• Good morning, it's Thursday, October 1st. We're seeing a tense setup for the U.S. open as the bond market remains in the driver's seat. S&P 500 futures are slightly positive, up about 0.12%, and Nasdaq futures are showing more strength, up 0.40%. However, Dow futures are pointing lower by 0.43%. The big story overnight is the 10-year Treasury yield, which is holding near 5.33%, a 24-year high that's pressuring equities. Overseas, Asian markets closed sharply higher, with the Nikkei surging 3.3%, while European markets are broadly in the red. With me are our Markets and World analysts.
• Looking at the calendar for today, we have a couple of key economic data points investors will be watching closely. At 8:30 AM Eastern, we get the latest initial jobless claims, followed by the ISM Manufacturing PMI at 10 AM. On the earnings front, Accenture and McCormick reported before the bell. We'll be watching Nike's results after the close. And it's a very busy day for Fed-speak, with four different governors scheduled to make public remarks, starting with Governor Waller at 10 AM. We'll be listening for any new signals on monetary policy.
• That's right, the pressure from the bond market is undeniable. The selloff in government bonds has intensified, pushing the 10-year U.S. Treasury yield to a high of 5.342%, a level we haven't seen since 2002. The 30-year yield is also at a multi-decade high, touching 5.683%. The core drivers here are persistent inflation fears and concerns over the scale of government debt issuance. This rapid rise in borrowing costs creates a significant valuation headwind for equities, particularly for growth and tech stocks, as future earnings are discounted at a higher rate.
• But in the face of that macro pressure, we have a stunning micro story from the semiconductor space. Micron Technology reported a blowout quarter, with revenue surging 380% year-over-year to $54 billion, crushing expectations. The memory-chip maker also delivered a very strong forecast, citing incredible demand from the AI sector. They've already secured $32 billion in customer commitments for their advanced chips. CEO Sanjay Mehrotra added that he expects memory supply to be much tighter in the coming years, signaling continued pricing power.
• And the AI arms race continues to escalate. Google's parent company, Alphabet, has just unveiled its new flagship AI model, Gemini 4 Argon. The company is making bold claims, stating that the model matches or even exceeds the performance of top rivals from Anthropic and OpenAI, especially in complex areas like coding and cybersecurity. In a sign of its power, the model is being released first to select cybersecurity partners. One early test reportedly identified a critical vulnerability in healthcare software that previous AI models had completely missed.
• It's not all good news in the tech supply chain, however. We're seeing a real head-scratcher with Jabil this morning. The manufacturing solutions provider reported strong fourth-quarter results, with revenue of $10.6 billion and a core EPS of $4.40, both beating expectations. They also projected a massive 54% increase in AI-related revenue for the next fiscal year. Despite all that, the stock is down about 10% in pre-market trading. Analysts are pointing to concerns over the company's thin operating margins as the potential reason for the selloff.
• In the healthcare space, a major legal victory for United Therapeutics has its shares soaring. The stock jumped roughly 13% in pre-market action after a federal court ruled that a rival lung drug from Liquidia directly infringes on its patent for the blockbuster drug Tyvaso. This is a significant win, potentially protecting a major revenue stream from competition for years. The company says it will now ask the FDA to withdraw the rival drug's approval and will also seek financial damages for past infringement.
• Turning to geopolitics, there are signs of movement in the seven-month conflict in the Gulf. Reports indicate Iran has received a formal U.S. response to its latest ceasefire proposal. The core of the Iranian plan is a trade: the U.S. would lift its blockade of Iranian ports in exchange for Iran reopening the critical Strait of Hormuz to shipping. While President Trump had publicly dismissed the initial plan, officials are stressing that indirect talks are still ongoing, with one White House source stating a deal remains possible.
• And let's circle back to that Micron story, because the positive sentiment is lifting the entire semiconductor sector. This is providing a crucial buffer against those broader market pressures from rising yields. Following Micron's report, other major chip stocks are rallying in the pre-market. Lam Research and Applied Materials are both up about 1.8%, while the AI giants Nvidia and Advanced Micro Devices are each trading higher by about 1%. It's a clear sign that investors still have a strong appetite for the AI growth story.
• That appetite for AI is fueling a battle of titans. Alphabet's Gemini 4 Argon release is a direct challenge not just to OpenAI and Anthropic, but to a whole ecosystem of startups and established players. The focus on specialized skills like cybersecurity shows the next frontier isn't just general intelligence, but verifiable, mission-critical performance. This raises the stakes for enterprise adoption and puts pressure on all players to demonstrate not just capability, but trustworthiness and a clear return on investment, moving the AI narrative from potential to proven utility.
• And those geopolitical talks in the Gulf are having a direct impact on energy markets this morning. Crude prices are ticking lower on hopes that a potential deal could de-escalate tensions and ensure supply through the Strait of Hormuz. WTI crude is down about 0.40% to around $90 a barrel, while Brent, the international benchmark, is off 0.70% near $97.30. While diplomacy continues, any sign of a breakdown in these indirect talks could cause an immediate spike in prices, so traders are watching every headline out of the region very closely.
• Micron Technology rallied after reporting record-breaking fourth-quarter results that significantly beat expectations. The memory chip maker closed up, ending the day at $1,065.11, a gain of over 1 percent. Revenue soared 379% year-over-year to $54.23 billion, fueled by surging demand for its memory products in AI data centers. This strong performance signals a robust outlook for the semiconductor industry as AI development continues to accelerate.
• Shares of Boeing initially rose before closing down slightly at $186.05. The aerospace giant announced it had won a major $20 billion contract to develop the U.S. Navy's next-generation F/A-XX fighter jet. This award solidifies Boeing's position as a key player in advanced military aircraft, as it also secured the contract for the Air Force's next-gen fighter in 2025. The win provides a significant long-term revenue stream for its defense division.
• Moderna sank in Wednesday's session, closing down nearly 7% at $189.84. The sharp drop was triggered by a downgrade from Citi to a 'sell' rating, with the firm citing an 'unjustifiable' valuation following the stock's massive run-up. The rally was fueled by positive results for its personalized cancer vaccine, but analysts now question if the current share price has outpaced realistic commercial prospects for the treatment.
• So, the one thing to watch today is the bond market's grip on sentiment. The primary focus will be whether this relentless rise in Treasury yields continues. With the 10-year at levels not seen in over two decades, the pressure on equity valuations is immense. Today's 8:30 AM initial jobless claims and 10 AM ISM manufacturing data will be scrutinized for any signs of economic weakness that could temper this bond selloff. And that heavy slate of Fed speakers throughout the day could introduce even more volatility as investors hunt for any shift in monetary policy rhetoric.
