James Picerno: US Divided Government Lowers Policy Uncertainty, Boosting Stocks, but AI Data Center Sector Already Under Pressure

In an analysis following the 2026 US midterm elections, James Picerno argues that a divided government, with Democrats controlling Congress and Republicans holding the White House, supports equity markets through two channels: reduced policy uncertainty and constrained deficit expansion. However, regulatory risks for AI data centers are already priced into relevant ETFs, and the President retains unilateral authority over tariffs and foreign policy.

The results of the United States midterm elections have created a unique political landscape in Washington, D.C.: a Republican president alongside a Democratic-controlled Congress. James Picerno, author of The Capital Spectator, argues that this divided government is not a negative factor for the market; rather, it provides new support logic for asset pricing through two distinct channels.

The first channel is policy predictability. A divided government means that tax code revisions, large-scale deregulation, or expansive fiscal stimulus face significant hurdles in Congress. Picerno points out that reducing policy surprises itself provides businesses and investors with a more stable operating environment, a level of certainty that markets have historically preferred.

The second channel is fiscal discipline. Picerno contends that the combination of a Democratic-controlled Congress and a Republican White House makes it harder to pass legislation that significantly expands the budget deficit. While this gridlock is unlikely to reverse the long-term upward trend of federal debt, it lowers the probability of new, large-scale fiscal stimulus. A verifiable anchor for this judgment is the yield on the 10-year U.S. Treasury note: if yields stabilize or decline post-election, it may indicate that bond market investors recognize divided government as an effective constraint on deficit expansion; if yields continue to rise, it suggests investors remain concerned that the trajectory of federal debt will not change regardless of which party controls Congress. Picerno notes that the 10-year yield has recently fallen back below 5%, implying that the market is temporarily less worried about inflation and fiscal risk.

However, Picerno simultaneously identifies a sectoral exception: AI data center infrastructure. Citing a poll released by Politico last week, he notes that approximately half of Americans oppose building data centers within a few miles of their homes, a figure that has risen sharply from 28% in January. As public sentiment shifts toward supporting restrictions, Democrats may seek stricter regulation of data center development. The market appears to be pricing in this possibility: two ETFs serving as proxies for data center and digital infrastructure stocks have fallen sharply in recent weeks, while the S&P 500 ETF (SPY) has remained largely flat. This implies that the transmission mechanism of divided government to the AI infrastructure sector is opposite to its effect on the broader stock market—policy predictability benefits the broad market, but expectations of tighter regulation weigh on specific sectors.

Picerno’s analysis also leaves open two risk channels still under the President’s unilateral control. First is tariffs: even with a divided Congress, the President can impose or raise tariffs through executive action and existing trade laws, limiting Congress’s ability to restrain such moves. Second is geopolitics: some analysts argue that a lame-duck president may feel fewer constraints in pursuing a more aggressive foreign policy agenda, including a tougher stance toward Iran. Any escalation in tensions could disrupt oil supplies, push up energy prices, and further complicate the inflation outlook. Currently, the U.S. benchmark crude oil, West Texas Intermediate (WTI), is trading below $100 per barrel. Picerno poses the question: does this reflect a durable easing of geopolitical concerns, or merely a temporary pause before markets reassess the risks of renewed tensions in the Middle East?

Overall, Picerno’s framework breaks down post-election market judgments into testable propositions: bond yields test whether fiscal constraints are being priced in, sector ETF performance tests whether regulatory risks are reflected, and oil prices test whether geopolitical premiums have dissipated. Each has a clear signal direction, allowing investors to track developments continuously without waiting for retrospective summaries.

The core limitation of this analysis lies in causal attribution. The drop in ETFs and the decline in yields may partially reflect pre-election expectation adjustments rather than new information from the election results themselves. The Politico poll shows changes in public sentiment, but translating sentiment into actual legislation or regulatory action takes time and involves uncertainty. The President’s executive power constitutes a clear exception to the constraints of divided government. Picerno’s framework is better suited as an observation list rather than a trading signal.
