NVIDIA controls an estimated 81% of the AI data center chip market in 2026, according to IDC, and no other vendor holds more than about 10%. This report compiles verified AI chip market share figures from IDC, Gartner, WSTS, Counterpoint Research, CreditSights, and company earnings filed through mid-2026, covering vendor rankings, revenue, high-bandwidth memory, and the supply chain underneath.
AI Chip Market Share Statistics
Who Leads AI Chip Market Share in 2026?
IDC puts NVIDIA at roughly 81% of AI data center chip revenue in 2026. AMD, its share doubled since 2024, sits near 10%.
One methodology note applies to every table of this kind: estimates shift depending on whether internally deployed hyperscaler chips such as Google’s TPU are counted, since those chips generate no external sales.
| Vendor | Estimated 2026 AI Data Center Chip Share |
|---|---|
| NVIDIA | 81% |
| AMD | ~10% |
| Custom hyperscaler silicon (Google TPU, AWS Trainium, others) | ~5% |
| Intel (discrete AI GPUs) | Below 1% |

The gap narrows in percentage terms and widens in dollars, because the market itself grows faster than any share shift. A fuller three-way breakdown sits in this AI GPU market share comparison of NVIDIA, AMD, and Intel, which also tracks their gross margin spread.
NVIDIA vs AMD vs Broadcom: AI Chip Revenue Compared
Percentage share understates the revenue gap. NVIDIA reported $75.2 billion in data center revenue for the quarter ended April 26, 2026, up 92% year over year, within total quarterly revenue of $81.6 billion.
Inside that segment, data center compute reached $60.4 billion, up 77%, and data center networking reached $14.8 billion, up 199%, per NVIDIA’s Q1 FY2027 release. Full fiscal 2026 revenue was $215.9 billion, with data center sales of $193.7 billion, up 68%.
AMD reported $5.8 billion in data center segment revenue for Q1 2026 (calendar), up 57% year over year, on top of $16.6 billion for full-year 2025. Real growth, yet NVIDIA’s comparable quarterly line was roughly 13 times larger.
Broadcom sits in a separate lane, selling custom accelerators and AI networking silicon rather than merchant GPUs. Its AI semiconductor revenue was $8.4 billion in Q1 FY2026 (ended February 1, 2026), up 106%, then $10.8 billion in Q2 FY2026, up 143%, with Q3 guidance of $16.0 billion.
Nearly all of this silicon ends up on Linux hosts, a point covered in the cloud provider Linux usage breakdown, where Google Cloud runs 91.6% of its VMs on Linux.
How Big Is the Semiconductor Market Behind AI Chips?
Gartner’s preliminary 2025 results put worldwide semiconductor revenue at $793 billion, up 21%, with AI semiconductors accounting for nearly one-third of total sales. NVIDIA contributed over 35% of the industry’s 2025 growth, and AI processors alone exceeded $200 billion in sales.
WSTS raised its outlook twice. Its Autumn 2025 forecast called for $975 billion in 2026, up more than 25%; its Spring 2026 forecast now projects $1.51 trillion, up 90%, driven by memory prices.
| Product Category | WSTS Projected 2026 Growth (YoY) |
|---|---|
| Memory | ~250% (to more than $800 billion) |
| Logic | 37% |
| Microprocessors | 20% |
| Analog | 10% |
| Discrete semiconductors | 8% |
| Sensors and Optoelectronics | 3% |

For 2027, WSTS projects a further 27% expansion to roughly $1.9 trillion. Where those chips run day to day is tracked in these Linux data center statistics, since Linux held 44.8% of the server OS market in 2024.
HBM Market Share Behind AI Chips: SK hynix, Samsung, Micron
Every modern AI accelerator stacks high-bandwidth memory next to the logic die, so HBM is a second front in the AI chip market share contest. Counterpoint Research measured SK hynix at 53% of HBM revenue in Q3 2025, with Samsung at 35% and Micron at 11%.
For full-year 2025, IDC put SK hynix’s HBM revenue share at 63.2%, per the company’s SEC filing. Gartner reports HBM surpassed $30 billion in 2025 sales, reaching 23% of the DRAM market.
The next generation tilts the same way. UBS estimates SK hynix will supply roughly 70% of HBM4 for NVIDIA’s Rubin platform in 2026, and Goldman Sachs projects the company will hold above 50% of total HBM share through at least 2026, per SK hynix’s own market outlook.
Supply is spoken for. Micron said on its fiscal Q1 2026 earnings call that its HBM capacity is sold out through calendar 2026.
TSMC and Hyperscaler Capex in the AI Chip Supply Chain
Market share cannot shift faster than manufacturing capacity allows, and in 2026 that capacity runs through one foundry. TSMC’s Q1 2026 results, for the quarter ended March 31, 2026, came in ahead of its own guidance.
| TSMC Q1 2026 Metric | Figure |
|---|---|
| Revenue (USD) | $35.90 billion, up 40.6% YoY |
| Gross margin | 66.2% |
| Operating margin | 58.1% |
| 3-nanometer share of wafer revenue | 25% |
| Advanced technologies (7nm and below) | 74% of wafer revenue |
| Q2 2026 revenue guidance | $39.0–40.2 billion |
Source: TSMC Q1 2026 earnings release, April 16, 2026
TSMC also guided full-year 2026 revenue growth above 30% in US dollar terms, citing demand for leading-edge nodes in AI and HPC.
On the demand side, CreditSights raised its 2026 capex estimate for the five largest hyperscalers to roughly $750 billion in July 2026, up from about $620 billion in January and about $600 billion in November 2025. That implies growth of around 67% year over year, a third straight year above 60%.
CreditSights estimated about 75% of its earlier $602 billion figure, or roughly $450 billion, was directed at AI infrastructure. Capex intensity for 2026 runs at about 86% of sales for Oracle, 54% for Meta, 47% for Microsoft, 46% for Alphabet, and 25% for Amazon.
Which industries absorb this infrastructure is mapped in the Linux server market share by industry sector data, and the underlying platform trends appear in the Linux cloud infrastructure market share statistics.
FAQs
Who has the largest AI chip market share in 2026?
NVIDIA, with an estimated 81% of the AI data center chip market in 2026, per IDC. AMD is second at roughly 10%, and custom hyperscaler silicon accounts for about 5%.
Reddit threads often quote NVIDIA’s AI chip share at 90%. Is that accurate?
IDC’s 2026 estimate is 81%. Higher figures circulating on Reddit usually come from narrower denominators that exclude custom hyperscaler chips like Google’s TPU, so the definition drives the number.
Is AMD catching up to NVIDIA, as some Reddit investors claim?
In share terms, yes: IDC pegs AMD near 10% in 2026, up from about 5% in 2024. In dollars, no: NVIDIA booked $75.2 billion in data center revenue in its April 2026 quarter versus AMD’s $5.8 billion in Q1 2026.
How much AI chip revenue does Broadcom generate?
Broadcom reported $10.8 billion in AI semiconductor revenue for Q2 FY2026, up 143% year over year, and guided Q3 to $16.0 billion, driven by custom accelerators and AI networking.
How big is the HBM memory market behind AI chips?
HBM sales surpassed $30 billion in 2025, reaching 23% of the DRAM market, per Gartner. Counterpoint Research measured SK hynix at 53% of HBM revenue in Q3 2025, ahead of Samsung at 35% and Micron at 11%.
