For the Gov to come out and block a model for national security, its gonna swing the market into thinking "oh anthropic really has the next generation of LLMs out there, its that good Gov banned it, this company is going to the moon".
The part of banning non US nationals, I believe is a legality, as in they have to trust US citizens to do right by their country. I don't think in court a whole ban on a product for security reasons would stand. (The judge would ask for the gov to explain why all US nationals are a security threat to their country)
Nevertheless, again I am standing behind number 2 personally as the main reason for such a thing, market manipulation is not new and its currently at its all time high. Also anthropic is part of this manipulation so far, with every other AI company out there.
Again I am just presenting my POV, it could as well just be number 1... A gov became competent enough to find security threads before they happen :)
There are lots such products, like weapons-grade radioactive material, weapons outside the toy gun range, various biological material, ...
So it seems perfectly possible to bad products for security reasons.
It might be a good marketing trick but it is not a good thing in the stock market given historical trends.
Your view highly screams you only have a superficial understanding of financial markets and you shouldn't extraploate that to "this is how market works because its all hype and everything is vapor"
Anthropics reputation as a near-term world-ender boosts their IPO directly.
I feel you are just talking a hypothetical without having any basis. You think it'll have an impact on IPO directly and that it will be a positive one. But you have no proof or historical precidence for the same. Meanwhile we have historical proof that markets reacts negatively when a company is blocked by the government on selling their top products freely. And that is most likely going to happen here as well.
Public perception might be changed by these "ohhh its so scary guys" marketing but these don't translate to actual market perception when it comes to actual facts and numbers on the financials.
Now it’s a competition between products on the near frontier. Anthropic has executed well on products so far. They blew up thanks to Claude Code, not Opus by itself.
