China's already-shipping CW lasers make Sivers' Chinese pluggable pipeline depend on price and qualification speed. Yuanjie says its 70/100mW chips, the classes Sivers lists, are in continuous large-volume delivery. It guides Q3 revenue up 265-293% and expects new capacity from end-2026 to early 2027, before Sivers' Q4 2027 Glasgow expansion. Yuanjie's 120/300/400mW parts remain in customer validation; Western hyperscaler qualification is probably where Sivers still has time. x.com  x.com  x.com  … Show more

Marvell risks paying a peak-scarcity price for Lumentum if optical supply catches up by 2028-30. The proposed ~$99B deal values Lumentum at roughly 20x guided annualized revenue and 58x estimated after-tax operating income, while Lumentum, Coherent and Chinese suppliers are adding laser capacity. The DSP-and-laser combination has strategic logic, but durable scarcity economics and Nvidia's response remain uncertain. x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

Sivers Semiconductors' AI optics rally prices in more than its photonics business has shown. About 75% of revenue is still wireless mmWave. Its 50-75mW CW lasers suit 400G and 800G but trail tier-1 rivals, making it a tier-2 spillover supplier like Applied Optoelectronics. Its small, old Glasgow fab has $50-150 million of potential laser revenue, with no sign of major expansion. Its multi-wavelength laser arrays for CPO are pre-revenue as Nvidia and Broadcom build their own. x.com 

Sivers Semiconductors' valuation is hard to justify even on its most ambitious targets for the next 1-3 years, given the margins it has and will have. Its most interesting angle is private companies such as Lightmatter apparently using its CW laser arrays, though that is not officially confirmed. Lumentum and Coherent, while not exact peers, are preferred. x.com 

Aeva's move into NPO/CPO is highly bullish for Sivers, again at the center of photonics through its CW-DFB lasers. Sivers is regarded as Aeva's laser supplier, and Aeva signed a joint development deal with an optical engine maker for a major hyperscaler, deploying in 2H27 and ramping in 2028. Per @ParadisLabs, Sivers partner GlobalFoundries expects silicon photonics revenue to more than double in 2026, with NPO ramping in 2027 and CPO in 2028. Jane Street closed its Sivers short. x.com  x.com  … Show more

Sivers Semiconductors' break-even hurdle puts market expectations far beyond what it can realistically deliver in the next 12 months. Revenue would need to multiply several times just to break even, before further R&D or foundry expansion spending. Its recent cash raise means near-term dilution is not expected, but much of the cash will go toward the foundry as quarterly losses continue. Hype could still lift the stock without improving the fundamentals, leaving huge short-term risk. x.com  x.com 

Sivers Semiconductors is still a startup, not a volume supplier, until it announces purchase orders with clear amounts and gives year-by-year revenue guidance. Its growing opportunity pipeline rests on management's discretion, not contracts, so it is noise. Management dodged forward guidance, reported no qualifications or production orders while CPO should grow triple digits, and conceded it trails Lumentum everywhere. Its margin target would be remarkable versus Coherent's ~40%. x.com 

Sivers Semiconductors' LiDAR design win is closer to generating revenue now that its customer has placed initial production orders. Shipments begin in Q4 2026; automotive and industrial programs target 2027 production. Sivers estimates $53M-$138M in lifetime revenue potential, not firm backlog; the initial order value is undisclosed and the program was announced in March. Repeat orders and shipment growth must convert potential into revenue; the market also wants profitability. x.com  x.com 

Sivers Semiconductors' $30M expansion of its Glasgow InP fab, targeting over 100M CW DFB lasers a year by Q4 2027, likely means hard dilution. As @PhotonCap notes, the plan shifts Sivers toward hybrid manufacturing, and its capacity target and customer ramps remain forward-looking rather than committed volumes. x.com
