暴跌40%！软银成为“OpenAI链”风向标

Core Viewpoint - The stock price of SoftBank Group has become a key indicator of market confidence in the non-public company OpenAI, amid rising concerns over overvaluation in the AI sector and changes in industry competition dynamics [1][3]. Group 1: SoftBank's Stock Performance - Since the end of October, SoftBank's stock has plummeted approximately 40%, resulting in a market value loss of over 16 trillion yen (about 102 billion USD) [3]. - The recent sell-off is primarily driven by market anxiety regarding competitive pressures faced by OpenAI, especially following the release of Alphabet's highly praised Gemini 3.0 model [3][9]. - The stock's decline reflects SoftBank's sensitivity to OpenAI's valuation and market position rather than a general downturn in the AI sector [9]. Group 2: Financial Implications and Investments - SoftBank previously benefited from its deep exposure to the AI sector, recording an unrealized gain of 14.6 billion USD from its investment in OpenAI, leading to a surprising net profit of 2.5 trillion yen in the second fiscal quarter [5]. - However, this same exposure has made SoftBank vulnerable to fluctuations in the AI industry [6]. - SoftBank is committed to paying 22.5 billion USD to OpenAI in December, part of a total investment commitment of 32 billion USD, which could represent over 20% of its net asset value if OpenAI's valuation reaches 500 billion USD [9]. Group 3: Strategic Moves by Masayoshi Son - Masayoshi Son aims to build a comprehensive AI ecosystem, going beyond being a financial investor in OpenAI, by engaging in various mergers and investments [10]. - SoftBank has sold shares in Nvidia and Oracle to raise funds for its AI chip and infrastructure strategy, believing that future devices will require high-efficiency AI chips [11]. - The company has acquired nearly 90% of Arm and completed a 6.5 billion USD acquisition of Ampere Computing, a server processor manufacturer [11]. Group 4: Market Dynamics and Investment Logic - The market is witnessing a shift in AI investment logic, moving away from indiscriminate buying of AI-related stocks to a more selective approach [13]. - Reports indicate that companies like Meta Platforms Inc. are planning to use Google's Gemini AI chips, raising concerns for Nvidia's business and affecting its Japanese suppliers [13][14]. - Conversely, companies like Toppan Holdings Inc. have seen stock price increases due to their partnerships in AI chip design, indicating a more nuanced evaluation of winners and losers within the AI supply chain [14].
