The iShares Semiconductor ETF (SOXX), which mirrors the performance of major chip stocks benefiting from the burgeoning artificial intelligence sector, experienced a sharp downturn of 21.2% in July. This significant decline follows an impressive rally of 112.8% in the first half of 2026, driven by the intense growth in AI technology. Despite strong quarterly results from leading semiconductor companies during July, the index faced a notable correction.
Semiconductor Stocks Hit by Bearish Forecasts, New AI Competition, and Fund Failures
Several factors converged in July to trigger the substantial dip in semiconductor stock values. A prominent bearish forecast came from Michael Burry, renowned for his accurate prediction of the 2008 housing market collapse. Burry publicly disclosed his short positions against the SOXX ETF and individual semiconductor giants like Nvidia and Micron, arguing that AI stocks were considerably overvalued after their rapid ascent. He drew parallels to the dot-com bubble of the late 1990s and the housing boom that preceded the 2008 crash, raising concerns about the sustained momentum of the AI boom.
Adding to the market's unease was the introduction of the Kimi K3 open-source AI model by Chinese lab Moonshot on July 16. This 2.7 trillion-parameter model demonstrated capabilities comparable to, or even superior to, top-tier models from US-based labs like OpenAI and Anthropic in certain applications. While some might view a powerful, cost-effective open-source model as a catalyst for increased AI infrastructure demand, investors instead worried about heightened price competition among AI developers. This concern, in turn, cast shadows on the massive cloud computing commitments these labs have with major US hyperscalers, who are key purchasers of semiconductor chips.
Further exacerbating the selling pressure was the dramatic unraveling of Situational Awareness, an AI-focused hedge fund. Led by former OpenAI researcher Leopold Aschenbrenner, the fund had achieved extraordinary returns of over 400% in the first half of the year, reportedly swelling its assets to $45 billion by June. However, this aggressive performance was fueled by up to 400% leverage on its public market positions. When these positions rapidly reversed, the fund faced margin calls, necessitating forced sales of its holdings. Ultimately, Situational Awareness liquidated its public stock portfolio to the financial behemoth Citadel at a steep discount, amplifying the broader market downturn in AI stocks.
As we examine the current landscape, the question remains whether July's market turbulence for semiconductors is merely a temporary market adjustment within an ongoing AI bull run or a sign of deeper structural issues. Historically, the AI build-out has overcome several periods of investor anxiety, including past concerns over new AI technologies and hyperscaler debt. The consistent strength in recent semiconductor earnings reports and forward-looking statements suggests that demand for AI-related chips continues to accelerate, defying predictions of weakness. This resilience indicates that the AI boom might still be in its nascent stages, despite the recent volatility.
