Wes had this to say in his post from this link:

Revelation 6:1 - 3 states "I watched as the Lamb opened the first of the seven seals.  Then I heard one of the  four living  creatures say in a voice like thunder 'Come!'  I looked and there before me was a white horse!  Its rider held a bow and he was given a crown, and he rode out as a conqueror bent on conquest."  This is the AntiChrist who next is bent on conquest of the whole world.  He certainly will be known by the whole world at this time.  What follows is the death of 1/4 of the world's population by means of war, famine (which follows war), and plague.

The Bible does not say this rider is the AC. That is the reader's interpretation.
