Bitcoin Miners’ AI Pivot Faces Scrutiny Over Insider Share Sales and Governance

Bitcoin miners previously rode the high-performance computing and AI boom, boosting their valuations by touting a shift into AI infrastructure. But as AI stocks have cooled recently, the high cost of the hardware needed for such transitions has come under scrutiny. Investment firm VanEck estimates that miners face a funding gap of nearly $50 billion. Investors are consequently taking a harder look at corporate governance, fearing that equity raises could dilute their holdings and trigger major pullbacks in stocks tied to the transition.

In early July 2026, the AI Infrastructure Growth Index tumbled about 16%. Around that time, TeraWulf CEO Paul Prager sold about 1.59 million shares before the company signed a 20-year lease with Anthropic, while Core Scientific’s chief legal officer also reported selling 140,000 shares in early July. The senior executives’ share sales near stock-price highs have fueled intense market concerns about corporate governance and insider trading.
