Nvidia Shares Fund OpenAI Investments While Marvell Targets Google

Masayoshi Son, CEO of SoftBank, recently shared that he shed tears when selling the company's Nvidia shares. This emotional decision, disclosed at a Tokyo forum on December 2, 2025, was driven by SoftBank's strategy to fund significant new artificial intelligence investments, including a major bet on OpenAI and the development of data centers. Son confidently dismissed concerns about an AI investment bubble, projecting that super AI will eventually contribute at least 10% to global GDP. The AI sector continues to see substantial investment and strategic moves. U.S. chipmaker Marvell Technology is reportedly in discussions to acquire chip startup Celestial AI for over $5 billion in a cash and stock deal. Celestial AI's Photonic Fabric technology, which uses light to move data, addresses a critical challenge in training large AI models. This potential acquisition would provide Marvell a distinct advantage over competitors like Broadcom, enabling them to offer hyperscalers such as Google and Microsoft a faster, more power-efficient solution and helping Marvell reach its goal of $2.5 billion in AI sales by 2026. Further demonstrating the robust investment climate, Siren, an investigation company, secured a strategic investment from Elastic on December 2, 2025. This move strengthens their decade-long partnership and will accelerate the development of Siren's AI-driven Investigative Intelligence Platform, designed to assist national security, law enforcement, and financial crime agencies. In Paris, AI voice startup Gradium successfully raised $70 million in seed funding on the same day, led by FirstMark Capital and Eurazeo, with support from investors including Eric Schmidt. Gradium aims to develop faster and more accurate voice models for developers, launching with support for multiple languages and anticipating high demand for its ultra-realistic voice technology. Investment strategies are also evolving to capitalize on AI growth. Schroders strategist Dorian Carrell suggests convertible bonds as a lower-risk entry point into AI, noting these bonds have gained about 15% this year. Carrell describes this as an "asymmetric AI" trade, offering high potential gains with limited downsides, particularly in AI supply chain companies. Major tech firms like Alphabet, Meta, Amazon, and Oracle are actively using debt to fund their AI expansion. The University of Michigan's $17.9 billion endowment reported a 12.3% return rate for the 2025 fiscal year, largely attributed to increased investments in AI and cryptocurrency, viewing AI as the next industrial revolution. Meanwhile, BigBear.ai Holdings shareholders approved increasing authorized common stock to 1 billion shares on December 1, 2025, a move aimed at expanding the company's growth capacity following its $250 million acquisition of Ask Sage, which focuses on secure generative AI for federal agencies. This surge in AI-related activity is also impacting global markets, with AI stocks driving emerging market funds to their best year since 2017. Companies like Taiwan Semiconductor Manufacturing, Alibaba, and Tencent have led gains, though this concentration also presents a risk, with their combined weighting in the Vanguard FTSE Emerging Markets ETF exceeding 18.0%.
