I've never quite understood what's supposed to be so mind-blowing about the assassination market concept. I think the concept is supposed to be that assigning legal responsibility for such a killing would be difficult, since no one is literally paying an assassin.
But surely the answer is just that governments can and should ban prediction markets that are deemed to directly incentivize a crime. Where exactly to draw the line is challenging, sure, but no more challenging than all the other stuff that legal systems have to deal with. After all, pretty much any existing market (like stock markets) could be influenced by murdering certain people.
You may say "oh, but assassination markets are unique in that they're hard to ban those markets because they use cryptocurrencies and other decentralized/anonymous/censorship-resistant communication technologies." Well, okay, but if those technologies are so effective than people can already just run normal murder-for-pay markets.
