SPACEX MAKES BIG PLAY TO BECOME A WIRELESS CARRIER

SpaceX will pay investment firm Grain Management about $8 billion in cash for US cellular spectrum licenses. The licenses will be for the 800-megahertz band, which is tailored for wireless service from cellphone towers rather than satellites. SpaceX says the new spectrum will help cover places satellite links can't reach. SpaceX still needs some terrestrial infrastructure to use the spectrum for mobile coverage.

THE START-UP THAT WANTS TO BUILD ‘MICROROBOTS' WITH AI

Atomic Machines is building AI technology that can discover new ways of designing extremely small devices. It is building an automated manufacturing system that turns computer code into a physical device. The company aims to revamp the field of microelectromechanical systems (MEMS), tiny devices made of both electrical and mechanical components. These devices are traditionally manufactured like computer chips, but this limits the possibilities of the technology to the physical properties of a semiconductor.

AMAZON BUILDS 1,000TH SATELLITE, WILL LAUNCH SPACE INTERNET SERVICE BY END OF YEAR

Amazon's Leo project is nearing several critical milestones. The company recently manufactured its 1,000th satellite and has reached the point where it can build a handful of satellites every day. The Vulcan's upcoming return-to-flight mission will carry Amazon Leo satellites, and another Vulcan rocket is currently being prepared to launch this year with more Amazon satellites. The company is just weeks away from offering a commercial space broadband service for the first time.

FIRST LOOK AT CLAUDE CODE MODS (SPOILER: YES, USE ONE NOW!)

You can now add panes, commands, and tool call rules to Claude Code with Mods. A mod is a plugin that changes how Claude Code looks and behaves. They can be used to add custom features to Claude Code. Mods run inside Claude Code, so they can do things that hooks, skills, status lines, and MCP servers can't, like redraw Claude Code's own interface, step into a tool call or request, and share data between hooks.

THE STATE OF AI REPORT 2026

Agents are now doing valuable work in software and science. Physical AI is learning how to act in the world, and access and control are becoming more essential. The frontier is now a three-lab race between Anthropic, OpenAI, and Google. Anthropic leads on Artificial Analysis' Intelligence Index, while Google leads on Arena's ranking of the answers people prefer.

ABSTRACT WARFARE: HOW TSMC MADE ITS OWN MARKET

The most important tech companies are much larger than their original markets. They not only expand their market, but make their own markets as well. These companies achieve this by attacking the abstractions their industry is built on. They change what it takes to participate in the industry and create shared infrastructure out of their competitors' businesses. This allows an ecosystem of new companies to form that both win in the market and are dependent on them.

OPENAI RELEASES FINDINGS ON 377 MATH PROBLEMS, FURTHER ROILING FIELD

OpenAI released hundreds of new findings spanning a wide range of topics including algebra, number theory, theoretical computer science, mathematical logic, and topology. These were solved with an internal model that has not been released publicly. There is debate on whether OpenAI's systems were employing creative thinking or simply completing the final steps of a proof after borrowing ideas from human mathematicians' work. OpenAI has provided summaries of how its models came up with the solution for 10 of the problems.

Anduril recently announced that it was awarded a contract worth up to $1.8 billion over five years to scale Lattice across the Army's Next-Generation Command and Control effort. The company plans to build the second of its Arsenal mega-factories in Baltimore. The mega-factory will be shipbuilding-focused and will, when operations begin in 2030, span over 2 million square feet of manufacturing space. The facility will be backed by $6.6 billion across both private investment and up to $2.9 billion through a submarine production contract with the US Navy.

A NEW TREND IN NUCLEAR ENERGY: SQUEEZING MORE POWER OUT OF OLD PLANTS

Building nuclear power plants takes a long time, so some companies are looking to upgrade older reactors to squeeze even more power out of them instead. These types of upgrades can cost billions and require approval by regulators, but they can often be completed in five years or less at a fraction of the cost of building a new plant from scratch. Many tech giants are eager to pay for these upgrades to power AI. Increasing production from existing nuclear plants will add an estimated 6,000 to 8,000 megawatts of electric capacity to US grids.

THE STATE OF THE TECH INDUSTRY IN 2026

The speed of change in the tech industry has never been this large-scale or fast. Practically nobody writes code by hand anymore. Assumptions about code output have broken, code reviews have become theatrical, and quality and reliability are down. Teams are still important, as is planning. Engineers will likely stop reading code altogether as companies start building a new type of AI infrastructure.

DECISIONS

OpenAI's Decisions API turns text and images into decisions that applications can use. It evaluates text, images, or both and returns typed answers 10 times faster than the Responses API. The Decisions API returns a probability that a condition is true, a choice from a fixed set, or a score against a rubric. These answers can be used to classify content, route requests, and prioritize work in an application.

HOW TO KEEP LEARNING IN THE AGE OF LLMS

We used to learn things by doing something wrong first and then taking a lesson out of it. LLMs make everything so fast that we don't want to spend time doing the wrong things, even though it's more beneficial in the long run. The struggle is how the brain actually learns new things. Use AI to help you think through problems rather than just giving you the answer.
