- TEM AI Infrastructure Growth Index, which tracks Bitcoin miners and AI infrastructure companies, fell 16% over the past month as AI and chip stocks pulled back, according to Blocksbridge Consulting.
- TeraWulf CEO Paul Prager and Beowulf E&D Holdings, an entity he manages, sold roughly 1.59 million WULF shares before the company announced a 20-year AI infrastructure lease with Anthropic on Monday.
- Executives at Cipher Digital, Riot Platforms, and Core Scientific also disclosed stock sales, many executed under prearranged Rule 10b5-1 trading plans that drew heightened scrutiny as AI-related stocks retreated.
- Tether trimmed its stake in Bitdeer after the company's AI-driven rebound, extending the insider selling trend beyond company executives to strategic investors.
- Bitcoin miners pivoted to AI data centers because mining economics became increasingly challenging after Bitcoin's 2024 halving squeezed industry margins, Blocksbridge said.
- Deloitte described AI as a 'paradox of rising investment and elusive returns,' while a Teneo survey of 350+ public-company CEOs found fewer than half of AI initiatives delivered returns exceeding their costs.
Why it matters: The TeraWulf timing is the sharpest data point: the CEO sold ~1.59 million shares before announcing a 20-year AI infrastructure lease with Anthropic, a deal that validates the company's AI strategy but now raises questions about whether insiders anticipated it. With the sector index down 16% in a month, governance scrutiny on Rule 10b5-1 plan sales at TeraWulf, Cipher Digital, Riot Platforms, and Core Scientific intensifies just as investors shift focus from growth narrative to whether public shareholders will actually capture the AI transition's value.
