AI euphoria and geopolitical chaos are trading at the same altitude right now, and the market is running both trades simultaneously. The dominant cross-asset signal is a sharp split: equities at all-time highs while oil craters 3.8% on Iran peace deal optimism, yet Piper Sandler warns the Strait of Hormuz stays closed for months. Futures are pushing higher pre-open, but the bond market is not confirming the party, with 10Y notes slipping again overnight.

Yesterday's US session delivered a fractured rally. The S&P 500 closed at 7,519, up 0.61%, and the Nasdaq surged 1.19% to 26,656, both printing all-time highs. The Russell 2000 led the tape, up 1.79% to 2,920, as small-caps caught a rotation bid. The Dow lagged, off 0.23% at 50,461, weighed by energy names. WTI crude collapsed 3.82% to $90.30, gold slipped 0.45% to $4,480, and the 10Y yield fell 6.5 basis points to 4.493% as the Iran-deal narrative pulled a safe-haven bid out of Treasuries and dumped it back into risk.

The causal chain runs through the Strait of Hormuz. U.S. CENTCOM strikes on Iranian missile sites, framed as a "self-defense" action to reopen the strait, triggered a crude selloff because markets are pricing a 30-day reopening timeline. At the same time, Micron's 19.3% leap to a $1 trillion market cap on AI memory demand pulled Nasdaq leadership sharply higher, with Taiwan chip stocks adding fuel after Nvidia announced $150 billion in new spending plans. New Fed Chair Kevin Warsh, who officially took the helm this week, is facing an immediate inflation test: oil moves of this magnitude, driven by a still-unresolved geopolitical blockade, are exactly the kind of supply shock that complicates a rate path. Markets are already pricing a potential 2027 hike.

For positioning, the split tape creates real opportunity. The Nasdaq's AI-driven leg higher argues for staying long growth tech (QQQ, SOXX), but the Warsh Fed's hawkish posture means duration is a risk. Bonds never bought the rally at these levels, and TLT remains exposed if oil re-spikes. The crude crash is a two-sided trade: if Hormuz reopens, energy (XLE) stays under pressure; if Piper Sandler is right and the closure extends for months, the energy trade is back on the table with force. Small-cap strength via IWM deserves attention, as the Russell's outperformance often flags a genuine risk-on rotation rather than just mega-cap momentum.

Pre-market futures are firm: S&P futures up 0.32% to 7,561, Nasdaq futures up 0.51% to 30,227, and Dow futures up 0.46%. No major data is scheduled today, making the Iran negotiation headline the single biggest swing factor. A credible Hormuz reopening announcement would hammer XLE further and compress the inflationary premium in rates. A breakdown in Doha talks reverses the crude selloff instantly and reprices everything. Watch crude at the $90 level as the session's fulcrum.
