Blackstone Investment is worth $1 billion, but the company has lost some of its valuation, according to analysts at Bank of America Merrill Lynch.
The investment firm has been losing money on investments since the election of President Donald Trump.
Blackstone has lost about $1.5 billion since last year, and analysts expect that to drop to $500 million this year, according the analysts.
Blackwater founder Erik Prince, who is also the son of late Blackstone CEO Steve, has been accused of orchestrating a plot to overthrow the Trump administration in an attempt to seize control of the oil company.
The New York Times reported last week that Prince, in a meeting with White House officials, told them that his son was plotting to overthrow Trump.
