The midterms and beyond: How the election may impact the 2027 investment outlook

As the midterm elections approach, investors are considering what a change in Washington could mean for their portfolios. We believe the answer depends not just on who wins, but on what the next Congress can realistically accomplish. Even if Democrats win both chambers, Senate rules and the president’s veto power would still constrain major legislation.

Beyond lawmaking, stronger congressional oversight and greater leverage in fiscal negotiations may still have meaningful consequences for businesses. For investors, that makes it important to look past the initial market reaction and consider where policy could make a more meaningful difference.

Senate control is the greatest source of uncertainty

A Democratic House has become the general consensus expectation, leaving Senate control as the main source of election-night uncertainty. While some projections include Democratic control of both chambers, we remain cautious about the Senate given the Republican-leaning states Democrats would need to win.

A Democratic Congress would control committee agendas and investigations, increasing pressure on the administration and regulated industries. A Democratic House and Republican Senate would produce clearer gridlock, with more House oversight, but a Senate that’s able to block Democratic legislation and continue confirming administration nominees.

If Republicans retain both chambers, another tax-and-spending package becomes possible, although narrow majorities and deficit concerns would likely limit its scope. Maintaining Republican control could also increase medium-term fiscal concerns if additional tax relief or spending comes without meaningful offsets.

Healthcare could become central to a fiscal agreement

We expect federal borrowing to reach the debt ceiling—the limit on government borrowing—around the first quarter of 2027. The U.S. Treasury Department could then use available cash and temporary measures to continue meeting its obligations, with the deadline for congressional action potentially arriving in the fourth quarter of 2027, though precise timing remains uncertain. Once the new Congress is seated, Democratic control of either chamber would prevent Republicans from raising the limit on their own.

That creates a possible opening for healthcare negotiations. Democrats could seek a delay or partial rollback of Medicaid reductions as the price of supporting an increase in the borrowing limit. Scheduled restrictions on how states finance Medicaid and pay providers begin tightening in late 2027 and early 2028, close to the expected negotiations.

We believe provider funding is a more plausible negotiating target than Medicaid work requirements or enhanced Affordable Care Act subsidies. Pressure on rural hospitals from Medicaid reductions could create common ground with Republican lawmakers. A temporary postponement of the scheduled restrictions on state Medicaid financing and provider payments, rather than outright repeal, may be the most achievable compromise.

Estimates suggest approximately $200 billion of Medicaid relief over multiple years could be politically achievable.ⁱ A temporary fix could also prove more expensive over time if Congress repeatedly extends it.

Medicaid-dependent hospitals would be the clearest beneficiaries, with potential relief for their margins. Managed-care companies could receive indirect support from more stable program funding, but risks involving payment levels, demand for care and eligibility rules are already materializing, including enrollment declines from work requirements taking effect in early 2027. A lasting market response would depend on the substance of negotiations rather than the election result.

More scrutiny does not necessarily mean new restrictions

For banks, a Republican Senate hold would likely be the more supportive near-term result. A Democratic Congress could bring more hearings and investigations focused on regulation, fees, consumer finance and mergers. Yet agencies would continue to implement banking rules under the Republican administration, so we believe the initial market reaction could overshoot the immediate change in policy fundamentals.

AI and data-center development face a similar distinction. A Democratic Congress would likely intensify scrutiny of electricity demand, utility bills, environmental permitting and competition. Major federal restrictions would still face substantial barriers; the more practical risks involve project costs, delays and local opposition. Notably, a bipartisan Senate permitting agreement unveiled in late September would ease environmental review timelines and transmission siting for all energy projects—a reminder that legislative dynamics on infrastructure cross party lines in both directions.

Projects with secured power, progress toward grid connections and constructive local relationships should be better positioned than those dependent on future capacity. We see greater risk to the cost and timing of development than to the overall AI investment cycle.

Earnings remain the most durable guide

Historical political comparisons offer limited guidance. Equities have generally performed better under divided government, but a Republican White House with a Democratic Congress has been among the weaker combinations.ⁱⁱ These comparisons rely on small samples, examine only one variable and show correlation rather than causation. They are not forecasts, and they do not change our positive outlook for U.S. equities, which have been supported by impressive earnings growth for the last several quarters. We believe that will remain the case in coming quarters as well.

For investors, the priority is to distinguish political headlines from changes in business fundamentals. In equities and credit, that means assessing sector-specific opportunities and how policies are implemented. In bonds, it means watching Treasury-market liquidity and the additional yield investors demand for longer-term uncertainty, rather than assuming the election influences the path of monetary policy. Consequential developments will continue to follow well after election night, as the balance of power in policy negotiations will likely change in 2027.
