  • The Cigarette Smoking Man.

    In Season 9 episode William (2002) it would appear Jeffrey Spender's DNA is so similar to Mulder's that he was nearly mistaken for Mulder - Scully readily accepts this and postulates that Spender knew their DNA would be similar at first glance. This implies they are siblings. Jeffrey's mother, Cassandra, states that Cigarette Smoking Man is Jeffrey's father. Jeffrey Spender later testifies at Mulder's trial in "The Truth (2002) that they are half-brothers as a result of an affair between Jeffrey's father (Cigarette Smoking Man) and Mulder's mom (Mrs. Mulder).

    Also in The Sixth Extinction II: Amor Fati (1999) both CSM and Diana Fowley refer to Mulder as CSM's son.

  • It certainly appears so, though there still exists some doubt.

    In the episode #9.19, The Truth, Scully confesses to Mulder that she "gave up our son" referring to hers and Mulder's.

    On the X-Files page of the Sci-Fi website, there are Syndicate reports on Mulder and Scully that describe how William was conceived and who his father is. The reports say that William was created from genetic material harvested from Mulder and Scully.

    The answer is in The X-Files I Want to Believe movie, and it's positive. Mulder is William's father.
