Asian Chip Stocks Slide as Broadcom CEO Questions AI Investment

What happened

Hock Tan spoke on Monday 12 October 2026 at the DBS Asia Future Forward Conference in Singapore. According to Bloomberg's reporting, he said that a lot of investors have no clear idea what they are investing in, and that they set very extreme expectations before finding out that the market looks more like a casino. The remarks were widely reported, although no official transcript of the panel has been published. On Tuesday, the sell-off reached chip shares across Asia and Europe. It came on top of Monday's declines in the United States.

Chinese memory chip maker ChangXin Memory Technologies, known as CXMT, added pressure. Over the weekend it said it had made progress on a new chip architecture meant to pack more data into a smaller space. Bloomberg described the company's breakthrough claim as unsubstantiated, but the news still unsettled investors who see Chinese memory makers as a growing competitor to Samsung, SK Hynix and Micron.

The figures differ by source and by time of day. BigGo Finance reported that SK Hynix fell as much as 8.9% in early trading, and some reports put the Nikkei's fall at closer to 2%. Treat the table as a snapshot of closing moves reported on the day, not a settled record.

Why it matters for businesses that automate work

Tan's comments went beyond investor sentiment. He said capital could become the biggest constraint on AI, ahead of chips, memory or power. He also said most companies have not yet found AI uses that pay off, and he compared enterprise spending on AI tokens to a child who spends a set amount in an arcade and learns little. Those points go to the heart of how a business decides what to automate and what to pay a vendor for.

Bloomberg linked the wider selloff to doubts about how long the AI trade can last. A Bloomberg wrap on the day said a closely watched gauge of semiconductor companies had fallen about 17% from its June record. A Bank of America survey of global fund managers, reported by Bloomberg, found that about 45% expected an AI bubble in 2027, while 42% did not.

What changes for a business that automates work, in practice

A share price fall does not switch off the software a company already uses. Invoice matching, follow-up emails, report generation and document handling keep running on the same contracts. What changes is the decision you make next. If your automation depends on a single AI model provider, ask that provider how it is funded and whether its pricing is based on usage. A usage bill can grow faster than expected when a team starts running many automated tasks without limits.

Hardware purchases are the other area to check. If your plans include buying servers or memory-heavy devices in the next few months, the price and supply of memory chips may move with this sell-off. Ask your supplier for the quote date and the validity period, and avoid signing long commitments only because the market has dropped.

There are limits to what this event tells you. One day of falling shares does not show that AI demand is weakening. Analysts quoted by Reuters and others differ on whether the drop reflects real competition or a shift in mood. Broadcom itself expects strong AI revenue growth, with fiscal fourth-quarter AI semiconductor revenue forecast at $21.7 billion, so the company's own numbers do not point to a collapse in demand. Plan on the basis of your own usage data, not on the headlines.

What to watch next

• Whether the US big bank earnings reports, including Citigroup, Goldman Sachs, JPMorgan and Wells Fargo, steady or deepen the market move.
• Whether CXMT's architecture claim is confirmed by independent testing or product launches.
• Broadcom's next quarterly results and whether its AI revenue guidance holds.
• A planned meeting between US President Donald Trump and China's Xi Jinping in Washington, which Bloomberg listed as a market event this week.
