China Replicates ASML's EUV Lithography Machines with Prototype
According to a Reuters report, China has succeeded in building a prototype EUV (extreme ultraviolet) lithography machine through reverse engineering of ASML systems. The prototype, assembled in a high-security Shenzhen laboratory and finished in early 2025, is now in testing. It can generate EUV light but has not yet produced functioning chips. The project, described as China's version of the Manhattan Project, is coordinated by Huawei and draws on engineers recruited from ASML, including staff working under pseudonyms. Chinese researchers reportedly overcame major hurdles in light sources and system integration, though precision optics remain a weakness. The Chinese government targets working chips by 2028, while project sources see 2030 as more realistic. ASML previously said China would need 'many, many years' to develop such technology. The breakthrough underscores the limits of US-led export controls.
China's success in building an EUV prototype could reshape global AI chip supply chains and challenge US export controls, indirectly affecting AI infrastructure and computing costs across the tech ecosystem, though it lacks direct near-term AdTech/MarTech application.

Key Takeaways & Evidence Grounding
- China built an EUV lithography prototype in Shenzhen via reverse engineering of ASML machines, completed in early 2025 and now in testing.
- The prototype can generate extreme ultraviolet light but has not yet produced working chips.
- Huawei coordinates the project, which involves thousands of engineers and former ASML staff recruited with signing bonuses of 3–5 million yuan ($420,000–$700,000).
- ASML remains the only commercial producer of EUV systems, with machines costing around $250 million each.
- US-led export controls since 2018 have sought to block ASML from selling EUV systems to China.

AI Stocks Sink as OpenAI Revenue Misses Reported Figure
Shares of Nvidia, Oracle, CoreWeave and other AI-related companies fell on Thursday after details emerged about OpenAI's revenue. OpenAI told investors it reached roughly $50 billion in annualized revenue at the end of September, lower than the widely reported $68 billion figure. A person familiar with the matter said the $68 billion figure included gross revenue from partners, making it more comparable to Anthropic. OpenAI also highlighted 77% total run rate growth in Q3 and 107% growth in enterprise business. The company is preparing for a potential IPO, with a valuation of $852 billion, and is in early talks to raise around $30 billion in new funding.
US suspends Microsoft, Adobe from green card labor program
The U.S. Department of Labor announced the suspension of Microsoft and Adobe from its Permanent Labor Certification program, along with Cognizant, Infosys, Capgemini, Tata, Wipro, and HCL. Secretary Keith Sonderling cited active federal investigations for Microsoft and Adobe, and criticized the companies for allegedly taking jobs from American workers. Vice President JD Vance specifically accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft responded by defending its hiring practices, stating that the majority of its U.S. employees are Americans and that most H-1B petitions are for existing employees. The announcement was made during a White House summit on H-1B fraud, coinciding with President Trump honoring several tech CEOs with the National Medal of Science.
TSMC Q3 Revenue Up 51% to Record, Stock Falls
TSMC reported a 51% increase in third-quarter revenue to 1.49 trillion Taiwan dollars (EUR 41.7 billion), surpassing expectations. The semiconductor giant, a key supplier to Apple and Nvidia, continues to benefit from the AI boom and strong chip demand. However, the stock declined despite the record results. The company plans to invest EUR 52-56 billion in expanding its manufacturing facilities this year, including a joint venture with Sony for image sensors. TSMC's market capitalization is approximately USD 2.45 trillion, making it the most valuable company outside the US. The company's growth is also boosting Taiwan's economy, with exports rising over 70% in August and GDP expected to grow 11% in 2026.
