Bitcoin Mining Sector Surges in Early Trading as Market Cap Nears $90 Billion

Bitcoin Miners Rally Pre-Market as AI Demand Spurs Optimism

Bitcoin (BTC, $118,137) miners are extending pre-market gains as rising demand for artificial intelligence (AI) and high-performance computing (HPC) drives investor interest. Miners focusing on AI infrastructure are leading the rally.

IREN (IREN) is up 4% pre-market at $66 after a 6% gain Thursday, bringing its year-to-date rise above 520%. TerraWulf (WULF) climbed 5% pre-market following a 10% surge Thursday, lifting its YTD gain to 150%. Cipher Mining (CIFR), CleanSpark (CLSK), and Bitfarms (BITF) are all trading 2–4% higher.

The Bitcoin mining sector’s market capitalization is approaching $90 billion, according to Farside data, and could exceed $100 billion by year-end if current momentum continues.

Broader industry trends support the rally. Bloomberg reports Microsoft (MSFT) will face data center shortages into 2026 due to surging cloud and AI demand. Even with added capacity of up to two gigawatts, scaling remains a challenge, boosting optimism for miners expanding into AI and data center operations.
