Market Briefing: October 9 — Semiconductor Stocks Slide on OpenAI Revenue Concerns

Semiconductor stocks faced significant pressure following reports that OpenAI’s revenue growth may be lagging behind expectations, fueling broader concerns over the sustainability of massive AI infrastructure investments. Meanwhile, global markets are navigating a volatile landscape shaped by shifting oil prices and fluctuating U.S. bond yields.

Semiconductor stocks drop roughly 4% as reports of OpenAI falling short of revenue targets spark AI investment anxiety.

Markets show mixed signals amid volatility in oil prices and interest rates, prompting capital rotation into energy, consumer staples, and financials.

Key Market Trends

① OpenAI Revenue Concerns Trigger Sell-off in AI and Semiconductor Stocks

Tech stocks faced heavy selling pressure after the Financial Times reported that OpenAI’s annualized revenue as of the end of September reached approximately $50 billion, falling short of its prior forecast of $70 billion.

Growing doubts over whether massive capital expenditure in AI infrastructure can be sustained led to a roughly 4% slide in key semiconductor stocks, including Broadcom, Micron, and AMD.

However, some analysts argue that the disparity may stem from different accounting methods—specifically, that OpenAI excludes sales made through partner companies, unlike some of its competitors.

Given that the company’s revenue is still showing significant year-over-year growth, the market’s reaction appears less about a collapse in AI demand and more about heightened caution regarding the pace of investment and long-term profitability.

② Oil Prices Spike 5% Amid Middle East Volatility

International oil prices surged by more than 5% during early trading, driven by renewed speculation over potential U.S. military strikes against Iran.

The sentiment was further fueled by reports of an attack on an oil tanker north of Qatar, coupled with a larger-than-expected decline in U.S. crude inventories and a hurricane approaching major production facilities.

However, prices pared gains in the afternoon following reports of ongoing dialogue between the U.S. and Iran, which eased some tensions.

The market recovered a significant portion of its losses after Iran stated it would review a U.S. proposal and provide a response within days.

③ Bond Yields Retreat as Treasury Issuance Cycle Concludes

U.S. Treasury yields rose early in the session following hawkish remarks from Federal Reserve officials advocating for further rate hikes.

Fed Governor Christopher Waller and St. Louis Fed President Alberto Musalem both cited persistent inflation as a reason for potential additional tightening.

However, as funds shifted from volatile tech stocks into bonds—and with the three-day, $120 billion U.S. Treasury issuance cycle coming to an end—yields pulled back from their session highs.

Market Outlook

The U.S. market saw a distinct shift in capital allocation rather than a uniform downturn. While six sectors, including energy, consumer staples, and financials, finished higher, five sectors—tech, consumer discretionary, and healthcare—declined.

The most notable movement was the weakness in semiconductor stocks following the OpenAI report. As AI investment expands rapidly, market focus is shifting from simple top-line growth to the profitability required to justify such massive expenditures. That said, given the nuances in revenue calculation and high growth rates, it is premature to conclude that AI demand is cooling.

For the domestic market, the weakness in U.S. semiconductor stocks remains a burden. The MSCI Korea Index fell 4.03%, and overnight futures declined by 1.84%. With Samsung Electronics and SK hynix already experiencing high volatility due to the conclusion of share buyback programs and foreign capital outflows, it is critical to monitor whether this U.S. adjustment leads to further liquidation.

On a positive note, the conclusion of the U.S. Treasury issuance and the slight easing of tensions in the Middle East offer some relief. Provided that interest rates and oil prices do not resume a rapid ascent, there remains potential for sector-specific rotation and stock-picking opportunities even amidst the current adjustment phase.

Today’s Checkpoints

Semiconductors: Reflecting the ~4% slide in Broadcom, Micron, and AMD into Samsung Electronics and SK hynix.

AI Investment: Whether concerns over OpenAI’s revenue translate into broader anxiety regarding AI infrastructure investment.

Middle East & Oil: Progress in U.S.-Iran talks and further volatility in oil prices.

Liquidity: Foreign trading activity following the 4.03% drop in the MSCI Korea Index and the 1.84% dip in overnight futures.
