Good morning. The SpaceX S-1 is out — and it shows billions in losses alongside Musk's extraordinary ownership stake. Ozempic just got dramatically more powerful as medicine — a major review confirms it cuts heart attacks and strokes. Intuit is cutting 17% of its workforce. Raúl Castro has been charged with murder. And Jupiter's lightning is 1,000 times more powerful than Earth's. Happy Friday. Let's go.
⚡ BIG STORY
The SpaceX S-1 Is Out. Billions in Losses. Musk Owns 42%. The Valuation Story Gets Complicated.
SpaceX filed its public S-1 with the SEC Thursday — the first time the company has disclosed full financials in its 24-year history. The headline numbers: SpaceX lost $1.4 billion in 2025 despite generating $15.2 billion in revenue. Starlink contributed $8.3 billion of that revenue and is profitable on its own. The rocket launch business — which requires enormous ongoing capital expenditure — is what's burning the cash. Musk personally owns 42% of the company.
The 42% ownership stake is extraordinary for a company of this scale. When SpaceX goes public at the targeted $1.75 trillion valuation, Musk's stake would be worth approximately $735 billion — more than the entire market cap of any company on earth today except Apple and Nvidia. Combined with his Tesla and xAI stakes, Musk's total wealth at IPO pricing would approach $1.5 trillion, making him by far the wealthiest person in human history.
What the S-1 reveals about the business:
Starlink is the crown jewel: 8.3 billion in revenue, profitable, 5.6 million subscribers globally, and growing at 40% year-over-year. The satellite internet business alone would justify a multi-hundred-billion valuation
Starship is the cash furnace: SpaceX spent $4.2 billion on Starship development in 2025. The rocket has flown but has not yet generated revenue. It is a bet on future contracts — Mars missions, point-to-point Earth transport, and NASA's Artemis lunar lander
The xAI relationship: the S-1 discloses that SpaceX has committed $2.1 billion in computing infrastructure to xAI over the next three years — deepening the intertwining of Musk's companies in ways that will create governance questions for public shareholders
NexoBrief take: The SpaceX S-1 is the most-read financial document of 2026. The losses are real but explainable. The Starlink growth is genuinely impressive. The Musk ownership concentration is the governance question every institutional investor will have to answer for themselves. The roadshow starts June 8. Pricing June 20.

Ozempic Just Got Dramatically More Powerful as Medicine. The Review That Changes Everything.
A massive international review published Thursday — synthesizing data from over 100,000 patients across dozens of clinical trials — found that GLP-1 drugs (Ozempic, Wegovy, Mounjaro, and their class) significantly reduce the risk of heart attacks, strokes, heart failure, and premature death. The effect sizes are substantial: up to 20% reduction in major cardiovascular events in patients with obesity or diabetes, independent of how much weight they lost.
That last part is the scientific bombshell. Previous thinking was that GLP-1 drugs prevented heart disease by helping people lose weight, which in turn reduced cardiovascular risk. This review suggests the drugs may have direct cardioprotective effects — mechanisms that work on the heart and vascular system independently of weight loss. If confirmed, GLP-1 drugs are not just weight loss medications. They are cardiovascular drugs that also produce weight loss.
What this means commercially:
Novo Nordisk and Eli Lilly — the dominant GLP-1 makers — see their total addressable market expand dramatically. Instead of the obesity market (roughly 650 million adults globally), the addressable population now includes anyone at elevated cardiovascular risk — potentially 1.5 to 2 billion people
Insurance and Medicare coverage arguments change significantly. Regulators and payers have been reluctant to cover GLP-1 drugs purely for weight loss. Cardiovascular disease prevention is a different clinical category with different reimbursement logic
Intuit cut 17% of its workforce today — about 3,200 people — citing AI replacing significant portions of its workforce. The jobs-and-AI story and the health revolution story are happening simultaneously
NexoBrief take: The GLP-1 cardiovascular review is one of the most commercially significant medical findings in years. The drugs were already printing money. This finding expands the market by a factor of two or three — and gives every insurer a new reason to cover them.
🤖 AI TOOL OF THE DAY
Intuit Is Cutting 17% of Its Workforce. AI Replaced the Jobs. The CEO Is Unapologetic.
Intuit — the company behind TurboTax, QuickBooks, and Mint — announced Thursday it is cutting approximately 17% of its workforce, or about 3,200 employees. CEO Sasan Goodarzi said bluntly that the reductions are driven by AI systems now performing work that previously required human employees. He called it "redeploying" toward AI-driven roles. The company will hire about 1,800 new employees in AI-focused positions — meaning the net job loss is roughly 1,400.
Intuit is not the first major company to use AI as explicit justification for layoffs. But it is one of the most direct. Goodarzi didn't frame this as cost-cutting due to a downturn. He framed it as AI making employees unnecessary. That distinction matters — it's the first major CEO to use that language this explicitly, which will make this a reference point in every future AI-driven layoff announcement.
The numbers behind the announcement:
Intuit's revenue grew 15% last year — this is not a struggling company laying off workers due to financial distress. It is a profitable company eliminating roles because AI does them faster and cheaper
The 1,800 new AI-focused hires represent roughly 56% of the positions being eliminated — so for every 10 jobs AI replaces, Intuit is creating about 5.6 AI-era jobs. That ratio is the real data point
The LIRR strike this week, the Intuit cuts, and the Yann LeCun vs. CEO doom debate are all the same story: AI is restructuring the labor market faster than policy, education, or social systems can adjust
NexoBrief take: Intuit replacing 17% of its workforce with AI while growing revenue 15% is the clearest corporate demonstration yet of what economists mean by 'productivity gains don't automatically become jobs.' The gains are real. The distribution is uneven. The policy debate is not catching up.
🚀 STARTUP SPOTLIGHT
Narwhal Waves Can Trap Light Beyond Known Limits. The Physics Startup Race Nobody Sees Coming.
Physicists at Peking University published a discovery Thursday that sounds like science fiction: they found a new class of wave — dubbed 'narwhal waves' for their distinctive shape — that can confine light far beyond what conventional physics says is possible, without relying on metals or the material properties that normally set the limits for optical confinement.
The finding matters for a specific reason that connects directly to the most pressing problems in AI hardware: light-based computing. Confining light more tightly means smaller optical components, which means more powerful photonic chips in a smaller space. The Penn polariton breakthrough earlier this week showed that light-based computing at room temperature is physically possible. The Peking narwhal wave result shows that confining that light at scales relevant to chip manufacturing is also physically achievable.
The startup opportunity:
Photonic computing startups — companies building chips that use light instead of electrons — have raised over $3 billion in venture capital in the past three years. LightMatter, Luminous Computing, and Lightsynq are the leading players in the U.S.
LightMatter recently closed a $400 million Series C and is deploying its first photonic interconnect chips inside Nvidia's data center infrastructure — the first commercial photonic chip embedded in mainstream AI hardware
The narwhal wave discovery adds a new tool to the photonic chip design toolkit — a way to confine light more tightly than previously thought possible, which translates directly to faster and denser optical components
NexoBrief take: Two major photonic computing discoveries in one week — Penn's polariton and Peking's narwhal waves — is not a coincidence. It is the scientific community converging on a technology that is about to become commercially important. LightMatter's $400 million bet looks better with every new physics paper.
🌍 CURRENT EVENTS
Raúl Castro Is Charged With Murder. Jupiter's Lightning Is Extraordinary. Junk Food Rewires Children's Brains.
Raúl Castro charged with murder:
The 94-year-old former Cuban leader faces several criminal charges including four counts of murder — related to a 1994 attack on a humanitarian tugboat that killed 37 Cuban civilians who were attempting to flee the island. Castro has denied involvement. The charges were filed by a Spanish court under universal jurisdiction — a legal principle that allows courts to prosecute crimes against humanity regardless of where they occurred. It is the most significant legal action taken against a former Cuban leader in history.
Jupiter's lightning is 1,000 times more powerful than Earth's:
NASA's Juno spacecraft discovered that some lightning bolts on Jupiter release energy equivalent to millions of nuclear explosions simultaneously — up to 1,000 times more powerful than the strongest lightning on Earth. Scientists believe Jupiter's atmospheric chemistry and depth create conditions for lightning that dwarf anything in our own atmosphere. The finding is the most detailed characterization of Jovian lightning ever made.
Three more quick:
Junk food early in life permanently rewires the brain — new research shows that high-fat, high-sugar diets in childhood change neural architecture in ways that persist into adulthood even after switching to a healthy diet. The implications for pediatric nutrition policy are significant
A common pesticide is linked to hidden brain damage in children before birth — researchers studying New York City children found that prenatal exposure left measurable marks on developing brains. The pesticide remains in widespread use
Leucine — a nutrient found in protein-rich foods — can supercharge mitochondria by protecting crucial energy-producing proteins inside cells. A dietary intervention with direct implications for aging, athletic performance, and metabolic disease
NexoBrief take: Jupiter's lightning being 1,000 times more powerful than Earth's is the kind of number that stops you cold. The scale of the universe's extremes — compared to what we consider extraordinary on our own planet — never gets less humbling. Have a great weekend.
