Marathon Digital Holdings has announced that 50% of its mining machine orders for 2025 will be sourced from Auradin, a US-based Bitcoin chip designer and manufacturer. This strategic partnership highlights Marathon's commitment to supporting domestic suppliers amid increasing tariffs on Chinese imports. Auradin, which began shipping its Teraflux series of Bitcoin ASICs in mid-2024, offers a US-made alternative to major Chinese manufacturers like Bitmain and Shenma. The company has seen a surge in demand from US mining firms following the imposition of new tariffs by President Trump in April.
