  With the measurement of positron flux published recently by AMS-02
collaboration, we show how the leptophilic dark matter fits the observation. We
obtain the percentages of different products of dark matter annihilation that
can best describe the flux of high energy positrons observed by AMS. We show
that dark matter annihilates predominantly into $\tau\tau$ pair, while both
$ee$ and $\mu\mu$ final states should be less than $20\%$. When gauge boson
final states are included, the best branching ratio of needed $\tau\tau$ mode
reduces.
