h i g h l i g h t s • We provide an axiomatic characterization of Expected Scott-Suppes utility representation. • This can be used in applications that study intransitive indifference under uncertainty. • Our main result is the natural analog of vNM expected utility theorem for semiorders. • Our characterization provides an answer to the open problem noted by Fishburn (1968). • Our representation offers a decision-theoretical interpretation for epsilon equilibrium.
