The right tool for each purpose
Understanding the cost difference
Australian bookmakers embed their margin (the "overround") directly into the odds. A market with true 50/50 probability would pay $2.00 at fair odds, but a bookmaker paying $1.85/$1.85 is taking an 8% margin. Polymarket's ~2% taker fee is applied on execution only: maker orders pay 0%. For high-volume traders, this difference compounds significantly.
