The market may still be underestimating Marvell as it becomes a key supplier of custom silicon and connectivity for the AI build-out. At its Investor Day, Marvell put its addressable market at about $400 billion by 2030, targeted about $20B of FY28 revenue and said revenue could reach $70-90B by FY31. Last quarter revenue rose 37% to $2.74B on AI and data-center demand, and Nvidia's Jensen Huang reportedly called Marvell the next trillion-dollar company. x.com  x.com 

Marvell's $70-90 billion FY31 revenue target looks credible: COO Chris Koopmans said key foundry, substrate and packaging suppliers get five-year forecasts and had already seen it before investor day. A $500 price target still looks too aggressive for now; Marvell must show it can grow its networking and photonics segment to deserve a safe price increase. x.com  x.com 

Marvell's ambitious long-range outlook is encouraging about hyperscaler and AI-lab spending plans, but hitting it depends on AI revenue and token consumption soaring through decade's end. Even if its FY28 estimates rise again, Marvell trades at a healthy premium to Nvidia and Broadcom, especially on a GAAP basis, and those two are growing fast too. x.com 

Marvell looks interesting at less than 30x calendar-2027 EPS against expected 60-70% annual EPS growth, but overpaying for Lumentum could drive its shares lower. Marvell could pay up to $110B, roughly a 30% premium; the stock-versus-debt mix is unclear, and Lumentum holders might own a third of the combined company. If the deal falls apart, Marvell could rise 10-12%. x.com 

Marvell is being repriced as a core AI infrastructure holding after record results, with the bull case shifting from custom silicon toward networking and optics. Fresh June targets run $321-$385, led by KeyBanc's Street-high $385 on data center networking, scale-up and the $3.25 billion Celestial AI optical acquisition; the $236 average target is lagging, not bearish. The catch: the stock already trades above that average, and KeyBanc calls the custom XPU business less durable long term. x.com 

Marvell is a loser from the AI-lab slowdown, because it can't earn premium margins if Nvidia and Broadcom also see a pause. Lab leaders including Elon Musk, Dario Amodei and Sam Altman have pivoted to warning that AI could kill you, which, with AI already polling badly, will make it much harder for AI to attract investment. x.com 

Marvell's new long-term model points to a $750-$900 stock by 2028-29. Management targets about $80B of revenue by CY2030, versus a $47B consensus, with a 55-60% revenue CAGR led by custom silicon growing 80% a year. Operating margins of 44-46% and opex growing at half the rate of revenue imply EPS above $30, versus $18 expected; 25-30x that gives $750-$900. Marvell has largely met its targets over the past decade, and the stock trades about 70% below its implied future value. x.com  x.com  x.com  … Show more

Marvell expects its revenue to grow tenfold in five years to $80B, driven by custom chips it builds for hyperscalers. Those companies design their own chips to reduce reliance on Nvidia and cut the long-term cost of off-the-shelf parts. The custom segment had no revenue two years ago and is expected to bring in $30B by 2031. x.com 

Marvell's management is running the stock as a pump and dump to move shareholders' money into their own pockets. Wall Street prices Marvell as an ASIC design house without realizing that ASIC design is just IT outsourcing. It is not a real CXL play either: CXL IP is sold by Cadence, Synopsys and Rambus with no moat, and Astera Labs, which builds the switches and software around CXL, is the only good CXL play. x.com 

Marvell builds the chips for the data-center pipes that AI keeps choking, and its numbers now show that thesis. Last quarter's revenue grew 36%. At 40 times forward earnings the stock is no longer cheap, so further gains must come from earnings growth. x.com
