Blocksbridge Analysis: A $50 Billion Funding Gap
According to Blocksbridge Consulting’s recent analysis in the Miner Weekly newsletter, the entire mining-industry sector needs to invest about $50 billion to achieve its lofty AI transition goal; among them, IREN has the largest funding gap at approximately $21.1 billion.
Blocksbridge also noted that while the AI boom has driven a re-pricing of miner-stock valuations, it has also sparked investor attention on insider selling: profit-taking by executives at TeraWulf, Riot Platforms, Core Scientific, and Cipher Mining has led the market to question whether the AI narrative will push share prices to the same extent that management cashes out.
