$NBIS vs $IREN Revisited: Which One Is More Undervalued?

Let's put these two neocloud names side by side again. Their business models are quite different, and it turns out the market is pricing them at noticeably different valuations too.

1. Current Price and Market Cap Check

$NBIS is trading at $182.62 (+2.76% from the prior close), with a market cap of $46.76B (per https://t.co/h0RpFlZHVY). Its 52-week range runs from $49.00 to $299.86.

$IREN is trading at $40.20, with a market cap of $14.37B. That's up +19.6% from yesterday's close of $33.62 — the stock has kept climbing today on top of yesterday's ARR guidance raise. Its 52-week range is $14.72 to $76.87.

The market cap gap between the two is roughly 3.3x.

2. Business Model Differences

< $NBIS >
A Dutch entity that grew out of Yandex's former European business. It runs a full-stack model — GPU clusters, a cloud platform, and developer tools — to deliver AI infrastructure end to end. It recently (7/15) unveiled a new "infrastructure partnership" model, where partners fund and own the infrastructure/hardware while $NBIS supplies the systems architecture, software stack, and global sales — effectively shifting toward an asset-light approach.

< $IREN >
Originally a Bitcoin mining company, $IREN runs a vertically integrated model that covers everything from securing power to operating the GPUs itself. It sells compute directly to customers through Bare Metal and Managed Cloud offerings.

So $NBIS is moving toward "lighter," while $IREN is still carrying the whole stack itself — an interesting contrast, I think.

3. Where Things Stand Right Now

< $NBIS >
It has locked in a cumulative $46B+ in multi-year contracts with Meta and Microsoft. Q1 2026 revenue came in at $399M (+684% YoY), with AI cloud making up 98% of that. Core AI Cloud ARR reached $1.92B by end of Q1 (+54% QoQ), and it raised its year-end 2026 contracted-power target to 4GW. A recent $775M debt raise has eased dilution concerns somewhat, but when the asset-light model was announced, the lack of detail on partner names and revenue-sharing terms seems to have been read by the market as added uncertainty.

< $IREN >
Yesterday it signed $2.8B in new multi-year contract TCV, raising its 2026 ARR target from $3.7B to $4.0B+, with coverage now at 85%. The new contracts also include customer prepayment of about 45% of GPU capex. That said, last month's controversy over the CEO's $800M RSU package did put governance risk in the spotlight.

4. What the Market Thinks (Analyst Consensus)

< $NBIS >
The average price target sits around $238 (range $110–$380). Citi is at $287, Goldman at $205 (Buy), and Northland at $410 (Outperform). Consensus across 10–17 institutions leans "Buy/Overweight."

< $IREN >
Per https://t.co/h0RpFlZHVY, the price target is $80.93, implying about +101.33% upside. The analyst rating is Buy, while the technical rating is actually Strong Sell — a fairly sharp split between the fundamental view and the near-term technical picture, I'd say.
5. Comparing Upside

$NBIS: current price $182.62 → average target $238 implies roughly +30% upside.
$IREN: current price $40.20 → target $80.93 implies roughly +101% upside.

On paper $IREN's upside looks more than double, but a lot of that gap comes from how hard it sold off over the past month — so it's probably better read as a reference point than a clean apples-to-apples signal.
6. Valuation — Comparing ARR Multiples

$NBIS: $46.76B market cap ÷ 2026 ARR target of $7–9B (midpoint $8B) ≈ 5.85x

$IREN: $14.37B market cap ÷ 2026 ARR target of $4.0B+ ≈ 3.59x

Even after today's rally, on an "AI infrastructure ARR" basis $NBIS is still trading at more than 60% higher a multiple than $IREN.

7. Conclusion — Which One's Actually Undervalued?

Going purely by ARR multiple and analyst upside, $IREN does look relatively cheaper.

That said, I wouldn't take that at face value as "$IREN is cheap, case closed." $NBIS brings far more certainty — its revenue growth (+684% YoY) and its anchor customers in Meta and Microsoft are hard to argue with — while $IREN's discount partly reflects last month's governance controversy.

Bottom line: $NBIS seems to be trading at a premium for certainty, while $IREN is trading at a discount for noise. Whether that discount stays noise or turns into something more real is probably the thing to watch going forward.
