Ultimately, if you piss off the IBM execs enough (which is what Palantir is exceptionally good at), then IBM will mobilize a significant chunk of the company to obliterate anything in its wake. Even if that means making a huge loss.
They then try to use that win as a template for future success. Unfortunately IBM is incapable at that since the harsh reality is its software division is just a bunch of incoherent acquisitions who can't generally collaborate.
