Why this comparison matters in Canada
Polymarket and Sport Select / Proline+ represent two of the prominent prediction market options accessible to Canada investors in 2026. They differ on the dimensions that matter most: regulation (gray-market vs state), currency (USDC vs CAD), and the practical tax/compliance experience.
