GRIID Infrastructure Inc. was a U.S.-based vertically integrated Bitcoin mining company founded in 2018, focused on building, owning, and operating low-carbon powered data centers across states like Tennessee, New York, Ohio, and Texas. The company emphasized self-mining with efficient operations, long-term power contracts (e.g., TVA for expansions), and a pipeline exceeding 400 MW, primarily in Tennessee. GRIID went public via SPAC in late 2023. In June 2024, CleanSpark announced an all-stock acquisition of GRIID (enterprise value $155 million); the merger closed on October 30, 2024, after shareholder approval on October 28, 2024. GRIID became a wholly-owned subsidiary of CleanSpark (NASDAQ: CLSK), with its stock delisted shortly after. Assets, facilities, and operations (including Tennessee pipeline) are now integrated into CleanSpark's portfolio. As of December 22, 2025, GRIID is defunct as an independent entity.
