The semiconductor world is buzzing. China just took a giant leap. A Shanghai-based company has started mass-producing immersion deep ultraviolet (DUV) lithography tools. These machines are exactly the kind ASML, the Dutch leader in chip equipment, is barred from selling to China. This breakthrough is shaking up global chip markets and sending shockwaves through stock exchanges.
ASML’s Market Share Takes a Hit
ASML’s shares plunged 6.5% on July 27, 2026, right after news broke about China’s new DUV production. China’s slice of ASML’s sales shrank from 19% in the first quarter of 2026 to 14% in the second quarter. Earlier in the year, China was still ASML’s biggest market. But now, the landscape is shifting fast.
The Dutch government is cracking down on ASML’s shipments. Under pressure from the US, it restricts exports of ASML’s most advanced lithography machines, including the NXT:2050i and NXT:2100i systems. The US aims to cut off China’s access to the most sophisticated chipmaking tools. The MATCH Act would force the Netherlands and Japan to align their DUV export policies with the US rules within 150 days.
These export controls are designed to slow China’s chip ambitions. Yet, the Shanghai-based company’s new machines challenge that goal. “The machines are the type that ASML has been restricted from selling to China under Dutch and US export controls,” experts note. This move could reshape global chip equipment supply chains.
China’s CXMT Rockets on the Chip Stage
Meanwhile, Chinese chipmaker CXMT (ChangXin Memory Technologies) is stealing the spotlight. CXMT launched its IPO on July 27, 2026, in Shanghai and raised at least $8.6 billion. Its shares soared about 470% in midday trading. Some reports say the shares jumped 466% at IPO, while others note gains nearing 500% post-IPO. That’s a staggering debut!
Founded in 2016 in Hefei, China, CXMT is now one of the world’s largest DRAM makers. It held roughly 6% of the global DRAM market by shipments in 2025, ranking as the fourth biggest player. In the first quarter of 2026, CXMT’s revenue exploded to 50.8 billion yuan ($7.5 billion), a more than 700% increase year-on-year.
Its global market share was around 9% in Q1 2026, and forecasts project it will hit about 11% by 2028. Kyle Chan, a Brookings Institution fellow, said, “CXMT plays a critical role in China’s AI push, particularly in the face of U.S. export controls.” But challenges remain. MS Hwang from Counterpoint Research warns, “Trade restrictions on tools are remaining as the key challenge for CXMT.”
The Pentagon labels CXMT as having links to the Chinese military. US lawmakers are even calling to block American companies from buying CXMT’s memory chips. Yet, its market debut shows strong investor confidence in China’s domestic chip capabilities despite export hurdles.
The Bigger Picture: Global Chip Tensions and AI Race
The chip war is heating up. South Korea’s SK Hynix also went public in July 2026, raising $26.5 billion. The stakes are sky-high as chipmakers race to dominate memory production.
And it’s not just hardware making headlines. AI companies are under scrutiny too. A White House official accused the Chinese AI firm Moonshot of accessing Nvidia’s chips despite export bans. Meanwhile, Nvidia and Microsoft launched a new AI security alliance that notably leaves out giants like OpenAI, Google, and Anthropic.
The semiconductor battlefield is tightly linked to AI advancements and national security. As China pushes to close the chip gap, global powers are tightening controls. That makes China’s ability to produce key lithography tools a game-changer.
Looking Ahead
What’s next? The semiconductor industry is poised for a major shakeup. China’s mass production of immersion DUV tools could weaken Western export controls and reshape supply chains. CXMT’s soaring market debut signals China’s growing self-reliance in memory chips. But trade restrictions and geopolitical tensions will keep the pressure high.
Will China’s chipmakers turn the tide in this high-stakes race? Can export controls keep pace with rapid technological advances? One thing’s clear: the global semiconductor game is entering a new, intense phase. The next moves will redefine the future of chips and AI worldwide.
