hours post-kick-off for market confirmation. Key catalysts include official FIFA fixture confirmation (expected by March 2026), squad announcements from both federations, and injury updates in the fortnight preceding the match. Colombia's recent Copa América and World Cup qualifying performances, alongside Costa Rica's CONCACAF Nations League standing, will influence whether platforms judge sufficient liquidity exists to justify secondary market creation. Fee structures matter here: Polymarket charges 2% on resolution, whilst Kalshi's flat-fee model may discourage low-volume niche markets. Smarkets' 5% commission and Betfair's tiered structure incentivise higher-turnover markets, explaining why friendlies between lower-ranked sides sometimes see delayed or cancelled secondary offerings on those platforms.

Methodology

We read Colombia vs. Costa Rica - More Markets from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Kalshi Alternative UK routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
