Export controls on Rasa/NCI to halt China's InP substrate production would cause collateral damage to IQE and LITE, while controls on Ulvac and other chokepoints for humanoid production have less collateral harm.
Evidence & details
- +CPO TAM goes from $0 to $91B according to GS research.
- +Author successfully frontran the previous photonics supercycle with AAOI, LITE, AXTI.
- +Many players with little exposure to current cycle (like SIVE, SOI) become new dominant CPO players.
- +Markets typically price in 8-12 months ahead of mass production milestones.
- β‘Mass production start H2 2026 for scale out.
- β‘Scale up in H2 2027 driving massive growth.
- βExisting US players (LITE, COHR) have legacy pluggable revenue that may face cannibalization, limiting re-rating potential.

People wonder why I'm focusing on non-US markets recently. Why? CPO is my #1 thematic long. Markets don't know yet, the sudden paradigm shift in photonics... I was one of the only to frontrun the current supercycle in 2025 w/ $AAOI @ ~$30, $LITE ~$300s, and $AXTI at ~$13 onβ¦
Thesis: CPO (co-packaged optics) is the #1 thematic long with TAM going from $0 to $91B. New dominant players in non-US markets (Europe: SIVE, SOI) and existing US players (LITE, COHR) stand to benefit. Legacβ¦
@Jayden11129225 $LITE went from $2B to $80B in two years by owning the laser chokepoint for EML $AAOI went from $1.4B to $14B in one year by owning laser chokepoint for 800g/1.6T transceivers + assembly $SIVE is $1.4B today before CPO and owns the CW laser chokepoint. Sivers β¦
Thesis: SIVE is undervalued at $1.4B market cap, owning the CW laser chokepoint for CPO, analogous to LITE and AAOI which grew 10-40x by owning similar laser chokepoints.
@Bonek2801 Risk management purposes. Iβd rather hold 50% in Bitcoin around $70K than sit on cash to lower volatility. Also the downside risk of $VPG is $TSLA creating their own sensors and vertically integrating it away. Similar bear case with $GOOGL and OCS with $LITE though.
Thesis: Downside risk for VPG from TSLA vertical integration; similar bear case for LITE with GOOGL.
Weβre seeing third order effects in markets with $LITE, $AAOI, and photonics having a bloodbath, dropping 10%+. Itβs multifaceted, with sector drop from Sandisk -10%+ and others selling off as well. But my nuance take is that the entire Japanese supply chain will likely run outβ¦
Thesis: Japanese export controls on InP will cause supply chain constraints for western photonics players, affecting LITE, AAOI, COHR, and potentially exacerbated by AXTI's monopoly, leading to continued sellβ¦
@ManglaniAkshay @LogicalThesis So I actually like $COHR more than $LITE right now and sold my LITE positions at ~$385. I did some internal research the other day and found some potential issues but didn't publish it yet. That being said it's still a good long but not as high cβ¦
Thesis: Sold LITE positions at ~$385 due to potential issues found in internal research. Still considers LITE a good long but not as high conviction as NBIS.
@RyanMDorsey23 This is a research note on point failure of the entire AI buildout in $AXTI/China from both substrate production and laser-grade Indium Phosphide. Iβm not doing valuation analysis on individual companies But if this flow stops, $LITE, $COHR, $AVGO to $GOOGL, $MSFβ¦
Thesis: Failure of AI buildout due to Indium Phosphide bottleneck in $AXTI/China affects companies dependent on InP supply.
@VulcanMK5 Yep, $LITE and $COHR are amazing and are up quite a bit since they tons pricing power. Go few levels deeper into $AXTI (vertically integrated), Sumitomo -> Dowa, etc. the concentration risk + bottleneck flashes warning signs. With HBM, it was an investment opportβ¦
Thesis: Photonic supply chain bottleneck similar to HBM presents investment opportunity in vertically integrated small caps AXTI and SMTOY as hyperscalers hoard materials.
Bullish on photonics and laser exposure plays, with highest upside in SIVE.
source βReaffirms bullish view on laser/photonic companies $SIVE, $AAOI, and $LITE based on past performance and expectation of better macro environment.
source βToo many shorts on AAOI, LITE, SMH may be squeezed due to positive geopolitical developments.
source βList of 30 US stocks with brief bullish theses covering semis, AI, space, rare earths, etc.
source βPhotonics supercycle underway with AI-driven demand surge; Lumentum's order pipeline full through 2028, benefiting the trio of American photonics companies.
source βLITE's backlog extending into 2028 signals extreme demand and lack of capacity, which along with hyperscaler demand spillover, positions AAOI as the largest 800G/1.6T capacity in America with vertical integration; execution on capacity ramp is expected to drive significant revenue growth, supporting a $40B market cap target.
source βLITE sold out into 2029 with CPO mass production confirmed for H2 2026; NVDA upstream supply chain for CPO/photonics benefits.
source βReaffirms long-term bullish thesis on a basket of semiconductor and related stocks, noting that short-term entry points vary but overall market validation continues.
source βPhotonics supercycle with multiple architectural shifts. Beneficiaries include LITE, COHR for current cycle (still 50%+ upside), AAOI and JBL for transitional bridge, SIVE and POET for CPO future, AXTI for all cycles, and ALMU for future quantum dot packaging.
source βAI hyperscaler demand is causing widespread supply chain bottlenecks across semiconductors, materials, and infrastructure components, benefiting companies exposed to CPUs, semiconductor equipment, photoresists, grid components, optical modules, and photonics.
source βMetaphor describing supply chain for optical components: SIVE and LITE produce specialized components (blue/red lobsters), POET processes them, MRVL integrates and sells. Nvidia buying red lobsters (alternative supply) may push MRVL to buy directly from SIVE/LITE, bypassing POET. The situation is fluid.
source βLumentum is fully booked through 2028, especially with NVDA, and is well-positioned to benefit from the massive CPO TAM expansion ($15B to $154B). Long-term direction is bullish, though short-term price action is uncertain due to option flow and expected beat.
source βCPO names are incredibly bullish due to a massive supply-demand imbalance confirmed by $LITE CEO, with CPO scaling still in early stages.
source βLITE's admission of needing to buy CW lasers from competitors due to Nvidia-driven bottleneck elevates AAOI and SIVE, who have their own CW laser capacity and are not fully allocated to Nvidia.
source βCoherent CEO reaffirmed CPO as massive revenue driver with timeline for initial revenue in H2 2026 and scale-up in H2 2027, making it ideal time to frontrun CPO adjacent names like SIVE and LITE before market prices in the volume drivers.
source βAXTI's InP substrate is critical for optical buildout with LITE; going long AXTI despite risk because if AXTI fails, LITE and others also suffer, making the risk worth it.
source βBuy these stocks at the bottom for full supercycle exposure as markets are forward-looking and will price in future scaling from 2026 to 2028.
source βCPO (co-packaged optics) is the #1 thematic long with TAM going from $0 to $91B. New dominant players in non-US markets (Europe: SIVE, SOI) and existing US players (LITE, COHR) stand to benefit. Legacy pluggable revenue faces cannibalization, but pure-play CPO names will surge once mass production starts.
source βPhotonics supply chain entering supercycle with CPO as compelling theme; rotated from LITE/COHR into SIVE for greater upside.
source βExport controls on Rasa/NCI to halt China's InP substrate production would cause collateral damage to IQE and LITE, while controls on Ulvac and other chokepoints for humanoid production have less collateral harm.
