JPMorgan Backs IREN’s AI Shift, Cuts MARA’s Capital‑Light Play

When the big banks start gossiping about crypto miners, the rest of us sit up and listen. This week JPMorgan pulled out two very different verdicts – a glowing upgrade for IREN Ltd. (IREN) and a double‑down downgrade for MARA Holdings Inc. (MARA). The reason? How each company is turning the electricity that powers Bitcoin mining into something more lucrative, like AI compute.

JPMorgan’s research note paints IREN as a “top‑tier” neocloud provider, and it’s not being modest about the upside. The bank pegs the stock’s potential at roughly a 48 % rise from its Friday close, nudging the price target up to $65 from $46. Why the optimism? IREN has built a fully vertical stack – it owns the land, the power connections, the data‑center bricks, buys the GPUs, and sells the compute directly to customers. In other words, it’s not just renting a floor of a data centre; it runs the whole building, the elevator, and the rooftop garden.

That vertical integration also lets IREN repurpose the very same power capacity that once churned out Bitcoin into AI workloads. The firm has already signed a handful of customers, and with industry pricing on the rise, JPMorgan believes the momentum will only accelerate through 2027. The bank did note, however, that IREN still mines Bitcoin today and plans to wind that operation down by the end of 2026 – a move meant to free up even more electricity for AI.

Contrast that with MARA, which has taken a “capital‑light” route. Instead of building its own facilities, MARA keeps the land, hands over the construction and operation of data centres to partners, and hopes to reap the upside from the joint‑venture structure. JPMorgan isn’t buying the story. It cut MARA’s rating from overweight to underweight, and trimmed the price target from $13 to $11, arguing that other miners are extracting more direct value from their power assets.

In plain English, the bank thinks MARA’s approach dilutes value creation. While competitors are funneling existing electricity straight into high‑margin AI compute, MARA is, in JPMorgan’s view, spreading the pie too thin by sharing control with partners. The market reacted predictably – MARA’s shares slipped more than 6 % in pre‑market trading, settling at the very target JPMorgan set.

Retail sentiment on Stocktwists mirrors the analysts’ split view. IREN’s chatter sits in a bearish zone, but that’s likely because the stock dipped a touch in early trading amid broader market softness. Meanwhile, MARA’s sentiment stayed neutral, with low levels of discussion overall.

All told, the takeaway is clear: investors are starting to value Bitcoin miners not just for the coins they crank out, but for how cleverly they can redeploy that massive power draw. IREN’s all‑in‑house model looks like a winner to JPMorgan, while MARA’s partner‑centric, capital‑light strategy is seen as a step backward. Whether the market will follow the bank’s lead remains to be seen, but the conversation around “power‑to‑AI” is definitely heating up.
