Yeah I have heard about gambling sites doing this, but for prediction markets I dont think they can do that. But also how can they lock it before a home run happens unless they're just locking it on every at-bat and rejecting/holding bets if a HR happens? These prediction markets have APIs and work the same way as the stock market, there are sellers and buyers in the market so messing with that process would be explicitly unfair and probably illegal.
