Is the claim true? Can they document the claim?
The discussion forum is full of perfect “success” stories. Not one negative story. Hmmm. 
AI generated?

Sure. They make 100 different predictions using various inputs. Wait a month or a year or whatever. Cherry pick the one that’s best, make an ad with it. Ignore the others.
I just watched a show saying that the Pepsi Challenge gave Pepsi a 51.2% “win”, but Pepsi’s advertising made it seem like it was some overwhelming preference.
It turns out that advertising can, sometimes, also be truthful, but not really that often.
This is still irrelevant. Because they can set up a million bots, let them each run for a month with simulated money. And then only use the best ones for their ads. The claim is absolutely true - THAT bot turned $1k into $50k.
There is no one involved. It is AI.
Document? We don’t compute no stink’n document.
You are making the assumption that this fly by night concept cares that much.
