近期，美國華爾街再度掀起一場關於人工智能（AI）概念股泡沫的驚人風暴，而這次事件的中心人物正是以《大空頭/大賣空》聞名的傳奇投資人邁克爾·伯里（Michael Burry）。據其旗下的賽恩資產管理公司（Scion Asset Management）最新披露，伯里已斥資高達10億美元大舉做空人工智能龍頭股——英偉達（NVIDIA）與Palantir，此舉在市場上引起巨大震動。

消息一出，市場立刻反應強烈。英偉達股價在短時間內大幅下跌，使其市值一夜蒸發高達1.4萬億美元，Palantir及其他大型科技股、AI概念股同樣受到波及，出現連鎖下跌。亞太市場亦難以倖免，受到隔夜美股拖累，今日交易時段日本、韓國及其他亞太股市普遍低開低走，其中軟銀集團股價已下跌約10%。

事件的背景是，近幾個月來，市場對AI投資的熱潮與過度炒作現象日益關注。圍繞OpenAI、英偉達及其他人工智能企業的交易活動，出現了被外界形容為“循環交易”的現象，即部分投資者在高估值基礎上反覆交易，推高股價，而這種繁榮被認為是人為支撐，存在潛在泡沫風險。伯里的空頭操作正是對這種現象的直接反擊，他判斷部分AI概念股估值過高、基本面不足以支撐現有股價，因此選擇大手做空。

面對市場壓力，Palantir首席執行官亞歷克斯·卡普（Alex Karp）公開點名伯里，稱其行為“簡直瘋了”，強烈表達對做空操作的不滿與驚訝。此舉在社交媒體及財經圈引發熱議，投資者與分析師紛紛討論伯里的策略是否會引發更廣泛的科技股震盪，甚至影響整個AI板塊的資金流向。

此次事件再次凸顯華爾街對人工智能投資熱潮的兩極分化觀點：一方面，市場對AI的前景抱有高度樂觀預期，視其為長期增長引擎；另一方面，也存在諸如伯里這樣的悲觀派，認為短期內的炒作已遠超企業實際價值，泡沫風險顯著。隨著全球投資者對AI熱潮的關注度升高，未來幾周英偉達、Palantir及其他AI相關公司的股價走勢，可能成為衡量市場情緒與投資理性的重要指標，也可能影響整個科技板塊及資本市場對人工智能的長期信心。

Recently, Wall Street witnessed a dramatic shockwave in the artificial intelligence (AI) sector, centered around legendary investor Michael Burry, famously portrayed in The Big Short. According to the latest filings from his Scion Asset Management, Burry has reportedly invested $1 billion to aggressively short AI-focused tech giants NVIDIA and Palantir, sparking significant market turmoil.

The market’s reaction was swift and severe. NVIDIA’s stock plunged sharply, erasing nearly $1.4 trillion in market value overnight, while Palantir and other major tech and AI-related stocks also suffered losses. The ripple effect extended to Asia-Pacific markets, where Japanese and South Korean exchanges opened lower, dragged down by the U.S. sell-off, with SoftBank shares falling around 10%.

The broader context behind this sell-off involves growing concerns about an AI investment bubble. Over the past several months, trading activity around companies such as OpenAI, NVIDIA, and other AI-focused firms has exhibited what analysts describe as “circular trading,” in which elevated valuations are reinforced through repeated buying and speculative flows. Many market participants fear that these price levels are artificially sustained, creating a disconnect from underlying fundamentals. Burry’s short positions represent a direct challenge to this dynamic, reflecting his view that certain AI stocks are significantly overvalued and vulnerable to correction.

In response to the market pressure, Palantir CEO Alex Karp publicly called out Burry, stating that his actions are “simply insane,” highlighting both surprise and disapproval of the large-scale shorting. The comments fueled intense discussion across social media and financial circles, as investors and analysts debated whether Burry’s moves could trigger broader tech-sector volatility or influence capital flows within the AI space.

This episode underscores the polarized perspectives on AI investing in today’s markets. On one side, investors remain highly optimistic about AI’s long-term growth potential, viewing it as a transformative engine for the technology sector. On the other, pessimists like Burry warn that short-term speculation has detached valuations from reality, raising the risk of a market correction.

In the coming weeks, the price movements of NVIDIA, Palantir, and other AI-related stocks will likely serve as a key barometer of market sentiment and rationality. The outcomes may not only affect the tech sector but could also influence broader investor confidence in AI as a sustainable long-term investment theme.
