Bitcoin Miners Are Becoming AI Stocks: Best Crypto Mining Stocks for 2026

• Crypto mining stocks are pivoting to AI. MARA, RIOT, CLSK, IREN, and WULF are no longer just Bitcoin plays.
• Starboard Value says Riot’s Texas power assets could generate over $1.6B in annual EBITDA from AI hosting.
• IREN up 494% with a $9.7B Microsoft deal. CleanSpark at 57% discount to fair value. TeraWulf has a Morgan Stanley target double its current price.

Crypto mining stocks are no longer a simple bet on Bitcoin’s price. The five biggest publicly traded Bitcoin miners, MARA Holdings, Riot Platforms, CleanSpark, IREN, and TeraWulf, are converting their power infrastructure into AI data centers, signing contracts with hyperscalers, and repositioning themselves as digital infrastructure companies. For investors looking at the best Bitcoin mining stocks in 2026, or trying to figure out which mining stocks to buy now, the story has fundamentally changed: power access, not hashrate, is now the asset that matters.

From Bitcoin to AI: Why Mining Stocks Are the Picks and Shovels of 2026

The shift accelerated after Bitcoin’s April 2024 halving cut block rewards in half. With rising power costs and compressed margins, miners with large power portfolios realized their most valuable asset was not their ASICs but their access to cheap, large-scale electricity. That access is now being monetized through AI and high-performance computing deals with some of the biggest names in tech.

1. MARA Holdings (MARA)

MARA currently holds 53,822 BTC and runs a hashrate of 66.4 EH/s, making it the largest Nasdaq-listed Bitcoin miner by BTC held. A partnership was announced with Starwood Capital Group to develop AI data centers across existing U.S. sites, targeting around 1 gigawatt of capacity near term and over 2.5 GW longer term. MARA shares jumped 17% on the news. Starwood, which manages more than $125 billion in assets, will handle design, construction, and tenant sourcing through its Starwood Digital Ventures arm.

MARA CEO Fred Thiel has been clear that mining is not being abandoned. “Bitcoin remains a core pillar of MARA’s strategy,” Thiel wrote in a shareholder letter. “While the timing of a recovery in bitcoin prices is difficult to predict, our long-term conviction in the asset class remains unchanged.”

The treasury shift is also worth watching. In its 2025 Form 10-K, the company stated it had expanded its strategy “to allow for sales of bitcoin held on our balance sheet,” adding that it “may hold bitcoin for long-term investment purposes and may also buy or sell bitcoin from time to time, subject to market conditions and our capital allocation priorities.” MARA also recorded a $422.2 million decline in the fair value of its holdings over 2025.

2. Riot Platforms (RIOT)

Riot posted record annual revenue of $647.4 million for 2025 and holds 18,005 BTC, with $1.9 billion in total liquidity. An AMD data center lease at its Rockdale, Texas site started generating revenue in January 2026. CEO Jason Les called 2025 a “watershed year” and said the company has “never been in a stronger position.”

Activist investor Starboard Value published a letter in February 2026 urging Riot to accelerate its AI infrastructure transition. Starboard argued that Riot’s 1.7 gigawatts of available power at its Corsicana and Rockdale Texas sites could “generate more than $1.6 billion” in annual EBITDA if monetized through premium AI hosting deals. The letter urged CEO Jason Les and Executive Chairman Benjamin Yi to act “with urgency.”

3. CleanSpark (CLSK)

CleanSpark reached a peak hashrate of 50 EH/s and holds 13,363 BTC at the time of writing. In February 2026, the company closed on a second Texas campus, adding 300 MW of ERCOT-approved capacity to its portfolio, bringing contracted power to more than 1.8 GW across the U.S.

CEO Matt Schultz described the February expansion as a step toward building “hyperscale-ready infrastructure” and said CleanSpark is also “advancing AI and high-performance compute initiatives while maintaining focus on world-class operational excellence in bitcoin mining.”

Analysts have placed a fair value of around $23.16 on CLSK against a current price near $9.95, one of the steeper discounts among crypto stocks to buy in 2026. The company mined 568 BTC in February and sold 553 BTC at an average price of $66,279, generating roughly $36.6 million in proceeds.

4. IREN Ltd (IREN)

IREN is the largest publicly traded miner by market cap and also the most aggressive in its AI pivot. The company holds no Bitcoin. It secured a $9.7 billion, 200 MW infrastructure agreement with Microsoft and has ordered more than 50,000 Nvidia B300 GPUs, bringing its total planned fleet to 150,000 units. Management is targeting a $3.7 billion AI Cloud annualized run rate by end of 2026.

The Microsoft deal comes with substantial funding commitments and no immediate dilution for existing shareholders, though execution risk remains real given the scale of GPU deployment and capital intensity involved.

5. TeraWulf (WULF)

TeraWulf has secured more than $12.8 billion in long-term contracted revenue and $6.5 billion in financing commitments. On March 13, 2026, the company closed a $500 million delayed-draw bridge credit agreement with Morgan Stanley to fund a new AI data center in Hawesville, Kentucky, a former industrial site with 480 MW of current power capacity and room to scale.

The Hawesville build is anchored by a Google-backed lease and equity stake. Morgan Stanley started coverage in February with an Overweight rating and a price target of $37, against a current price near $16. Cantor Fitzgerald, Keefe Bruyette and Woods, and Rosenblatt Securities all carry Buy or Outperform ratings. Across 14 analysts, the consensus sits at Moderate Buy with an average target of $20.62. The stock has risen more than 350% over the past year.

The market is reframing these five companies as infrastructure plays with hard assets, contracted power, and growing AI revenue streams. The Bitcoin miner AI pivot is real and accelerating, and right now the market still prices most of them as crypto stocks.
