In this article it is shown that for almost every random cube process the hitting time of a complete matching equals the hitting time of having minimal degree (at least) one and also the hitting time of connectedness. It follows from this that if t = ( n + c + o (1))2 n −2 for some constant c , then the probability that a random subgraph of the n ‐cube having precisely t edges has a complete matching tends to e − e −e −c.
