Mr. Bannon earned at least $1.3 million and perhaps as much as $2.3 million last year, according to the disclosure report.

He disclosed $191,000 in consulting fees he earned from Breitbart News Network, the conservative media organization; $125,333 from Cambridge Analytica, a data firm that worked for the Trump campaign; and $61,539 in salary from the Government Accountability Institute, a conservative nonprofit organization. All three organizations are backed by the major Republican donors Robert Mercer and his daughter, Rebekah.

Mr. Bannon’s most valuable asset was Bannon Strategic Advisors Inc., a privately held consulting firm from which income from his other investments appeared to flow into. It was valued at $5 million to $25 million.

He also listed the value of his Bannon Film Industries at $1 million to $5 million. His bank accounts were valued at as much as $2,250,000, while he listed rental real estate valued at as much as $10.5 million.

Mr. Bannon made clear in his disclosure report that he intended to sell some of his assets, including his stake in Cambridge Analytica, the political consulting firm that sells “psychographic” profiles that it asserts can predict the personality and hidden political leanings of every American adult.

Mr. Bannon served until last summer as vice president of Cambridge’s board.
