Abstract: Axion dark matter thermalizes by gravitational self-interactions and forms a Bose-Einstein condensate.  It is shown that the rethermalization of the axion fluid during the initial collapse of large scale overdensities at cosmic dawn transports angular momentum outward sufficiently fast  that black holes form with masses ranging from approximately $10^5$ to a few times $10^{10}$ $M_⊙$
