4. Key Events of the Session

• Muse ignites the CPU trade

  Meta's AI agent Muse launched on September 8 and quickly topped Apple's App Store free-app chart. The market repriced server CPU demand: agent inference and orchestration workloads convert directly into CPU consumption. Jefferies was explicit that broader agent adoption benefits server CPU demand, and OpenAI was reported to be racing to build a competing agent — the contest has shifted from chatting to getting things done.
• Crude falls a fourth straight session, WTI down more than 4.5%

  October WTI settled at 95.78 dollars a barrel (-4.51%) and November Brent at 100.34 dollars (-3.40%), both two-week lows. Middle East de-escalation signals built around the UN General Assembly, with Trump saying he might meet Iran's President Pezeshkian, easing supply-disruption fears.
• The 10-year Treasury yield breaks back below 5%

  The 10-year yield fell 5bp to 4.96%, back under the psychological line; the 30-year dropped 5bp to 5.29%. The long-end-led retreat in rates took direct pressure off growth-stock valuations.
• Paramount's merger clears its last hurdle

  Paramount settled with California and 11 other states over its 110-billion-dollar acquisition of Warner Bros. Discovery, clearing the final legal obstacle to a deal that would redraw Hollywood; WBD jumped more than 10%.
• Goolsbee pushes back: supply shocks are the new normal

  The Fed delivered its first hike in three years just last week, and CME pricing puts the odds of another move next month near 50%. Chicago Fed President Goolsbee warned that supply shocks have become routine and policymakers need evidence they are fading. Bitcoin pushed above the 80,000-dollar mark for its highest since late January; Coinbase and Strategy rose more than 4%.

5. Cross-Asset: Oil and Gold Down, Crypto and Stocks Up

6. Takeaways

• The record close is, at bottom, a denominator story
  Four straight oil losses plus a 10-year yield back under 5% let duration assets breathe, and the Nasdaq printed a record. Stay clear-eyed: the Fed hiked just last week and Goolsbee is still flagging supply shocks — the "cheap oil equals easing" chain hangs entirely on crude. If oil stops falling, the logic turns brittle fast.
• Muse lit a narrative chase, not a new fundamental
  AMD's trillion-dollar milestone rests on one customer representing about 5.5% of revenue being amplified by agent demand. After a +9.95% day the risk-reward of chasing is ordinary; the real confirmation is actual server CPU order data, not an App Store chart.
• Money is picking narratives, not sweeping everything
  Storage lagged badly on the same day and SanDisk closed lower — the market bought the CPU-and-optical storyline only. In a tape like this, picking the right group matters far more than chasing the index.
• Two things to watch this week
  Whether Trump meets Iran's president at the General Assembly — that decides the next leg for oil and rates; and what comes out of the US–China leaders' summit — that decides whether tech risk appetite holds. Pricing another hike next month at roughly 50% odds is itself an open question.
