World leaders descended on New York this week for the annual United Nations General Assembly, where the agenda spans the U.S.-Iran war and Russia’s invasion of Ukraine to the fragile ceasefire in Gaza and the risks posed by artificial intelligence.

Nearly 130 heads of state and government started taking the podium on Tuesday, including U.S. President Donald Trump, French President Emmanuel Macron, Ukrainian President Volodymyr Zelenskyy, and European Commission President Ursula von der Leyen. Brazil’s Luiz Inácio Lula da Silva, Jordan’s King Abdullah II and Qatar’s Emir Sheikh Tamim bin Hamad Al Thani are also attending.

Motorcades, road closures and security details for visiting leaders have choked midtown Manhattan. Inside UN headquarters, delegates face a week of back-to-back speeches and sideline meetings that come at a crucial time for a world order already under strain.

Chinese leader Xi Jinping will skip the assembly but head to Washington for a high-level summit with Trump on Wednesday. Leaders from India and Russia are also staying away.

Trump on Tuesday told world leaders at the assembly that he faces a “big decision”: make a deal with Iran or “annihilate” the Islamic Republic. He later told reporters that U.S. officials held a “very good” three-hour meeting with Iranian envoys on the sidelines, reviving fragile hopes for a diplomatic off-ramp to the seven-month war.

South Korean President Lee Jae Myung set out a three-part plan for “peaceful coexistence” with North Korea. It calls on Pyongyang to “first halt the advancement” of its nuclear program before reducing it.

Brazil’s Lula spoke first, as his country traditionally does. “Brazilian democracy belongs to Brazilians,” Lula said. “Brazil is nobody’s backyard.” He said the UN “is failing in one of its highest missions: to save humanity from the scourge of war.”

Trump also signed a security agreement with Denmark and Greenland that expands U.S. military access in the semi-autonomous Danish territory of Greenland.

Trump then met Ukrainian President Volodymyr Zelenskyy for about 40 minutes. He pressed for a Russia-Ukraine energy truce and backed a ban on U.S. diesel exports as fuel prices hit records before the midterms.

French President Emmanuel Macron gave his own UN address. “There can be no peace without justice,” he said. After meeting Trump, he pledged to push for a moratorium on strikes on Ukraine’s energy grid.

Turkish President Recep Tayyip Erdogan called Gaza “the most inhumane, most shameful concentration camp of our time,” prompting Israel’s delegation to walk out. Mahmoud Abbas, President of the Palestinian Authority, will address the assembly by video after being denied a U.S. visa.

Oil declined on Wednesday as optimism grew that supply disruptions could ease after U.S.-Iran talks, lifting hopes for a diplomatic resolution to the Middle East conflict.

Futures on the international benchmark Brent crude for November delivery fell 0.71% to $98.55 a barrel as of 3:04 a.m. ET. U.S. West Texas Intermediate futures for November slipped 1.26% to $89.36 per barrel.

President Donald Trump said Tuesday that U.S. officials had a “very good meeting” with Iran’s delegation, which lasted about three hours. Earlier, during his address to the U.N., Trump said he faced a “big decision” over whether to make a deal with Tehran or “annihilate” the country.

Reuters reported Tuesday that Iran could reopen the Strait of Hormuz within a week if the U.S. agrees to reduce military pressure and lift its blockade of Iranian ports.

“Pakistan’s mediation efforts with Tehran could also reduce the risk of a broader escalation,” said Paolo Broccardo, chief executive officer at private digital bank BankPro.

He said oil prices were also unlikely to surge sharply in the near term.

“Over the past five consecutive sessions, the price has fallen by almost 12%, retreating once again from the ‘intervention zone’ above $100, where we have repeatedly seen intensified peace-building efforts from both sides,” Broccardo said.

Hello, this is Leonie Kidd coming to you from London. Welcome to another edition of CNBC’s Daily Open.

President Donald Trump’s passion for renaming places is now extending to renaming technological developments.

His latest effort is to rebrand AI as ‘Super Intelligence.’

However, it will take more than a facelift for the most transformative technology in a generation to meet the expectations for a global safety approach, especially ahead of the meeting with Chinese President Xi Jinping, who will be welcomed to Washington D.C., later on Wednesday.

What you need to know today

“The use of the word artificial makes intelligence fake… It is not fake. It’s actually amazing.”

The words of U.S. President Donald Trump as he used his keynote speech at the United Nations General Assembly to call for the renaming of AI as “Super Intelligence.”

His support for allowing AI (or Super Intelligence) to develop at a winning pace comes as his global peers look to reach an agreement on safety rules around the powerful technology.

Later on Wednesday, Trump will greet China’s Xi Jinping in an arrival ceremony ahead of Thursday’s state visit, where AI has become one of the key talking points between the two superpowers.

Speed versus safety

The CEO of OpenAI Sam Altman and Anthropic boss Dario Amodei are expected to address the United Nations Security Council later on Wednesday. They are set to be joined by Hugging Face CEO Clément Delangue to debate AI safety and regulation.

The appearance follows calls to slow the breakneck pace of the model frontier — warnings Trump has called a “hoax” and “scam.”

Frontier FOMO

Investors are taking an optimistic view, with a rally in technology stocks on Tuesday leading the Nasdaq to another fresh high. The tech-heavy index hit a new all-time intraday peak and achieved a record close.

Futures are flat in early trading on Wednesday amid a broadly positive handover from Asia.

Oil oscillations

Crude prices are lower on Wednesday following news that U.S. officials had a “very good meeting” with the Iranian delegation on the sidelines of the UN meeting.

President Trump said the discussion with officials lasted about three hours. Earlier in his address to the U.N., he said he has a “big decision” over whether to reach a deal with Tehran or “annihilate” the country.

According to regional media reports, Iran has been communicating its conditions for ending the seven-month war with the U.S. through a Qatari mediator.

Anthropic and OpenAI roll out cheaper models in first release since call for slowdown

Anthropic and OpenAI on Tuesday each announced new, less costly artificial intelligence models as both frontier labs continue to face stiff competition from cheaper, open-weight competitors.

OpenAI introduced additional tiers to its GPT-6 family, with GPT-6 Sol and GPT-6 Luna, slashing the API prices by 50% compared with GPT-5.6 promotional pricing.

Sol, which is a tier below Astra, is meant for more complex workloads like coding, while the company’s Luna offering is geared toward “high-volume tasks” such as extracting information or summarizing documents, the company wrote.

Anthropic unveiled Claude Opus 5.5 on Tuesday, its latest release in the new Claude 5.5 model family.
