It maybe possible to construct a notion of infinite speed, but it will not be a relativistic speed as defined in special relativity. That is, it won't appear as a speed between co-moving inertial frames. Even then, infinity is something that cannot be measured and thus any infinite speed will not be something measurable. So maybe arbitrarily fast, but finite speed are better.

Wait, consider the vertex made by two straight edges, such as the edges of two sheets of paper. You can make the vertex move at infinite velocity if you choose the angle between the edges to be zero.

a few of you have mentioned that the speed of light is the universal speed limit this is true but this is actutally this is the universal speed limit of matter

because of this spacetime its self travels faster then the speed of light this is possible because spacetime has no mass so it can "travel" (truely it expands) faster then the speed of light breaking the speed barrier
