Several publicly traded Bitcoin miners are enjoying a significant revaluation of their stock prices after pivoting to AI infrastructure, but investors are increasingly questioning whether insiders and large shareholders capitalized on the rally before the sector cooled, raising new governance concerns, according to Broxbridge Consulting.
In its latest Miner Weekly newsletter, Blocksbridge said the AI narrative has helped lift the valuation of several Bitcoin mining companies as they reposition their businesses around data centers, power infrastructure, and partnerships with hyperscalers. However, sentiment subsequently weakened, and AI stocks and semiconductor stocks declined. The TEM AI Infrastructure Growth Index, which tracks Bitcoin miners, artificial intelligence cloud providers, power suppliers and other AI infrastructure companies, has fallen 16% over the past month.
This change has brought more attention to insider trading. Executives from TeraWulf, Cipher Digital, Riot Platforms and Core Scientific have disclosed stock sales, many of which were executed pursuant to pre-arranged Rule 10b5-1 trading plans. Such plans are common and designed to avoid disputes over non-public information, but the sale is attracting more attention as AI stocks have tumbled, Broxbridge said.
This trend extends beyond corporate executives. Strategic investors have also reduced their exposure, including stablecoin issuer Tether, which reduced its stake in BitDeer following its AI-driven recovery.
According to Blocksbridge, investors’ focus is increasingly shifting from the AI growth story to questions about governance and whether the benefits of technology transition will ultimately flow to public shareholders.

Blocksbridge said TeraWulf provides the clearest example because it remains one of the biggest beneficiaries of AI infrastructure migration. CEO Paul Prager and his company Beowulf E&D Holdings sold about 1.59 million shares of WULF stock before the company announced Monday a 20-year AI infrastructure lease agreement with AI developer Anthropic, a deal widely seen as a key validation of the company’s AI strategy.
Spending on AI raises questions about long-term benefits
Many Bitcoin miners are pivoting to AI data centers as the economics of mining become increasingly difficult, especially after the 2024 Bitcoin halving squeezes industry margins. But the artificial intelligence trade is also crowded, with companies facing increasing pressure from investors to justify large infrastructure investments amid uncertain returns.
A report published by Deloitte in October described AI as a “paradox of increased investment and elusive returns” and noted that many organizations expect their investments in AI to take longer than expected to generate meaningful value.
Another study by Teneo, based on a survey of more than 350 public company CEOs, found that less than half of artificial intelligence initiatives deliver benefits that exceed costs.

Despite these challenges, companies continue to invest aggressively in AI infrastructure and expect long-term demand for computing power to outweigh short-term concerns about profitability.
Bitcoin miners are poised to seize the opportunity because they have access to large-scale power and existing data center infrastructure.
