That was because Trump's company claimed last year it had $9.5 billion in revenues. However, recent public filings made by Trump's own company revealed the actual revenue was less than one-tenth of their claim, or about $600 million to $700 million before expenses.
Hence, Crain's is now correctly reporting Trump's business is worth less than one tenth of what Trump was saying. This has caused Trump's business to be knocked far down in rankings; it was previously at the number three spot but is now way down at number forty.
This is so typical of Trump's style of dissembling and gross exaggeration. He can't achieve something legitimately, so he lies to make it look like he did.
