They used to have a huge markup some 15 years ago. No longer. It's hard to determine price of a crewed Soyuz mission, but an unmanned Proton rocket, when ordered to launch Russian military satellites (which obviously can't bear much markup because it is the parts of the same system buying from each other, large markup only means increasing taxes) is 1.5x the price of a Falcon 9 launch, with a low orbit payload about 1.5x Falcon's and GEO orbit payload about 1.1x Falcon's. So any and all price advantage Russian rockets used to have over American is now eroded due to increased salaries (an aerospace engineer got about $500-$1000 a year 15 years ago and about $10K a year now) and lower SpaceX prices.
