Voltage Park

Voltage Park

Voltage Park is a GPU cloud that rents NVIDIA H100 and Blackwell clusters for AI training and inference, either on-demand by the hour or on longer dedicated-reserve contracts. Voltage Park is unusual in its ownership: it was funded by the Navigation Fund, a nonprofit endowment created by Stellar and Ripple co-founder Jed McCaleb, and its profits flow back to that nonprofit. The company owns its hardware, around 36,000 Hopper, Blackwell and Grace Blackwell GPUs, connected with Quantum-2 InfiniBand and offered as bare metal. In January 2026 Voltage Park completed a merger with Lightning AI to form a combined AI cloud, though the Voltage Park brand and product still operate.

Production credibility: Voltage Park was launched in October 2023 with roughly $500 million in initial funding from the Navigation Fund, a 501(c)(3) nonprofit endowment founded by Jed McCaleb (co-founder of Stellar, Ripple and Mt. Gox); Voltage Park is structured as a subsidiary of that nonprofit, so its profits go back to the fund. It initially bought 24,000 NVIDIA H100 GPUs and now operates about 36,000 Hopper, Blackwell and Grace Blackwell GPUs across multiple US data centers. On January 21, 2026, Voltage Park completed a merger with Lightning AI; the combined company is valued at over $2.5 billion with annual recurring revenue reported above $500 million. William Falcon (Lightning AI) is CEO and former Voltage Park CEO Ozan Kaya became President. Voltage Park advertises on-demand H100 nodes from $1.99/hr, up to 3,200 Gbps of Quantum-2 InfiniBand bandwidth, and 99.982% uptime on a Tier 3+ architecture. Named users include Cursor, Phind and Caltech researchers.

Key Features

• On-demand NVIDIA HGX H100 nodes, self-serve and bootable in about 15 minutes, from $1.99/hr
• NVIDIA Blackwell and Grace Blackwell GPUs available alongside Hopper
• Bare-metal access for direct hardware control during large training runs
• Up to 3,200 Gbps aggregate bandwidth over NVIDIA Quantum-2 InfiniBand
• Dedicated Reserve contracts (12+ months) for committed, long-term capacity
• Company-owned hardware across multiple US data centers rather than resold capacity
• Tier 3+ data center architecture with a stated 99.982% uptime
• No long-term commitment required for on-demand usage

Ideal Use Case

ML teams use Voltage Park to spin up bare-metal H100 clusters on-demand for training and fine-tuning runs without signing a long contract, or to lock in dedicated reserve capacity for sustained production inference.

How Voltage Park differentiates

Against CoreWeave, Lambda and Together AI, Voltage Park's distinguishing trait is its nonprofit ownership: it sits under Jed McCaleb's Navigation Fund, and profits return to that endowment rather than to outside venture investors. Like Lambda, it leans on transparent hourly pricing (from $1.99/hr) and self-serve bare metal, which suits teams that want to start a run quickly. Compared with CoreWeave's very large reserved deployments, Voltage Park is friendlier to on-demand bursts. The key caveat for buyers is the January 2026 Lightning AI merger: the two now operate as one company, so the long-term roadmap is shared with Lightning's software platform. Its GPU fleet is also smaller than the biggest neoclouds, so very large reservations may need to be scoped.

FAQ

Q: Who founded and funds Voltage Park? A: Voltage Park was funded by the Navigation Fund, a nonprofit endowment created by Jed McCaleb, co-founder of Stellar, Ripple and Mt. Gox. Voltage Park is a subsidiary of that nonprofit, so its profits flow back to the fund. Ozan Kaya led it as CEO before the Lightning AI merger.

Q: How much funding does Voltage Park have? A: It launched in October 2023 with roughly $500 million from the Navigation Fund and bought 24,000 NVIDIA H100 GPUs. After merging with Lightning AI in January 2026, the combined company is valued at over $2.5 billion with reported ARR above $500 million.

Q: Did Voltage Park merge with Lightning AI? A: Yes. Voltage Park and Lightning AI completed a merger on January 21, 2026 to form a combined AI cloud. The Voltage Park GPU product and brand still operate, with William Falcon as CEO of the combined company and former Voltage Park CEO Ozan Kaya as President.

Q: How much does Voltage Park cost? A: Voltage Park lists on-demand NVIDIA H100 nodes starting at $1.99/hr with no long-term contract, plus Dedicated Reserve contracts of 12 months or more for committed, long-term GPU capacity.

Q: Voltage Park vs Lambda: which is better for GPU rental? A: Both offer on-demand NVIDIA H100 bare metal with transparent hourly pricing. Voltage Park owns its hardware under a nonprofit endowment and is now merged with Lightning AI's software platform; Lambda is an independent GPU cloud. Compare GPU availability, regions and reserve terms.

tl;dr

Voltage Park is a GPU cloud renting NVIDIA H100 and Blackwell clusters on-demand from $1.99/hr or on dedicated reserve, backed by Jed McCaleb's nonprofit Navigation Fund. It owns ~36,000 GPUs and, in January 2026, merged with Lightning AI into a combined ~$2.5B AI cloud.
