Nvidia's Trillion-Dollar Chip Empire Under Siege: Squeezed by Customer In-House Designs and Legacy Rivals
Nashnova编辑部
Nvidia nearly doubled quarterly revenue to roughly $92 billion and still holds about 90% of the AI accelerator market, but its biggest customers are now building — and selling — their own chips, while AMD, Broadcom, and startups press from every side, narrowing the moat from both within and without.
Why is the biggest threat coming from Nvidia's own customers?
Amazon CEO Andy Jassy disclosed that its in-house chip business, if spun off, would top $25 billion in annual revenue, growing at triple-digit percentages.
Google signed a custom-chip deal with Marvell — a semiconductor firm specializing in bespoke silicon — and Anthropic poached a chip veteran from Google to start its own effort.
This means → the hyperscalers (Amazon, Google, and peers that build their own data centers) are no longer just Nvidia buyers — they are selling self-designed chips to third parties, stepping directly onto Nvidia's home turf.
How far have the old rivals and new entrants come?
AMD's data-center revenue doubled year-on-year to $6.7 billion last quarter; CEO Lisa Su projects the total AI accelerator market — chips purpose-built for AI workloads — will reach $1.4 trillion by 2030.
Broadcom and Marvell took a different path: instead of selling general-purpose chips, they custom-design silicon for hyperscalers like Google, carving out an independent growth lane.
Startup Cerebras Systems just unveiled a new computer it claims outpaces every existing product in AI inference; investors continue pouring billions into the space.
How is geopolitics reshaping the competitive landscape?
U.S. export controls block Nvidia from selling its most advanced products to China — but the same lock is forging new competitors.
Nvidia itself has acknowledged that Huawei and other blacklisted firms are closing the gap fast, developing products that compete directly.
In plain terms = the sanctions cut off Nvidia's sales channel but forced a domestic alternative into existence — the market did not disappear; it just switched suppliers.
How deep is Nvidia's moat right now?
Nvidia still commands roughly 90% of the AI accelerator market and has extended into software, networking, and other layers to lock in its ecosystem.
Yet Gabelli portfolio manager Hendi Susanto noted that Amazon and Google suddenly selling self-designed chips externally was a shift that "came quite fast" — faster than the market expected.
This means → the moat still stands, but the most dangerous diggers are not rivals — they are the very customers that write the biggest purchase orders every year.
A 15% price hike — confidence or catalyst?
Sources say Nvidia has told some of its largest customers that servers containing its AI chips will rise more than 15% in price.
This reflects Nvidia's still-strong pricing power — alternatives are not yet mature, so customers must keep buying in the short term.
In plain terms = the hike is a double-edged sword: it boosts margins today but hands customers the most direct reason to accelerate in-house alternatives.
How long can 90% market share hold?
The AI chip market is heading toward a trillion dollars; the pie is growing, but so is the number of hands reaching for it.
Customer self-design + legacy-rival expansion + startup disruption + geopolitics spawning domestic alternatives — four lines squeezing Nvidia's perimeter at once.
This means → the single number to watch over the coming years is that 90%: every percentage point it drops represents billions of dollars in orders flowing elsewhere.
