Data Center Stocks Rally With Bitcoin: Cipher Mining Jumps 12%, TeraWulf Surges 8%, IREN Rises 4%

Bitcoin miners turned data center operators are surging today, but the rally reveals a strange disconnect: these stocks still chase the coin even as billion-dollar AI lease deals rewrite what these companies actually are.

Bitcoin-linked data center operators are rebounding today as Bitcoin (CRYPTO:BTC) stabilizes near recent lows, and none of the intraday moves trace to a fresh company announcement. The group carries its old mining identity into every session even as the underlying businesses evolve toward AI infrastructure. That gap between what these companies now sell and what their share prices respond to defines the trade.

The framing sits in the benchmarks. The Global X Data Center & Digital Infrastructure ETF (NASDAQ:DTCR) is up 2% to $27.87, while the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is up 1% to $774.02. Both funds sit well behind the individual miner moves, which places today’s rally in the speculative corner of the data center theme rather than across the sector broadly.

Cipher Mining (NASDAQ:CIFR) stock is up 12% to $17.08, retracing part of a steep monthly drawdown. Meanwhile, TeraWulf (NASDAQ:WULF) stock is up 8% to $15.95, the middle mover in the group and the name that already gets most of its revenue from something other than mining. IREN (NASDAQ:IREN) stock is up 4% to $41.14, the smallest of the three moves and the least bruised name entering the session. As for Bitcoin itself, it trades at $81,204.22, up 5% over the past 24 hours.
