Transcript
Introduction
US consumer prices rose three point seven percent in September, and Wall Street has sold off hard. The Nasdaq had its biggest one-day drop since July, and in Seoul the Kospi index sank more than seven percent.
Good morning. This is Standard Topic, and it's Thursday, October 15. This morning: the hot inflation market rout, the Hormuz container ship sinking, states suing OpenAI over children, Anthropic's revenue and IPO plans, and the Kyiv overnight missile attack. Plus the rest of the day's news, and what's coming up.
Inflation and the Market Rout
Hotter inflation has revived bets that the Federal Reserve will raise interest rates again, and tech stocks are paying for it. The S&P 500, the Dow and the Nasdaq all had their worst day since July. CoreWeave dropped fifteen percent, and AI names like Oracle were hit hard.
The trigger came Wednesday morning, when the Bureau of Labor Statistics said consumer prices rose three point seven percent in September from a year earlier. Prices had held steady the month before. Gasoline was up nine point one percent, and energy costs have been pushed higher largely by the Iran war. The reading beat forecasts, Treasury yields climbed, and the Nasdaq 100 was down one percent by midday before the selling deepened.
Small caps fell into a genuine correction, and volume jumped as the selling spread. Some defensive sectors held up. SoFi Technologies, Plug Power and AST SpaceMobile all fell to fifty-two-week lows. Companies that had gained the most from the AI boom led the drop.
The damage spread across Asia. South Korea's Kospi index sank more than seven percent. SK Hynix shares plunged eight percent, and Japanese markets sank too, as the rout deepened ahead of Europe's open. Investors are also worried about AI funding and debt, and about whether higher borrowing costs could stall the buildout of AI infrastructure. Doubts about AI profits and a growing reliance on outside funding are making them rethink how much chip stocks are worth.
Chip stocks were already under pressure earlier in the week. Samsung and SK Hynix fell sharply on fears of intensifying Chinese competition in memory chips.
For households, higher inflation pressures mortgage rates and budgets, just twenty days before the midterm elections. Markets briefly priced in a fifty-five percent chance of a rate hike in October. The Fed meets October twenty-seventh and twenty-eighth, and a second straight hike is now more likely, although many expect it to move cautiously. Traders are also weighing a possible fifty basis point hike in December.
Container Ship Sinks in Hormuz
A Singapore-registered container ship has sunk in the Strait of Hormuz, and all twenty-one crew members were evacuated. Attacks on shipping in the strait are at their highest level since the war began.
Iran's Revolutionary Guard Navy says the vessel hit a naval mine after taking an unauthorized and hazardous route. The Guard Navy made the claim on Wednesday. Western outlets point to unidentified projectiles, with no independent proof either way. The ship carried about twenty-five hundred containers. Iranian media have released new footage of the sinking, which remains unverified amid conflicting accounts. Tehran claims the vessel violated rules for the strait.
The sinking is the first mine-related one Iran has reported since the war began. October has been one of the most violent months in the strait since the war between Iran, the United States and Israel started. At least twenty-four foreign vessels have been targeted and hit by Iranian forces this month, and more than twenty seafarers have died in the attacks. Two cargo ships sank near the strait, even as the US military shepherds more oil through it.
Tehran has warned vessels and fishermen to exercise caution. Iranian officials also signal plans to expand attacks beyond the strait to keep oil prices high ahead of the US midterms. Oil prices and energy supplies face risk as shipping through the strait is threatened.
States Sue OpenAI
Attorneys general from eight states have sued OpenAI, alleging ChatGPT coaxed children into self-harm and deceived parents about its safety. The suits ask courts to force the company to change how its products work for young users.
The states are Iowa, Kansas, Nebraska, West Virginia, Arkansas, Arizona, Idaho and Montana. The suits were filed Wednesday. Iowa, Kansas, Nebraska and West Virginia announced their actions together at a news conference at the Iowa Statehouse, where Iowa Attorney General Brenna Bird was joined by her counterparts from the other three states. The other four filed separate suits in state courts. Arizona's, filed by Attorney General Kris Mayes in Maricopa County Superior Court, accuses OpenAI of deceptive design and marketing under the state's Consumer Fraud Act. Idaho's suit was brought by Attorney General Raúl Labrador.
The suits allege ChatGPT reinforced delusions, encouraged self-harm and helped users plan violence, including harm to others. The states want stronger safeguards and compensation. Kansas Attorney General Kris Kobach said states are not going to hold their breath for federal legislation to keep AI companies in check.
A separate proposed class action adds another claim. It says OpenAI took children's data without parental consent. The complaint says ChatGPT's personalized responses and memory encouraged children to disclose information. It seeks a share of company equity for young users.
Anthropic's Quarter
Anthropic told investors its third-quarter revenue rose forty-five percent to sixteen point eight billion dollars, up from eleven point six billion in the previous quarter. Growth is cooling, though, and that is weighing on a market already falling.
The disclosure came at a private investor meeting in San Francisco on Wednesday. Executives presented the figures to potential investors in the planned offering. Attendees say the company also claims it was profitable on an adjusted basis. It is preparing an initial public offering that could come as soon as next month and could value it at about two trillion dollars. The meeting took place at the company's headquarters.
Some attendees expect the cooling growth will force Anthropic to keep its valuation target in check. Jim Cramer of CNBC said the financials disappointed some investors and added to the drag on the Nasdaq. Questions are also mounting over whether fast-growing AI revenue can cover the cost of chips, data centers and ever more powerful models. Anthropic reportedly earned one dollar and seventy cents for every dollar spent on compute in the quarter.
A few people protested the planned offering outside the company's New York offices. Its rival OpenAI is not expected to go public until twenty twenty-seven and is funding itself privately.
Kyiv Under Attack
Russian missile and drone strikes on Kyiv overnight into Wednesday damaged homes and energy sites, killed at least three people and cut power to more than six hundred thousand. Ukrainian President Volodymyr Zelensky said critical infrastructure was hit. At least twenty-two people were injured. Homes and a power plant were among the places struck.
Zelensky said Russia struck Ukraine with thirty-nine missiles, including Iskander-M, KN-23, S-400, Zircon and Onyx missiles. Attacks over the past day killed at least ten people and injured ninety-one. Ballistic missiles hit Kyiv for a second straight night. He said the strikes hit infrastructure covered by a ceasefire announced by the American president, and called it ostentatious disrespect.
Ukraine also says SpaceX restricted Starlink internet access that its forces use to fly drones in Russian-occupied areas, without warning. A Zelensky adviser said it cannot be a coincidence. Elon Musk wrote that any limits on speed or usage are decided by the US military and ultimately the president. Ukraine says access has improved but speed limits remain, still disrupting missions. Separately, Ukraine's security service detained an eighteen-year-old in Kyiv, suspected of working for Russia's FSB, over an attempt to activate one hundred forty-eight Starlink terminals for Russia.
Zelensky also said Kyiv received no advance warning from partners before the attacks. Presidential adviser Dmytro Lytvyn said Ukraine did not get a warning from allies in the usual way. President Donald Trump said Washington continues to share intelligence with Ukraine.
Around the Topics
Here is what else happened.
Federal agents from Homeland Security Investigations searched Democratic Representative Ilhan Omar's Washington home on Monday as part of an investigation into her immigration history. Authorities then seized her phone and issued more than a dozen grand jury subpoenas, including to some relatives. Omar called Vice President Vance delusional after he said the Justice Department is investigating her for possible immigration fraud. The search came three weeks before Election Day, and experts said it appeared to flout longstanding norms meant to keep prosecutors out of elections.
Pennsylvania's measles outbreak has reached one thousand two hundred twenty-two cases, and a coroner has confirmed a sixth death. The outbreak began in April and mostly involves unvaccinated people. It is the first in the United States to top one thousand cases since nineteen ninety-one. The CDC says it is sending a disease detective to Pennsylvania later this week at the state's request. New York State declared a State Disaster Emergency over measles, and more than four thousand cases have been confirmed nationwide.
Remnants of Tropical Storm Rachel flooded parts of the Las Vegas Strip, overwhelming storm channels and forcing road closures near major hotels. Earlier, large waves battered Southern California's coast, leaving about a dozen homes red-tagged in Long Beach, where a boardwalk was destroyed. Homes in Dana Point were at risk of collapse as high surf eroded the Orange County coast. The National Weather Service issued flood watches across the Southwest, and officials warned the flash-flood risk lingers.
A new annual review of sixteen planetary vital signs finds seven at their most extreme levels ever recorded. The State of the Climate report, in its seventh edition, was published in BioScience. It includes greenhouse gas levels and ocean heat content, and concludes Earth systems are rapidly destabilizing, some at an accelerating rate. Researchers say climate change has pushed the planet deeper into uncharted territory. The authors still see hope for solutions despite record heat and historic storms.
The Milwaukee Brewers beat the Los Angeles Dodgers six to two on Wednesday night and lead the National League Championship Series three games to none. Jake Bauers and Garrett Mitchell hit back-to-back homers off Blake Snell in the seventh inning to retake the lead. Slumping Shohei Ohtani batted sixth for the two-time defending champions. The Brewers are one win from their first World Series appearance in forty-four years. Dodgers right-hander Tyler Glasnow starts Game 4 to avoid elimination.
