There you have it, $GOOGL Waymo to explore split with $UBER per FT. My view last year was that Uber partnering with Waymo was a bad choice… since Uber would just serve as a distribution funnel that Google needed as they scale up. And that $NBIS Avride, other neutral players, or vertical integration would be the optimal path forward. Now their own partner Waymo looks to be the strongest disruptor to Uber.

@Thomus0x eh, Rosenblatt June 30 note identified AMD as the likely first $AAOI CPO customer. I wouldn't quite say they aren't remotely close. $LITE / $COHR / $SIVE just look like your top 3 right now in terms of CPO laser visibility per the recent Morgan Stanley note.

Not exactly for $AAOI (they're working on CPO too, just a little further behind in commercialization). There's a podcast that featured the $SIVE CEO recently called: "Market Insights: Photonics & AI". Most interesting take was: "Pluggables will be around for the next 10 years". There's a lot of CPO + RNG/MRC optimization TAM cannablization arguments for pluggables recently, but looks like it's here to stay. And that there's going to be multiple architecture paths going forward (CEO also NPO alongside CPO as an major opportunity in the next 5 years). As for challenges: Vickram stated manufacturing capacity + availability of raw material is the main bottleneck. Likely referencing the existing bottlenecks with upstream CW laser ramp. From the podcast, seems like a large focus was on pluggable markets due to larger near-term TAM (which is understandable with $JBL + other players), with CPO being the north star. So it might be interesting if $SIVE M&A ambitions were to acquire more pluggable optical transceiver IP, like what $LITE did with Cloud Light. But TLDR: Lot of different paths moving forward, pluggable here to stay, CPO seems like North Star for where industry is heading. Feels like there's room for every qualified laser supplier given the industry demand is growing faster than what they can all collectively make.

Main thing was executive commentary on CPO thematically. Regarding $AMD + hyperscaler adoption + timelines. Checks were very positive for the CPO segment that sold off on delay news. And very positive for $SIVE in that segment, since they're the laser supplier for Ayar, $GFS, that are both linked with possible $AMD CPO routes. But couldn't get direct supplier confirmation since that's confidential.

From $AMD Advancing AI, channel checks: Helios networking partners told me they expect AMD to pursue CPO for future generations of Helios scale up networking. And expects other hyperscalers + industry to go down the CPO route. One AI infra executive at a company involved in a hyperscaler CPO programs said they had seen no indication of CPO scale up supply chain delays. Pushing back on recent 3rd party delay reports. This was informal commentary, not official AMD or partner guidance.

$INTC and $AMD to sign CPU LTAs with Chinese customers for AI DCs (Reuters). - Prices of some CPU products have risen more than 40% in China since the start of the year from sources. - Month-on-month increases topping 10% for some products CPUs were already a bottleneck, following CPU ratios due to AI inference... But the broader trend of LTAs seems to be appearing from: - Memory, with $MU, Samsung, $SNDK, and SK Hynix signing DRAM/NAND LTAs. - Photonics, with $LITE, $COHR signing EML LTAs. And recent Trendforce reports that $AMD and hyperscalers are now pursuing CW LTAs. And I'm sure there's many more from MLCCs to all the way to substrates. +1 for the bottleneck investors... hard to be a "bubble that pops" if you have take or pay demand spanning multiple years.

Just some notes from $TSLA transcripts: Elon Musk: "I think Optimus will be the biggest product ever" from Q2 earnings transcripts. Even from Q1, Elon Stated: "I think Optimus will be our biggest product. Not just Tesla's biggest product ever, but probably the biggest product ever. And I remain convinced of that conclusion". It's very rare to see such high conviction reiterated from Elon regarding humanoids both directionally and TAM-wise. In terms of upstream suppliers opportunities, Karn Budhiraj, VP of $TSLA supply chains stated: "We’re seeing the same level of investment going to memory and also new specific items like metal injection molded parts, flexible printed circuits, and all sorts of nonlinear technologies..." And that they had to build new supply chains from scratch. So would be interesting to look at for new supply chain supplier opportunities apart from the known ones. Just pulled older slides and it looks like capacity targets for Fremont are 1M and Giga Texas was 10M, so at scale, $TSLA seems to be the clear US leader. If you're looking at that S-Curve opportunity ramp. On a side note, Elon also gave a shoutout to $MU with likely reasonably priced LTAs, given his statement: "We really appreciate Micron making room for Tesla in the years to come and giving us actually a very significant allocation on reasonable terms given the pretty insane pricing of memory these days." (Just for structural memory demand). Elon also gave a shoutout to Panasonic which had invested many billions in increasing battery cell production (will need to do deeper DD into Panasonic after this), then Samsung and $TSM. Just takeaways from Tesla earnings TLDR: Elon tends to be directionally correct on where the future is heading, such as with EV or Space. He seems extremely bullish on humanoids.

Having an iota of reading comphrension helps a bit before commenting. AI Capex -> goes to upstream semis from memory, photonics, foundries, and others. These players are happy. $GOOGL itself is spending the money, so markets might not like that for them in specific. But it's positive to the players that receive that capital.

$GOOGL updates FY 2026 capex guidance: To $195B-$205B. Up from $180B-$190B. Google is also expected to significantly increase capex in 2027. This is perhaps the most bullish read through on upstream semis from a hyperscaler.

$GOOGL now has 950M monthly Gemini users and processes 22B API tokens/min. Compared to 750M back in February. Absurd growth adding 200 million more users in a few months. Kinda explains why they ran out of compute, then cut allocations to $META and others. Very unlikely AI capex will slow down given.

$GOOGL reported earnings today: EPS: $9.11 actual vs $2.91 expected - retail reactions to EPS blowout is kinda just accounting noise, since $SPCX, Anthropic, and others were likely large contributors. Revenue: $119.7B actual vs. $116.98B expected Google Cloud Revenue: $24.77B +82% Y/Y, vs. 63-65% expected ($22.2-$22.6B) - this is a very large beat and most material part so far. Cloud Operating Income: ~$8.81B, implying 35.6% margin vs. 32.9% Q1. Capex: $44.92B vs ~$44.15B (basically in line). So initial read through is Google Cloud accelerating growth with expanding margins is genuinely bullish for AI demand. Their former $180-$190B capex guidance is already extremely large, and as long as we get around these numbers in the earnings call + forward projections... Should be good to go for $LITE and the other optics/networking trade. (eg. last earnings, they said DC and networking would be ~40% of capex spend). Hyperscaler earnings transcripts are probably the most important thing to pay attention to with the AI capex trade. And that should be in 3 minutes.

$AMD to invest $5B in Anthropic. Anthropic in turn will sign a 2 GW deal to buy AMD’s latest chips, worth tens of billions of dollars. Looks like they’re copying the $NVDA playbook with Anthropic last year.

$SIVE CEO buys 70K shares today. I don’t really comment much on insider buying/selling, since it’s not exactly a fundamental catalyst. But given the company’s future is dependent on the CEO’s vision + execution, from NASDAQ listing, M&A, to scaling: It’s extremely positive to have Vickram be completely aligned with the shareholders

It's slightly more nuanced. Basically, $AMD SF event is tomorrow, Wed/Thurs (July 22, 23). From Jefferies client note, AMD is expected to provide additional disclosures around their likely scale-up CPO roadmap + MI500. If they confirm CPO route, would positive thematically since it's not just $NVDA forcing the transition. As for $SIVE, we'll get a better read if they're directly in AMD supply chains. Since right now, it's possible to map it through $GFS (reportedly involved in AMD MI500 CPO work) or AYAR (which AMD invested in). But no formal confirmations. So if you're turning in: - CPO thematic positive: MI500 explicitly commits to CPO/optical UALink. - AMD gives details using Ayar Labs or GF SCALE for MI500 CPO: That would be extremely positive for $SIVE, given they're the upstream laser supplier / reference laser. Currently, Blayne Curtis from Jefferies expect AMD to work with $ALAB on UAL and $AVGO on ESUN... but juicy details are here: "We are looking for whether AMD commits to a CPO based scale up solution and who supplies the optical engine" We'll get a broader read through on the supply chain come Wednesday/Thursday, too early to tell today.
