Trusting StockX to verify sealed booster boxes?

They are smart. They are simply providing an option for people who are interested. Its an easy transition as they are the main authentication option for sneakers. It will most likely cater to newer collectors/cross collectors, which is a large demograph. They already have their own marketplace, and are valuated higher than any authentication entity in Pokemon. Even if every single E4 member doesn’t use their service, they won’t notice or care.
