Marvell Technology is in advanced talks to acquire Lumentum Holdings, a maker of lasers and optical components for artificial intelligence data centres, Bloomberg reported on Wednesday, citing people familiar with the matter. A deal could be announced as soon as next week — but no final agreement has been reached, and the talks could still change or fall apart.
The $83 billion figure, explained
Early coverage described the deal as worth about $83 billion. That figure needs correcting: $83 billion is Lumentum’s market value at Wednesday’s close, according to Bloomberg, while Marvell is worth about $221 billion. No purchase price, premium, or cash-and-stock mix has been reported. Treating the market value as the deal price would overstate what is actually known — and this article does not do so.
Market reaction
Investors reacted in opposite directions in extended trading after the report: Lumentum shares rose sharply while Marvell shares fell. Reports differed on the exact size of the moves as after-hours trading progressed, so this article reports the direction rather than pinning a single percentage that later reports revised. The split is a familiar pattern for a large acquisition by a buyer whose own shares look expensive: the target rises on takeover hopes while the buyer falls on concerns about price, execution and regulatory review.
Why Marvell wants Lumentum
The deal is about the plumbing inside AI clusters. Lumentum makes the lasers, photonic integrated circuits and high-speed transceivers that move data between graphics processors inside AI data centres. Marvell makes digital signal processors. Combined, the two would cover more of the link between chips as the industry shifts away from copper connections for GPU-to-GPU links and towards optical ones. Marvell already buys lasers from Lumentum, so ownership would bring a key input in-house at a moment when high-performance optical components are a bottleneck for scaling AI infrastructure. Lumentum also counts Nvidia as both a customer and a $2 billion shareholder since earlier in 2026 — a wrinkle, since Nvidia is a rival of Marvell in custom silicon.
The wider AI dealmaking wave
The talks fit a broader blitz of AI-infrastructure dealmaking as investors bet on scaling up data-centre capacity. Marvell itself agreed in December 2025 to buy photonics startup Celestial AI for $3.25 billion in cash and stock, rising to $5.5 billion if revenue milestones are hit, according to AI Weekly’s account of that deal. A Lumentum acquisition would be far larger and would test how much appetite remains for mega-deals in the sector.
What is not known yet
A great deal remains unreported: whether Marvell would pay cash, stock or a mix; what premium, if any, Lumentum shareholders would receive; what regulatory approvals would be needed; and whether either company will comment. The Bloomberg report relies on unnamed people familiar with private discussions, and neither company has been reported as confirming the talks. Until an announcement arrives, this remains a reported negotiation, not a done deal.
What happens next
If the timetable in the report holds, an announcement could come as soon as next week. Watch for three things: a confirmed price and structure, any statement from either board, and the market’s second verdict once regular trading resumes — the after-hours moves are only a first reaction.
FAQ
Has Marvell bought Lumentum? No. Bloomberg reports advanced talks only. No final agreement has been reached. Is the deal worth $83 billion? Not as reported. $83 billion is Lumentum’s market value; no purchase price has been disclosed. Why would Marvell buy an optics company? To own the lasers and transceivers that move data between AI chips, reducing reliance on outside suppliers as data centres shift to optical links. What could still stop the deal? Price disagreements, board or regulatory objections, or either side walking away — all common at this stage of private talks.
