POET's new supply and joint development deal with Lumilens, a $50 million initial order for optical engines and potentially $500 million over five years, places it at the next AI bottleneck. As GPU clusters scale to hundreds of thousands of chips, moving data between them at the speed compute requires becomes the constraint. Copper doesn't get there and photonics does, and POET's optical engine platform sits exactly at that intersection. x.com 

A potential Lumentum acquisition could let Marvell pair custom AI chips with the optical infrastructure connecting them. Following Celestial AI, it could become one of the few companies offering both, moving toward an AI-focused version of Broadcom; financing a deal this large remains a major concern. x.com 

POET Technologies is uninvestable because its management has lost the trust of the big players. In April its CFO leaked information that led to the cancellation of Celestial AI and Marvell contracts. Being early in interposers and packaging does not make it a co-packaged optics winner, as others will catch up. Its TFLN partner QCI trails Hyperlight and is stuck on a 6-inch line, with no 8-inch wafer demo yet to show it can scale. x.com  x.com 

Lumentum's 109% year-on-year growth and sold-out capacity through 2029 make selling its AI optics exposure questionable. Bloomberg reported Marvell is in advanced talks to buy it; the appeal depends on the price, especially when holders of an $80 billion Lumentum would become holders of a $320 billion-plus Marvell growing 37%. x.com 

Owning Lumentum's laser fab could secure Marvell's FY28 supply and hedge its DSP franchise as optical links shift to CPO. The rumored deal's strategy makes sense, but short-term pain is likely: at a 30% premium, roughly $17.5B in new debt and the rest in stock, rough math puts EPS dilution near 15%. It turns accretive only if Lumentum outgrows Marvell at today's guided rates for five or six more quarters, which looks achievable while the laser shortage lasts. x.com  x.com  x.com 

POET Technologies' Lumilens deal looks weak because Lumilens lacks the cash to pay for its purchase orders and needs POET's stock to soar to cash out. Lumilens has nothing in an ultra-competitive optics sector with China. Claims of billions in orders are false; any Amazon order depends on executing several steps first, while Coherent sells about $5B of optics after 30+ years with access to fabs, lasers and ICs. x.com  x.com 

POET's deal with Lumilens is a $500M validation that could move it from lab tech to commercial scale. The supply and joint development agreement starts with a $50M order for optical engines and could scale to $500M over five years, with samples in late 2026 and volume production in 2027. Its optical interposer integrates electronics and photonics in one chip-scale package, beating power-hungry pluggables. 2026 should be the year of validation, 2027 the year of revenue. x.com 

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 

POET Technologies' leadership is very good at hyping the stock, with two such cases in three weeks. It disclosed a new $5 million contract in the SEC filing that announced Marvell's order cancellation, and headlines ran with a "$500 million" Lumilens order that its own release put at $50 million with potential to scale. It is also oddly letting Lumilens buy deep in-the-money POET warrants at greatly reduced prices, not tied to a 30-day VWAP formula, unlike AMD's OpenAI deal. x.com  x.com  x.com 

POET Technologies is the upstream pick-and-shovel for Celestial AI's Photonic Fabric, which Marvell just acquired for about $5B. POET supplies the light source that powers it, and Marvell has the hyperscaler relationships with AWS, Google and Meta to deploy it at scale. Revenue is still early, but once Marvell integrates Celestial and ramps production orders, the market should recognize POET's value; Q3 or Q4 2026 could be the inflection, and patience is required. x.com
