I wouldn’t put anything past them, but my impression is that they were just acting as a middleman for this transaction and taking a fee, rather than making a directional bet one way or another. Hedge funds have certainly been buying a lot of tariff claims, giving businesses guaranteed money upfront and betting on this outcome. But for an investment bank like Cantor Fitzgerald that would be atypical.
It’s not really excusing anything, just pointing out that Cantor Fitzgerald would be making money whether this Supreme Court ruling went for or against the Trump tariffs. So it’s not like they had to have any inside knowledge to be making money.
Ah yes, instead of applying the normal legal standard of “not even having the appearance of impropriety” we instead apply the monkey’s paw standard of waiting until they “no longer even have the appearance of propriety”.
