Kinda complicated but the main idea is you get 10 $100 bonus bets. For each one you need to first unlock it by betting $100 on some event (find something close to 50/50) and then hedge it on another app. Concretely let's say you bet $100 on the washington wizards to win, with a payout of $190. You'd bet $100 on their opponent (e.g. the golden state warriors) on kalshi for a payout of $190, so you're guaranteed to lose $10 - but, in return you unlock your bonus bet. Then, the bonus bet you should place on some binary event which is a long shot on fanatics: so on fanatics, bet on the underdog. Concretely you might bet the $100 bonus bet that 2026 Connor McGregor beats Max Holloway to win $550. Then, you hedge on a prediction market (feel free to use my kalshi referral code in this collection!), to win $550 (just adjust the numbers so that you win $550). As long as the odds are pretty similar between the two websites (highly likely for popular events, can send screenshots to chatgpt or something to verify), you'll extract something like $70 every time you do this 0 risk.

Not really sure how much the EV is on this (maybe just ~$10), but you need a prediction market to hedge to extract the other bonuses :)
