CXMT, a Chinese memory chipmaker, saw its shares surge by an astounding 470% during its Shanghai trading debut on July 27, 2026, after Asia's biggest IPO this year. The company raised $8.6 billion ($57.92 billion yuan) with an offering priced at 8.66 yuan per share. This explosive debut catapulted CXMT's market capitalization to 3.3 trillion yuan ($487.73 billion), briefly making it China's most valuable listed company, surpassing banking giant Industrial and Commercial Bank of China. This rapid rise has sparked fears of a potential bubble, especially given concerns about stretched valuations in the global tech sector.
However, analysts suggest the IPO's impact, particularly on the STAR Market and among semiconductor and AI stocks, is more of a temporary liquidity drain rather than a permanent market shift. Benjamin Cavender, managing director at CMR Consulting, attributed this to a "cash call" effect, where investors rotate out of existing holdings to free up cash for highly anticipated offerings. China's market is particularly susceptible to this due to its large retail investor base, accounting for about 90% of daily trading, and its lottery-style IPO allocation system. The direct liquidity impact is expected to be temporary, with cash likely returning to the market once allocations are completed.
Tim Sun, senior researcher at HashKey Group, noted that the listing reinforced worries over a liquidity squeeze as investors expected CXMT's valuation to rapidly exceed $139 billion (1 trillion yuan). Counterpoint Research views the IPO as a longer-term strategic move, expecting the capital raised to accelerate CXMT's capacity expansion and strengthen its position in the global memory market. By 2025, CXMT was the world's fourth-biggest DRAM memory chipmaker with roughly 6% of the global market, and its share is forecast to reach 11% by 2028, though 15% is seen as necessary for long-term competitiveness. CXMT's strategic importance is magnified by its role in China's AI push amidst US export controls, which have restricted China's access to advanced chips.
Some analysts, like Yuan Yuwei of Trinity Synergy Investments, expressed skepticism about the sustainability of the optimism, calling the stock "too expensive" and suggesting it "smells of speculation." Yet, Jing Jie Yu, an equity analyst at Morningstar, pointed out that investor appetite is driven by the desire to gain exposure to the current memory supercycle. CXMT's first-half revenue is expected to surge to between 110 billion yuan and 120 billion yuan, with a net profit of 66 billion yuan to 75 billion yuan, reversing a previous year's loss.
