I will discuss critically a recent analysis that concluded that the prompt production rate of the X(3872) at the Tevatron is too large by orders of magnitude for this state to be a weakly-bound charm-meson molecule. I will point out that if charm-meson rescattering is properly taken into account, the upper bound is increased by orders of magnitude and is compatible with the observed production rate at the Tevatron. In the framework of NRQCD I will then discuss the differential cross section for production of the X(3872) at the Tevatron and the LHC from prompt QCD mechanisms. The results presented in this talk are based on the paper arXiv:0911.2016.
