Taiwan is weighing a major shift in how it handles AI chip exports to China, and markets took notice on Tuesday.

TSM stock opened at $427.11 and rose 2.5% after the U.S. market open, reversing an early premarket dip. The 12-month range sits between $205.87 and $450.16, giving context to how far the stock has run.

The proposed rules, reported by Bloomberg, would restrict AI chip sales above a certain processing power threshold to all Chinese buyers — not just companies already on U.S. blacklists like Huawei.

That’s a meaningful expansion. Right now, such sales are banned under U.S. rules, but Taiwan doesn’t treat violations as a domestic crime. That gap has limited what Taiwanese authorities can actually do when chips end up where they shouldn’t.

Under the framework being discussed, Taiwan would have legal tools to prosecute unauthorized AI chip exports as a criminal offense for the first time.

Taiwan only made its first known detentions of alleged chip smugglers last month, and only on the narrower charge of document falsification. These new rules would go considerably further.

The talks are happening as part of broader trade negotiations with the United States. Senior officials on both sides have not yet signed off on any formal agreement, and details are still being finalized.

Washington has been pushing hard on this front. Last week, the Trump administration moved to close a loophole that may have let advanced chips reach overseas subsidiaries of Chinese companies.

Lawmakers Pile On Pressure

On Monday, senators Jim Banks (R-IN) and Andy Kim (D-NJ) wrote to Bureau of Industry and Security chief Jeffrey Kessler, urging tighter rules on contract chipmakers supplying Chinese firms’ overseas units — a direct reference to companies like TSMC.

The letter reflects growing concern in Washington over the diversion of advanced hardware, including Nvidia-equipped AI servers, from Taiwan to China.

CEO Buying Stock

Away from the geopolitical noise, TSMC’s CEO Che-Chia Wei has been quietly buying stock. On June 5, he picked up 150 ADR shares at $76.01, totaling $11,401.50. He now holds 17,689 shares worth roughly $1.34 million.

It’s his third purchase in as many months. He bought 160 shares in May and 186 in April. Consistent insider buying at that cadence tends to get noticed.

TSMC also recently raised its quarterly dividend from $0.95 to $1.1136 per share — an annualized yield of around 1.0%.

On the institutional side, Tiger Global boosted its TSM position by 49.4% in Q1, adding over 1.8 million shares. T. Rowe Price nearly tripled its stake in Q4, up 168.6%.

Analysts remain constructive. Barclays lifted its price target to $470 with an Overweight rating in April. DA Davidson and Wedbush both carry Buy and Outperform ratings respectively.

The average analyst price target stands at $404.29, below where the stock currently trades.
