I'm curious if going public would lead to more transparency about what they do and for whom. Enron was famously opaque to its own investors until it was too late, but I would hope that public companies have greater requirements for transparency nowadays.
I don't think that Palantir being a public company would necessarily give the kind of insight into what they do to satisfy our curiosity. As far as I understand, Palantir could be very financially transparent while still keeping mum about who their clients are and what they are doing for them.
I think it's worth remembering that Enron was public.
I agree with you on the whole, but Enron was pre Sarbanes-Oxley which initiated a raft of reporting requirements on companies, so Enron is often a poor comparison to the present day.
If you mean anything more specific than "we do stuff for the government we can't tell you about", probably not. Look at Boeing, Northop-Grumman, Booz Allen Hamilton, etc.
Hell, for that matter, look at AT&T, Verizon, and Level3 -- the companies that we didn't really expect to be doing the kinds of things they were doing.
That was my response as well. Going public means filing 10K statements which will lay all their business dealings out. Something I wouldn't think they or their clients would be interested in.
