US Midterm Elections 2026: What the Results Could Mean for Stocks, Gold and the US Dollar

Key Takeaways

• The 2026 US midterm elections take place on November 3, with all 435 House seats and 35 Senate seats being contested.
• Prediction markets strongly favor Democrats winning the House and currently give the party about a 70% chance of controlling both chambers.
• A Democratic sweep could increase regulatory pressure on AI companies, banks and cryptocurrency firms while limiting further fiscal expansion.
• A Republican sweep would be a larger market surprise and could initially lift Treasury yields and the US dollar while pressuring gold.
• The election may create short-term volatility, but the October jobs report and Federal Reserve expectations will likely determine whether market moves persist.

The US midterm elections 2026 arrive at a sensitive moment for global markets. Technology stocks are falling, investors are questioning the returns from record artificial-intelligence spending, and persistent inflation has kept another Federal Reserve interest-rate increase on the table.

The November 3 vote will determine control of Congress for the remaining two years of President Donald Trump’s term. The result could influence fiscal policy, AI regulation, energy spending and expectations for government borrowing, with potential consequences for stocks, gold, Treasury yields and the US dollar.

What Is at Stake in the 2026 Midterm Elections?

Voters will elect all 435 members of the House of Representatives and 35 of the Senate’s 100 members. Elections will also be held for 36 governorships and numerous state offices.

Republicans currently control the White House and both chambers of Congress. A Democratic victory in either chamber would create divided government and make it more difficult for the administration to pass legislation covering taxation, spending and regulatory policy.

Prediction-market probabilities have moved decisively toward Democrats. As of November 2, they showed approximately a 93% to 95% probability of Democratic House control and a 71% to 72% chance of the party winning the Senate. Separate contracts placed the probability of Democrats capturing both chambers at around 70%.

These figures represent market-implied expectations rather than election forecasts. Their importance is that a Democratic House is already largely reflected in asset prices, meaning the strongest market reaction would probably follow a result that differs substantially from that assumption.

How Could Each Election Result Affect Markets?

The immediate reaction will depend on whether the outcome changes expectations for fiscal spending, regulation and government borrowing.

A clear result could provide some relief simply by removing uncertainty. However, a larger-than-expected Democratic victory may initially weigh on technology stocks because investors would anticipate greater scrutiny of AI data centres, energy consumption and industry concentration.

AI Stocks Face the Greatest Election Risk

The election follows a sharp technology sell-off. The S&P 500 declined 1.8% on Friday, while the Nasdaq Composite lost 2.9% after earnings from Alphabet, Amazon and Intel intensified doubts about the returns generated by enormous AI capital expenditure.

A Democratic Congress could hold additional hearings or pursue rules covering data-centre electricity use, environmental impacts, competition and AI safety. Banks and cryptocurrency companies could also face greater regulatory attention.

State and local elections may be equally important for the data-centre industry because local governments control tax incentives, electricity approvals and construction permits.

Nevertheless, major federal restrictions could be difficult to enact without the president’s support. Any election-driven decline in AI stocks may therefore prove temporary unless the result changes corporate spending plans or expected profitability.

What Could the Election Mean for Gold?

The relationship between elections and gold is not straightforward.

A Democratic Congress could restrict deficit-expanding tax and spending legislation. Lower anticipated borrowing could reduce long-term Treasury yields and weaken the dollar, both of which would generally support non-yielding gold.

However, improved fiscal discipline could also reduce demand for gold as protection against government debt and currency depreciation. If Democratic control encourages de-escalation in the Middle East, lower oil prices may reduce inflation and Fed rate-hike expectations but also weaken geopolitical safe-haven demand.

A Republican sweep could initially push gold lower by lifting yields and the dollar. Over a longer period, however, renewed fiscal expansion and higher deficits could strengthen the structural argument for holding bullion.

The World Gold Council notes that gold has historically reacted more strongly to the economic, fiscal and monetary policies implemented after elections than to the results themselves.

Will the US Dollar Rise After the Midterms?

The US Dollar Index entered election week near 101.94 as major currencies remained range-bound.

A Republican sweep would be the most clearly bullish result for the dollar because unified government could preserve the possibility of further tax cuts or spending increases. Those policies could lift inflation expectations, Treasury issuance and US yields.

A Democratic sweep is already substantially priced in. Unless the victory is much larger than expected, the dollar’s reaction could therefore be limited. A divided Congress would also leave many existing tariff and trade policies under presidential control.

The election should be viewed as a catalyst rather than a standalone dollar driver. Interest-rate differentials, oil prices and Federal Reserve expectations are likely to have a larger and more durable effect.

Jobs Data Could Quickly Replace the Election as the Main Catalyst

Markets will receive the October US employment report on November 6, only three days after the election.

Economists expect nonfarm payrolls to increase by approximately 63,000, with unemployment holding at 4.2% and average hourly earnings rising 0.3% month over month.

A stronger report could revive December Fed rate-hike expectations, lifting Treasury yields and the dollar while pressuring technology stocks and gold. A weaker report could produce the opposite reaction.

The election may determine the initial direction of markets, but employment, inflation and corporate earnings will decide whether that move develops into a lasting trend.
