Owed a billion dollars in Nvidia stock

A Reddit user claims to have been owed a billion dollars in Nvidia stock after discovering a bug in a fantasy football app that simulated a stock market. The user, who goes by the username 'throwaway12345678', claims to have won the equivalent of $1 billion in Nvidia stock through the app's 'Nvidia Stock Narrative' feature. The bug allowed the user to repeatedly bet on the stock price increasing, essentially guaranteeing a win. The user claims to have cashed out $1.5 million in real money, but is now owed the remaining $998.5 million in Nvidia stock.
