Description
Santos FC and Fluminense FC are scheduled to compete on April 19, 2026, in a Brazilian Serie A match. Three mutually exclusive outcomes are being tracked: a Santos victory, a Fluminense victory, or a draw. Settlement will be based on the final score within 90 minutes of regular play plus stoppage time, with official CBF statistics as the primary source.

Divergence Detected
Issue:
Polymarket offers three mutually exclusive binary outcomes (Santos win, Draw, Fluminense win), while Kalshi offers four independent spread-based markets (Santos >2.5, Santos >1.5, Fluminense >1.5, Fluminense >2.5). The platforms measure different settlement dimensions: Polymarket resolves on match outcome only, Kalshi resolves on margin of victory.Hero Tip:
On Polymarket, exactly one of the three markets will resolve YES—they are mutually exclusive. On Kalshi, multiple markets can resolve YES simultaneously (e.g., if Santos wins 3-0, both 'Santos >2.5' and 'Santos >1.5' resolve YES). Do not assume Kalshi markets are mutually exclusive; they are independent spread bets. If you want pure outcome exposure, use Polymarket; if you want margin exposure, use Kalshi.Critical Divergence Points:
- Polymarket: Three binary outcome markets covering all possible results: Santos win (YES/NO), Draw (YES/NO), Fluminense win (YES/NO). Exactly one resolves YES. Scope: 90 minutes plus stoppage time only. Resolution source: official CBF statistics or credible reporting consensus within 2 hours. Cancellation with no makeup resolves Santos and Fluminense markets to NO, Draw market to YES.
- Kalshi: Four independent spread-based markets: Fluminense >2.5 goals, Santos >1.5 goals, Fluminense >1.5 goals, Santos >2.5 goals. Each market resolves YES or NO independently based on final margin. Scope: 90 minutes plus stoppage time only (no extra time or penalties). Multiple markets can resolve YES in the same match (e.g., Santos wins 3-0 triggers both Santos >2.5 and Santos >1.5).
