What is Lightning AI's valuation?
Lightning AI was valued at $2.5B in January 2026, according to press reports (forbes.com). A private company's valuation is set when it raises money, so it can be well out of date between rounds.
That puts Lightning AI at number 32 of the 51 AI unicorns we profile, ranked by valuation.
How much funding has Lightning AI raised?
Lightning AI has raised $103M in total, as of November 2024 (prnewswire.com). The latest round was a $50M Strategic round in November 2024.

What is Lightning AI's revenue?
- More than $500M ARR in January 2026, the company said (voltagepark.com).
ARR (annual recurring revenue) is the yearly value of current subscriptions; annualized revenue scales a recent month or quarter up to a year. Neither is audited revenue. See what ARR is.

About Lightning AI
- Lightning AI, the company behind PyTorch Lightning, sells an AI cloud that combines software for training, deploying and running AI models with its own GPU compute, for developers, startups and enterprises. voltagepark.com
- Founded in 2019. forbes.com
- Founders: William Falcon. forbes.com
- In January 2026 Lightning AI merged with GPU cloud operator Voltage Park; the combined company kept the Lightning AI name, and Voltage Park's former CEO became president. CEO William Falcon told Forbes the merged company was valued at over $2.5 billion; this is a merger valuation, not a priced funding round. Jed McCaleb's Navigation Fund holds a significant stake in the merged company. Lightning was not acquired, so no acquisition field is set. forbes.com
- The over-$500 million ARR is for the merged company and includes GPU rentals booked through Voltage Park (Forbes); it is not Lightning's standalone software revenue. The ARR source is the merger announcement on Voltage Park's blog, now part of Lightning AI. forbes.com
- November 2024: $50 million equity investment from Cisco Investments, J.P. Morgan, K5 Global and NVIDIA, with no lead named, bringing total funding to $103 million. Forbes later said the company had raised over $100 million. prnewswire.com
- Series B (June 2022, when Grid.ai rebranded as Lightning AI): the company's page says the $40 million round was led by Coatue with participation from Index Ventures, though another line on the same page says it was led by Coatue and Index Ventures. lightning.ai
