Reflection AI Secures $6.3B Chip Deal as Open-Weight Labs Challenge Closed Models

Published by James Harris on June 23, 2026June 23, 2026

Reflection AI, a two-year-old open-weight lab founded by former Google DeepMind researchers, has agreed to pay SpaceX $150 million per month for access to Nvidia GB300 chips at the Colossus 2 facility near Memphis, with payments starting July 1, 2026 and a contract that could run through 2029. If it holds, the deal totals roughly $6.3 billion, making it one of the largest infrastructure commitments by an open-weight lab on record.

The contract lands at an interesting moment for open-weight AI. The U.S. government recently banned Anthropic’s closed models Fable and Mythos, a decision that has pushed organizations to reconsider dependence on proprietary systems they cannot inspect or modify. That regulatory pressure creates a structural tailwind for labs like Reflection, which publish their model weights so developers and governments can audit and adapt them independently. The compute gap between open and closed labs has historically been the limiting factor, not the research talent, and a $150 million monthly hardware commitment is a direct attempt to close it. For context, Anthropic is paying $1.25 billion monthly for Colossus 2 access, and Google agreed earlier this month to $920 million monthly through the same end date, suggesting SpaceX is pricing Reflection at a discount relative to its closed-model tenants.

Elon Musk has already moved to frame the three-year terms as softer than they appear, pointing to the 90-day exit clauses both parties hold after the first three months.

SpaceX’s data center strategy is worth reading carefully. Colossus was built by xAI to run Grok, but the decision to rent excess capacity to outside labs, including Anthropic, Google, Reflection, and Cursor, which SpaceX is currently acquiring, transforms the facility into something closer to a commercial cloud provider with a very short tenant list. That concentration of frontier AI workloads under one roof, operated by a company with its own AI ambitions, raises questions that regulators have not yet publicly addressed. The xAI operation has already drawn federal attention over its Memphis power infrastructure, and adding more tenants at this scale will only intensify scrutiny of the site’s energy and permitting footprint.

The Nvidia backing of Reflection is also not incidental. As open-weight labs compete for hardware access in an environment where chip supply remains constrained, Nvidia has a direct commercial interest in seeing well-funded open labs secure long-term compute contracts. A Nvidia-backed startup locking in GB300 access through 2029 is as much a distribution story for Nvidia as it is a research story for Reflection. SPCX shares fell roughly 16.4% the day prior to this announcement, closing at $154.60, a reminder that SpaceX’s public market profile is still finding its footing even as the underlying infrastructure business compounds quietly.
