The company said the influx of new orders could translate into a $75 billion (around €70 billion) in revenue, and it's feeling chirpy enough to lift its 2028 market forecast for these tailor-made AI chips. That puffed up the share price by more than 7 per cent on 18 June, as the cocaine nose jobs of Wall Street lapped it up.

It seems likely that the new chips will be churned out by TSMC, adding more rocket fuel to TSMC's advanced process line.

Marvell as the world's sixth-largest IC designer has carved itself a decent slice of the custom AI chip pie, leaning heavily on TSMC to get it done. The rumour mill places Marvell as one of TSMC's top 10 customers and one of just two key names pushing co-packaged optics.

Previously, Marvell rolled out a data centre chip built using TSMC's 3nm process and announced that it would ride that down to the 2nm node too. As Marvell's custom AI chip empire grows, it is chucking more and more cash into TSMC's advanced fabs.

Cloud service providers are no longer content with buying off-the-shelf kit from outfits like NVIDIA or Supermicro. They want their own bespoke silicon, which is helping firms like Marvell ride the wave.

According to Marvell, its data centre addressable market stood at $21 billion last year. It was expecting that to hit $75 billion by 2028, but now it reckons it'll hit $94 billion with a compound annual growth rate of 35 per cent.

Customised accelerated computing is set to be the main driver, with Marvell forecasting a 53 per cent compound growth rate in that segment, faster than networking or storage. Its market share in that space could jump from less than five per cent in 2023 to 20 per cent by 2028.

The top four US hyperscalers, Amazon, Microsoft, Google and Meta, are forecast to fling $327 billion into capex this year, up from $153 billion in 2023 and $248 billion last year, according to Marvell. Emerging players and state-funded AI projects are also expected to get in on the action.
