We present an all-sky 90\% confidence level upper limit on the cosmic flux of
relativistic magnetic monopoles using 2886 days of IceCube data. The analysis
was optimized for monopole speeds between 0.750$c$ and 0.995$c$, without any
explicit restriction on the monopole mass. We constrain the flux of
relativistic cosmic magnetic monopoles to a level below $2.0\times 10^{-19}
{\textrm{cm}}^{-2} {\textrm{s}}^{-1} {\textrm{sr}}^{-1}$ over the majority of
the targeted speed range. This result constitutes the most strict upper limit
to date for magnetic monopoles above the Cherenkov threshold and up to $\beta
\sim 0.995$ and fills the gap between existing limits on the cosmic flux of
non-relativistic and ultrarelativistic magnetic monopoles
