• Are executives running first?

• Why miners are moving to AI?

In its latest Miner Weekly newsletter, Blocksbridge Consulting said that after AI transitions, several listed mining firms enjoyed a stock-price re-rating, but executive insider selling and governance issues are now coming to light.

Tracking the TEM AI infrastructure growth index for Bitcoin mining firms, AI cloud providers, and power suppliers, it fell 16% over the past month.

Are executives running first?

Several major mining firms’ executives have already disclosed share-selling moves, mostly carried out through the preset 10b5-1 trading plans:

• TeraWulf: CEO Paul Prager and related entities sold about 1.59 million shares of WULF before announcing a 20-year AI infrastructure lease with Anthropic
• Cipher Digital, Riot Platforms, Core Scientific: all have records of executives selling shares

Not only executives—strategic investors are also cutting exposure. After an AI rebound, stablecoin giant Tether at Bitdeer also reduced its holdings.

The “paradox” of AI investment returns

Deloitte’s October report describes an AI “paradox” of “rising investment, invisible returns,” where many organizations expect AI investment to take longer than anticipated to produce real value.

A Teneo survey of CEOs at more than 350 publicly listed companies also found that less than half of AI plans generate returns above cost.

Why miners are moving to AI?

After Bitcoin’s 2024 halving squeezed industry profits, economic pressure on mining firms has increased. Mining firms with large-scale power and existing data-center infrastructure are naturally positioned to pivot:

• Power capacity: miners are typically already connected to high-voltage grids
• Infrastructure: substations, cooling systems, and data-center sites
• Geographic advantages: many are located in regions with low electricity costs

Even so, CoinShares estimates that infrastructure costs per MW at mining sites are about $700k to $1 million, while liquid-cooled AI infrastructure requires $8 million to $15 million per MW—the transition isn’t a “no-spend” crossover.
