US Midterms Shape Africa and Latin America

US MIDTERMS · LATIN AMERICA · AFRICA

On Tuesday 3 November 2026 Americans vote for all 435 House seats, 35 of 100 Senate seats and 36 governorships. Polymarket bets favour Democrats for the House (94.5%) and Senate (76.5%) at 4:32 a.m. ET; first polls close 6 p.m. ET.

What Is on the Ballot Today

All 435 House seats are on the ballot, and 218 seats make a majority. The Clerk of the House lists two vacant seats, in Florida’s 20th and Texas’s 23rd districts.

In the Senate, 35 of 100 seats are up, and Republicans hold 53 against 47 for Democrats and their two independent allies. Democrats need a net gain of four seats to reach 51, because the vice president breaks 50-50 ties.

Thirty-six governorships are also on the ballot, and each state runs its own voting and count. Two of the 35 Senate contests are special elections, in Ohio and Florida, for seats vacated in January 2025.

A law needs both chambers and the president’s signature, so a split Congress can block the other side. Overriding a veto takes two-thirds of each chamber, a threshold neither party holds today.

In Georgia a candidate needs a majority to win. If nobody gets one, a runoff would be held on Tuesday 1 December 2026.

Poll Closing Times and When Results Arrive

The first polls close at 6 p.m. ET in parts of Indiana and Kentucky. Georgia, South Carolina, Vermont, Virginia and most of Florida follow at 7 p.m. ET.

Ohio, North Carolina and West Virginia close at 7:30 p.m. ET, and the largest batch of states at 8 p.m. ET. More states close at 9 and 10 p.m. ET.

Western states, including California, Oregon and Washington, close at 11 p.m. ET. Hawaii and most of Alaska close at midnight ET, and the western Aleutian Islands at 1 a.m. on Wednesday 4 November.

Florida, North Carolina and Georgia usually count quickly, while Michigan, Wisconsin and Pennsylvania can take longer. Calls in close races may wait until Wednesday 4 November or later.

In Brasília and São Paulo the first closings come at 8 p.m. Tuesday, and the big wave two hours later. In Mexico City the first closings come at 5 p.m., one hour before ET, and Bogotá matches ET.

In Lagos the first closings fall at midnight, and the 8 p.m. ET wave at 2 a.m. on Wednesday. Johannesburg is at 1 a.m. and 3 a.m., and Nairobi at 2 a.m. and 4 a.m.

Where the Results Stand

As of the morning of Tuesday 3 November 2026, no polls have closed and no results exist. This section will carry the House and Senate tally after polls close tonight.

Only the first two sentences and this section change when results arrive; every other section stays valid. Official results come from state election offices, and certification can take days or weeks.

The Clerk of the House publishes the official list of members, and the Senate does the same for senators. Recounts in close races can delay the final tally beyond Wednesday 4 November.

What Prediction Markets Say

At 4:32 a.m. ET on 3 November, Polymarket, a US prediction market, priced a Democratic House at 94.5%, with US$43.0 million traded. It priced a Democratic Senate at 76.5%, with US$18.4 million traded.

Its balance-of-power market, with US$61.6 million traded, gave Democrats both chambers 75.5% and a Democratic House with a Republican Senate 18.5%. Republicans keeping both chambers stood at 5.5%.

Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.

What It Means for Latin America

Most US tariffs now rest on executive powers, so a vote for Congress does not change them overnight. Section 301 duties of 10% or 12.5% on 60 economies took effect at 12:01 a.m. ET on 24 July 2026.

The US Trade Representative’s notice sets Brazil, Chile, Colombia and Peru at 12.5%. Mexico is in the lower 10% tier, and the notice lists exclusions for some products.

A Democratic House could hold hearings and use spending bills to question tariffs and deportation funding. It cannot remove either alone, because the Senate and the president must also agree.

A 1% US tax on cash remittances has applied since 1 January 2026 under the 2025 budget law, Public Law 119-21. Transfers from bank accounts and cards are exempt, so the tax falls mainly on cash senders.

What It Means for Africa

Section 301 duties of 12.5% apply to Algeria, Angola, Egypt, Libya, Morocco, Nigeria and South Africa, the notice says. Kenya, Ghana and Ethiopia are not among the 60 economies covered.

The African Growth and Opportunity Act (AGOA) gives eligible sub-Saharan countries duty-free access to the US market for many goods. It was extended on 3 February 2026, retroactive to 30 September 2025, and now expires on Thursday 31 December 2026.

A stopgap spending law, H.R. 6500, signed on Wednesday 2 September 2026, funds federal agencies through Friday 11 December. Full-year funding for State Department and aid programmes is still undecided.

The Congress elected today takes office on Sunday 3 January 2027 and will shape 2027 aid and trade bills. It can renew AGOA, but only with the Senate and the president, who also decide how long any renewal lasts.

What It Means for You

If you export to the US, check your country’s Section 301 tier, 10% or 12.5%, and the notice’s product exclusions. The duties apply from 24 July 2026 whoever wins today.

If you send money to Latin America or Africa, cash transfers carry a 1% US tax; bank and card transfers do not. Repeal would need both chambers and the president.

If you follow from Africa or Latin America, first signals arrive after 7 p.m. ET and a fuller picture by Wednesday morning. Treat early projections as estimates until states certify their counts.

Frequently Asked Questions

When do polls close in the US midterm elections?

Polls close from 6 p.m. ET on Tuesday 3 November 2026, with the last at 1 a.m. ET in Alaska’s Aleutian Islands. Hours vary by state.

Who is expected to win the US midterms?

Polymarket gave Democrats a 94.5% chance of the House and 76.5% of the Senate at 4:32 a.m. ET on 3 November. These are bets, not results.

How could the US midterms affect Latin America?

Congress shapes spending, trade reviews and remittance rules, but Section 301 tariffs and deportation policy rest largely with the president. A Democratic House would add hearings, not repeal.

How could the US midterms affect Africa?

Congress decides whether to renew AGOA, which expires on 31 December 2026, and funds aid programmes. Section 301 tariffs of 12.5% on seven African economies are executive.
