U.S. stocks plunged on November 5, 2026, as investors reassessed the outlook for artificial intelligence following Democratic victories in the U.S. midterm elections. The Nasdaq Composite fell 5.52%, the S&P 500 dropped 4.36%, and the Dow Jones Industrial Average declined 3.44%.

A major concern is the possibility of tighter restrictions on AI data center construction, including a proposed Democratic-backed bill that would temporarily halt new projects.

The selloff also comes at a critical moment for Anthropic. The Claude developer is preparing for a potentially historic IPO, but growing regulatory uncertainty, weaker technology stocks and valuation concerns have raised questions about its November listing plans.

Key Takeaways

U.S. stock market crash: The Nasdaq fell 5.52% on November 5, while semiconductor stocks suffered particularly heavy losses.
Democrats' AI proposal: The Artificial Intelligence Data Center Moratorium Act seeks to pause new data center construction until federal AI safeguards are established. It has not become law.
Anthropic IPO uncertainty: Potential investors are questioning the timing and valuation of Anthropic's planned November debut.
MEXC market access: Traders can monitor Anthropic's pre-IPO valuation through ANTHROPICUSDT futures and explore event-based opportunities through MEXC Prediction Markets.

Why Did the Nasdaq Fall More Than 5% on November 5?

The technology-led selloff reflected growing concerns that tighter AI regulations could slow the infrastructure investment supporting the industry's rapid expansion.

Following the November 3 midterm elections, investors began reassessing how Democratic control of Congress and changes in state leadership could affect AI development. Restrictions on new data centers could delay demand for semiconductors, memory chips, electricity infrastructure and cloud computing capacity.

According to Reuters, fears of increased AI scrutiny contributed to the market decline.

The Philadelphia Semiconductor Index dropped approximately 12.2%, while Nvidia shares lost more than 9%. Weak semiconductor earnings and broader doubts about the returns on AI investment also contributed to selling pressure.

The market reaction highlights a growing concern: AI companies may continue expanding rapidly, but the infrastructure required to support that growth is becoming more politically and financially uncertain.

What Is the Democrats' AI Data Center Moratorium Act?

The Artificial Intelligence Data Center Moratorium Act (H.R. 9442) was introduced on June 24, 2026, by Democratic Representative Alexandria Ocasio-Cortez and several Democratic co-sponsors.

The proposal would temporarily restrict the construction of new AI data centers until federal legislation establishes safeguards addressing AI risks and their effects on communities.

The underlying concerns include rising electricity costs, environmental impacts, resource consumption and public oversight of AI infrastructure.

Importantly, the bill is not law. It remains a legislative proposal, and its future is uncertain. Any federal restrictions would require further legislative action and would face potential opposition from the Trump administration.

However, state and local authorities may independently introduce stricter permitting requirements, construction pauses or additional utility-cost protections.

For AI investors, the immediate question is not whether AI development will stop, but whether infrastructure costs and project timelines could change significantly.

Could the AI Selloff Delay Anthropic's IPO?

Anthropic's planned IPO is emerging as an important test of investor confidence in the AI sector.

The company filed updated IPO documents on November 2, reporting approximately $17 billion in third-quarter revenue, up 47% from the previous quarter. However, its disclosures also highlighted roughly $895 billion in computing and infrastructure commitments.

According to Reuters, potential investors are questioning whether Anthropic can proceed with its expected roadshow during the week of November 9 and complete its listing later in November.

Some investors reportedly consider the discussed $1.5 trillion valuation too high under current market conditions and are seeking a more attractive offering price.

The proposed restrictions on data centers add another layer of uncertainty. Anthropic relies on extensive computing infrastructure to train and operate its AI models. Higher development costs, delayed capacity or more expensive financing could affect its future growth economics.

This does not mean Anthropic's IPO will necessarily be postponed. However, the combination of regulatory uncertainty, large infrastructure commitments and falling technology valuations could complicate the company's pricing discussions.

How Can Traders Follow Anthropic IPO Uncertainty on MEXC?

With Anthropic still privately held, investors cannot yet buy its publicly listed ANT shares.

However, MEXC offers ANTHROPICUSDT pre-IPO perpetual futures, allowing eligible traders to take long or short positions based on the market's assessment of Anthropic's valuation before its public listing.

These derivatives do not represent ownership of Anthropic shares, and leveraged trading carries substantial risk.

MEXC also offers Prediction Markets, where eligible users can explore event-based markets, subject to available contracts and regional restrictions.

For Anthropic, the questions worth monitoring include whether the IPO proceeds in November, whether its offering valuation changes and whether proposed AI infrastructure restrictions advance.
