Crypto Miners Turn to AI and Data Center Infrastructure for New Growth

Bitcoin mining margins have tightened since the network’s April 2024 halving cut the block reward to 3.125 BTC, leaving operators more exposed to bitcoin prices, network difficulty and power costs. Public miners have responded by repurposing grid connections, land and data-center capacity for artificial intelligence and high-performance computing, where multiyear hosting contracts can provide steadier cash flow. The shift is recasting listed miners as digital-infrastructure companies rather than pure proxies for bitcoin production.

BlocksBridge Consulting said in an analysis published Aug. 13, 2026, that aggregate hashrate among publicly traded bitcoin miners fell 13.4% over six months as capacity moved toward AI and HPC. TeraWulf’s second-quarter HPC leasing revenue rose 52% from the prior quarter to $31.9 million, accounting for 71% of total revenue, while bitcoin-mining revenue dropped 73% year on year to $12.8 million. Core Scientific also generated most of its revenue from non-mining operations, underscoring the sector’s accelerating pivot.

Bitcoin miners are increasingly repurposing power-rich sites and data-center expertise for artificial intelligence and high-performance computing as mining economics weaken. Operators such as Hut 8 and IREN can bring capacity online faster than many greenfield developers because they already control grid connections, land and infrastructure. Long-term AI leases and cloud contracts also promise steadier revenue than cryptocurrency mining, making the transition a central driver of investor valuations across the sector.

On July 20, Hut 8 announced a second 15-year, $9.8 billion lease at its Beacon Point campus in Texas, taking the site's combined base-term contract value to $19.6 billion. IREN disclosed $2.8 billion of new multi-year cloud contracts and raised its year-end 2026 AI Cloud annualized revenue target to more than $4 billion, with about 85% under contract. Hut 8 and IREN shares rose more than 16% and 17%, respectively, while several mining peers gained at least 11% in early trading.

AI training and inference are driving a surge in data-center electricity demand, but building new substations and securing grid connections often takes years. Bitcoin miners already control large-scale power contracts, land, substations and fiber connectivity, allowing them to take on AI and high-performance computing workloads faster than projects built from scratch. Success still depends on cooling systems, building retrofits and long-term customers.

A June 30 report said mining sites' grid connections had evolved from a cost of Bitcoin production into an AI asset. On February 26, 2025, Core Scientific expanded its CoreWeave contract to 590 MW, with estimated revenue of $10.2 billion over 12 years. On January 16, 2026, Riot Platforms signed a 10-year, $311 million lease with AMD, beginning with 25 MW and offering expansion to as much as 200 MW.

Institutional expansion is moving crypto assets beyond a trading theme and into corporate treasuries and computing infrastructure. Twenty One Capital, backed by Tether, Bitfinex, Cantor Fitzgerald and SoftBank, holds more than 42,000 Bitcoin. Bernstein said miners can repurpose existing power supplies and data centers for AI, adding a source of revenue following the halving.

On May 19, 2026, Tether acquired SoftBank’s approximately 26% stake in Twenty One Capital for an undisclosed amount. The same day, Polymarket and Nasdaq Private Market launched a prediction market for private companies. A May 18 report from CoinShares showed that digital asset funds recorded $1.07 billion in net outflows in the previous week, ending a six-week streak of inflows.

Bitcoin miners traditionally used energy-intensive computing to maintain the blockchain, but their grid connections, land, cooling systems and data centers can be converted relatively quickly into high-performance computing facilities for AI. Bitcoin completed its fourth halving on April 20, 2024, cutting the block reward to 3.125 BTC. The resulting pressure on mining revenue has also prompted operators to seek more stable income from AI hosting.

In a May 19, 2026, report, Bernstein estimated that publicly traded Bitcoin miners control more than 27 GW of planned power capacity. The industry has announced more than $90 billion in AI agreements covering about 3.7 GW. Bernstein also assigned outperform ratings to IREN, Riot Platforms, CleanSpark and Core Scientific, underscoring how access to power has become a bottleneck for AI data-center expansion.

Bitcoin undergoes a halving roughly every four years. In April 2024, the block reward fell from 6.25 bitcoin to 3.125 bitcoin, while CoinGecko estimated the cryptocurrency’s price at about $63,000 at the time. The reward is expected to fall again to 1.5625 bitcoin in April 2028. With energy costs and competition for computing power rising, miners need revenue from AI, high-performance computing and diversified power sources to reduce their reliance on mining alone.

From March 4 to March 25, 2026, MARA Holdings sold 15,133 bitcoin worth about $1.1 billion to repurchase $1 billion of convertible debt, a move expected to reduce its debt by about 30%. Bitdeer’s bitcoin holdings had fallen to zero as of February 20. Cango, meanwhile, plans facilities that can switch between AI and mining, while miners that have secured HPC contracts now command revenue multiples more than twice those of pure-play miners.

After Bitcoin's April 2024 halving, mining rewards shrank while network hashrate and electricity costs climbed. CoinShares estimates that listed miners' average cash cost per BTC reached $79,995 in the fourth quarter of 2025, above Bitcoin's roughly $68,000–$70,000 price in March 2026. Miners can repurpose their existing power capacity and data centers for AI computing, making the shift consequential for both corporate finances and Bitcoin network security.

As of March 2026, listed miners' combined BTC holdings had fallen by more than 15,000 coins from their peak. Core Scientific sold about 1,900 BTC worth $175 million in January, while Bitfarms cut its holdings from a peak of 3,301 BTC to 1,827 BTC. The industry has signed more than $70 billion in AI and high-performance computing contracts, including Core Scientific's 12-year, $10.2 billion agreement with CoreWeave.
