Osmosis is a spontaneous process because it leads to an increase in the entropy of the system. This means that the molecules of the solvent (e.g. water) become more disordered as they move from an area of lower concentration to an area of higher concentration, which is the direction that osmosis occurs. Additionally, osmosis does not involve any input of external energy, making it a passive transport process.
