S&P 500 AI stocks power through U.S. shutdown concerns

Highlights

- S&P 500 closes at 6,740, setting a new record amid strong AI sector gains.

- AMD’s OpenAI chip deal sparks tech rally, offsetting U.S. shutdown uncertainty.

- Index holds bullish trend above 6,638 support, with 6,850–6,900 as next upside target.

The S&P 500 has been in a steady uptrend since April, forming higher highs and higher lows while staying supported by its 20-day exponential moving average (EMA) near 6,638. Monday’s advance brought the index close to the upper boundary of its rising channel at 6,780, a key resistance zone that has repeatedly capped rallies in recent sessions.

A confirmed breakout above this level could extend the move toward 6,850–6,900 in the near term. However, the repeated tests of the upper band and an overbought relative strength index (RSI) reading near 71 suggest the potential for short-term consolidation before another leg higher.

Support remains well-defined, with the 20-day EMA at 6,638 providing an immediate floor. The 50-day EMA at 6,508 offers a secondary cushion, while deeper structural support sits at 6,328, aligned with the 100-day EMA and the channel’s midline. These levels represent key zones where buyers have consistently stepped in to defend the uptrend.

AI-driven strength and macro backdrop

Monday’s gains were fueled by the continued strength of AI-related stocks. AMD surged 23.7% after unveiling a landmark AI chip supply deal with OpenAI, which includes the potential for OpenAI to acquire up to a 10% stake in AMD. The news reinforced investor conviction in the AI hardware sector, sparking broad buying across large-cap technology names.

Microsoft rose 2.2%, Tesla gained 5.5%, and Palantir advanced 3.7%, underscoring the market’s preference for high-growth, AI-exposed stocks. The enthusiasm around artificial intelligence continues to provide a strong offset to the uncertainty stemming from the ongoing government shutdown.

Meanwhile, expectations for Federal Reserve rate cuts later this year have further supported risk appetite. Futures markets now price in a 90% probability of a 25-basis-point rate cut at the upcoming October meeting, with another move expected in December. The dovish outlook has kept Treasury yields subdued, reinforcing the appeal of equities and maintaining liquidity inflows into the market.

Despite political gridlock, investors appear confident that the fiscal standoff will not derail broader market momentum. However, analysts warn that prolonged disruptions could delay key data releases and complicate monetary policy signaling heading into the final quarter of the year.

S&P 500 outlook

Technically, the S&P 500 remains firmly bullish within its established channel. As long as the index holds above 6,638, the broader uptrend remains intact, with the potential for continuation toward 6,850–6,900. A brief consolidation near current levels would be considered healthy after recent gains, helping reset momentum indicators before any renewed breakout attempt.

The RSI above 70 reflects overbought conditions, which may trigger mild profit-taking, but there are no immediate signs of trend exhaustion. The market’s ability to maintain strength in the face of political risk highlights the dominance of structural themes like AI adoption, resilient earnings, and dovish monetary policy expectations.

Short-term caution remains warranted given stretched conditions, yet the long-term bias stays bullish. Traders will watch for reactions near the 6,780 resistance and the 6,638 support band to gauge the next directional move.

Earlier analysis highlighted the S&P 500’s approach toward the 6,750 resistance zone, expecting bullish continuation supported by AI sector flows. The latest breakout aligns with that forecast, confirming that buyers continue to drive the trend despite macro headwinds.
