Tesorb Signal: Tesla, SpaceX, and the Musk Companies

SpaceX just secured a $60 billion option to buy AI coding startup Cursor. We break down the deal structure, why xAI couldn't build this in-house, and what the price tag reveals about the state of Grok.

In June 2012, the first Tesla Model S rolled off the line at Fremont. Fourteen years later, the last one has too. We break down why Tesla is retiring the cars that built its reputation, what's replacing them on the factory floor, and what it tells us about the company Tesla is becoming.

SpaceX's S-1 filing reveals Starlink generated $11.4 billion in revenue last year, making it the financial engine behind everything Elon Musk builds in space. But one uncomfortable number shows where all that money is going.

It costs fifteen cents to move a fully loaded Tesla Semi one mile. A diesel truck? About fifty cents. We break down the math behind the Semi's cost advantage, real-world fleet data, and what it means for the trucking industry.

Every original co-founder of Elon Musk's AI company xAI has left. Now SpaceX operators are running the rebuild, with a $2 trillion IPO on the line. We break down what happened and what it means.

In an Oakland courtroom, the world's richest man took the witness stand and told a jury that artificial intelligence could kill us all. We break down the Musk versus OpenAI trial that just kicked off in federal court — why OpenAI was built as a nonprofit, why that model couldn't survive contact with reality, and what this trial could actually change about who controls AI.

The next-generation Tesla Roadster was unveiled as a prototype in November 2017 with production promised for 2020. Nine years and at least eight broken deadlines later, the car still doesn't exist. We walk through the full timeline of delays, the escalating performance claims, and what the Roadster saga reveals about Tesla's pattern of promising big and delivering late.

Tesla quietly disclosed a $2 billion acquisition of an unnamed AI hardware company, buried in a single sentence in its Q1 2026 10-Q filing. The deal was never mentioned on the earnings call. We break down what the filing actually says, what the deal structure reveals about the target, and why Tesla's AI spending now dwarfs its car profits.

SpaceX just landed a rocket for the six hundredth time. The next day, Blue Origin lost a customer satellite on only its third New Glenn flight. We break down what SpaceX's launch dominance looks like in numbers, what went wrong for Blue Origin, and why the gap keeps getting wider.

On April 10, the Netherlands became the first country in Europe to approve Tesla's Full Self-Driving system. We break down what's different about European FSD, why one small country could unlock the continent, and what it means for Tesla's global autonomy strategy.

Tesla's Q1 2026 earnings beat expectations with a $3 billion cash flow swing. But the real story is what management said next: FSD is now the product, the car is just the delivery mechanism. Plus the Hardware 3 bombshell, robotaxi reality, and a $25 billion spending plan aimed at AI and robotics.

SpaceX filed for an IPO targeting a 1.75 trillion dollar valuation and a 75 billion dollar raise. That would shatter every record in stock market history. We break down what Starlink's revenue actually supports, why Musk is giving retail investors 30 percent of the shares, the xAI merger, the new 60 billion dollar Cursor deal, and the risks nobody in the hype cycle wants to talk about.

Tesla just expanded its robotaxi service to Dallas and Houston, making four cities total. The stock surged 12%. But behind the headlines, the numbers tell a more complicated story. We break down the fleet size gap, the safety data, the pricing war with Waymo, and what it all means for the trillion-dollar race to dominate autonomous rides.

Tesla's Optimus robot is working on factory floors and posing at the Boston Marathon. But the real story isn't the robot. It's Tesla's plan to build a million of them a year.

Tesla, SpaceX, and xAI announced a twenty-five billion dollar chip fab and the semiconductor industry laughed. Then Intel signed on — and announced a gallium-nitride chiplet breakthrough the same day. Lena Ruiz on why Terafab isn't really a bet on chips, but on orbital AI compute.
