For a P 1-orbifold C, we prove that its big quantum cohomology is generically semisimple. As a corollary, we verify a conjecture of Dubrovin for orbi-curves. We also show that the small quantum cohomology of C is generically semisimple iff C is Fano, ie it has positive orbifold Euler characteristic.
