Several publicly traded Bitcoin miners have benefited from strong stock market revaluations after pivoting to AI infrastructure, but investors are increasingly questioning whether insiders and major shareholders took advantage of the rally before the sector cooled, raising new governance concerns, according to Blocksbridge Consulting.
In his latest Miner Weekly newsletterBlocksbridge said the AI narrative has helped boost the valuations of several Bitcoin mining companies as they reposition their operations around data centers, power infrastructure and hyperscaler partnerships. However, sentiment has since weakened, with AI and chip stocks retreating. The TEM AI Infrastructure Growth Index, which tracks Bitcoin miners, artificial intelligence cloud providers, energy providers and other AI infrastructure companies, is down 16% over the past month.
This change placed more emphasis on insider transactions. Executives from TeraWulf, Cipher Digital, Riot Platforms and Core Scientific disclosed stock sales, many of which were executed under pre-established Rule 10b5-1 trading plans. While such plans are common and designed to avoid conflicts over non-public information, the sales have come under greater scrutiny as AI-related stocks have retreated, Blocksbridge said.
The trend extends beyond business leaders. Strategic investors have also reduced their exposure, including stablecoin issuer Tether, which reduced its stake in Bitdeer after the company’s AI-driven rebound.
According to Blocksbridge, investors are increasingly shifting their attention from the conversation about AI growth to questions of governance and whether the benefits of the technology transition will ultimately accrue to public shareholders.

Blocksbridge said TeraWulf offers the clearest example as the company remains one of the biggest beneficiaries of the AI infrastructure transition. CEO Paul Prager and Beowulf E&D Holdings, an entity he leads, sold about 1.59 million WULF shares before the company announced Monday a 20-year AI infrastructure lease with AI developer Anthropic, a deal widely seen as a major validation of its AI strategy.

AI spending raises questions about long-term returns
Many Bitcoin miners have pivoted to AI data centers as the mining economy has become increasingly difficult, especially after the 2024 Bitcoin halving squeezed industry margins. However, the artificial intelligence market has also become more saturated, with companies facing increasing pressure from investors to justify heavy infrastructure spending amid uncertain returns.
A report published Deloitte described AI in October as a “paradox of increasing investments and elusive returns,” noting that many organizations expect investments in AI to take longer than expected to generate significant value.
Separated research by Teneo, based on a survey of more than 350 public company CEOs, found that less than half of artificial intelligence initiatives generated returns greater than their costs.

Despite these challenges, companies continue to invest aggressively in AI infrastructure, betting that long-term demand for computing capacity will outweigh short-term concerns about profitability.
Bitcoin miners, with access to large-scale energy and existing data center infrastructure, are positioning themselves to seize this opportunity.
