The S&P 500 extended its losing streak, falling 43.71 points, or 0.58%, to 7,460.14 at market open, as investors continued to rotate out of artificial intelligence-linked stocks while geopolitical tensions in the Middle East intensified. The decline follows Tuesday's close of 7,503.85, where the index had already shed 0.45%, and marks a continued deterioration in market sentiment heading into the latest session. Polymarket traders had priced in the weakness, with the July 8 contract implying just a 12% probability that the index would open higher — a sharp drop from over 50% earlier in the session.

Key Drivers of the Decline

Markets are navigating two significant headwinds: renewed geopolitical risk in the Middle East and uncertainty surrounding the Federal Reserve's policy direction. Investors are closely watching minutes from the Fed's June meeting for further clarity on Chairman Kevin Warsh's first policy meeting, after officials held interest rates steady but signaled additional hikes could follow if inflation remains persistent. Compounding concerns, oil prices surged more than 5% after President Donald Trump declared the U.S.-Iran ceasefire over. Speaking alongside NATO Secretary General Mark Rutte at the alliance's summit in Ankara, Trump stated: "To me, I think it's over. I don't want to deal with them anymore … as far as I'm concerned, it's over." The spike in crude prices has stoked fears that inflation could stay elevated, reinforcing expectations of a prolonged hawkish stance from the Fed.

AI and Semiconductor Stocks Under Pressure

Artificial intelligence-linked stocks remained under significant pressure, with another round of selling hitting semiconductor shares. The VanEck Semiconductor ETF fell more than 3% on Tuesday, reflecting broader anxiety around stretched valuations in the AI sector. The continued rotation out of high-growth technology names has weighed heavily on the broader index, amplifying the downside seen across recent sessions.

Recent Session Performance

The table below captures the S&P 500's performance across recent sessions, highlighting the accelerating decline:

The S&P 500 had opened Tuesday at 7,516.63, below Monday's close of 7,537.43, meaning the July 7 Polymarket contract resolved "Down." That contract recorded approximately $107,040 in traded volume before settling. S&P 500 futures had already pointed to further weakness, declining 0.97% in early Wednesday trading ahead of the open.

Wall Street’s best trade in June was betting against high-flying stocks, specifically Palantir Technologies Inc., Strategy Inc., and Rocket Lab Corp. Inverse exchange-traded funds built to profit from their declines returned 65%, 130%, and 55% respectively, while the S&P 500 slipped about 2%. These gains were driven by leveraged funds designed to rise twice as fast as the underlying stocks fall, producing significant returns as the market darlings reversed course.

The performance data highlights the extent of the declines in the underlying assets. Palantir dropped about 26% during the month, while the Defiance Daily Target 2X Short PLTR ETF rose 66%. Strategy, which moves with bitcoin, tumbled roughly 42%, leading to a 130% surge in the Defiance Daily Target 2X Short MSTR ETF. Rocket Lab sank about 34%, pushing the Defiance Daily Target 2X Short RKLB ETF up about 64% as of midday June 29.

Performance Comparison

The bearish funds climbed toward the top of the Benzinga Edge rankings, a proprietary percentile ranking evaluating price strength. The 2x short Strategy fund scored in the mid-90s, indicating one of the strongest trends in the market, with the bet against Palantir close behind. These signals held across multiple weekly readings, suggesting a sustained trend rather than a single volatile session.

Market Context

The returns from these short funds eclipsed the performance of the S&P 500’s top constituents. Applied Materials Inc., the index’s best-performing stock, gained only roughly 54%, followed by Moderna Inc. near 45% and KLA Corp. around 42%. Even major technology giants suffered losses, with Microsoft Corp. falling about 18%, Amazon.com Inc. and Apple Inc. each around 10%, and Nvidia Corp. about 8%.

Investors should note that these funds are short-term tactical instruments rather than long-term holdings. Each had bled value over prior months, meaning June’s gains represent monthly snapshots rather than cumulative windfalls. The volatility decay inherent in leveraged products makes them suitable only for specific tactical bets rather than buy-and-hold strategies.
