TeraWulf's stock surged in Monday trading after the crypto-mining company announced a $19 billion deal with AI firm Anthropic. The agreement shifts TeraWulf's focus from cryptocurrency mining to supporting the AI buildout — a move its CEO said 'validates' the pivot.

The deal comes as a broader chip stock rally lifted Wall Street, with indices surging amid renewed investor confidence in the semiconductor sector. Meanwhile, Samsung Electronics is moving to reassure chip investors, emphasizing its strategic investments in AI chips to counter jitters in the AI trade.

Markets responded broadly: TeraWulf shares led the surge, while chip stocks across the board gained. The rally extended to Asian markets, though oil prices remained flat. The $19 billion commitment from Anthropic underscores the growing capital flows into AI infrastructure, diverting investment from traditional crypto mining and tech sectors.

Forward guidance remains cautiously optimistic. Some analysts warn that such large-scale AI infrastructure deals carry execution risks, particularly given the volatile regulatory landscape surrounding both crypto and artificial intelligence. TeraWulf's pivot may face scrutiny from investors watching for sustained revenue beyond the initial deal.
