Global financial markets are experiencing sharp movements. Nvidia has invested $2 billion in Coherent and supported Ayar Labs with $500 million, reinforcing the trend of AI technology development. Meanwhile, the South Korean stock market is experiencing its worst session since 2008, forcing a trading halt. In the background, American importers are preparing for tariff refund disputes after a court rejected the government's attempts to delay procedures.

Nvidia's Investment Offensive

The corporation allocates billions to photonics and energy-efficient chips, strengthening its dominance in the AI hardware sector.

Stock Market Crash in Korea

Dispute Over US Tariff Refunds

A federal court sided with businesses, rejecting the government's attempt to delay tariff refund procedures.

PayPay's Nasdaq Debut

The Japanese payment company plans a $1.1 billion IPO on the US market.

Early March 2026 brings a series of events redefining the technological and trade landscape. The semiconductor giant Nvidia announced a strategic $2 billion investment in Coherent, a company specializing in photonic technology. Concurrently, the startup Ayar Labs, backed by the corporation, secured $500 million at a valuation reaching $3.75 billion. These moves indicate the growing importance of efficient data transmission using light in artificial intelligence infrastructure. Meanwhile, in the cloud infrastructure sector, Amazon, through its data center unit, acquired the George Washington University campus in Virginia, confirming the relentless pace of physical backend expansion for AI systems. Silicon photonics technology, which Nvidia is investing in, has been developed since the beginning of the 21st century as a solution to bottlenecks in inter-processor communication, replacing copper connections with integrated circuit-level optical fibers. Completely different sentiments prevail in Asian markets. The trading session in Seoul has been termed a "crash" after major indices recorded their largest declines since the 2008 financial crisis. Investor panic forced regulators to temporarily suspend trading. At the same time, in Japan, the government is taking steps to enhance national security by establishing a panel on intelligence capabilities and regulating land purchases by foreigners. Another significant market news is the planned IPO of PayPay, a SoftBank group company, aiming to raise $1.1 billion on the New York Nasdaq at a valuation exceeding $13 billion. Since the Asian financial crisis in 1997, Pacific region economies have implemented a series of stabilization mechanisms, such as "circuit breakers," which automatically halt trading in case of excessively sharp declines. In the United States, tension is rising between the government administration and the business sector. Companies are preparing for a legal battle over tariff refunds after a federal court rejected the administration's request to slow down refund processes. Businesspeople complain about a "crazy level of uncertainty" related to trade policy. The situation may be calmed by trade talks between US and Chinese officials planned for mid-March, which are to precede a summit involving Donald Trump and Xi Jinping. Simultaneously, the US Commodity Futures Trading Commission (CFTC) announces it will accelerate work on regulations for prediction markets, which Nasdaq's operator, among others, plans to enter. „The level of uncertainty is crazy” — American business representative
