  The observation of many unexpected states decaying into heavy quarkonia has
challenged the usual QQbar interpretation. One of the most studied exotic
states, the X(3872), happens to be copiously produced in high-energy hadron
collisions. We discuss how this large prompt production cross-section disfavors
a loosely-bound molecule interpretation for this particle. This is supported by
Monte Carlo simulations, and by a comparison with extrapolated light nuclei
data by ALICE.
