Reasoning
Standard MLB season outright market (World Series winner). Domain: sports. Outcome is binary (Rockies win or do not win). Resolution date aligns with end of 2026 MLB season. Pinnacle regularly offers season-long championship outrights for all MLB teams. Expected match class A: identical quantitative outcome, same resolution source (official MLB), standard resolution date for World Series completion.
