Startup cost: $100 - $5k

Setup costs for starting a sports betting side hustle can range from $100 to $5,000. At the low end, the minimum investment might cover basic online platform fees, initial bets, and possibly some advertising budget. On the high end, the maximum investment could include premium betting tools, subscriptions to expert analysis services, marketing campaigns, and a more substantial bankroll for betting. Essential expenses include platform fees, initial betting funds, and basic analytical tools. Optional expenses may include premium betting tips services or advanced analytics software. Hidden costs may involve transaction fees for depositing and withdrawing funds. Online feedback suggests that while starting costs can be low, they may increase as one commits more seriously to the venture. If a friend wanted to take sports betting seriously, I would recommend budgeting between $100 to $5,000 to cover initial setup and operational expenses.
