For a universe presently dominated by static or dynamic vacuum energy, cosmological constant (LCDM) or quintessence (QCDM), we calculate the asymptotic collapsed mass fraction as function of the present ratio of vacuum energy to clustered mass, \Omega_{Q0}/\Omega_{m0}. Identifying these collapsed fractions as anthropic probabilities, we find the value \Omega_{Q0}/\Omega_{m0} \sim 2 to be reasonably likely in LCDM, and very likely in QCDM.
