tcoin Miners Jump as Microsoft Unveils $17.4B AI Investment

Bitcoin Miners Jump on Microsoft’s $17.4B AI GPU Deal Despite Bitcoin Weakness
September 10, 2025

Shares of bitcoin miners soared Tuesday as Nebius Group announced a five-year, $17.4 billion agreement to supply Microsoft (MSFT) with GPUs for its AI infrastructure. The deal fueled investor enthusiasm for companies with large-scale computing capacity, even as bitcoin (BTC) declined roughly 1% to $111,100 over the past 24 hours.

Leading the rally, Bitfarms (BITF) surged 22%, followed by Cipher Mining (CIFR) up 20%, while Hut 8 (HUT), Riot Platforms (RIOT), TeraWulf (WULF), and IREN posted mid-teens gains. MARA Holdings, which focuses more on bitcoin treasury management than high-performance computing, rose a modest 4%, highlighting the market’s preference for miners with scalable infrastructure.

The sector’s performance underscores a shift in the mining business model. Profitability is no longer solely tied to bitcoin’s halving cycles. Rising energy costs, expanding hardware production, and intensifying competition have altered the landscape. Miners with advanced infrastructure are increasingly leasing computing power to hyperscalers or offering data center services, leveraging their GPU capacity to tap into the AI boom.

The Nebius-Microsoft agreement highlights the growing value of high-performance GPUs and why the market is rewarding miners with the infrastructure to serve AI and other high-demand computing applications.
