US midterms 2026: Why corporate America is bracing for a Democratic Congress

Corporate America is watching the US midterm elections for reasons that go beyond the battle for control of Congress. A Democratic victory could bring some of the country’s biggest companies under greater scrutiny, with technology giants, private equity firms, banks and artificial intelligence (AI) developers facing the prospect of congressional investigations and hearings.

The stakes are particularly high for Silicon Valley. Several prominent technology executives have cultivated closer relationships with President Donald Trump since his return to the White House in January 2025. If Democrats regain control of the House of Representatives or the Senate, those relationships could become a subject of congressional scrutiny.

But the potential shift in Washington goes beyond corporate ties with the president. Democrats are increasingly connecting the rapid expansion of AI, the construction of energy-intensive data centres and the growing influence of private equity to a concern central to the election: the rising cost of living in America.

With voters heading to the polls on November 3, the midterms could determine how aggressively Congress examines the industries driving America’s next phase of economic growth.

Why Silicon Valley is preparing for a political backlash

The technology industry has a particular reason to watch the election. Its relationship with Trump has changed considerably since he returned to the White House.

Some of the biggest names in technology have sought closer engagement with the Republican administration. Executives including Meta CEO Mark Zuckerberg, Amazon founder Jeff Bezos, Google CEO Sundar Pichai, Apple CEO Tim Cook and Tesla CEO Elon Musk have all appeared alongside or engaged with Trump.

The relationship has partly reflected the industry’s interest in a business environment that favours rapid AI development, fewer regulatory restrictions and greater investment in technology infrastructure.

But the political calculation could become more complicated if Democrats regain control of Congress.

A Washington Post report published on October 26 said technology and defence companies were preparing for the possibility of a Democratic Congress. Some firms had approached Democratic strategists about political engagement, potential donations and board appointments as they assessed the possibility of a change in congressional leadership.

Companies including Palantir, OpenAI and Meta have attracted criticism from Democratic lawmakers over their activities and relationships with the Trump administration. Defence technology companies with government contracts and links to the president’s family have also emerged as potential subjects of scrutiny.

The questions could extend to whether companies received favourable treatment from the administration, how government contracts were awarded and whether political relationships influenced business decisions.

Democratic lawmakers have already sought information about companies linked to the Trump family and their government dealings. A change in congressional control could give them greater powers to pursue such inquiries.

This is because congressional committees can use their oversight powers to request documents, summon executives and hold public hearings. Committee leadership also influences which investigations receive attention and resources.

For companies, even an investigation that does not result in penalties or legal action can create difficulties. Hearings can generate negative publicity, increase legal and compliance costs and put pressure on relationships with government agencies and investors.

The Washington Post report quoted Brandon Rios, co-leader of the congressional investigations team at law firm DLA Piper, as saying companies in the technology and defence ecosystem could face investigations on multiple fronts.

AI could become the biggest technology battleground

Artificial intelligence is emerging as one of the most important issues in the election and potentially one of the biggest areas of conflict between technology companies and Democratic lawmakers.

Trump has backed rapid AI development and argued that the US must maintain its lead over China. His administration has generally favoured fewer regulatory restrictions to allow companies to develop and deploy AI systems.

Democrats, meanwhile, are increasingly focusing on the economic and social consequences of the technology.

The concerns extend beyond the possibility of AI replacing jobs. They include the use of AI in hiring and housing decisions, surveillance, consumer pricing, children’s safety, election misinformation and the risks posed by increasingly powerful AI models.

If Democrats gain control of congressional committees, they could seek more information from technology companies about how their AI systems are developed, tested and deployed.

There are already signs of this approach.

On October 28, Democratic leaders on the House Judiciary and Energy and Commerce committees asked five leading AI companies to report serious incidents involving model misalignment and safety within 48 hours of detecting them.

The lawmakers raised concerns about reports of AI models taking unintended or potentially unsafe actions during testing. Their requests focused on the ability of companies to identify, monitor and report such incidents.

This is significant because the debate over AI safety is moving beyond broad warnings about the technology’s future. Lawmakers are increasingly asking companies to explain what happens when their systems behave in unexpected ways and what safeguards are in place to prevent harm.

Election misinformation is another area attracting attention.

On October 20, senior Democratic lawmakers urged 25 technology companies, including Alphabet, Meta, Microsoft, OpenAI and TikTok, to strengthen safeguards against deceptive AI-generated content and false voting information ahead of the midterms.

They raised concerns about foreign influence campaigns, manipulated media and the ability of AI-generated images, videos and audio to mislead voters.

The issue is particularly important because technology platforms have become major channels through which Americans receive political information. The spread of fabricated content can create confusion about candidates, voting procedures and election results.

Democratic lawmakers have also pressed Google, Meta, TikTok and X to enforce their own policies against misleading information about mail-in voting.

This, for technology companies, creates a difficult balancing act. They want to develop increasingly powerful AI systems while avoiding rules that could slow innovation or increase their liability. But the growing political focus on AI means companies may have to provide greater transparency about the risks associated with their products.

Data centres bring the AI debate into American homes

The controversy surrounding AI is no longer limited to technology companies, regulators and researchers. It is increasingly affecting local communities.

The rapid expansion of data centres has raised concerns about electricity consumption, water availability, infrastructure costs and the tax incentives offered to companies building these facilities.

Data centres provide the computing capacity needed to train and operate AI models. As technology companies expand their AI businesses, demand for these facilities is increasing.

But their expansion also raises a difficult question for local communities. Who pays for the additional electricity generation, transmission lines and other infrastructure required to support them?

If utilities need to invest in new infrastructure to meet rising demand, some of those costs could eventually be passed on to households and smaller businesses through higher electricity bills.

This has become a politically sensitive issue in states where large data centre projects are being developed.

A September 30 vote in the US Senate highlighted the disagreement over how to address the problem. A bill sponsored by Republican Senator Jon Husted of Ohio, which sought to make large electricity users account for the costs of grid upgrades, failed to advance after receiving 57 votes, short of the 60 needed.

The House had previously passed the measure by 417 votes to three. However, Senate Democrats opposed it, arguing that its provisions were not strong enough because they left important requirements to regulators’ discretion.

The episode showed that concerns about data centre electricity costs are not limited to Democrats. Lawmakers from both parties recognise that the expansion of AI infrastructure is becoming a voter issue, although they disagree on how companies should pay for it.

Democrats have also begun questioning the tax benefits available to technology companies expanding their data centre operations.

On October 14, Senate Finance Committee ranking member Ron Wyden, along with Elizabeth Warren and other Democratic senators, questioned Meta’s use of federal research and development tax credits for its AI data centre expansion.

The lawmakers pointed to an increase in Meta’s reported research and development tax credits from $700 million in 2023 to $4 billion in 2025. They asked the company to explain whether expenses associated with building and operating AI data centres qualified for credits intended to encourage experimental research.

The questions do not establish that Meta misused the tax credits. The company was asked to provide its explanation and the legal basis for its claims.

Wyden has separately proposed changes to the tax treatment of data centres, including removing certain investment incentives and exploring ways to raise revenue to support communities and workers affected by AI-related economic disruption.

If Democrats gain control of the Senate, Wyden could take over the powerful Senate Finance Committee, giving him greater influence over investigations into corporate taxation.

For technology companies, the implications could be significant. The economics of AI infrastructure depend not only on demand for computing power but also on electricity, land, construction, financing and government incentives.

Changes to tax treatment or electricity regulations could affect the cost of building new data centres and the profitability of projects that underpin the AI investment boom.

Why private equity and Wall Street could also face scrutiny

The potential investigations are not confined to technology companies.

Private equity firms and financial institutions could also face greater congressional scrutiny, particularly as Democrats look for ways to connect corporate financial practices with the cost of living.

Private equity firms raise money from investors, acquire businesses and seek to increase their value before selling them or taking them public. Their investments span healthcare, housing, infrastructure, technology and other sectors.

Democratic lawmakers have increasingly questioned whether some private equity ownership structures and financial practices contribute to higher costs for consumers.

Healthcare is a particular area of concern. Private equity investments in hospitals, medical practices and other healthcare businesses have attracted scrutiny over debt, staffing, service quality and the financial sustainability of providers.

Housing is another potential area of investigation, given the growing role of institutional investors in residential property markets.

The broader question is whether financial structures that benefit investors also create additional costs for consumers or affect access to essential services.

The issue could become a priority if Senator Ron Wyden takes over the Senate Finance Committee following a Democratic victory.

Daniel Goshorn, chief investigative counsel for the Democratic side of the Senate Finance Committee, told Reuters on October 29 that private equity was a major focus for several Democratic senators.

He specifically pointed to how private equity’s financial structures could affect healthcare costs, housing and other essentials.

Goshorn also indicated that banks could be asked to provide information if the Trump administration does not cooperate with congressional oversight requests.

Corporate money is also shaping the midterm battle

There is an irony in the election. While some companies are preparing for the possibility of greater scrutiny under a Democratic Congress, wealthy business leaders and technology executives are also spending heavily to influence the political contest.

Elon Musk has emerged as one of the biggest political donors in the 2026 election cycle.

According to an Associated Press report, Musk has contributed more than $276 million since July to support Republican efforts to retain control of Congress. His contributions include $158 million to the Senate Leadership Fund, the main super PAC supporting Republican Senate candidates, and $76 million to his own America PAC.

His spending highlights the role wealthy individuals and business interests are playing in the battle for congressional control.

The wider fundraising picture is equally significant.

A Brennan Center for Justice analysis published on October 27 found that the 40 biggest donors in this year’s midterm elections had contributed nearly $2.5 billion through mid-October. This was a record for this point in a midterm election cycle since the Supreme Court’s 2010 Citizens United decision.

Can a Democratic Congress actually change the rules?

A Democratic victory would not automatically translate into tougher laws for technology companies, private equity firms or banks.

The distinction between congressional investigations and legislation is important.

If Democrats regain control of either chamber, they could chair committees, set investigative priorities, summon corporate executives for hearings and seek documents through congressional oversight.

A Democratic majority in both chambers would give the party greater influence over the legislative agenda.

But passing new legislation would be more difficult.

Trump would remain president and retain the power to veto bills passed by Congress. Democrats would also need sufficient support in the Senate to overcome procedural hurdles and advance major legislation.

This means investigations could move faster than regulatory changes.

Companies could face congressional hearings and requests for information even if lawmakers are unable to pass new AI safety laws or major changes to corporate taxation.

There is also no guarantee that Democrats will agree on a common approach to AI regulation. Some lawmakers may favour tougher restrictions on technology companies, while others could be more concerned about maintaining America’s competitive position against China.

Republicans, too, are not uniformly opposed to greater oversight. The bipartisan concerns surrounding data centre electricity costs show that some issues could attract cooperation across party lines.

What the US midterms mean for businesses and investors

The November 3 elections will determine all 435 seats in the House of Representatives and 35 of the 100 seats in the Senate, including two special elections.

Democrats need to make gains to take control of Congress. While the party has a path to winning the House, the Senate contest remains closely fought.

The result will determine how much influence Democrats have over congressional investigations, government spending and the legislative agenda during the remaining two years of Trump’s presidency.

For corporate America, the implications could extend well beyond Washington.

Technology companies could face greater scrutiny over AI safety, election misinformation, political relationships and data centre investments. Private equity firms could be asked to explain how their ownership structures affect healthcare, housing and other essential services. Banks could receive information requests linked to investigations into government decisions and corporate dealings.

The consequences could also reach investors. Greater scrutiny, uncertainty over tax incentives and the possibility of new compliance requirements could affect business plans, investment decisions and valuations in sectors that have benefited from the administration’s approach.

But there is another side to the debate.

The US is investing heavily in artificial intelligence, semiconductor infrastructure and data centres. These investments are central to America’s ambition to maintain its technological lead over China.

Regulatory changes that significantly increase the cost of developing AI infrastructure could affect the pace of investment. At the same time, failing to address electricity costs, employment disruption and consumer concerns could deepen public opposition to the technology.

That is the challenge facing policymakers.
