Alex Jones has filed for bankruptcy, less than two months after a jury ordered him and the parent company of his Infowars website to pay nearly $US1 billion ($1.48 billion) in damages to relatives of the Sandy Hook mass shooting. 

Key points:

• A court filing showed that Mr Jones had between $US1 million and $US10 million of assets and between $US1 billion and $US10 billion of liabilities
• Mr Jones was ordered to pay compensatory damages after claiming the 2012 Sandy Hook shooting was staged
• A judge had temporarily blocked Mr Jones's assets at request of the plaintiffs, who claimed he was trying to avoid paying

Mr Jones filed for Chapter 11 protection from creditors with the US bankruptcy court in Houston, a court filing showed.

The filing said Mr Jones had between $US1 million and $US10 million of assets and between $US1 billion and $US10 billion of liabilities.

It also refers to Free Speech Systems, a Jones affiliate and Infowars' parent, as having filed for bankruptcy in July.

Jones acknowledged the filing on his Infowars broadcast, saying the case would prove he is broke and asking viewers to shop on his website to help keep the show on the air.
