"Anti-Christ" are those who deny Christ (I assume, despite having decent knowledge). Since Jews are waiting for their own messiah, and it's all interwoven with their NWO, I assume you mean that figure. I'm pretty sure some prominent Jews through history said they, collectively, are their own "Mashiach," that being said, they still need a kingly figurehead to fulfil all the Torah and Talmud prophecy requirements in order to legitimise their religious narrative to the world.
