The 2024 Bitcoin halving cut block rewards from 6.25 to 3.125 BTC, compressing margins for miners. In response, many are pivoting to AI hosting, where demand for electricity and cooling is soaring. That shift is reshaping how the market values mining stocks — less on hashrate, more on megawatts and interconnection rights.
The Halving Squeeze
When block rewards fell by half two years ago, miners felt the pinch immediately. Revenue per hash dropped, and only those with cheap power or efficient rigs kept running. The rest had to find new revenue streams or shut down. AI compute, with its insatiable appetite for energy and specialized cooling, offered a natural outlet.
Power Capacity as the New Premium
Bitcoin miners control gigawatts of power capacity and interconnection rights. That's become a huge asset as AI companies hunt for large, reliable sites. In dense AI markets, an existing energized substation and a path to higher rack density can mean a major edge. Stock valuations now reflect this: power purchase agreements and interconnection value matter more than raw hashrate.
Conversion Hurdles
Turning a mining site into AI-ready infrastructure isn't cheap. Upgrades include liquid cooling, higher-spec electrical distribution — switchgear, UPS, generators — and high-throughput network fabric. Not every site can make the leap. Location matters: grid interconnection capacity, water availability, fiber routes, and community permitting all factor in. So does the existing substation's capacity.
Valuation Shift Underway
The market has noticed. Miners with strong power assets and conversion potential are seeing their shares re-rated. Those stuck on marginal sites face a tougher road. The next year should show which miners can actually deliver AI hosting at scale — and which can't.
