  Scalar dark matter (DM) in a theory introduces hierarchy problems, and
suffers from the inability to predict the preferred mass range for the DM. In a
WIMP-like minimal scalar DM set-up we show that the infinite derivative theory
can predict DM mass and its coupling. The scale of non-locality (M) in such a
theory in its lower-most limit (constrained by LHC) implies a DM mass $\sim$
TeV and a coupling with the Standard Model (SM) Higgs $\lambda_\mathrm{HS} \sim
10^{-2}$. Planned DM direct detection experiments reaching such sensitivity in
the DM will effectively translate into lower bounds on the scale at which the
non-locality comes into the play. Self-interactions of DM and its impact on
vacuum stability in this model are also discussed in the context.
