Washington, United States | November 4, 2026

🔹 What happened?

Following the November 3 midterm elections, in which Democrats gained control of both the House of Representatives and the Senate, flipping more than 50 House seats and securing seven additional Senate seats in states ranging from Kansas to Texas, US stock index futures climbed overnight.

When Wall Street officially opened at 9:30 a.m. New York time, the rally extended to the major indices:

Dow Jones: +1.8%

S&P 500: +1.1%

Nasdaq: +1.0%

📌 What exactly are stock futures?

Stock futures are not shares themselves. They are standardized financial contracts traded through the CME Globex platform, allowing investors to buy or sell the value of a financial index at a future date.

For example:

• E-mini S&P 500 (ES): Each index-point movement represents $50 per contract.

• Nasdaq-100 (NQ): Each index-point movement represents $20 per contract.

Two key characteristics explain their importance:

1️⃣ Nearly continuous trading:

Futures trade almost 24 hours a day, beginning at 6 p.m. Eastern Time on Sunday, allowing markets to absorb and price election results before the regular stock market opens.

This is why CNN highlighted the movement in futures: they provided the earliest indication of the markets’ reaction, rather than a delayed response.

2️⃣ Leverage and investor sentiment:

Futures contracts use leverage, meaning even relatively small price movements can reflect changes in investors’ positions and expectations ahead of the market opening.

📌 Why did markets rise instead of fall?

The picture is not uniform. Market data reveals significant differences between sectors.

▪️ Reduced political uncertainty:

Trump’s public acceptance of the election results lowered political uncertainty, removing part of the risk premium investors had previously priced into the markets.

▪️ Hopes of tariff relief:

Shares of import-dependent retailers advanced amid expectations that some of the tariffs imposed by the Trump administration could be reduced.

• Target: +3.3%

• Walmart: +1.3%

The retail sector generally benefits from lower import tariffs, while Democrats have supported rolling back some of these measures.

▪️ Healthcare sector repricing:

Healthcare and insurance stocks experienced mixed movements as investors anticipated increased Democratic pressure to reduce prescription drug prices and limit insurers’ profit margins.

• CVS: −12%

• UnitedHealth: −2.9%

• Cigna: +1.6%

▪️ Pressure on artificial intelligence stocks:

Nvidia and Oracle opened lower amid concerns that Democratic control of the Senate could obstruct legislation supporting the expansion of AI infrastructure.

Analyst Dan Ives, associated with Wedbush and Yorkville, stated that “10% of datacenters will not happen now,” pointing to the potential consequences of the new political balance for investment in the sector.

▪️ Oil prices declined alongside the stock market rally:

• Brent crude: −3.1% to $100.40

• West Texas Intermediate (WTI): −3.1% to $93.08
