Key points
- AI infrastructure stocks are surging together Wednesday, led by TeraWulf (WULF) up about 10%, Nebius (NBIS) up roughly 5%, and IREN up about 4%, with the rest of the group higher too.
- Two names are red instead of green: HIVE Digital (HIVE) and CleanSpark (CLSK), the two companies in this group that still earn most of their revenue from bitcoin mining rather than AI infrastructure.
- WULF and IREN ran hardest Monday on TeraWulf's $19 billion Anthropic lease and unconfirmed Australia data center speculation, gave it back Tuesday, dipped further overnight, then reversed hard at Wednesday's open.
- None of today's move traces back to fresh, company-specific news. The split between who is up and who is not lines up almost perfectly with how much of each company's business is actually AI infrastructure versus bitcoin mining.
The AI infrastructure trade is back in favor Wednesday, and it is not just one or two stocks. TeraWulf (WULF) is leading the group higher, up about 10%, with pure-play neocloud Nebius (NBIS) close behind at roughly 5% and IREN up about 4%. CoreWeave (CRWV) and the rest of the group are participating too, just with smaller moves. Two names are sitting this one out entirely, and they are not random.
The board
| Stock | Move |
|---|---|
| TeraWulf (WULF) | +10.1% |
| Nebius (NBIS) | +5.0% |
| IREN | +3.7% |
| CoreWeave (CRWV) | +2.7% |
| Cipher (CIFR) | +1.9% |
| Core Scientific (CORZ) | +1.2% |
| Hut 8 (HUT) | +0.9% |
| Applied Digital (APLD) | +0.2% |
| Keel Infrastructure (KEEL) | -0.1% |
| HIVE Digital (HIVE) | -0.3% |
| CleanSpark (CLSK) | -2.0% |
Eight names are green together, which is the signature of a sector move rather than eight individual stories. HIVE and CleanSpark are red, and they are also the two names in this group with the least actual AI business to point to. CleanSpark still earns nearly all of its revenue from bitcoin mining, and HIVE's AI compute arm remains the smaller, earlier-stage piece of its business next to its mining operation. Meanwhile, Nebius and CoreWeave, both pure-play neoclouds that were never bitcoin miners at all, are up right alongside the group. If this were purely a bitcoin-price move, the miners would be moving together and the neoclouds would not be involved. That is not what happened. This is an AI-infrastructure bounce specifically, not a blanket crypto-adjacent one.
The same two names that ran Monday, then gave it back
WULF and IREN are not new to this week. TeraWulf signed a 20-year, roughly $19 billion lease with Anthropic on Monday, and the stock spiked as high as 18% that day before fading back to a 5% close, a classic sell-the-news pattern. IREN ran on the same day, tied to unconfirmed speculation about a separate Anthropic data center project in Australia. Neither stock held those gains into Tuesday. WULF closed Tuesday at $20.24, down from Monday's highs, and IREN slid to $39.82.
Both stocks fell further overnight into Wednesday, IREN touching a premarket low near $38 and WULF dipping under $19.50, before reversing hard once regular trading opened.
Why the whole group moved, not just two stocks
None of this week's price action across these eleven names points to fresh, company-specific news, for the ones that are up or the two, HIVE and CleanSpark, that are clearly not. The whole group got pulled into Tuesday's broader memory and chip-sector selloff, the same pressure that hit Samsung and Micron, and softened further overnight alongside a broader pullback in risk assets tied to overnight macro jitters. Wednesday's bounce looks like the mirror image for the AI-linked names: money that left on no company-specific news came back the same way. HIVE and CleanSpark fell with everyone else Tuesday, they just have not gotten the same bounce back.
That pattern, a real earnings or deal catalyst driving one or two names higher, followed by the whole neocloud and AI-infrastructure group trading together on broader sentiment, has shown up repeatedly this cycle. It is worth remembering when one of these stocks moves 10% or more in a single session: check whether the rest of the group moved too before assuming it is about that company specifically.
What to watch
Whether WULF, NBIS, and IREN can hold anywhere near today's highs into the close matters more than the intraday number. All three stocks have shown this week that a sharp pop on no lasting news tends to fade. The more durable story for TeraWulf is still the Anthropic lease itself, a real 20-year contract, not today's bounce. For IREN, the open question is whether it ends up with any actual role in Anthropic's still-unconfirmed Australia buildout. For HIVE and CleanSpark, the question is different: whether either can point to an AI infrastructure story of its own that is big enough to pull it into the next group move, instead of sitting out again.
