NVIDIA Spectrum X scale-out CPO Switch

This is the Ethernet version of the Quantum X CPO switch (which uses InfiniBand)

It has only one ASIC compared to Quantum X, which has 4.

It has 32 optical engines compared to Quantum X, which has 72.

But it has 16 ELS modules compared to Quantum X, which has 18.

overall the laser to optical engine ration goes from 4:1 to 2:1, meaning Ethernet switch adoption is relatively bullish for InP and bearish for SiPho.

The Ethernet version will likely ship in more volume.

In investing, a lot of information you can acquire via the internet and Claude tokenmaxxing.

But there is an entirely different world which you can only tap into through conferences and in-person conversations.

This post is the result of spending a full week in Taipei staring at racks and talking to people! We cover

1. Immersion Cooling
2. Fuel Cells
3. Hiwin (Robotics Supplier)
4. DRAM
5. Kyber Racks
6. Astera Labs
7. Nvidia RTX Spark (Laptops)
8. MediaTek MicroLED
9. Scale-Out CPO
10. Scale-Up CPO

And some implications for CPO players like $LITE.

Great overview of $RBRK by Sergey 👇

Something many have missed out on when looking at top-line deceleration this quarter is the impact of material rights.

Adjusting for that, the top-line deceleration moving forward is much more muted than a first look would suggest.

[Jason's Chips @jasonschips]

Look at how much copper is used in NVDA racks for scale-up. You can feel how much of the mass of the rack is just the cabling.

Now imagine how much worse it gets when we try to push higher bandwidths, necessitating even wider cables (due to the skin effect).

Do you see why we need CPO?

We are more confident than ever that we are in the early innings of the AI acceleration opportunity,” said Bipul Sinha, Rubrik’s Chief Executive Officer, Chairman, and Co-Founder.

Commenting on the company’s financial results, Kiran Choudary, Rubrik’s Chief Financial Officer, added, “We are pleased with our strong start to fiscal year 2027, exceeding all guided metrics with subscription ARR of $1.57 billion growing 32% year-over-year and free cash flow margin of 19%.

$RBRK CEO Bipul Sinha says cybersecurity strategy has moved from being prevention and detection oriented to being squarely a cyber resilience strategy. With Mythos, cyber detection is almost impossible and as soon as an intrusion happens, a breach will happen. Gartner sent a note to clients that the real answer to Mythos is cyber resilience. He has personally done 140 CIO and CISO meetings in the last quarter, up 50% sequentially. Cyber resilience is the only cybersecurity strategy that is viable for the AI era.

"What I'll say is cyber security strategy has moved from being a prevention/detection-oriented strategy to being squarely now a cyber resilience strategy. And what Mythos and other frontier AI models have done, they have accelerated this transformation because with Mythos, cyber detection is almost impossible. As soon as an intrusion happens, a breach will happen. And as Gartner also sent out, a note to all the clients that the real answer to Mythos is cyber resilience, a must, and preemptive technologies have to be explored both for patching as well as cyber recovery.

And if you look at Rubrik Inc, call it vision, call it luck, call it right time, right place. Two years ago, we launched something called Preemptive Recovery Engine, which does all the work of cyber recovery in the peacetime before an attack happens so that when an attack happens, you are ready to recover at AI speed. In this new era of AI, Mythos and AI-powered attacks, recovery at AI speed is critical and Rubrik Inc has a unique technology to deliver that for our customers.

In fact, our vision is attacks will be continuous and recovery has to be continuous. So at any given point in time, you have to be ready to recover at AI speed. And that's what our Preemptive Recovery Engine delivers. That's what we are educating our customers on.

And if you just look at what has happened post Mythos, I have personally done 140 CIO and CISO meetings in the last quarter. That is up 50% sequentially, quarter-over-quarter. Cyber resilience is the only cyber security strategy that is viable for the AI era. We created the cyber resilience category and we are taking our customers on this agentic cyber resilience journey."

There's another piece of alt data out today which shows $RDDT growing Q2 ad revenues at 59-60% YoY vs sell side at 47% YoY.

$RDDT ad revenues are usually 93-94% of total revenues... this implies $RDDT might be on track to report $790-800M in Q2 revs vs sell side estimates at $729M

If $RDDT beats consensus by 9-10% on the top line, they probably beat by way more on the bottom line because they have 90% gross margins.

if $RDDT does $790-800M in Q2 and net income margins come in at 42% (similar to Q1), then there's a path to $1.75 EPS or better (depending on stock buybacks)... vs sell side at $1.45 EPS (20% beat)

So, whatever their revenue % beat in Q2, it's very likely their eps % beat is 2x bigger.

I'm very confident this is a $300 stock in the next 6-12 months.

Hello $NU buyback.

$1B share repurchase program announced today.

Very little dilution happening right now so that should directly eat into share count.

And I’m sure the first of many programs for a company like this… rapidly growing and printing money.

Glad to see this. Priority one is spending on growth. But they have an elite balance sheet & can do both.

[ppdd @usppdd]

This is actually huge news, as it suggests @ousterlidar’s sales to Amazon could multiply.

Amazon’s 3.2M $OUST warrants become fully vested once cumulative revenue surpasses $100M, and roughly 2.8M warrants have already vested.

If the next-generation Proteus robots are deployed at scale and require multiple LiDARs per unit, the potential revenue opportunity from Amazon alone could reach hundreds of millions of dollars. $OUST

$RDDT CEO dropped a bomb on an AMA yesterday that the market might be waking up to.

Reddit’s data is invaluable for AI labs, the market hasn’t caught on yet.

“Foundational models benefit from Reddit in pre training, post training, grounding, and search because our authentic human perspective is increasingly rare.

That’s why people are increasingly looking to Reddit for real opinions and real experiences - and why Reddit content is the #1 cited source across LLMs.

No other data source can replicate the continuously-generated, community-curated, preference-labeled map of how humans actually communicate and make judgments.

These partnerships are meaningful to us and to our partners, and it’s important to us to have partnerships that capture the value only Reddit can bring.”

That sounds like big deals are coming.

S&P 500 inclusion (if not this quarter then next), data licensing deal renewals, and the Anthropic litigation settlement are on the horizon.

$NVDA Kyber rack has a beautiful and elegant design.

Compute blades (GPUs) slot in vertically from the front while NV switch modules go in horizontally from the back. They meet in the middle via an orthogonal copper backplane.

If the supply chain can support it (M9CCL shortage), this design can save a ton of floor space once Rubin Ultra ramps in 27/28

$NVTS showcased its 800V-to-6V DC-DC power delivery board at NVIDIA’s AI Factory MGX ecosystem event during Computex.

The board uses 16 GaNFast FETs and targets 97.5% peak efficiency, 1 MHz switching, and 2100 W/in³ power density.

Navitas says the design removes the need for a traditional 48V intermediate bus converter inside compute server trays, helping enable smaller and denser AI server power systems.
