The Vanity Fair article would be like me claiming that every single jackpot in Vegas last week was won by the same person. Without any supporting evidence of that assertion, or any explanation about how I came to this conclusion.

Then Bellagio just responds "Uhhh... No... That didn't happen."

Before demanding that Bellagio compromise the privacy of their customers to explicitly dis-prove it, maybe, just maybe the original journalists should provide some actual evidence. Something besides "Nah-ah. They totally were all the same person. Don't ask me how I know it. I just do."

The original article said that X contracts were traded by a single party right before the close, where X was actually the total number of contracts traded by all parties. So either Vanity Fair didn’t fact check their article or zero other people happened to trade during that time frame (which is as about likely as zero people deciding to go to the grocery store on a given day).

How do you prove a negative? Isn’t it on vanity fair to prove it versus speculating? This sounds like another Bloomberg

> If it’s patently false prove it.

Why? Just find someone you respect to explain it to you. The CME Group doesn't have to do anything here.

If something illegal happened let one of the enforcement agencies subpoena them.

That one sentence is sufficient to disprove the Vanity Fair article.

That's literally how bad that article was.
