  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.
