The Sixteen Thirty Fund alone spent $196 million on political causes including $66 million supporting liberal politicians and ballot initiatives. Swiss billionaire Hansjörg Wyss has contributed $245 million to Arabella entities since 2016, with $208 million going to the Sixteen Thirty Fund. The Atlantic called it 'the indisputable heavyweight of Democratic dark money,' noting it was the second-largest super-PAC donor in 2020. The network faced scrutiny in September 2022 when the D.C. attorney general issued subpoenas seeking information on alleged financial mismanagement.
