TeraWulf’s stock surges after a $19 billion deal with Anthropic

TeraWulf (WULF) shares rallied sharply after the company announced it is tied to a reported $19 billion deal with Anthropic, the AI safety startup backed by Amazon and Google. The company's CEO framed the deal as validation of WULF's strategic pivot away from Bitcoin mining toward providing power and data-center infrastructure for the AI buildout. No granular contract terms — revenue recognition timeline, capacity commitments, or pricing — have been disclosed publicly.

The headline matters because WULF has been repositioning its nuclear-powered mining sites as low-carbon AI compute infrastructure, a narrative that commands a significant valuation premium over pure-play crypto miners. FY2025 revenue of $151.6M grew only 8.2% YoY — modest for a company priced on a hyperscale AI story — and gross margins of 43.6% are reasonable, but net margins of -436% reveal deep losses, likely driven by depreciation, interest, and buildout capex.

The bull case hinges on whether the Anthropic relationship translates into contracted, recurring revenue at scale — a single large hyperscaler anchor tenant could fundamentally re-rate WULF's revenue trajectory and justify the infrastructure capex. The bear case is that the deal details are opaque, the stock has already surged on the headline, and the underlying financials show a company burning significant cash with no near-term path to net profitability.

Key things to watch: formal contract filings or 8-K disclosures with revenue figures, any Anthropic commentary confirming capacity commitments, and whether WULF's management provides updated guidance. The gap between the headline pop and the thin financial disclosure creates classic 'sell the news' conditions if details disappoint.
