Global stocks and US Treasuries rose on Wednesday as investors assessed a historic Democratic sweep in the midterm elections. Markets appeared to bet that divided government would constrain major policy shifts and reduce the chance of worst-case outcomes, including an escalation of the Iran war.
All three major Wall Street indexes traded higher. Treasury yields fell, with investors anticipating tighter oversight of fiscal policy and less room for increased government spending. Oil also dropped, adding to expectations that inflationary pressure could ease if the decline continues.
The election results have shifted expectations around the AI industry. Investors had worried that a Democratic-controlled Congress would increase scrutiny of data centers and slow construction. On Wednesday, shares of Amazon, Meta Platforms and Alphabet rose, while several data center operators fell. chip stocks also declined, with the PHLX Semiconductor Sector Index down 3.6%.
Some investors said a slower pace of data center investment could address concerns about the borrowing costs of the buildout. Strategists at Jefferies said Democratic gubernatorial victories in five states with data center exposure could lead to safeguards rather than outright bans, potentially limiting disruption to the AI sector.
The political shift could have differing effects across industries. Managed-care companies and hospitals may benefit if lawmakers support extending Affordable Care Act subsidies, while parts of the financial, defense and crypto sectors could face less favorable conditions if expectations for deregulation or policy support fade. One strategist cautioned against making aggressive sector bets based solely on the election result.
The results also raised questions about the Iran war. Vice President JD Vance distanced himself from President Donald Trump’s decision to enter the conflict after the Republican electoral defeat, and some investors said markets may be beginning to price in de-escalation.
Fiscal uncertainty remains. US debt has recently exceeded $40 trillion, and investors have been watching the impact of borrowing on bond yields. Divided government could restrain spending, but it also raises the possibility of funding disputes and shutdowns. Congress has postponed debate over fiscal 2027 spending until after the midterms, with a December 11 deadline to agree on funding.
Investors also face uncertainty over executive actions, geopolitical risks and AI policy. The election’s initial market reaction was positive, but it has not removed concerns about future spending fights or the political outlook.
