Today, @TIME featured our self-driving lab on its 2026 Best Inventions list. Radical's self-driving lab discovers and develops novel materials at the speed of AI, enabling 10x more material discoveries per scientist. By combining AI, robotics, and experimental data, our high-throughput system can unlock advanced materials for new technologies. We are transforming how the world does science. #TIMEBestInventions time.com/collection/best-inv…

Cellular covers about 15% of Earth's landmass. Everything past that has meant hardware too expensive to justify tracking. Today, we're opening satellite coverage to Bluetooth devices, plus a $200M Series C, crossing unicorn valuation. @sana_pashankar at @Bloomberg has more.

RAI-939 outperformed industry-leading aerospace material C103 by 125x. In a head-to-head torch test, Purdue Applied Research Institute confirmed that Radical AI’s RAI-939 sample exhibited superior environmental survivability to C103. C103 has been in use since the Apollo program, but its performance limitations and constrained supply have fueled a decades-long search for a replacement. Our lab discovered that replacement in just 16 weeks. Now, we aim to scale up production of the alloy to make bigger components.

Moments ago, Valar Atomics took Ward 250 critical for the first time. This fulfills President Trump’s EO 14301, which called for 3 advanced reactors to go critical by July 4th. This is our second criticality as a company, and an important step toward our goal of power by July 4.

The most important industries all come back to one core thing: materials science discovery. And the experimental data needed to move them forward is immensely hard to capture. With AI, new possibilities emerge.

Introducing Arc – the world’s first space-based delivery vehicle. Arc enables the on-demand delivery of cargo and effects to anywhere on Earth in under an hour, and offers unparalleled hypersonic testing capabilities. Arc reshapes defense readiness by enabling access to anywhere on Earth in under an hour – allowing for the rapid delivery of mission-critical cargo and effects to austere, infrastructure-limited, or denied environments. This capability establishes space as a new global logistics domain, introducing unprecedented speed, reach, and resiliency for national security. Arc features a versatile payload bay designed to accommodate a wide range of mission-critical cargo and effects. When launched to low-Earth orbit, Arc vehicles will form constellations of varying sizes and locations tailored to each customer’s needs. When called down on demand, Arc spacecraft descend from orbit, maneuver through hypersonic reentry, and touch down safely under parachutes – all autonomously.
