Stock Market Today July 4: TeraWulf Stock Jumps on Anthropic AI Deal

Stock market today, July 4: broad indexes pushed higher again while a Bitcoin miner turned AI landlord stole the spotlight. TeraWulf (NASDAQ:WULF) closed at $22.21, up 4.86%, after unveiling a lease deal with AI research firm Anthropic and a data center sale that together reshape how the company makes money.

Meanwhile bitcoin itself kept climbing. BTC/USD (CRYPTO:BTCUSD) traded at $63,990, up 0.64% on the day, a steady gain that underscores how mining stocks and the underlying coin are moving in tandem even as their business models diverge.

A $19 billion lease changes the calculus

The headline number here is $19 billion. That is the contracted revenue TeraWulf expects over a 20 year lease covering a new HPC site in Hawesville, Kentucky, with Anthropic as the tenant. Twenty years is a long runway for a company that started out mining bitcoin, a business defined by thin margins and constant hardware churn. Locking in two decades of predictable, contracted income is a very different animal, and it explains why traders piled in. Volume hit 73.3 million shares, roughly 135% above the three month average of 31.2 million shares.

TeraWulf also agreed to sell its 50.1% stake in a Texas data center joint venture, turning an original $450 million investment into about $530 million. That cash, paired with recurring lease payments, gives the company fresh flexibility to fund expansion without leaning as hard on bitcoin mining economics, which swing with coin prices and network difficulty.

Bitcoin's steady climb versus the mining stock rally

While WULF shares jumped nearly 5%, bitcoin's own move was more modest at 0.64%. That gap matters. Mining and infrastructure stocks often amplify bitcoin's price action because they carry operating leverage, fixed costs, debt, and now increasingly, big AI infrastructure bets. Peers told a similar story. Cipher Digital (NASDAQ:CIFR) rose 8.43% to $21.73, and IREN (NASDAQ:IREN) jumped 13.11% to $43.91, as investors kept betting on AI data center monetization across the whole group.

The broader market backdrop helped too. The S&P 500 (SNPINDEX:^GSPC) gained 0.74% to close at 7,538, and the Nasdaq Composite (NASDAQINDEX:^IXIC) rose 1.12% to 26,121, giving risk assets across the board a tailwind.

Why the miner to landlord shift carries risk

TeraWulf's transformation from a pure bitcoin miner into a recurring revenue HPC landlord looks appealing on paper, especially after May's land acquisition in Eastern Kentucky. But long term leases concentrate risk in a single tenant, and $19 billion in contracted revenue only materializes if Anthropic's business keeps growing over two decades. Bitcoin itself remains volatile by nature, and mining stocks tend to swing even harder in both directions. Anyone watching this space should treat today's gains as a snapshot, not a guarantee of where either bitcoin or its miners head next.
