The South Texas building spree by billionaire Elon Musk’s rocket company SpaceX appears to have outpaced its payments to roughly two-dozen contractors, Reuters reports. Companies that have done work for Boca Chica-based SpaceX have filed at least 72 liens since 2019 against sites built by the company and its affiliates, the wire service reports, based on a review of Texas property records. Those liens seek to cover more than $2.5 million in allegedly unpaid work.
