@JoshMandell6 Thank you, Josh!

May the fourth be with you.

@vikramskr @NuttyCLD Isn’t the EV supply chain mostly using SiC?

I've started to broadly map out the power space with some good posts by @NuttyCLD First thing to understand is that the transition to 800V requires datacenters to be built from the ground up for true HVDC support. The mid-term approach will be to use power sidecars to handle large power levels per rack with high voltage. Longer term, datacenters will distribute power = no sidecars. The whole power situation can be monitored by looking at four umbrellas 1. WFE (Aixtron, Veeco) 2. Power Devices (Infinion, TI, Navitas, Power Integrations, ST, ON, Wolf) 3. Box builders (eaton, vertiv, schnieder electric) 4. Hardware providers (APH, TEC, Rosenberger) Most interestingly, the EV supply chain now has a massive AI DC pivot, and a lot of them will be looking to pivot.

@boymanrobshit You think Bloom Energy still has more upside?

For the record, I think the best answer is bloom energy. $BE Let’s bookmark this and time stamp it.

Power semis is 100% the most asymmetric information play right now. It’s 100% coming. $NVDA requirements are immutable but nobody has a fucking clue. I cannot wait for @insane_analyst first principles deep dive demo results. I don’t think people realize this has to ship late 2026 for rubin ultra - I think.

@vikramskr @semidoped Congrats Vik. Well deserved!

There has been such overwhelming support for me switching paths to do my own thing, aka my Substack newsletter and @semidoped podcast. I’m honestly appalled by the strong sense of community in this industry. I’ve even started to get many inbound requests for my boutique consulting work under the moniker — SemiExponent Thank you

The president resembles Adrian during a True North podcast.

@zephyr_z9 He was also talking about fungibility of cars.

Btw, he was talking about GM, Ford, European car makers losing market share in China

@AnthropicAI @zephyr_z9 @insane_analyst is this all going to be Trainium?

We're expanding our collaboration with Amazon to secure up to 5 gigawatts of compute for training and deploying Claude. Capacity begins coming online this quarter, with nearly 1 gigawatt expected by the end of 2026.

@insane_analyst @Philip_pan2008 Send me his deets, I will go say hi to him tomorrow at work 😂

@Philip_pan2008 Much lower level guy lol.

Just realized I know a guy who left $MRVL as the stock was bottoming to join $ALAB near the top. Frankly I thought Astera won Google memory/CXL rack program.

@jxnlco @pashmerepat Rpi. What’s the Rpi for?

@pashmerepat What is this?

Look what came in the mail

@insane_analyst @jukan05 I am actually surprised that Huawei and Nokia have better 5G. Samsung still uses AVGO/QCOM WiFi + BT right? At least that was the case when I was at QCOM.

@jukan05 Not really. Huawei and Apple and Nokia stronger on 5G

Looking forward to Apple and Nuvacore finishing off the worst semiconductor company.

Let Jon Stewart know if you want a nuanced bitcoin expert on his show. Like this post, and then comment on your favorite expert.

@dylan522p Thought you prefer Uber over Waymo..

Social media intern made me a terminally online LEGO 😭

@pitdesi @amitisinvesting Makes sense. Forgot about Meta’s MTIA

@arjun7965 @amitisinvesting I think NVIDIA + custom silicon

I added Meta ai to my Home Screen, finding it great for general queries. Surprised more people aren’t talking about it

@pitdesi @amitisinvesting any clue on the hardware they run on? TPU or NVIDIA?

@amitisinvesting Agree- and speed is really important for most of my queries!

@damnang2 @PhotonCap Haha 😆 I love ramen nagi! Westfield?

@arjun7965 @PhotonCap Ramen Nagi, I heard Zuckerberg is coming too.

I met up with @PhotonCap over ramen and had a really fun conversation. We might even end up building something exciting together in the future!?

@CitronResearch @aleabitoreddit did you see this lol?

Citron Short $AAOI- The anti-$LITE Two weeks ago $AAOI was $85. Today it's $140. $3.5B in market cap added on a random press release. This stock should trade back to $85 once the roulette wheel stops spinning (which would still put it above consensus) Let's be clear about something. Citron is not an AI bear. Long $GLW, the fiber backbone every hyperscaler buys more of regardless of which architecture wins. Respect $LITE, Nvidia's chosen partner with real profits and real backlog. GLW is reasonable. LITE is expensive. AAOI is delusional. And the customer tells you everything. LITE's anchor is Nvidia , $2 billion invested directly into their supplier, booked solid through 2028, balance sheet that could fund a small country. AAOI's anchor is Oracle , 30,000 layoffs, $100 billion in debt, negative free cash flow, and a flagship data center expansion that just fell apart over financing. One company picks winners. The other is desperately trying not to be a loser. ONE NUMBER ENDS DEBATE!! Nvidia at its peak as THE monopoly in AI chips with $200 billion in annual profits peaked at 40x forward earnings at the height of AI bubble euphoria. And Nvidia earned that multiple with 75% gross margins, monopoly pricing, and no real competition. AAOI trades at 112x forward earnings, nearly three times peak bubble Nvidia, with 31% gross margins, heavy capex, one customer, and zero pricing power. To justify 112x you need Nvidia-like margins. AAOI has commodity hardware margins that are one Innolight price cut away from making their already imaginary path to profitability a permanent moving target. You are paying beyond monopoly multiples for commodity economics , backed by the most leveraged, most financially stressed customer in the hyperscaler food chain. Could write pages about the Amazon warrants and the execution risks and accounting but why confuse an obvious story. Expensive has a defense. Delusional does not.
