L&T to set up India's largest Nvidia B300 AI factory for Together AI
L&T’s Vyoma.AI will build a 10,000-GPU Nvidia B300 AI factory at its Chennai data centre campus for US-based Together AI. Vyoma says the order is worth Rs 10,000-15,000 crore and will support training and inference for Together AI’s AI-native cloud platform. L&T earlier agreed to transfer its data centre and cloud business to Vyoma.AI for Rs 1,400 crore.
How this was made

The 30-second read
Why it matters
The disclosed single-cluster AI factory order (10,000 Nvidia B300 GPUs) and its stated value range provide a concrete datapoint for AI infrastructure demand and L&T’s execution in that segment.
Market read
Traders may view this as incremental confirmation of large-scale AI infrastructure demand and L&T’s ability to win sizable AI data-center orders.
What to watch
The article does not specify contract terms, payment schedule, margins, or commissioning timeline for the 10,000-GPU cluster, which are key for trading the equity response.
Background
Vyoma.AI is described as L&T’s data centre business, and the article frames the B300 factory as part of a gigawatt-scale AI infrastructure rollout at Chennai.
Market effects
Reinforces demand for AI data-center buildouts and accelerated computing infrastructure in India, potentially supporting broader AI infrastructure supply-chain sentiment.
Highlights Chennai as a gigawatt-scale AI infrastructure hub, which may attract follow-on hyperscale and enterprise AI workloads.
Signals continued global AI cluster buildout using Nvidia B300 systems, supporting the narrative of sustained AI hardware and networking demand.
Counterpoint
The headline deal size may not translate into near-term earnings impact if revenue recognition is back-end loaded or if capex and operating costs are heavy.
