Blair Hull is a former professional blackjack player who transitioned into a highly successful career in finance. He was part of the first wave of card counters who took casinos for significant sums in the 1970s. Later, he applied his mathematical skills to options trading, eventually founding Hull Trading Company, which he sold for hundreds of millions of dollars. Hull’s story is an example of how gambling skills — probability, risk management, bankroll discipline — can translate into success in other high-stakes industries.
