- Bitcoin miners that repositioned around AI data centers and hyperscaler partnerships enjoyed sharp stock re-ratings, but the TEM AI Infrastructure Growth Index has fallen 16% over the past month as insider transactions drew renewed governance scrutiny from Blocksbridge Consulting.
- TeraWulf CEO Paul Prager and Beowulf E&D Holdings sold roughly 1.59 million WULF shares shortly before the company announced a 20-year AI infrastructure lease with Anthropic, a deal Blocksbridge called the clearest case study of insider timing.
- Cipher Digital executives disclosed stock sales alongside peers at Riot Platforms and Core Scientific, with many transactions executed under prearranged Rule 10b5-1 trading plans as AI-related stocks retreated.
- Stablecoin issuer Tether trimmed its stake in Bitdeer after the miner's AI-driven rebound, extending the selling trend beyond company insiders to strategic investors.
- Deloitte described AI as a "paradox of rising investment and elusive returns," and a Teneo survey of 350-plus public company CEOs found fewer than half of AI initiatives have delivered returns exceeding their costs.
- Bitcoin's 2024 halving squeezed mining margins, accelerating the pivot by operators with existing power and data center capacity toward AI compute leases even as investor skepticism over long-term AI returns grows.
Why it matters: TeraWulf's CEO offloaded 1.59 million shares days before unveiling its flagship Anthropic lease — exactly the timing pattern that turns an AI infrastructure story into a governance one. With the TEM AI Infrastructure Growth Index down 16% in a month and Deloitte framing AI as a "paradox of rising investment and elusive returns," retail shareholders are now the ones holding bags the insiders appear to have already exited.
