A Tweet About Marvell Job Postings Has POET Traders Talking - Here's the Context

If you follow POET Technologies (NASDAQ: POET) closely, you may have noticed some chatter on social media this morning. POET has been moving, and at least part of the conversation traces back to a tweet from a photonics-focused X account called @PhotonCap. We're not here to validate the thesis — but given that it's circulating and touching a name we've covered extensively, it seemed worth laying out the context for readers who want to form their own view.

This is one of those posts where we're reporting on what's being discussed, not weighing in on whether it's right.

What the Tweet Said

Original tweet: https://x.com/photoncap/status/2045914891941564679?s=46&t=9pnnFifDC3azhyKBqDhLIw

@PhotonCap flagged two job listings posted by Marvell Technology (NASDAQ: MRVL) in Santa Clara, and drew a connection to POET Technologies:

The first listing: a Senior Staff Silicon Photonics Packaging Engineer role calling for experience in "PIC-EIC co-design, Interposer, Optical PKG, 2.5D/3D PKG, wafer level PKG, OSAT."

The second: a Staff PIC Design Engineer position referencing "Photonic Fabric, PKG teams."

The account's conclusion: that Marvell appears to be hiring to accelerate its Celestial AI integration, and that the job description language points toward POET's technology. We'll note that @PhotonCap is a third-party account, and the connection drawn is speculative — Marvell has not confirmed anything publicly about POET.

Are These the Best AI Infrastructure Stocks Right Now?

The Background Traders Are Working From

For those less familiar with why some traders connect Marvell and POET at all, here's the short version.

In February 2026, Marvell acquired Celestial AI for $3.25 billion. Celestial AI was a pre-revenue company building photonic fabric interconnect technology for AI data centers. Some in the photonics community have noted that Celestial AI had previously worked with POET Technologies, reportedly using POET's Starlight external light source as part of its platform architecture. Celestial's founder was previously the Chairman of POET's board before leaving to start Celestial in 2020.

That history is what drives the speculation: when Marvell acquired Celestial, some traders began wondering what, if anything, that meant for POET's role as a potential supplier in Celestial's architecture. The job posting language — particularly "Optical Interposer" and "Photonic Fabric" — is what @PhotonCap pointed to as suggestive of that connection.

Again, none of this is confirmed. POET has not announced Marvell as a customer. Marvell has not commented on POET. What we have is a set of circumstantial signals that some traders find interesting enough to discuss.

Important Context on POET Itself

For anyone coming to this story fresh, a few grounding points on POET as a company are worth having.

POET is early-stage. Q4 2025 revenues came in at $341,000 — up meaningfully from prior periods, but still pre-scale by any commercial measure. The company has a $5M+ production order for its Infinity optical engines and expects to ship more than 30,000 units in 2026, which would represent a meaningful operational step. But the distance between current revenues and anything resembling a Marvell-scale commercial relationship is significant, and investors should weigh that accordingly.

MRVL is up significantly this morning on a fresh catalyst: The Information reported Sunday that Google is in talks with Marvell to co-develop two new AI chips — a memory processing unit designed to work alongside Google's existing TPUs, and a new TPU built specifically for AI inference. The discussions have not produced a signed contract, but the report sent MRVL shares up 6-7% in premarket. POET appears to be catching sympathy from that move. How much of today's action in POET is the @PhotonCap tweet versus the broader MRVL tape is genuinely hard to separate.

Why the Google News Adds Context

The Google/Marvell chip talks are worth noting in the context of the @PhotonCap thesis — not because they confirm anything about POET directly, but because they add another layer to the picture of how central Marvell is becoming to AI infrastructure across multiple hyperscalers.

They Said the Same Thing About Marvell?

The reported discussions describe Google building a multi-supplier architecture for its custom silicon — bringing Marvell in alongside Broadcom and MediaTek for different parts of the TPU program. Marvell's data center revenue reached a record $6.1 billion in its fiscal year ending February 2026, with existing custom chip relationships at Amazon, Microsoft, Meta, and now potentially Google. That's the ecosystem context in which the Celestial AI acquisition — and the POET connection traders are speculating about — sits.

None of that changes the speculative nature of the POET/MRVL link. But it does illustrate why traders are paying attention to anything that touches Marvell's AI buildout right now.

Why We're Covering It

We follow POET closely as part of our ongoing coverage of the optical interconnect and AI infrastructure space. When something is circulating that touches the name — even if it's speculative social chatter from a single account — we'd rather surface it with context than leave readers to encounter it without any background.

The broader ecosystem around AI photonics is real, active, and increasingly well-funded. POET's Optical Interposer platform has attracted credible partnerships and industry recognition. Whether any of that ultimately connects to Marvell's Celestial AI buildout in a revenue-generating way — and on what timeline — is an open question.

The tweet is an interesting data point. Whether it means anything beyond that is something each investor will have to decide for themselves.
