The blockchain and digital asset sector continues to evolve rapidly, with publicly traded companies driving innovation across Bitcoin mining, AI infrastructure, decentralized finance (DeFi), and green energy-powered data centers. As we move through 2025, several key players are emerging as leaders in scalability, operational efficiency, and strategic diversification. This article explores the latest developments from top blockchain stocks—IREN, Riot Platforms, CleanSpark, Hut 8, DeFi Technologies, and others—highlighting milestones in hashrate expansion, staking transitions, product launches, and corporate growth.
IREN: Scaling AI and Bitcoin Infrastructure
IREN Limited (NASDAQ: IREN) has made significant strides in both artificial intelligence and Bitcoin mining operations. In early July 2025, the company announced the acquisition of 2,400 NVIDIA Blackwell B200 and B300 GPUs, adding approximately $130 million in advanced computing capacity. This investment brings IREN’s total GPU fleet to 4,300 units, positioning it as a major player in next-generation AI cloud services focused on large-scale training and inference.

Simultaneously, IREN achieved a critical milestone in its Bitcoin mining division by reaching 50 exahashes per second (EH/s) of installed self-mining capacity by mid-year. Co-CEO Daniel Roberts described the achievement as a “defining milestone,” emphasizing the company’s ability to execute complex deployments at speed and scale.
These dual advancements underscore IREN’s hybrid strategy—leveraging high-performance computing for both AI workloads and cryptocurrency mining—making it one of the most diversified tech-forward blockchain stocks today.
Riot Platforms: Strengthening Market Position
Riot Platforms (NASDAQ: RIOT) remains a dominant force in the Bitcoin mining space. In June 2025, the company reported mining 450 BTC, reinforcing its status as a top-tier producer. More notably, Riot disclosed a 12.3% beneficial ownership stake in Bitfarms Ltd., signaling a strategic move to consolidate influence within the North American mining ecosystem.
This investment aligns with Riot’s broader vision of strengthening industry resilience through collaboration and equity participation. With access to low-cost energy and state-of-the-art facilities in Texas, Riot continues to optimize efficiency while expanding its digital asset treasury.
CleanSpark Achieves 50 EH/s with Full Operational Control
CleanSpark (NASDAQ: CLSK) has become the first publicly traded Bitcoin miner to reach 50 EH/s using fully self-operated infrastructure. The Las Vegas-based firm attributes its success to vertical integration, proprietary software optimization, and strategic site selection for power efficiency.
The company refers to this phase of rapid scaling as “Escape Velocity,” reflecting its transition from growth startup to industrial-scale operator. CleanSpark’s achievement highlights the importance of operational autonomy in an industry where uptime and energy costs directly impact profitability.
Hut 8 Powers Up Vega Data Center
Hut 8 Corp. (NASDAQ: HUT) energized its 205 MW Vega Data Center in late June 2025—an engineering feat believed to support up to 15 EH/s of next-generation ASIC mining capacity. Utilizing direct-to-chip liquid cooling, the facility sets new standards for thermal efficiency and environmental sustainability.
As one of the largest single-building Bitcoin mining sites by nameplate hashrate, Vega exemplifies Hut 8’s commitment to merging clean energy with high-density computing. The company continues to explore synergies between its mining operations and emerging AI workloads, further diversifying revenue streams.
DMG Blockchain Reports Operational Adjustments
DMG Blockchain Solutions (OTCQB: DMGGF) released preliminary results for June 2025, reporting 23 BTC mined and a network hashrate of 1.56 EH/s, down slightly from May’s 1.89 EH/s. While the reduction may reflect maintenance cycles or market-driven adjustments in hash allocation, DMG maintains a strong operational foundation with vertically integrated data center capabilities.
The Canadian firm continues to focus on secure, transparent mining operations and is exploring opportunities in decentralized identity and green tech integration.
Cipher Mining Begins Operations at Black Pearl
Cipher Mining (NASDAQ: CIFR) successfully commenced Bitcoin mining at its 300 MW Black Pearl data center in Texas. Phase I is now live at 150 MW, contributing to a current total hashrate of ~16 EH/s, with expectations to grow to 23.1 EH/s by Q3 2025.
This milestone marks Cipher’s full entry into industrial-scale mining operations, supported by long-term power agreements and modular infrastructure design that allows for rapid deployment and scalability.
Soluna Expands Sustainable Mining Partnerships
Soluna Holdings (NASDAQ: SLNH) strengthened its position in eco-friendly computing through two key partnerships in June 2025:
- Renewed and expanded collaboration with Compass Mining, increasing capacity at Project Dorothy 2 to 13 MW.
- Signed an expanded hosting agreement with Blockware Solutions, boosting sustainable hosting capacity by over 50% to 8 MW.
These moves reinforce Soluna’s mission to build green data centers powered by renewable energy, aligning environmental responsibility with profitable blockchain operations.
