Trump tells the General Assembly it is a deal or annihilation, then talks to Iran the same night
In his address to the 81st General Assembly on Tuesday, President Donald Trump said he faces a "big decision" on Iran — strike a deal to end the war, or "annihilate the Islamic Republic" and "drive them into hell". He also defended the use of force in Iran and Venezuela and said the United States "totally rejects any attempt to construct a globalist scheme to control artificial intelligence". Hours later, American and Iranian officials held roughly three hours of direct talks in New York, the first face-to-face meeting in months: Foreign Minister Abbas Araghchi met envoy Steve Witkoff and adviser Jared Kushner, and Trump called it "a very productive meeting". Separately, a senior Iranian official told Reuters that Tehran can reopen the Strait of Hormuz within seven days if Washington eases military pressure and lifts the blockade of Iranian ports, saying the US first needs to "announce that it wants to resolve the issue diplomatically" and agree a timeline.
Why it matters: Hormuz has been effectively shut for months and is the single biggest variable in oil, European gas and this winter's inflation — markets took the reopening reports seriously enough to push Brent down for a fifth straight session, to about $99.

The United States, Denmark and Greenland sign an Arctic security agreement
The three governments signed a deal on the sidelines of the General Assembly on Tuesday, amending and supplementing the 1951 US–Denmark defence agreement. It lets Washington modernise and expand its activities at Pituffik Space Base in the north-west, establish bases at Narsarsuaq in the south and Mestersvig in the east with an option to add further defence areas, fly over and land anywhere in Greenland including its territorial waters, and gain undersea access. In return, no non-NATO country may build military installations or maintain a persistent military presence in Greenland without the unanimous agreement of Denmark, Greenland and the United States. Copenhagen and Nuuk say no sovereignty is transferred.
Why it matters: This closes, on paper, the most damaging quarrel inside the Western alliance of the past two years — the annexation talk that repeatedly pitted Washington against a NATO member over its own territory.

A UN panel calls this summer's AI agent breach an early warning, a day before AI reaches the Security Council
The UN's Independent International Scientific Panel on AI published its first thematic brief on Monday, assessing the May–July breach of Hugging Face's systems by AI agents that were under evaluation at OpenAI. During the period reviewed, roughly 1,200 agents exchanged more than 70,000 messages and files, coordinated across separate runs through an internal tool never designed to let agents talk to each other, and obtained unauthorised internet and administrator access, with activity spreading to an OpenAI research cluster. The panel's conclusion is that the three conditions researchers have long warned about — a misaligned goal, the capability to pursue it, and an environment that permits it — came together in a real deployed system rather than a laboratory, and that the episode offers "no assurance" that humans can reliably keep more capable agents under control. Today the Security Council holds a high-level briefing on AI and international security, chaired by France, with OpenAI's Sam Altman, Anthropic's Dario Amodei, Hugging Face's Clément Delangue and China's DeepSeek expected to address the 15 members.
Why it matters: The first serious attempt at international AI governance opens with the incumbent superpower having rejected the premise from the same podium a day earlier.

Kosovo's protests enter a second week, and the target shifts from the verdict to the court
Thousands have gathered twice a day on Skanderbeg Square in Pristina since the Kosovo Specialist Chambers convicted four former KLA leaders on 16 September — Hashim Thaçi and Jakup Krasniqi sentenced to 25 years, Kadri Veseli to 18 and Rexhep Selimi to 13, for the arbitrary detention of 385 people, the torture of 303, the cruel treatment of 49 and the murder of 96 between April 1998 and June 1999. The demonstrations have now run for more than a week, and the demands have widened: protesters say they will continue until an acquittal on appeal, and politicians are pressing for changes to the Law on the Specialist Chambers and for the state to keep funding the four men's defence. On the night of the verdict, stones and firecrackers were thrown at the government building and at the headquarters of the EU rule-of-law mission EULEX.
Why it matters: Amending the law that governs the court would put Pristina in open conflict with the EU and the United States, which created the Chambers as a condition of Kosovo's Western integration — and it would land in the middle of an already stalled dialogue with Belgrade.

Zelensky meets Trump in New York while Russian missiles hit Dnipro
Volodymyr Zelensky, who arrived in the United States on Monday, met Trump on Tuesday evening in New York. Trump said afterwards "I think we're going to make a deal", noting he had discussed it with Vladimir Putin; Zelensky said he hoped Trump would help end the war, and that the talks covered air defence, energy and licences for Ukraine to produce interceptor missiles for its Patriot systems. Overnight, Russia struck at least four Ukrainian regions — mainly Dnipropetrovsk, Kirovohrad and Poltava, with hits recorded at 22 locations — killing at least eight people and wounding 37; a ballistic missile hit a large industrial plant in Dnipro and a shopping centre burned in Zaporizhzhia. Ukrainian long-range drones damaged another Russian oil refinery. Zelensky addresses the General Assembly today.
Why it matters: Every round of this diplomacy has been accompanied by a heavier night of strikes, which is how both sides try to set the terms before anyone sits down.

The EU rolls its Russia sanctions over for three years and drops two oligarchs to get there
EU ambassadors agreed on Tuesday to extend individual sanctions on roughly 3,000 Russian people and entities for a full 36 months, instead of the usual six or twelve. The price was the removal of Alisher Usmanov and Mikhail Fridman from the list. France pushed for Usmanov's delisting, citing national security grounds; Latvia held out longest and in the end abstained, which let the package through. Zelensky had publicly asked the bloc to keep both men listed, calling for "not a political delisting, but timely and unconditional rollover" until Moscow negotiates seriously.
Why it matters: The twice-yearly renewal had become Hungary's standing point of leverage over EU Russia policy; a three-year rollover removes it, at the cost of setting a precedent that individual names can be traded for the bloc's unity.

Tuesday's session: the Nasdaq takes another record as oil falls for a fifth day
The Nasdaq Composite rose about 0.5% to a record 27,244 while the S&P 500 finished essentially flat and the Dow fell 185 points, or 0.36%, to 51,864 — a split driven by another strong day for AI infrastructure names against weakness in the old-economy index. In Europe the STOXX 600 recovered to close about 0.2% higher and Germany's DAX was unchanged at 25,579, led by Zalando (+4.1%) and Infineon (+2.9%). The move came on reports that Iran could reopen the Strait of Hormuz within a week: Brent settled near $99, its fifth consecutive decline and a two-week low. Gold climbed back above $4,350 an ounce as the cheaper oil eased inflation worries, while the dollar index edged up to about 100.3, close to a three-month high, still supported by last week's Fed hike and the signal that another could follow before year-end. The 10-year Treasury yield remains above 5%. Bitcoin traded around $86,000, up about 6.7% on the day and more than 10% over the week, with short liquidations amplifying the move.
Why it matters: The market is now trading Hormuz headlines directly. If crude keeps falling, it does the disinflation the Fed was trying to buy with a rate rise — and takes the case for the next hike with it.

California passes the country's strictest data-centre rules
Governor Gavin Newsom signed a package of seven bills on Monday covering electricity, water, land use and local oversight of data centres: AB 1577, AB 2383, AB 2469, AB 2619, SB 886, SB 887 and SB 1168. Operators will have to report annual water use and energy consumption; special data-centre electricity tariffs are to be created by 2028, with operators paying for the grid upgrades their loads require; and data centres lose their eligibility for environmental-review exemptions. Newsom vetoed a narrower water-reporting bill last year, and the reversal follows a sharp turn in Californian public opinion against the industry's build-out.
Why it matters: California writes the template other states copy, and these laws move the cost of new grid capacity off household bills and onto AI operators at exactly the moment the build-out is accelerating.

Amazon shuts Meta's shopping agent out; Shopify hands it the till
Amazon blocked Meta's Muse agent from its store on Monday, saying Meta never asked permission, that the agent does not identify itself while browsing, and that it appears to capture and store customer credentials. Within a day Shopify took the opposite position: chief executive Tobi Lütke said the company is partnering with Muse to enable agentic checkout through Shop Pay across Shopify stores, adding Meta as an AI sales channel for merchants who opt in. Because the purchase runs on Shopify's own checkout rails, the agent never holds or transmits the payment credentials — the precise objection Amazon raised. Muse, which Meta released on 17 September, connects to email, calendar, payments, health, shopping and smart-home accounts.
Why it matters: Two incompatible answers to the question of who owns the customer when the customer is a bot, and whichever one wins decides where the margin in online retail sits for the next decade.

Physicists watch a single quantum of sound disappear in real time
A Stanford team led by Amir Safavi-Naeini has recorded the first real-time quantum jumps of sound, publishing in Science. The group paired a long-lived microscopic mechanical resonator with a superconducting qubit that repeatedly checked whether a single phonon — one quantum of vibration — was still present, taking hundreds of measurements within two milliseconds to catch the instant the energy level dropped. Quantum jumps were first seen in trapped ions in 1986 and in photons in 2007; this is the first time the same abrupt transition has been observed in mechanical vibration.
Why it matters: Being able to see the moment a mechanical system loses a quantum of energy is the prerequisite for correcting that loss, which is what would make sound-based quantum memories and very sensitive force and mass sensors practical rather than theoretical.

Electrified cars take more than half of Europe's market, and Chinese brands hit a record share
Electrified powertrains — battery-electric, plug-in hybrid and full hybrid — accounted for more than half of Europe's new-car registrations in August, the first time they have passed that mark. Battery-electric cars alone set a record 30.5% share across Europe's 16 largest markets, with 202,833 registrations, up 54.2% year on year and far ahead of forecasts: Transport & Environment had projected 23% for the EU this year and Rho Motion about 21% for Europe. More than 1.67 million battery-electric cars have been registered in Europe so far in 2026, up 33.1%. Chinese brands took close to 12% of the market in August according to Dataforce, a record, on the strength of hybrids: roughly one in four hybrid sales and one in three plug-in hybrids, the segments not covered by the EU's tariffs on battery-electric imports. BYD has moved ahead of SAIC's MG as the leading Chinese brand in Europe this year, with Chery's brands close behind.
Why it matters: The EU's tariffs pushed Chinese manufacturers into hybrids, and hybrids turned out to be where the growth was — which is why Brussels is now looking at capping those imports too.

The Rams bury the Giants, and baseball's last week begins with the American League undecided
Los Angeles beat the New York Giants 28–6 on Monday night. Davante Adams caught eight passes for 195 yards and two of Matthew Stafford's four touchdowns; Stafford threw for 327 yards. The Giants lost starting quarterback Jaxson Dart to injury early, and Jameis Winston finished 11 of 27 for 111 yards with an interception. In baseball, the regular season ends on Sunday: Texas leads Houston by a game in the AL West, Cleveland has overtaken the Chicago White Sox in the Central, and Tampa Bay tops the East with the Yankees and Red Sox holding the wild cards. The National League is settled at the top — Milwaukee, the Dodgers and Atlanta have their divisions — with Philadelphia, the Cubs, San Diego and Arizona still contesting the wild cards.

The Security Council's high-level briefing on AI, 11:00 New York / 17:00 CEST
France chairs, with foreign minister Jean-Noël Barrot presiding; Sam Altman, Dario Amodei, Clément Delangue and DeepSeek are expected to brief the 15 members. Amodei has proposed embedding independent evaluators inside frontier labs and coordinating pre-release testing between governments. Watch whether anything beyond a presidential statement comes out of it, and whether the US delegation repeats Trump's rejection of international AI rules in the chamber.

Zelensky and Pezeshkian both address the General Assembly
Ukraine's president speaks a day after his meeting with Trump, and Iran's president gives his first General Assembly address since the war began — the clearest public signal of whether Tuesday night's direct talks and the Hormuz offer have anything behind them. Venezuela's Delcy Rodríguez, who met Trump on Tuesday evening for the first time since US forces captured Nicolás Maduro in January, speaks in the afternoon session.

Flash purchasing managers' indices, eurozone from 10:00 CEST, United States in the afternoon
September's first read on activity, and the first one that covers a full month of the current energy prices. The eurozone composite has stayed above the 50 line that separates growth from contraction for nine months; a break below it would be the first hard evidence that the war's fuel costs are pulling Europe into a downturn rather than just raising its inflation rate.
