It is well‐known that not all instances of the stable roommates problem admit a stable matching. Here we establish the first nontrivial upper bound on the limiting behavior of P n , the probability that a random roommates instance of size n has a stable matching, namely, lim n →∞ P n ⩽ e 1/2 /2 (=0.8244…). © 1994 John Wiley & Sons, Inc.
