NTT
Japanese telecom giant running global data centers, submarine cables, and NTT DATA consulting.
On the record
Checkpoint: FY2026 quarterly profit tracking against ¥980B guidance, down from ¥1,037B
The call
NTT's cables and data centers are hard to replace, but its consulting arm is getting squeezed by AI just as the market starts punishing profit over revenue.
NTT owns massive physical infrastructure: over 1,100 megawatts of data centers and 125,000 kilometers of underwater cables that took decades to build and are hard for competitors to replicate quickly. However, the company makes money two ways. Its infrastructure business benefits from AI companies needing server space and connectivity, but its consulting and software services business (NTT DATA, worth about $30 billion) is getting squeezed because AI tools can now do work that human consultants used to do, and cloud companies like Amazon Web Services, Microsoft Azure, and Google Cloud offer similar services cheaper. The critical question over the next year or two is whether profits from the data center side will grow fast enough to make up for the money being lost in the consulting side, because right now the company is guiding for lower profits despite record revenue, which is what spooked investors in May 2026.
Why
01
AI pressure: AI coding and consulting agents (general AI productivity tools). AI agents cut hours needed for NTT DATA's consulting and systems integration work, squeezing that $30B unit's margins even as revenue holds. Could AI do the core job? Only partly.
02
Bigger players: AWS, Microsoft Azure, Google Cloud. Hyperscalers already own cloud computing outright, NTT holds under 1% share there and instead rents them raw data center space. Could a giant copy it? No, they are blocked.
03
What protects it. Japan's NTT Law, 34% government ownership, and 1,100+ MW of data centers and submarine cables that take years to replicate.
What would change this call
NTT's quarterly profit reports through FY2026/2027 versus the ¥980B guidance. Shows whether the margin decline from record revenue is a temporary dip or a sustained trend.
Hyperscale colocation deals (like the 130MW and 115MW US agreements) reporting actual realized margins. Reveals whether data-center leasing is a profitable growth line or low-margin commodity business.
Any further NTT Law revision or government stake-sale debate in Japan's parliament. Indicates whether NTT's regulatory-protected domestic moat is eroding.

Key numbers
- FY2025 revenue ¥14.41 trillion, up 5.1%
- FY2026 profit guided down to ¥980B from ¥1,037B
- 245MW+ new hyperscale colocation deals since Dec 2025
Named risks
- FY2026 profit guided down to ¥980B despite revenue growth, signaling margin compression.
- Political push to abolish NTT Law or force government stake sale creates regulatory uncertainty.
- Power-grid and supply-chain constraints could cause data center capacity crunch by 2030.
- AI substitution compressing margins in NTT DATA's SI and consulting workflows.
- Negligible cloud IaaS market share (under 1%) versus dominant hyperscalers.

Questions people ask
- Is NTT profitable in 2026?
- Yes. NTT Group posted record profit of ¥1.037 trillion for FY2025 ended March 31, 2026, but its own FY2026 guidance projects profit falling to ¥980 billion despite revenue rising to ¥15.06 trillion, a guidance issued May 8, 2026 that dented the stock.
- Could AI replace NTT?
- AI threatens routine coding, IT support and templated consulting inside NTT DATA's services arm, but cannot replicate NTT's physical assets: 1,100+ MW of data centers and roughly 125,000km of submarine cable, per NTT's own report dated June 29, 2026.
- Who owns NTT?
- NTT, Inc. trades on the Tokyo Stock Exchange as 9432, but Japan's Ministry of Finance retains about 34.25% ownership under the NTT Law, a stake tied to ongoing political debate over privatization, per Wikipedia data as of July 21, 2026.
- Who is NTT's biggest competitor?
- In cloud infrastructure NTT is a marginal player, holding under 1% IaaS share against AWS (about 28-30%), Microsoft Azure (about 20-21%), and Google Cloud (about 12-14%) as of July 9, 2026; domestically KDDI, SoftBank and Rakuten oppose NTT's regulatory advantages.
- Did NTT DATA go private?
- Yes. NTT Corp fully acquired NTT DATA Group via a ¥2.37 trillion (about $16.5B) tender offer, and NTT DATA Group delisted from the Tokyo Stock Exchange on September 26, 2025, becoming a wholly owned subsidiary.
- How big is NTT's data center business?
- NTT Global Data Centers operates over 1,100 MW of IT power capacity across roughly 95 to 160+ facilities worldwide as of March 3, 2026, and NTT itself claims third-largest global provider status, though independent rankings place it closer to 5th-7th.
