Calculations of the minimum pressure in the M87 jet show that the jet pressure is an order of magnitude in excess of the thermal pressure in the interstellar medium calculated from the X-ray emission. The continuous energy input required to produce the jet emission is incompatible with a freely expanding jet. On the other hand, the uniform jet expansion, the jet emission and the jet polarization can be explained if the jet is self-confined by j x B forces.
