Ceará SC vs. Athletic Club - More Markets

Platform comparison

Market context

Ceará SC will travel to face Athletic Club in a Serie B fixture on 13 July at 19:30 ET, with the current market pricing this outcome at 0% implied probability. This represents an extreme consensus against additional markets materialising for the match, rather than a reflection of either team's likelihood of victory in the underlying contest.

The 0% reading sits at the tail end of prediction market behaviour for secondary sports events. Serie B matches, whilst lower-profile than the top division, regularly attract supplementary betting markets once fixture details confirm and team sheets emerge. Historical patterns show that markets for Brazilian second-tier games typically expand 48–72 hours before kick-off, particularly when both clubs have established supporter bases willing to back niche propositions. The current zero valuation suggests either minimal anticipated liquidity for ancillary markets or a technical settlement definition that excludes standard secondary offerings.

Traders should monitor official team announcements and injury bulletins from both clubs, which typically arrive mid-week for weekend fixtures. The timing of this match—scheduled for a Monday evening in the middle of the season—may affect market depth compared to weekend slots. Ceará and Athletic Club's respective league positions and recent form could influence whether bookmakers and prediction platforms deem secondary markets commercially viable. Any significant roster changes or managerial developments would likely trigger broader market activation, though the current zero probability suggests the consensus expects minimal secondary market development for this particular fixture.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
