Physical-AI startup Atoms raises $1.7B led by a16z

The round closed on July 22, 2026, as $1.7 billion in equity. Atoms did not disclose a valuation. Other equity investors include Bain Capital, Fifth Wall, Chemistry, K5 Global, SV Angel and Alpha Square Group. Uber is also in the round, nine years after Travis Kalanick left as its CEO. Bank of America, Goldman Sachs, Wells Fargo, JPMorgan and Barclays are named as debt partners, but the size of any debt facility has not been given. The money lands at the holding-company level, not in one division. The raise coincided with merging Kalanick's businesses, including CloudKitchens and the mining-automation firm Pronto, into a single equity structure with Food, Mining and Transport units. Atoms spent roughly eight years in stealth. Per its own pitch, it owns and operates its machines instead of selling them, which puts the capital burden on its own balance sheet. The round fits a funding surge. Crunchbase counted about $18.8 billion in robotics and physical-AI venture funding in the first half of 2026, already above all of 2025. For founders, the signal is that large checks are going to operators with real deployments in heavy industry. Investors are paying for owned-asset models and specialized machines, not only software or humanoid demos. Startups selling into mining, logistics or food should expect a well-funded competitor with its own fleet, and should be ready to show unit economics.
