first_img Goldman Sachs: Optical networks are the next trend in AI infrastructure, with TAM increasing 9 times to 154 billion USD

Goldman Sachs' Global Technology Equity Research Team released a report on April 17, 2026, stating that networks unlock the computing power of a single AI chip by connecting multiple chips, enabling seamless data exchange and low latency. With the expansion of AI infrastructure and the enhancement of computing power, various configurations are expected to see growth, further opening up a 9-fold Total Addressable Market (TAM) space to $154 billion.The report pointed out that the dollar content of horizontal and vertical scaling increases by 16 times and 45 times, respectively; the TAM for optics expands 13 times from horizontal to vertical scaling; the market value of pluggable optical modules in horizontal scaling expands 10 times from AI server models in the second half of 2025 to models in the second half of 2027. The authors include Allen Chang, Verena Jeng, James Schneider, Mark Delaney, among others.The total dollar content for each computing unit in vertical and horizontal scaling is expected to increase from $315,000 for GB300 NVL72 to $9.4 billion for Rubin Ultra NVL576, a 29-fold increase. The total value TAM increases 9 times to $154 billion (mainly in 2028), of which 69% ($106 billion) comes from vertical scaling. The analysis covers the dollar content and market opportunities of configurations such as copper cables, pluggable optical modules, CPO, and PCB backplanes.

first_img The British judge rejected the extradition defense of the former CEO of Saitama, and the case has been transferred to the UK government

According to a report by Reuters, British judge Samuel Goozee dismissed the extradition defense of former Saitama CEO Manpreet Kohli on August 19 and transferred the case to the UK government to make a decision on the US extradition request. Kohli can still appeal, and the extradition has not been finalized; he is currently released on bail set at £200,000 (approximately $272,400).US prosecutors have charged Kohli with wire fraud, market manipulation, and related conspiracy, as well as operating an unlicensed remittance business, involving the Ethereum-based token Saitama, which once had a market value of about $7.5 billion. Kohli defended himself by arguing that the US could not adequately handle his mental health and the risk of suicide during detention, but the judge believed that the transfer and the safeguards of the US prison system could reduce the risk to an acceptable level. Previously, a federal judge in Boston had also dismissed his motion to dismiss the charges.The case stems from the "Operation Token Mirrors" investigation initiated by the US Department of Justice in October 2024, involving fraud and wash trading. Prosecutors allege that 18 individuals, including Kohli, coordinated multiple wallets to purchase tokens and paid ZM Quant and Gotbit to conduct wash trading on several exchanges, with Kohli suspected of profiting about $20 million. Gotbit has admitted to manipulating token prices and trading volumes and was ordered to pay $23 million in June 2025, while its founder Aleksei Andriunin was sentenced to 8 months in prison.
