Summary

- The U.S. Senate advances a resolution that will halt military action in Iran. - Long term Treasury yield rises to highest since 2007. - The S&P 500 notches its third straight loss on the back of rising rates. - Google rolls out Gemini 3.5 Flash. - Anthropic hires OpenAI co-founder Andrej Karpathy. Hello, this is Hui Jie writing to you from Singapore. Welcome to another edition of CNBC's Daily Open. From a Senate rebuke on Iran war to surging Treasury yields and accelerating inflation, U.S. President Donald Trump is facing several headwinds ahead of the midterms. Meanwhile, the tech sector continues to make headlines with Google unveiling new AI models, SpaceX tapping Goldman Sachs for its IPO, and Anthropic hiring OpenAI co‑founder Andrej Karpathy. What you need to know today U.S. President Donald Trump has said that he is holding off on striking Iran at the request of Gulf countries, but even at home his military operation against Tehran has come under sharp scrutiny with the Senate advancing a resolution to halt action against the Mideastern country. While the resolution stands little chance of becoming law due to Trump's veto power, the vote does show increasing headwinds to the war with Iran, especially as gas prices continue to soar ahead of the summer driving season and the midterm elections. Trump came under more scrutiny, as Vice President JD Vance was asked at the White House press briefing about the heavy stock trading on display in the president's latest financial disclosures, which revealed transactions totaling hundreds of millions of dollars over just three months. "He's not making these stock trades himself," the vice president said, while accusing the reporter of suggesting otherwise. Meanwhile, yields on U.S. 30-year Treasurys climbed to their highest level since July 2007, hitting 5.197% Tuesday amid worries over rising inflation. Treasurys have seen a sell-off following reports last week that pointed to increasing inflationary pressure, as the Iran war pushes energy prices higher. Rising yields have pressured stocks, with the S&P 500 notching its third straight losing session and the Nasdaq Composite and Dow Jones Industrial Average also suffering losses overnight. Over in the tech world, Google announced Gemini 3.5 Flash, which CEO Sundar Pichai described as a lighter-weight addition to the company's AI suite that offers cutting-edge capabilities at half, or in some cases close to one-third, the price of comparable frontier models. Competition for top talent in AI continues to intensify, with former OpenAI co-founder and Tesla AI leader, Andrej Karpathy, moving to Anthropic. Anthropic said Karpathy starts this week and will be building a team focused on using Claude to accelerate pre-training research that helps the company's models acquire their core knowledge and capabilities. Moving from AI to rockets, SpaceX has picked Goldman Sachs to lead what's likely to be a record IPO, sources told CNBC. Elon Musk's reusable rocket company, most recently valued at $1.25 trillion by Musk, could make its prospectus public as soon as Wednesday. — Lim Hui Jie And finally... Putin in Beijing: 3 things Russia needs from China As Russian President Vladimir Putin travels to China, Moscow's leader will be keen not only to bolster ties with Beijing but also to extract key wins in areas of trade and energy. Putin's two-day trip to Beijing comes hot on the heels of his U.S. counterpart Donald Trump's state visit, which saw the White House boast diplomatic and trade wins. The Russian president now heads to Beijing with the hope of reaffirming and reinforcing already close ties with China. — Holly Ellyatt

Perspectives

Iranian Official

The Iranian government views the US Senate's advancement of a resolution to halt military action as a clear admission of Washington's illegitimate aggression and failed attempts to undermine Iran's sovereignty. This domestic pushback highlights growing resistance to foreign intervention, even as Tehran stands firm against external threats coordinated with Gulf allies. Iran continues to defend its territorial integrity amid such provocations.

Israeli

The U.S. Senate's push to block military action against Iran directly weakens efforts to counter the regime's existential threats to Israel, including its nuclear ambitions and vast proxy network of Hezbollah, Hamas, and the Houthis that have launched sustained attacks on Israeli territory. Despite the resolution's limited prospects of overriding a veto, it highlights eroding U.S. resolve at a time when decisive force remains essential to degrade Iran's offensive capabilities and protect Israel's survival. Defensive operations against Tehran are not optional but a necessity to prevent further escalation from this axis of aggression.

Neutral

The U.S. Senate has advanced a resolution to halt military action against Iran. Long-term Treasury yields reached their highest level since 2007, coinciding with a third consecutive decline in the S&P 500. Google released the Gemini 3.5 Flash model, and Anthropic hired OpenAI co-founder Andrej Karpathy.

Western

The U.S. Senate's advancement of a resolution to curb military action against Iran highlights domestic political constraints, even as the Trump administration prioritizes strategic objectives to neutralize Tehran's regional threats through precise, targeted operations requested by Gulf partners. Rising Treasury yields to 2007 highs and the S&P 500's third consecutive decline underscore market pressures amid these efforts to counter Iranian aggression ahead of midterms. In parallel, tech advancements continue with Google's Gemini 3.5 Flash rollout and Anthropic's strategic hire of OpenAI co-founder Andrej Karpathy to bolster AI capabilities.

Pro-Peace

The U.S. Senate's advance of a resolution to halt military strikes on Iran offers a vital check against escalation that risks severe civilian casualties and deepening humanitarian suffering across the region. With Gulf nations urging restraint to avoid broader fallout, the move highlights the urgent priority of diplomatic channels over costly military action amid rising economic strains on families. Prioritizing de-escalation could spare countless lives while addressing shared security concerns without further destabilization.

Global South

The US Senate's resolution against strikes on Iran exposes Washington's persistent neo-colonial interference in sovereign Middle Eastern affairs, driven by Gulf pressures yet undermined by presidential veto powers that reveal deep institutional paralysis. Surging Treasury yields and equity losses further signal American financial fragility, poised to transmit inflation and debt distress across the Global South through dollar dominance. Concurrently, US tech giants' AI rollouts and executive poaching entrench Silicon Valley monopolies, sidelining independent development in non-aligned nations.

Reports indicate that a US-Iran ceasefire has broken down amid renewed fighting, with the potential impact of mediation efforts by Pakistan, Qatar, and Oman remaining unclear. Earlier diplomatic steps included a June memorandum of understanding between the parties for further negotiations and talks hosted in Geneva in February.

The summary also references Europe’s historical role in diplomacy, including the 1814-15 Congress of Vienna.

Donald Trump stated in a Fox News interview that his representatives had spoken with Iranian officials an hour earlier and that those officials wanted to make a deal to end the conflict, though he noted they had broken prior agreements and expressed uncertainty about whether one would be reached.

He added that people do not want to die and that Iran would need to proceed carefully to avoid further losses. The remarks come amid an ongoing US-Iran conflict that has involved casualties and shipping disruptions in the Strait of Hormuz, with some social media users criticizing the repetition of similar statements.

Why the Iran-US ceasefire is falling apart Iran and the US have resumed fighting because they don’t see each other as ‘reliable negotiating partners’, says analyst Ali Vaez. Neither Iran nor the United States seems able to deliver a “knockout blow at an acceptable price” to the other side, and both know “they have no choice other than engaging in diplomacy”, but they’re not ready to make uncomfortable concessions, argues Ali Vaez, director of the Iran Project at International Crisis Group.

Vaez tells host Steve Clemons that Tehran and Washington are trying to “enforce their own interpretation” of the ceasefire agreement they signed last month. President Trump has become “frustrated” with diplomacy because he’s not seeing “the kind of quick results that he likes to see”, Vaez says.
