Overnight Apple's John Ternus took over as CEO from Tim Cook as SB Energy — the OpenAI- and Nvidia-backed AI power buildout firm — filed to go public despite $3.2 billion in first-half losses and zero operating data centers, while the ten-year Treasury yield climbed to its highest since January 2025 on renewed Hormuz jitters and Qatar moved to broker an end to the Iran-US standoff; watch today for how markets digest AI infrastructure's staggering burn rate, the robotaxi expansion race ahead of Tesla's Cybercab event, and the last missing Grand Canyon hiker.
Army Secretary Dan Driscoll is stepping down after 18 months on the job, the White House confirmed — the latest in a string of military leadership shakeups. His exit follows reported friction with Defense Secretary Pete Hegseth and comes days after his predecessor at the Pentagon's civilian helm departed under similar strain.
A border patrol technical search team is deploying into the Grand Canyon as authorities race to find the last person still missing after Saturday's flash flood, with more rain forecast to threaten further debris flows. Two hikers — John Giusti, 46, and Brent Rosenkranz, 42 — have been confirmed dead, and pilot Timothy Smith, 53, who had been camping with them at the canyon floor, remains unaccounted for.
Britain's summer of successive heatwaves was its hottest on record, the Met Office confirmed, with a mean temperature of 16.5°C beating last year's record by a wide margin — the top five hottest UK summers have all happened since 2003. Meteorologists say human-caused climate change made a summer this hot 130 times more likely.
The Society of Professional Journalists is rewriting its century-old code of ethics for the first time in 12 years to address AI-generated content, misinformation, and a shifting media landscape. Committee chair Dan Axelrod calls the update urgent: "This is the way to protect democracy."
A woman wielding two knives killed Bank of America employee Erin Piacenti and wounded a 68-year-old man in an "unprovoked" attack along Seventh Avenue in Midtown Manhattan, NYPD Commissioner Jessica Tisch said. Police shot the suspect, who died at the hospital along with Piacenti; the male victim is in stable condition.
Qatar says it is actively working to broker an end to the Iran-US confrontation and reopen the Strait of Hormuz to normal shipping traffic.
Trump claimed on Truth Social that the US Navy had cleared all mines from the Strait of Hormuz's shipping lane, supposedly letting tankers move freely again with Air Force protection — but the columnist argues the on-the-ground reality of stranded vessels and ongoing risk doesn't match the White House's telling.
Ukrainian children began their fifth wartime school year in Kyiv's Obolon district Tuesday, with a festive first-day ceremony interrupted mid-celebration by air raid sirens as explosions sounded in the distance. Russian attacks have destroyed roughly 1 million textbooks nationwide, and officials are bracing for what could be one of the war's hardest winters.
John Ternus, Apple's former hardware chief, officially became CEO on September 1st, succeeding Tim Cook, with Johny Srouji stepping up as chief hardware officer. The transition lands just ahead of Apple's September 9th iPhone event, where the new leadership's direction on AI is expected to face its first real test.
SB Energy filed for an IPO despite generating zero revenue from its data center business and posting roughly $3.2 billion in net losses in the first half of 2026, driven by "substantial investments" in its buildout. The filing flags that the company is "substantially dependent" on OpenAI as both tenant and equity investor, and comes weeks after Nvidia pledged $105 billion in financing for an SB Energy-built OpenAI data center in Ohio.
Waymo began offering driverless rides in Denver, Tampa, and San Diego, while Amazon's Zoox said it will start testing in Houston and San Diego with safety drivers aboard — bringing Zoox to 12 US markets. The expansions land days ahead of a Tesla event expected to detail its Cybercab and Robotaxi service, with Goldman Sachs projecting the US robotaxi market to grow from about $3 billion next year to $48 billion by 2035.
The 10-year Treasury yield touched its highest level since January 2025 as renewed Middle East tensions pushed oil prices up and reignited inflation fears among traders. The 2-year yield, more sensitive to near-term Fed policy, also climbed as markets weighed the geopolitical risk premium building into borrowing costs.
Nvidia's DLSS 5 launches this week on RTX 50-series GPUs and GeForce Now, with NBA 2K27 as the only supported title at launch. Nvidia is billing it as its biggest graphics leap since real-time ray tracing in 2018, though critics have likened the AI-driven upscaling to "motion smoothing for video games, but worse."
For the first time in over 30 years, NASA has no firm plans for new Mars landers or rovers, pivoting instead to aerial drones with the SkyFall mission — a fleet of three helicopters targeting a late-2028 launch. SkyFall will ride alongside the $2.1 billion Space Reactor-1 "Freedom" mission, which repurposes the canceled Gateway lunar station's core module to demonstrate nuclear electric propulsion in deep space.
