Semis Surge, Mega-Caps Slide as Soft CPI Splits the Market

The market opened to a bifurcated tape on Wednesday, and the Nasdaq-100’s composition made it one of the cleanest tells in the snapshot: semiconductor names surged while the mega-cap platforms that buy their chips sold off. The VanEck Semiconductor ETF (SMH) jumped 2.43% to $586.86 as of 12:07 ET^[1], powered by Nvidia’s +2.72% move to $223.43^[1]. Meanwhile META fell 2.87%, MSFT dropped 2.23%, and AMZN slid 1.67%^[1]. The S&P 500 (SPY) traded modestly higher at $772.13 (+0.20%) and the Dow (DIA) was nearly flat at $537.62 (+0.06%), but the QQQ’s +0.73% gain masked a sharp internal divergence between who collects AI revenue and who spends AI capex^[1].

Two catalysts drove the open: a softer-than-expected July CPI report released at 8:30 AM ET, and Nvidia’s announcement over the weekend that it had signed memorandums of understanding with six Wall Street giants — Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, and KKR — to establish financing platforms mobilizing over $500 billion in third-party capital for AI infrastructure^[2].

The CPI: energy retreats, core holds

The Bureau of Labor Statistics reported that headline CPI rose just 0.1% on a seasonally adjusted basis in July, following a 0.4% decline in June^[3]. The year-over-year all-items index eased to 3.4%, down from 3.5% in June^[3].

The detail behind the headline tells a more nuanced story:

Energy declined for a second straight month — gasoline fell 2.9% after a 9.7% drop in June — and that pulled the headline down^[3]. But the year-over-year energy index is still running at +14.7%, with gasoline up nearly 25% over the past twelve months^[3]. Core inflation, which strips out food and energy, ticked up 0.2% on the month and held at 2.5% year-over-year, down one tick from 2.6% in June^[3].

Shelter — which accounts for roughly two-thirds of the monthly increase — rose just 0.1%, its slowest pace in recent months, and owners’ equivalent rent climbed 0.3%^[3]. The deceleration in shelter is consistent with the broader disinflationary trend in core services, but at 3.2% year-over-year, shelter is still running well above the 2% Fed target.

The macro backdrop frames this print: the Fed funds rate sits at 3.63%, the 10-year Treasury yields 4.65%, and the 2s-10s yield curve is positively sloped at +0.48%^[4]. Unemployment is 4.1%^[4]. Real GDP is growing at 2.1% year-over-year^[4]. The VIX is low at 15.15, and high-yield credit spreads are tight at 2.70%^[4]. Consumer sentiment, however, sits at just 49.5 — down 18.45% year-over-year — even as it rebounded 10.49% month-over-month^[4].

The FRED analog search flags the 2006-07 period as the closest macro match — a time when the Fed had paused rate hikes, the yield curve was normalizing, and recession was not yet visible in the data but was quietly building^[4]. That does not mean a recession is imminent today, but it does mean the current configuration — disinflation without a hard landing, low unemployment, elevated but easing inflation — has a precedent, and that precedent did not resolve gently.

Nvidia’s $500 billion financing gambit

On August 10, Nvidia announced memorandums of understanding with Apollo Global Management, Blackstone, BlackRock, Brookfield Asset Management, Goldman Sachs, and KKR to establish AI compute infrastructure financing platforms that aim to mobilize over $500 billion in third-party capital^[2]. The financing would flow to hyperscalers, frontier AI labs, and enterprises building data centers and acquiring Nvidia hardware^[2].

The market’s reaction was immediate and concentrated in semis: SMH gained 2.43%, NVDA rose 2.72%, and the TipRanks headline noted pre-market strength across Micron, AMD, Intel, and Super Micro as well^[5]. The VanEck Semiconductor ETF had been in recovery mode after a deep July selloff that erased more than $1 trillion in market value across the semiconductor industry, and the Schwab Network noted the SOX index had been up 86% year-to-date before that correction^[5].

What makes the $500 billion deal structurally interesting is that it does not solve the demand question — it solves the financing question. Hyperscaler AI capex commitments have been estimated at $1.2 trillion cumulatively^[5], and the market has started to ask whether the companies spending that capital will generate returns on it. Nvidia’s financing platform effectively says: let Wall Street’s capital take the balance-sheet risk, not the hyperscalers’ own.

The mega-cap capex penalty

The other side of the semiconductor rally is the mega-cap selloff, and it has been building since earnings season. On July 29, both Meta and Microsoft reported quarterly results and both are pouring tens of billions into AI infrastructure. The market rendered a split verdict: Microsoft jumped roughly 15% as Azure and Copilot growth signaled AI investments were generating revenue, while Meta dropped roughly 10% as its free cash flow plunged 91% year-over-year to $784 million and revenue guidance missed expectations^[6].

Today’s tape extended that divergence. META fell 2.87% to $581.91 and MSFT dropped 2.23% to $492.59, while the semiconductor makers those companies buy from rallied^[1]. AAPL slid 1.21%, AMZN fell 1.67%, GOOGL dipped 0.77%, and TSLA declined 1.90%^[1]. The pattern is consistent with a market that has begun pricing AI capex as a cost to be penalized when it sits on the spender’s balance sheet, but as revenue to be rewarded when it sits on the supplier’s income statement.

This is not a blanket tech selloff. XLK gained 1.46%^[1]. The divergence is within tech, between the AI capex spenders and the AI capex collectors.

The Iran overhang

The CPI’s disinflationary signal was tempered by an energy market that remains hostage to geopolitics. The US and Iran remain in their fifth month of conflict, with Strait of Hormuz negotiations stalled. President Trump told Axios the US is “only semi-negotiating” with Iran and indicated he would rely on a naval blockade rather than further airstrikes, while Iran’s Foreign Ministry said the US must lift its blockade before Tehran would agree to fully open Hormuz^[7].

Brent crude briefly touched $90 a barrel on Tuesday^[7], and WTI traded around $82.70 on Wednesday^[7]. The US Energy Information Administration estimated that oil disruptions from the Iran conflict would continue through next year^[7]. Oil prices jumped roughly 5% on Monday as doubts grew about a diplomatic resolution^[7].

XLE, the energy sector ETF, slipped 0.19% to $60.82 on Wednesday^[1], and XOM declined 0.44%^[1] — modest moves that suggest the market is not yet pricing a supply shock, but is keeping the risk premium bid. The July CPI’s energy decline of 1.5% month-over-month^[3] may prove temporary if Strait of Hormuz access remains constrained.

What to watch next

• Fed speakers and the September meeting. With headline CPI at 3.4% and core at 2.5%, the rate market will be sensitive to any Fed commentary about whether July’s softness is enough to hold rates steady at the September 16-17 FOMC meeting or whether the energy overhang argues for caution. Kiplinger noted the July report lowered September rate-hike odds^[8].
• Hormuz negotiations. Any movement — or breakdown — in US-Iran talks will move oil and, through it, the inflation expectations embedded in the 10-year yield (currently 4.65%)^[4].
• Nvidia’s financing platform execution. The $500 billion MOUs are agreements to establish platforms, not committed capital. The pace at which deals close and data centers break ground will determine whether the semiconductor recovery sustains or rolls over.
• Mega-cap free cash flow. Meta’s 91% FCF decline^[6] and the broader capex cycle mean Q3 2026 earnings — beginning in October — will be scrutinized for whether AI revenue is scaling fast enough to justify the spend. The market’s current verdict is that the suppliers are the safer bet.
