Chinese memory chipmaker CXMT has overtaken Tencent to become China’s most valuable publicly traded company, underscoring how investor enthusiasm for artificial intelligence is rapidly reshaping the country’s stock market.
According to Bloomberg, CXMT’s market capitalization has climbed to approximately $524 billion, surpassing Tencent’s $510 billion following one of the most remarkable IPO rallies of the year. The company’s shares have surged roughly 467% since their public debut at the end of July, making CXMT the biggest beneficiary of China’s AI-driven semiconductor boom.
AI Chip Stocks Continue to Dominate
CXMT’s rapid rise reflects the enormous investor appetite for companies supplying critical AI infrastructure.
As China’s largest producer of memory chips, the company has become one of the country’s most strategically important semiconductor businesses as demand for AI servers and high-performance computing continues to accelerate.
Investors increasingly view memory manufacturers as direct beneficiaries of the global AI investment cycle, helping push valuations across the semiconductor sector sharply higher.
The company’s blockbuster IPO has become one of the defining moments of China’s equity market this year.
Tencent Loses Market Leadership
Tencent held the title of China’s most valuable listed company for years, supported by its dominant positions in gaming, social media, digital payments, and cloud services.
However, investor preferences have shifted dramatically during the AI boom.
Rather than rewarding mature internet platforms, markets have increasingly favored companies building AI infrastructure, including semiconductor manufacturers, cloud computing providers, and data center operators.
Since the beginning of the year, Tencent shares have declined approximately 26%, reflecting both changing investor sentiment and concerns about rising capital spending.
AI Investment Weighs on Tencent Shares
Tencent’s latest quarterly earnings illustrated this shift.
Although the company reported higher revenue and net profit, investors focused on a 176% increase in capital expenditures as Tencent accelerates investment in artificial intelligence infrastructure.
The spending increase contributed to another decline in the stock after earnings, as investors questioned how quickly those investments will generate financial returns.
Despite the market reaction, Tencent’s core gaming business remained strong, with gaming revenue increasing 11% year over year to approximately 65.9 billion yuan ($9.77 billion).
China’s AI Investment Boom Continues
CXMT’s rise above Tencent symbolizes a broader transformation taking place across China’s technology sector.
As artificial intelligence becomes the industry’s primary growth driver, investors are increasingly directing capital toward companies producing chips, AI hardware, computing infrastructure, and related technologies.
The change mirrors trends already seen in the United States, where semiconductor companies have significantly outperformed many traditional software and internet businesses during the current AI investment cycle.
For now, CXMT’s emergence as China’s largest listed company demonstrates just how powerful investor demand for AI infrastructure has become—and how dramatically it is reshaping technology valuations around the world.
