ASML wants more money for the machines that make the world's chips, and TSMC is saying no, right as Wall Street lost faith in the AI spending boom that both companies depend on.
TSMC told investors in mid-July it's raising 2026 capital spending 15%, to a range of $60 billion to $64 billion, and lifting its full-year revenue growth outlook to more than 40%. The company pointed to surging demand for AI chips, its 2nm process ramp, and its CoWoS advanced packaging lines. That's one of the largest capex increases TSMC has ever announced in a single guidance update. Then came the twist. The same week, Reuters cited reporting from The Information: ASML is pushing to raise prices on its lithography tools, including a 10% hike on mature deep ultraviolet, or DUV, systems. Some Chinese customers have already agreed to pay it. TSMC, ASML's biggest customer, is reportedly resisting the increase on both its DUV and EUV machines.
ASML makes the machines that etch circuit patterns onto silicon. Nobody else does it at this scale. TSMC needs those machines to build the chips that power Nvidia's GPUs and everything else in the AI supply chain. So when the supplier that has no real competitor starts pushing through price increases the same month its biggest customer is promising Wall Street a bigger AI payoff, that tension is worth watching closely.
ASML has the upper hand here, plain and simple. Its EUV systems, the ones needed for the most advanced chips, are reportedly sold out through the end of 2027. Its CFO, Roger Dassen, has pointed to strengthened pricing power on recent earnings calls. The company is also planning to expand EUV and DUV production capacity by 30% in each of the next two years, according to reporting on its latest guidance raise. When your order book stretches two years out, you don't need to negotiate. You just raise the price and wait for customers to sign.
TSMC's resistance makes sense too. It just told Wall Street its business is stronger than expected. Handing that strength straight back to a supplier in the form of higher tool costs undercuts the story it's trying to tell investors about margin expansion. Somebody eventually eats that 10%. Right now it's a standoff over who.
Then the market panicked #
The ASML standoff landed in the middle of a brutal week for chip stocks. Between July 27 and July 29, semiconductor names shed more than $1 trillion in combined market value, according to CNBC. Nvidia lost $238 billion. SK Hynix dropped $176 billion. Samsung fell $173 billion. Micron shed $113 billion. The trigger was a sudden wave of doubt about whether AI infrastructure spending is starting to peak faster than expected, compounded by SK Hynix reportedly delaying an HBM4 memory expansion in favor of DDR5 production.
Then there was CXMT. ChangXin Memory Technologies, a Chinese state-backed memory chipmaker, debuted on Shanghai's STAR Market on July 27, pricing its IPO at 8.66 yuan a share and raising roughly 57.9 billion yuan, or about $8.6 billion. It was the largest mainland China listing since Agricultural Bank of China's IPO in 2010, and Asia's biggest listing so far this year. The stock popped roughly 466% on its debut, according to CNBC, briefly making CXMT one of the most valuable tech companies listed in China at a market cap near $480 billion. For a market already nervous about whether AI capex will pay off, a homegrown Chinese memory rival suddenly worth nearly half a trillion dollars read as one more reason to sell first and ask questions later.
Who ends up paying #
None of that changes what's happening between TSMC and ASML. It just raises the stakes of it. If TSMC is spending $64 billion next year and its own equipment supplier is trying to squeeze more out of every purchase order, that cost has to land somewhere. It shows up in wafer prices, then in chip prices, then eventually in whatever device you're holding that runs on TSMC silicon. Investors spent last week questioning whether AI spending will ever pay for itself. This week's real answer might come down to whether TSMC can hold the line with the one supplier it can't walk away from.
Neither TSMC nor ASML has publicly detailed how the pricing dispute will resolve. For now, TSMC is still building at record pace and ASML's order book is still full through 2027. The disagreement over who pays for that growth hasn't been settled. It's just been delayed.
