When energy markets experience volatility and escalated demand, the solution is decentralizing the grid with massive sodium batteries and multiple types of power gen.
Peaks at the forefront of a decade long transition in energy markets and reindustrialization. Sodium/NFPP chemistry is the future.
Infinite is excited to back @peakenergytech Series B, a $108M capital raise to scale sodium-ion battery systems.
America’s new industrial era demands upgraded energy infrastructure to meet the needs of an electrified economy.
Their passively-cooled grid-scale battery is deploying to meet more than $1B in customer commitments.

As the US establishes sovereignty in core industries from manufacturing to energy, a new era dawns:
The Neoindustrial Age
Founders are applying hard science breakthroughs to critical industries, and industrializing the US with machine intelligence. The application of autonomy, AI, and first principles engineering is enabling a level of mastery over the physical world that has never been seen.
This inflection point will define the next decade as we see legacy industries, from transportation to defense completely redefined. This also gives rise to sectors that interlink atoms and bits - AI material science, advanced compute, and applied robotics. This will create growth and prosperity, while also opening space to redefine societal paradigms. This is the moment for humanity to dream, and to prepare to stand in awe of its capacity for change.

We are continuing to deepen our partnership with @Mach_Industries
Modern deterrence requires an industrial base that can build at the speed and volume the mission demands.

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.

BREAKING: @valaratomics has become the first startup in history to make nuclear electricity, powering an @nvidia Blackwell chip through its Ward 250 nuclear reactor. This marks the first time advanced nuclear power has powered AI.
The dawn of a new era of American nuclear energy.
@isaiah_p_taylor and the @valaratomics team have been relentless in pursuit of criticality and fast, scalable atomics. Enormous achievement, congrats!
Mach will be vital to the safety and future of free societies.
As an outlier in defense innovation, Mach has proven with unprecedented speed to flight, production trajectory, and contract success that rebuilding America's industrial base is of prime importance. The team's mission-first ethos drives this strategy with urgency and operational discipline.
BREAKING: @Mach_Industries secured a $300M Series C led by @InfiniteXYZ and @RibbitCapital, according to Bloomberg.

We are honored to lead @Mach_Industries $300M Series C alongside @RibbitCapital with participation from @khoslaventures, @bedrock, @sequoia, @winklevosscap, and @1517.
Mach is built strategically for the new era of modern defense. A vertically integrated, autonomy-defined defense manufacturer designed to produce, iterate, and deploy low cost autonomous systems at scale.
As global security demands shift from high-cost platforms to mass-producible systems, Mach is inflecting into technical maturity and production scale at a critical moment.
Our time on the ground with @ethanrthornton and the Mach team proved their dedication and talent. Their mission to defend free societies is based on core values, and has driven exceptional breakthroughs.
Proud to be leading their Series C at @InfiniteXYZ

.@SecScottBessent: "A nation that cannot manufacture, mine, ship, or refine its needs gradually cedes its strength and sovereignty to others. That is a dangerous dependency for any country; it is an unacceptable one for the United States of America."
