Following last year’s Bitcoin halving, which cut mining rewards in half, miners like Core Scientific have explored new revenue sources, including offering HPC services to AI and other compute-heavy firms.
Following the news, CoreWeave unveiled its filing for an initial public offering. The filing stated that the firm seeks to raise $4 billion at a $35 billion valuation.
