Why Are US Stock Index Futures Down Pre-Market? Oil Breaches $100; Apple, Tesla, Google in Focus

TradingKey - In US premarket trading on September 9 ET, futures tied to the three major stock indexes fell across the board. As of press time, Dow Jones futures fell 0.54%, S&P 500 futures dropped 0.26%, and Nasdaq 100 futures slid 0.35%.

Rising oil prices and higher US Treasury yields became major market drivers in premarket trading. Brent crude futures broke above $100 per barrel during the session, reclaiming this threshold for the first time since July, while WTI crude also rose above $94. The 10-year US Treasury yield climbed to near 4.8%.

A further escalation of the situation in the Middle East was a major factor driving oil prices higher that day. U.S. Central Command struck five Iranian oil tankers on Tuesday, after which Iran launched a new round of attacks on U.S. military targets in the Middle East, escalating market concerns over crude supply and shipping safety in the Strait of Hormuz.

U.S. August PPI and CPI data will be released on September 10 and 11, respectively. CME's FedWatch Tool shows that the market currently places the probability of a 25-basis-point Fed rate hike in September at around 60%. With oil prices breaking above $100 once again, the impact of this week's inflation data on rate expectations is attracting heightened attention.

Foldable iPhone Gains Attention as Apple Event Approaches

Apple (AAPL) fell 1.17% on September 8 to close at $316.22. As of press time, it was down a slight 0.34% in pre-market trading on September 9.

Apple will hold its autumn new product launch event on September 9 local time, which will also be its first major product event since John Ternus succeeded Tim Cook as CEO on September 1.

According to media reports, Apple is expected to introduce its first foldable iPhone at the event, with the market generally expecting it to be priced above $2,000. However, the final product name, pricing, and release date have yet to be officially announced by Apple.

In addition to the foldable device, the iPhone 18 series and the latest developments in Apple's AI features are also key highlights of the launch event. Whether the pricing of new products and the foldable iPhone can stimulate high-end upgrade demand, as well as whether Apple can demonstrate more attractive AI features, will be the focus of investors.

Tesla: Musk Says Cybercab Production Efficiency Improves

Tesla (TSLA) rose 3.98% on September 8 to close at $368.16. As of press time, it was down 1.08% in pre-market trading on September 9.

Musk stated on X that Tesla has redesigned the Cybercab production process, claiming its manufacturing speed is more than five times faster than traditional automotive manufacturing methods. However, Tesla has yet to release mass production data to verify whether this production efficiency can be sustained at scale.

ARK Investment Management estimates that once Tesla Robotaxi achieves scaled operations, the service price could be as low as approximately $0.25 per mile.

Goldman Sachs maintained its "Neutral" rating on Tesla and a $360 price target. The firm believes that autonomous driving software performance and whether Robotaxi can expand its operational scope are more critical to commercialization prospects than the manufacturing cost advantage of the Cybercab itself.

Morningstar, meanwhile, maintained its fair value estimate of $450 for Tesla while assigning a "Very High" Uncertainty rating.

Google: $15.1 Billion to Expand AI Infrastructure Investment in Finland

Google (GOOGL) closed at approximately $338.39 on September 8, virtually flat. As of press time, it was down 2.37% in pre-market trading on September 9.

On September 9, Google announced that it would invest at least 13 billion euros (approximately $15.1 billion) in Finland between 2027 and 2028, marking its largest single investment in Europe to date. The project covers four locations—Hamina, Kajaani, Muhos, and Vaala—including the construction of new data centers and related supporting infrastructure to support services such as Gemini, Search, Maps, and YouTube.

Power supply is also a key component of this investment. Google has signed a 22-year nuclear power purchase agreement with Finnish energy company Fortum, while increasing onshore wind power procurement and contracting a 94 MW battery energy storage system. These energy projects will provide long-term power assurance for Google's expansion of its data center operations in Finland while enhancing local grid stability.

Alphabet is currently in a high capital expenditure phase. In the second quarter of 2026, the company's capital expenditure reached $44.9 billion, and its full-year capital expenditure guidance was subsequently raised to $195 billion to $205 billion. As capital expenditures for the quarter exceeded operating cash flow, free cash flow dropped to approximately -$5.9 billion, marking the company's first negative quarterly free cash flow since its IPO.

Google Cloud's second-quarter revenue grew 82% year-over-year to $24.8 billion. As of the end of June, Google Cloud's revenue backlog reached $513.9 billion, reflecting a substantial volume of signed customer contract commitments that have not yet been recognized as revenue.

As Alphabet continues to scale up its investment in data centers and AI computing power, the market will focus on whether the additional computing power can bring sufficient revenue and profit growth. Whether Google Cloud can sustain rapid revenue and profit growth, and when Alphabet's free cash flow will recover, will influence market judgment on the returns from this round of high capital expenditures.

Summary

In U.S. premarket trading on September 9, inflation concerns sparked by rising oil prices and shifting interest rate expectations remained key factors influencing the broader market. After Brent crude broke above $100 intraday, the importance of this week's PPI and CPI data has heightened further.

Among individual stocks, Apple's product launch event is approaching, with a foldable iPhone and AI features as the main highlights. Tesla gained nearly 4% in the previous trading session, as Musk's comments on accelerating Cybercab production and progress in Robotaxi commercialization continued to draw attention. Meanwhile, Google announced an investment of at least 13 billion euros in Finland to further expand its AI infrastructure.

In the short term, U.S. inflation data, oil prices, and U.S. Treasury yields may still impact risk appetite in U.S. equities. Among tech stocks, whether Apple's new products can drive upgrade demand, and whether Alphabet's massive AI infrastructure investments can translate into sustained revenue and profit growth, remain key areas to watch.
