After months of speculation, U.S. President Donald Trump has divulged more of his semiconductor tariff plans, but his latest threats might raise more questions than answers.
On Wednesday, Trump said he will impose a 100% tariff on imports of semiconductors and chips, but not for companies that are “building in the United States.”
As semiconductors represent an over $600 billion industry at the heart of the modern digital economy, any potential tariffs hold massive weight.
However, experts say the President has yet to provide key details on the policy, which will ultimately determine their full impact and targets.
“It’s still too early to pin down the impact of the tariffs on the semiconductor sector,” Ray Wang, research director of semiconductors, supply chain and emerging technology at The Futurum Group, told CNBC.
“The final rule is likely still being drafted and the technical details are far from clear at this point.”
Big players win?
One of the biggest questions for chip players and investors will be how much manufacturing a company needs to commit to the U.S. to qualify for the tariff exemption.
The U.S. has been working to onshore its semiconductor supply chain for many years now. Since 2020, the world’s largest semiconductor companies such as TSMC and Samsung Electronics have committed hundreds of billions of dollars to building plants in the U.S.
Speaking to CNBC’s “Squawk Box Asia” on Thursday, James Sullivan, Managing Director and Head of Asia Pacific Equity Research at J.P. Morgan, said this could mean most major chip manufacturers receiving exemptions.
If this is the case, the policy could have the effect of “continuing to consolidate market share amongst the largest cap players in the space,” Sullivan said.
Indeed, shares of major Asian chip companies like TSMC, which has significant investments in the U.S., rose in Thursday morning trading following Trump’s announcement. Early this year, TSMC announced it would expand its investments in the U.S. to $165 billion.
Shares of South Korea’s Samsung and SK Hynix — which have also invested in the U.S. — were also trading up after a Korean trade envoy reportedly said on radio that the duo would be exempt from the 100% tariffs.
An exemption on what?
Beyond the question of exemptions, many other aspects of the potential tariffs remain unclear.
Speaking on CNBC’s “Squawk Box Asia,” on Thursday, Stacy Rasgon, senior U.S. semiconductor analyst at Bernstein, noted that most of the semiconductors that enter the U.S. come inside consumer goods such as smartphones, PCs and cars.
While Rasgon said tariffs on these imports may be manageable, broader tariffs would be harder to deal with.
“What we don’t know with [Trump’s] comments on tariffs, is it just raw semiconductors? Are there going to be tariffs on end devices? Are you going to be looking at tariffs on components within end devices?,” Rasgon asked.
The confusion and questions around semiconductor tariffs were brought to the forefront after the U.S. Department of Commerce started a national security investigation of semiconductor imports in April, just as the sector was exempted from Trump’s “reciprocal” tariffs.
The vague language from the Trump administration — though not invoked in the president’s latest proclamations — could theoretically be used to apply broad tariffs to an enormous segment of the electronics supply chain. It’s also unclear on the extent that semiconductor materials and manufacturing equipment used to manufacture chips would fall under the tariffs.
Complex supply chains
Potential tariff strategies could also be complicated by the intricate and interdependent nature of the semiconductor supply chain.
Rasgon gave the example of American chip designer Qualcomm, which sends their designs to TSMC to be manufactured in Taiwan and then imported to the U.S.
“Does that mean those [chip imports] would not be tariffed, because they’re made at TSMC, and TSMC is building in the U.S.?… I don’t know. Hopefully that’s how it would be,” he said.
Another large buyer of semiconductors in the U.S. are cloud service providers like Amazon Web Services and Google, which are essential to power Washington’s AI plans.
According to a recent report from ITIF, semiconductors contribute $7 trillion in global economic activity annually by underpinning a range of downstream applications including AI and “big data.”
In a potential sign of American companies seeking to move their chip supply chains into the U.S., Apple CEO Tim Cook, alongside Trump at the White house Wednesday, announced that it will be supplied chips from Samsung’s production plant in Texas.
The company also announced an additional $100 billion in U.S. investments, raising its total investment commitments in the country to $600 billion over the next four years.

Tesla has filed a motion to appeal the verdict in a product liability and wrongful death lawsuit that could cost the company $242.5 million if it is not reduced or overturned.
Elon Musk‘s automaker has asked for the verdict to be tossed or for a new trial in Florida’s Southern district court.
Gibson Dunn, which is representing Tesla in the appeal, argued that compensatory damages in the case should be steeply reduced from $129 million to $69 million at most. That would result in Tesla having to pay a $23 million award if the prior verdict holding the company partially liable for the crash stands up.
The firm also argued that punitive damages should be eliminated or reduced to, at most, three times compensatory damages due to a statutory cap in the state of Florida.
The suit focused on a fatal crash that occurred in 2019 in Key Largo, Florida, in which George McGee was driving his Tesla Model S sedan while using the company’s Enhanced Autopilot, a partially automated driving system.
While driving, McGee dropped his mobile phone and scrambled to pick it up. He said during the trial that he believed Enhanced Autopilot would brake if an obstacle was in the way.

McGee’s Model S accelerated through an intersection at just over 60 miles per hour, hitting a nearby empty parked car and its owners, who were standing on the other side of their vehicle.
The collision killed 22-year-old Naibel Benavides and severely injured her boyfriend, Dillon Angulo.
A jury in a Miami federal court earlier this month said that Tesla should compensate the family of the deceased and the injured survivor, paying a $242.5 million portion of a total $329 million in damages that they decided were appropriate.
In their motion to appeal, Tesla’s lawyers argue that the Model S vehicle had no design defects, and that even alleged design defects could not be blamed for the crash, which they say was caused entirely by the driver.
“For as long as drivers remain at the wheel, any safety feature may embolden a few reckless drivers while enhancing safety for countless others,” the appeal states. “Holding Tesla liable for providing drivers with advanced safety features just because a reckless driver overrode them cannot be reconciled with Florida law.”
Tesla did not respond to a request for additional comment.
Brett Schreiber, lead trial counsel for the plaintiffs in this case, said in a statement that he believes the court will uphold the prior verdict, which should not be seen as “an indictment of the autonomous vehicle industry, but of Tesla’s reckless and unsafe development and deployment of its Autopilot system.”
“The jury heard all the facts and came to the right conclusion that this was a case of shared responsibility but that does not discount the integral role Autopilot and the company’s misrepresentations of its capabilities played in the crash,” he said.

Ambarella stock roared 20% higher Friday as the chip designer reported better-than-expected second-quarter results and issued strong guidance.
Here’s how the company did compared to LSEG expectations:
Earnings: 15 cents per share adj. vs 5 cents per share expected
Revenue: $96 million vs $90 million expected
Ambarella, which is known for its system-on-chip semiconductors and software used for edge artificial intelligence, said it expects third-quarter revenue between $100 million and $108 million, beating the LSEG estimate of $91 million.
The company boosted its fiscal year revenue growth outlook to a range of 31-35%, to $379 million at the midpoint, which topped the $350 million expected by LSEG.
“After a multi-year period of significant edge AI R&D investment, our broad product portfolio enable us to address a rising breadth of edge AI applications,” CEO Fermi Wang said in a call with analysts Thursday.

Wang singled out strength in “portable video, robotic aerial drones and edge infrastructure.”
Edge computing refers to the direct processing and storing of data at the device level instead of those actions being handled remotely in the cloud at a data center.
Ambarella had a net loss of $20 million, a loss of 47 cents per share in the second quarter. That narrowed from the same quarter a year ago, when the company had a net loss of $35 million, a loss of 85 cents per share.
The company said stock-based compensation and the amortization of acquisition-related costs weighed on earnings.
In June, Bloomberg reported that the company was considering a sale and had held talks with banks. Shares climbed 20% higher on the news.

Shares of Marvell Technology plunged 15% on Friday after the artificial intelligence chipmaker’s data center revenue fell short of estimates and it gave lackluster guidance for the current quarter.
Here’s how the company did in comparison with LSEG consensus:
Earnings per share: 67 cents adjusted vs. 66 cents expected
Revenue: $2.01 billion vs. $2.01 billion expected
Revenue jumped 58% from a year ago in the fiscal second quarter that ended Aug. 2, a record for the company that was fueled in part by “strong AI demand” for its custom silicon and electro-optics products, Marvell CEO Matt Murphy said in a statement.
The company had net income of $194.8 million, or 22 cents per share, compared with a net loss of $193.3 million, a loss of 22 cents per share, during the same period last year.
For the fiscal third quarter, the company called for revenue to be $2.06 billion, plus or minus 5%. That was slightly below the $2.11 billion forecast by analysts, according to LSEG.

Marvell is known for creating customized chips and hardware, which it offers to cloud providers such as Amazon and Microsoft.
Sales in its data center segment reached $1.49 billion during the quarter, which fell short of Wall Street’s projected $1.51 billion, according to StreetAccount.
On a conference call with investors, Murphy said the company expects “overall data center revenue in Q3 to be flat sequentially,” which he attributed to nonlinear growth in its custom AI chips business. Fourth-quarter growth is expected to be “substantially stronger” than the third quarter, Murphy said.
He added that “lumpiness” of the guidance is normal as large hyperscalers build out infrastructure.
Still, some investors were hoping for greater clarity around the company’s pipeline of new customers.
“Without this, we find it very difficult underwriting the company’s 20% data center market share target,” Cantor analysts wrote in a Thursday note to clients. “Thus, we wait for more bottoms up granularity before potentially turning more positive.”
Analysts at Bank of America downgraded Marvell’s stock to neutral from buy on Friday and lowered their price target to $78 per share from $90, partly on concerns around the company’s AI growth prospects “in the near/medium term.”
