Stock market today July 4: TeraWulf jumps 4.86% on a $19B Anthropic lease deal, while Cipher Digital and IREN rally on AI data center demand.
The stock market today (July 4) closed with fresh gains for a group of Bitcoin miners turned AI infrastructure plays, and TeraWulf led the pack after landing a massive lease deal with Anthropic. Shares of the Nasdaq listed company closed at $22.21, up 4.86%, on volume of 73.3 million shares, roughly 135% above its three month average of 31.2 million shares.
What Pushed TeraWulf Higher on July 4
TeraWulf announced a 20 year lease agreement for a high performance computing site in Hawesville, Kentucky, with AI research firm Anthropic. The deal is expected to generate about $19 billion in contracted revenue over its life, a figure that reframes how investors view a company once known mainly for churning out Bitcoin. Separately, TeraWulf agreed to sell its 50.1% stake in a Texas data center joint venture, expecting roughly $530 million for an original $450 million investment.
Together, the lease income and the sale proceeds give TeraWulf fresh capital and a more predictable revenue stream, a shift the market rewarded immediately.
From Mining Rigs to Data Centers
TeraWulf's pivot has been building for months. In late May, the company bought a large data center development site in Eastern Kentucky, laying groundwork for exactly this kind of AI infrastructure expansion. The Anthropic lease and the Texas sale mark the clearest sign yet that the company's bet on recurring, contracted revenue from AI computing demand is starting to pay off, rather than relying solely on the volatile economics of Bitcoin mining.
How the Broader Market and Peers Performed
The S&P 500 gained 0.74% to close at 7,538, while the Nasdaq Composite rose 1.12% to 26,121. Bitcoin mining and AI/HPC infrastructure names moved even more sharply. Cipher Digital climbed 8.43% to $21.73, and IREN jumped 13.11% to $43.91, as investors kept betting on how quickly these miners can monetize their data center assets for AI workloads rather than crypto alone.
| Company | Closing Price | Daily Change |
|---|---|---|
| TeraWulf (WULF) | $22.21 | +4.86% |
| Cipher Digital (CIFR) | $21.73 | +8.43% |
| IREN | $43.91 | +13.11% |
What Investors Should Weigh Going Forward
Bitcoin mining stocks remain tied to crypto prices, energy costs and regulatory shifts, and that volatility hasn't disappeared just because a company adds AI contracts to its book. TeraWulf's revenue mix is changing, but execution risk on a 20 year lease and the sale of a major joint venture stake still carries uncertainty. The stock's volume spike, well above its recent average, also signals a market reacting fast to news rather than settling into a steady trend.
Can TeraWulf Sustain Its AI Infrastructure Momentum
The Anthropic deal and the Texas sale give TeraWulf a stronger cash position and a long runway of contracted income, but whether that translates into consistent profitability over two decades remains an open question. For now, the market has responded with enthusiasm, pushing shares and several peers higher in a session where AI data center monetization was the clear theme across the sector.
