Marvell paid $3.25bn for silicon photonics maker Celestial AI to target market KeyBanc sees hitting $20bn by 2030

Two $30 billion figures run through this story and they measure different things. John Vinh's is a 2030 market: scale-up networking, about $20 billion of it optical and $10 billion switching ^[1]. Marvell's is the sum of its own revenue targets, roughly $12 billion in fiscal 2027 and $18 billion in fiscal 2028, and that sum covers the whole company ^[3]. The earlier version of the same guidance was about $20 billion for the two years ^[4].

Vinh's target went to $385, a 48% raise ^[2], so the number he carried before was near $260 ^[14]. Crypto Briefing's account leaves out Marvell's share price and the interconnect segment's current revenue, so the premium in that target and the dollar size of the 70% growth are both beyond what it shows ^[13]. Shares have climbed more than 180% in 2026 ^[10]. That puts the price at about 2.8 times where it started the year ^[19].

The two acquisitions together come to roughly $3.79 billion of consideration ^[15], for silicon photonics ^[6] and chiplet interconnect ^[7]. Against the $20 billion optical market Vinh dates to 2030, that is about 19% of a single year of it ^[16]. The guidance raise is the larger number: $10 billion of extra expected revenue across two years, a 50% increase on what Marvell had guided before ^[17]. Inside that, fiscal 2028's $18 billion sits $6 billion and 50% above fiscal 2027 ^[18].

The engineering case is the settled part. Copper links degrade over distance and throw off substantial heat at high data rates ^[12]. Near-packaged optics puts the optical components on a separate substrate close to the processor. Co-packaged optics integrates the transceivers onto the chip package itself. Both cut latency and power draw against pluggable modules sitting at the edge of a server rack ^[11].

Which supplier collects on that is a commercial question. Marvell has expanded its partnership with Nvidia to cover custom silicon, optics and NVLink, Nvidia's proprietary interconnect for linking GPUs in training clusters ^[8], and it has a multi-year supply agreement with Google, another large buyer of custom networking silicon ^[9]. Nvidia owns the specification Marvell is now selling into. If it integrates co-packaged optics itself, the expanded partnership caps Marvell's optical volumes.

I would weight the guidance above the market estimate: Marvell has put its name on $18 billion for fiscal 2028 ^[3], and the 2030 addressable market is a projection. The counter is that guidance two years out from a chip designer is itself a forecast of somebody else's capital spending, and the test arrives well before 2030. Fiscal 2027 interconnect growth below 70% ^[5], or an $18 billion fiscal 2028 in which custom silicon supplies most of the increment, would leave the optical case resting on Vinh's estimate alone.
