THE 10 AM DROP: HOW JANE STREET BROKE BITCOIN'S PRICE

Beginning in late 2024 and accelerating through 2025, Bitcoin's price experienced sudden and sharp sell-offs every trading day at 10 AM Eastern, coinciding with the US stock market open. The drops were precise, algorithmic, and wildly disproportionate to the broader market conditions. They wiped out leveraged long positions, triggered cascading liquidations, and then reversed within hours. These dumps stopped the moment Jane Street had lawyers looking over its shoulder due to the Terraform Labs lawsuit, and they started again in Q3 2025 when the heat died down.

ANTHROPIC'S PENTAGON SHOWDOWN IS ABOUT MORE THAN AI GUARDRAILS

Anthropic has the most constrained use age policy of all of the AI companies working on US military applications. It has a host of limitations on the use of its technology intended to prevent broader societal harm that includes core tenets such as 'Do Not Develop or Design Weapons' and 'Do Not Compromise Computer or Network Systems'. However, there are signs that the company's safety commitments are slipping. The Pentagon's threat to potentially remove Anthropic from the supply chain could be almost fatal to the business.

ALPHABET-OWNED ROBOTICS SOFTWARE COMPANY INTRINSIC JOINS GOOGLE

Alphabet-owned robotics company, Intrinsic, is joining Google to unlock the promise of physical AI for a much broader set of manufacturing businesses and developers. It will remain a distinct entity within Google but work closely with Google DeepMind and tap into Google's Gemini AI models and cloud services. Intrinsic announced a joint venture with Foxconn in October that involves the two companies working together on general-purpose intelligent robots to transform how electronics are manufactured, with the goal of full factory automation. The company is now working towards those goals with closer collaboration with Google's AI prowess.

WAYVE, AN AI DRIVERLESS CAR START-UP IN EUROPE, RAISES $1.2 BILLION

Wayve has raised $1.2 billion in a deal that values the London-based autonomous vehicle software startup at $8.6 billion. The funding, which could grow to $1.5 billion if it hits certain performance targets, is one of the largest amounts raised by a European startup. Wayve expects to have its driverless taxis on the road for customers this year through a commercial trial with Uber. Consumer vehicles incorporating its technology will be available to buy by 2027.

TESTS ARE THE NEW MOAT

Software contracts, tests, and API surface area are becoming more valuable as AI becomes better at cloning people's work. This clashes with the incentives of commercialized open source work. Previously, the overhead of writing, understanding, and maintaining the code itself was important. However, clearly defining and communicating open source software's APIs makes it easier for AI to clone work.

SOFTWARE COMPANIES BUYING SOFTWARE: A STORY OF ECOSYSTEMS AND VENDORS

Several things are happening in software: a lot more startups with super-fast revenue growth are popping up, margins are thinner, engineering inequality is growing, and digital natives had a bunch of layoffs. This is all a direct corollary of the platformization of software, and it will continue. What's happening is expected - it just took some time to happen. The software industry is now much bigger than it was a decade ago, and AI is creating a ton of FOMO.

PRODUCTIVITY: THE EVIDENCE IS MIXED, BUT THE PATTERN IS CLEAR

AI increases productivity on well-scoped tasks where errors are detectable. This breaks down when tasks get harder. When AI agent output is scored algorithmically, it looks moderately capable, but when scored holistically, performance drops substantially. Estimates about AI's effect on productivity drop when task reliability is factored in.

TWO BELIEFS ABOUT CODING AGENTS

Most talented developers do not appreciate the impact of the intuitive knowledge they bring to their coding agents, and most of the work people are sharing are incredible personal tools, but they are not capital-P products.
