This depends upon your definition of a portal. Portals currently exist when they refer to a video game developed by Valve. They can also refer to a "gateway", as in a website that can lead you in many different directions. There could be a portal that takes you to a group of URLs for restaurants, or one for leisure activities.
However, if you mean a portal that allows physical matter to be transported elsewhere, scientists are actually very close to doing that with extremely small particles.
If you are referring to the capability of transporting a human from one place to another, it is going to take quite a while to develop that technology, at least the ability to do it safely!
