Bitcoin miners valued as AI infrastructure play as AI-focused stocks surge 21% year-to-date

Something unusual is happening in the Bitcoin mining sector: the companies pulling back from mining are being rewarded for it. Miners that have pivoted toward artificial intelligence and high-performance computing infrastructure are outpacing their purely Bitcoin-focused peers by a wide margin, with a cohort of AI-integrated miners up roughly 21% year-to-date while the broader Bitcoin market trends lower.

The numbers tell the story

Core Scientific offers the clearest illustration of how fast this transition is moving. In Q2 2026, the company reported $136.7 million in colocation revenue, the kind that comes from hosting AI workloads, against just $27.5 million from Bitcoin mining. That is not a company with an AI side hustle. That is a company that mines Bitcoin on the side.

TeraWulf is posting approximately 73-74% gains year-to-date. RIOT has climbed roughly 94% over the same period. Meanwhile, the realized hashrate across public miners fell about 13.4% from Q4 2025 to Q2 2026, as companies redirected power capacity away from mining rigs and toward GPU-dense AI clusters.

The valuation gap between the two groups is equally telling. Miners with meaningful AI exposure are trading at over 12 times expected forward sales. Traditional Bitcoin miners, the ones still fully committed to solving blocks, are valued at somewhere between 2 and 6 times forward sales.

The economics back that up. AI cloud services are generating an estimated median of $940 per megawatt-hour. Bitcoin mining, by contrast, is producing somewhere between $113 and $179 per megawatt-hour.

A $70 billion bet on a sector pivot

The scale of the commitments being made here is not trivial. Cumulative AI and HPC contracts announced across the public mining sector now total somewhere between $70 billion and $100 billion. The catch is that actual billing is currently limited to around 550 megawatts of deployed capacity out of roughly 4 gigawatts under contract.

That gap also explains why this story is complicated for investors. The sector is staring at an estimated $50 billion funding requirement to bridge that gap, which is a significant overhang for companies that are, at their core, still running on mining cash flows while they build out AI capacity.

Some companies have responded by exiting Bitcoin mining entirely. Others are operating hybrid models, keeping their mining operations alive while carving out portions of their power capacity for AI tenants.

What investors are actually buying

Investors buying AI-exposed miners are not making a Bitcoin bet. They are buying access to power infrastructure and real estate at a time when both are genuinely scarce for large-scale AI deployments. That scarcity premium is visible in the valuation multiples. Twelve times forward sales is a number you typically see in high-growth software, not in companies that were recently classified as commodity producers.

The risk is that the timeline between signed contracts and realized revenue is long, capital-intensive, and subject to delays. A $50 billion funding gap across the sector means dilution, debt, or both for companies racing to build out their AI capacity. RIOT’s 94% gain year-to-date is impressive until you consider that it needs to execute flawlessly on a capital program measured in the billions to justify that valuation at maturity.
