Last Friday, the US jobs report came out, and it was bad. Economists expected 84,000 new jobs in September. The actual number was 29,000. August had 162,000. The S&P 500 went up 0.74% that day. The Nasdaq hit a new all-time high. The Fed has been raising interest rates to fight inflation. Higher rates make borrowing more expensive, which slows the economy down and (eventually) cools prices. So the Fed is watching for one thing: signs the economy is slowing. A weak jobs report is exactly that signal. That's why traders read Friday's number as good news. Before the report, the market priced in roughly a 70% chance of another rate hike at the October meeting. After the report, plus a comment from the New York Fed's John Williams that there was no rush to hike again, that dropped to about 43%. It wasn't just jobs, either. Job openings came in below expectations, and consumer confidence dropped sharply. The whole picture points to a cooling economy. . A stock's value is basically what the market thinks all its future profits are worth today. When rates are high, money in the future is worth less in today's terms, so companies whose big profits are years away get hit hardest. That's tech. So when hike odds dropped, tech jumped the most. The Nasdaq is now up three weeks in a row, while the Dow actually finished the week down 1.3%. The part most people are missing Rates didn't fall. The 10-year Treasury yield closed the week at 5.26%, near its highest level in about 20 years, and it's up half a percentage point in just a month. The market didn't get good news. It got less-bad news. Fewer people now expect rates to go higher, but nobody is expecting them to come down soon. There are also some warning signs underneath. Inflation pressure in manufacturing jumped last month, which gives the Fed a reason to keep hiking anyway. And the extra yield investors demand to hold risky corporate bonds has widened seven times in a row, while stocks sit near record highs. When bonds and stocks disagree like that, someone is usually wrong.

Most people watch stocks. Not many watch bonds. But if you want to understand why the market sometimes drops for no obvious reason, bonds are usually where the answer is. Stocks and bonds compete for the same money When bonds pay 1%, nobody really wants them. Investors put their money into stocks because there's no better option. When bonds pay 4 or 5% with almost no risk, that changes. Now a safe asset is paying you a solid return, and stocks have to work harder to justify the risk. The way they do that is by getting cheaper. That's why the stock market can fall even when companies are reporting good numbers. Higher yields make money expensive Bond yields also set the cost of borrowing. When they go up, companies pay more on their debt and people take out fewer mortgages and car loans. Less spending means lower profits, and lower profits mean lower stock prices. Not all rising yields are the same If yields rise because the economy is strong, stocks can usually handle it. The dangerous version is when yields rise because investors are nervous about government debt or inflation. In that case, stocks and bonds can fall at the same time, and the usual "bonds protect you when stocks drop" idea stops working. What I'd watch - The 10-year Treasury yield, especially sharp moves - Credit spreads, which is the gap between what companies and the government pay to borrow. When it widens, trouble is often coming. - Weak demand at Treasury auctions The takeaway: the bond market sets the price of money, and every other asset gets priced off it. If you only watch stocks, you're missing half the picture.

Last Wednesday, the Fed raised interest rates by a quarter point, to 3.75%–4.00%. It's the first hike in three years, and the vote was unanimous. The surprising part: Kevin Warsh, the Fed chair Trump hand-picked earlier this year to bring rates down, voted for it. Why the Fed hiked Inflation is stuck. Prices are up 3.4% from a year ago, and inflation has been above the Fed's 2% target for five straight years. A big driver is oil. The conflict with Iran has kept energy prices high, and that feeds into almost everything else we buy. Warsh's explanation was simple: inflation is too high and has been for too long. Raising rates makes borrowing more expensive. When loans cost more, people and businesses spend less. Less spending is supposed to bring prices down. It's the Fed's main tool, and it's a blunt one. This is the part worth studying. The hike itself barely moved stocks, because everyone expected it. Stocks only sold off once Warsh started talking and hinted that more hikes could be coming. The 10-year Treasury yield pushed up near 5%, its highest level since 2007. Then on Thursday, stocks bounced right back. Oil got cheaper, bond yields came down, and chip stocks led the rally. What investors should take from this 1. Markets react to surprises, not news. The hike was already priced in. What nobody knew was how tough Warsh would sound. If you're trading on headlines, you're usually trading on information the market already has. 2. First reactions are often wrong. In 24 hours, Wall Street went from "the Fed is scaring us" to "good, the Fed is serious about inflation." Anyone who panic-sold on Wednesday sold into a one-day dip. 3. Watch what's actually driving inflation. Thursday's rebound didn't come from the Fed. It came from cheaper oil. If you want a clue about where rates go next, energy prices will tell you more than any press conference.

OpenAI filed confidentially for an IPO in June. Reporting put the potential valuation near a trillion dollars — one of the largest listings ever attempted. Last weekend Sam Altman told Fortune it's not happening in 2026. His words: going public right now would be ill-advised. Not because of the market. Not because of the valuation. Because of safety. He also said a 10% chance that AI causes human extinction this decade is unacceptable to him. That's the person who would have been ringing the opening bell. Every frontier lab has published safety commitments. Blog posts, responsible scaling policies, charters. None of it costs anything. You can write a safety framework on a Tuesday and ship a bigger model on Wednesday. This is the first time the position has shown up as a real cost. A listing that size is liquidity for employees, investors, and the company's compute bill. Postponing it is a decision with a price tag. Two days before the interview, Dario Amodei published an essay called "We Must Pace the Frontier," arguing the industry needs to deliberately slow capability gains so alignment work can catch up. Three steps: independent evaluators embedded inside the labs, coordination between US companies, then between governments. Anthropic committed to the first one unilaterally — outside evaluators get permanent, employee-level access to their systems. Three days before that, an Anthropic researcher resigned publicly, saying the labs are racing toward self-improving superintelligence and gambling with our lives. Altman named Dario directly and said he agrees. So the sequence is: researcher quits, Amodei publishes, Altman pulls the IPO. Not a coincidence, and not a reaction to markets. Critics point out Amodei's essay never defines what "slower" means. No threshold, no enforcement, no penalty. It's one company's voluntary pledge, dressed as an industry framework. And Anthropic is still marketing its own IPO for this fall. There's a reading where staying private is the convenient move regardless of safety. A public OpenAI has to justify every safety-driven slowdown to shareholders who own the stock. Private, Altman answers to almost no one. The stated reason and the self-interested reason point the same direction, which is exactly when you should look harder.
