35% Chip Tax Credit Hangs on Groundbreaking Deadline After Midterms

Qualifying assets that break ground after December 31 are, in principle, shut out of the 35% U.S. semiconductor investment tax credit — and even a Democratic sweep of both chambers on November 4 wouldn't change that overnight. That's the sobering headline from a KOTRA report titled "2026 U.S. Midterm Election Results and Implications," released on the 5th, which warns Korean chipmakers against betting their construction schedules on a legislative fix.

The numbers at stake are large. Samsung Electronics is pouring more than $37 billion (roughly 49.6 trillion won) into Taylor, Texas and other U.S. sites, against a confirmed Commerce Department direct subsidy cap of $4.745 billion. SK Hynix is investing more than $4 billion (about 5.4 trillion won) in West Lafayette, Indiana, to build a high-bandwidth memory packaging hub, with a confirmed cap of $458 million. Those subsidy caps are locked; the tax credit is not.

What does the election actually change?

KOTRA's analysts see genuine bipartisan consensus on one thing: extending the deadline for breaking ground on fab construction. Qualifying assets that begin operation after this year carry the 35% credit rate, but ground broken after year-end is excluded unless Congress acts. An extension would open the door for Samsung and SK Hynix to claim tax support on follow-on facility investments.

Consensus, though, doesn't guarantee amendment. KOTRA drew a sharp line: companies should prioritize meeting current deadlines and eligibility requirements rather than delaying construction in hopes of an extension. The agency also expects tighter scrutiny ahead. With Democrats strengthening oversight, subsidy disbursement reviews and R&D project restructuring face heavier examination, while restrictions on China capacity expansion by subsidy recipients and export controls remain fully in place.

Will EV subsidies come back?

Probably not soon. The U.S. ended tax credits for new, used, and commercial clean vehicles for anything acquired after the end of September last year. Democratic control of Congress improves the climate for restoration talks, but actual revival demands tax law amendments, secured funding — and a signature from President Donald Trump, whose veto looms over any bill. KOTRA stated flatly that a Democratic victory does not translate into revived EV subsidies.

Batteries tell a different story. The production tax credit for qualifying battery production and sales inside the U.S. remains intact. The catch is supply chain eligibility: even U.S.-made output can lose credit access depending on raw material sourcing, component procurement, and supplier ownership ties to countries of concern such as China. For Korean battery makers, KOTRA's message is that managing supply chains to protect existing production credits now outweighs waiting for purchase subsidies to return.

Do the midterms change the reshoring pressure?

Not much, says Kwon Hyo-sung, Bloomberg Economics' economist covering South Korea and Taiwan. Speaking at a Korea Financial Investment Association webinar on the 4th titled "2026 U.S. Midterm Elections and Macro Outlook," he said: "The U.S. government's view on semiconductor reshoring is the same whether Democrats or Republicans are in power, so I don't think it will change significantly." He added that pressure on chipmakers to lift U.S. investment "will not change much either," and that South Korea's and Taiwan's large current account surpluses could stoke Washington's demands for more investment next year.

Are AI data centers the new flashpoint?

Possibly. Tom Orlik, chief economist at Bloomberg Economics, noted at the same webinar: "There aren't many issues that Democrats and Republicans in the U.S. agree on, but one thing they agree on is concern about AI," citing local opposition to data center construction over electricity and water bills. Federal AI regulation remains unlikely under a Trump veto, but governors can slow construction directly.

The proof came on Election Day itself: 41 data center-related referendums in 10 states, 28 of them measures to restrict or ban construction. Jefferies assessed that if a construction-halting candidate wins the Texas governorship — the state holds roughly a quarter of U.S. data center capacity — announced projects totaling 13.3 gigawatts could be disrupted. Taylor, home of Samsung's fab, sits in Texas. Goldman Sachs, though, puts low odds on nationwide halt measures even under Democratic congressional control.

Kwon expects demand to hold: "It is true that it will be harder to build new data centers, but it is not easy to affect data centers that are already being built," and "sites could also be moved to regions with less stringent regulations." His call: data center demand may not decline rapidly, keeping semiconductor demand solid for now.

Investor sentiment is cooling regardless. Orlik diagnosed a shift away from buying anything labeled AI, toward caution about excessive capex and unverified profit structures. Bloomberg Economics modeled a 20% U.S. stock decline plus a one-year data center capex halt; South Korea and Taiwan, the biggest AI beneficiaries, would take the largest economic hits.

Lee Geum-ha, head of KOTRA's North America regional headquarters, said: "Even with Democratic control of both chambers, the tariff stance will be maintained, but in bipartisan areas such as shipbuilding, semiconductors, and power, opportunities may arise for South Korean companies entering the U.S. market." His agency pledges to track legislation and back companies so they don't miss those openings.

Once the vote counts are final, two variables dominate: whether Congress extends the year-end tax credit deadline, and how the data center referendums reshape construction rules — both capable of moving Korean semiconductor and battery investment schedules, and their profitability, directly.
