Why American Ambitions in Artificial Intelligence Remain Tied to Taiwan, Regardless of Who Wins Congress

Americans elect all 435 members of the House of Representatives and 35 of the 100 Senate seats on 3 November 2026

Americans are voting on 3 November 2026 for all 435 members of the House of Representatives and 35 of the 100 Senate seats, in a ballot that decides who finances industrial policy.

The stake is not only who controls Congress, but how much it costs and how long it takes to reduce the United States' dependence on advanced chips produced in Taiwan. The thesis of this text is falsifiable: the outcome of the vote may alter the pace of funding and the commercial tone toward China, but it cannot, over a horizon of two to three years, change the geography of leading-edge chip production. The dominant scenario is a managed structural dependence, with the caveat that a crisis in the Taiwan Strait would invalidate any timetable estimate.

1. The mechanism: why a factory cannot be relocated with a vote

The causal chain starts from industrial concentration. The second link is time. The third link is politics. The energy demand of data centres has become a campaign issue: the press has described support for building data centres as one of the administration's controversial policies. The plausible effect is that funding for AI infrastructure becomes more politically contested, not less dependent on imports. The counter-hypothesis deserves weighing. It could be argued that tariff pressure and subsidies accelerate relocation faster than industry history suggests. The data available here are not sufficient to demonstrate either the rapid or the slow variant; the analysis considers the former weaker, because the constraint is physical and human, not only financial. Relocation is a problem of years and engineers, not of parliamentary majorities.

2. What the vote can change for Congress

Donald Trump, President of the United States, is testing support for his agenda in this ballot, two years after returning to the White House in January 2025. He has stated that the results will be better than anticipated for the Republicans. The statement should be read as an electoral signal, not a forecast. On the other side, the press summarising the polls notes that the Democrats appear to be ahead, while noting that polls do not always reflect the result.

A majority in the House requires 218 seats. The campaign themes have been economic: inflation, the war with Iran and economic discontent have put pressure on the Republicans. Luciana Ghica, professor at the Faculty of Political Science of the University of Bucharest, explained in an interview that American elections „differ significantly from the Romanian case” and that only a few contests will be decisive. The interview's title sums up that the political situation will remain unstable regardless of the winner.

For the chip supply chain, instability means budgets negotiated with more difficulty, not a different production map. At the time of writing, 3 November 2026, the vote is under way, and determining the majority may take hours or days. No claim in this text presupposes a result.

3. Scenarios, the effect for Romania and verifiable predictions

The dominant scenario is managed structural dependence. The driver is the difficulty of replacing Taiwan's capacity; the constraint is construction time; the consequence is gradual diversification. The indicator to watch is the share of production outside Taiwan in TSMC's annual reporting. Plausible scenario: a US–China commercial escalation after the elections. The driver is the use of tariffs as a political instrument; the constraint is the cost to American firms; the consequence is volatility in the semiconductor market.

The indicator is the publication of new tariff measures in the official federal register. Tail scenarios: an acute crisis in the Taiwan Strait, with a severe effect on the global chain, and an acceleration of allied diversification beyond the historical pace. For Romania, the channel is indirect: trade, capital flows and a possible flight from risk in markets.

Method, definitions and figures

The figures on the ballot (435 seats, 35 Senate seats, the 218 threshold) come from press reports describing American electoral rules and are not results. "Advanced chips" here denotes semiconductors manufactured on the newest technology nodes, used to train artificial intelligence models; the analysis did not have access to primary TSMC reports or industry data, which is why claims about capacity are flagged.

The probability categories in the table (dominant, plausible, tail) are the editorial team's verbal judgements, based on an uncalibrated internal model; they are not frequencies and have no documented method. The calibration warning applies to all scenarios and predictions in the text.

Limits of the analysis

The analysis cannot establish Taiwan's exact share of global advanced chip production, because primary sources are absent from the available material. The outcome of the election was not known at the time of writing, and the text should be reassessed after the congressional majorities are certified. The diagnosis would be invalidated by a rapid, documented growth of advanced capacity outside Taiwan or by a military crisis in the Strait. The most fragile assumption is that American domestic politics does not change the geography of production in the short term.
