Welcome to Thoughts on the Market. I’m Michael Zezas, Global Head of Fixed Income Research and Public Policy Strategy.

Today, we’re tackling a question that’s top of mind after last week’s off-cycle elections in New Jersey, New York, Virginia, and California: What could next year’s midterm elections mean for investors, especially if Democrats take control of Congress?

It’s Friday, Nov 14th at 10:30am in New York.

In last week's elections, Democrats outperformed expectations. In California, a new redistricting measure could flip several house seats; and in New Jersey and Virginia Democrat candidates, won with meaningfully higher margins than polls suggested was likely. As such prediction markets now give Democrats a roughly 70 percent chance of winning the House next year.

But before we jump to conclusions, let’s pump the brakes. It might not be too early to think about the midterms as a market catalyst. We’ll be doing plenty of that. But we think it's too early to strategize around it. Why? First, a lot can change—both in terms of likely outcomes and the issues driving the electorate. While Democrats are favored today, redistricting, turnout, and evolving voter concerns could reshape the landscape in the months to come.

Second, even if Democrats take control of the House, it may not change the trajectory of the policies that matter most to market pricing. In our view, Republicans already achieved their main legislative goals through the tax and fiscal bill earlier this year. The other market-moving policy shifts this year—think tariffs and regulatory changes—have come through executive action, not legislation. The administration has leaned heavily on executive powers to set trade policy, including the so-called Liberation Day tariffs, and to push regulatory changes.

Future potential moves investors are watching, like additional regulation or targeted stimulus, would likely come the same way. Meanwhile, the plausible Republican legislative agenda—like further tax cuts—would face steep hurdles. Any majority would be slim, and fiscal hawks in the party nearly blocked the last round of cuts due to concerns over spending offsets. Moderates, for their part, are unlikely to tolerate deeper cuts, especially after the contentious debate over Medicaid in the OBBBA (One Big Beautiful Bill Act).

So, what could change this view? If we’re wrong, it’s likely because the economy slows and tips into recession, making fiscal stimulus more politically appealing—consistent with historical patterns. Or, Democrats could win so decisively on economic and affordability issues that the White House considers standalone stimulus measures, like reducing some tariffs.

How does this all connect to markets? For U.S. equities, the current policy mix—industrial incentives, tax cuts, and AI-driven capex—has supported risk assets and driven opportunities in sectors like technology and manufacturing. But it also means that, looking deeper into next year, if growth disappoints, fiscal concerns could emerge as a risk factor challenging the market. There doesn’t appear an obvious political setup to shift policies to deal with elevated U.S. deficits, meaning the burden is on better growth to deal with this issue.
