Stocks Rally After Democratic Midterm Sweep, With Winners and Losers Split by Sector
US stock markets rose sharply on Wednesday after a wave of Democratic victories in the midterm elections, a result some on Wall Street have nicknamed the "Blunami." Major indexes dipped overnight as results came in, then reversed course and climbed through the trading day. The Dow Jones Industrial Average gained nearly 1,600 points in the session, its best day since April 2025, when President Donald Trump announced a pause on tariffs that set off a lengthy rally.
By the 4:00 p.m. ET close, the Nasdaq 100 had added about 1%, a move some analysts read as a sign that investors do not expect the artificial intelligence trade to face major disruption even as Democrats prepare to hold more power in Congress. Without a veto-proof majority, any new rules around data centers and AI infrastructure are more likely to play out at the state and local level rather than through sweeping federal action.
Still, the results were not uniformly positive. Data center operators and so-called neocloud companies fell on the news. CoreWeave dropped 9%, the Roundhill Neocloud ETF slid 8%, IREN Limited fell 11%, and Nebius dropped 7%. In Texas, a state expected to host around 30% of future US data center capacity through 2030, Democrat Gina Hinojosa's win in the governor's race was viewed as a negative signal for infrastructure developers. Dan Ives, a senior managing director at Yorkville Ives, wrote that Hinojosa's known opposition to data centers raises real questions for tech investors watching the state's buildout. SpaceX dropped as much as 7%, and Tesla, also headquartered in Texas, fell as much as 4%.
Defense stocks also slipped, as investors weighed the possibility that a Democratic-led Congress could push toward a resolution of the ongoing US-Iran conflict, which has weighed on markets through much of 2026.
Investments tied to Trump and his family were among the hardest hit. Trump Media & Technology Group fell 23% by Wednesday afternoon, and the TRUMP cryptocurrency token dropped 17%, along with other related tokens. Art Hogan, chief market strategist at B. Riley Wealth Management, described these as "hyperspeculative" assets that do not trade on clear fundamentals, adding that a Democratic sweep of Congress likely puts more scrutiny on their value as investment vehicles.
On the winning side, healthcare stocks gained as markets priced in a higher chance that Democratic lawmakers will move to reverse some cuts to programs such as Medicaid and Medicare. Hogan noted healthcare shares had already been outperforming in the months leading up to the election. Renewable energy stocks rose as well, on expectations that a Democratic Congress may offer more policy support to the sector.
Treasury yields fell across maturities, and gold and bitcoin both climbed, with gold up nearly 3% to $4,054 an ounce and bitcoin up 3% to around $79,864. Ranim Turfa, head of research and market analysis at Tickmill's Middle East and North Africa arm, said that as markets scale back expectations for further rate hikes, Treasurys and the dollar become less attractive relative to non-yielding assets like gold and crypto, which can draw more money into those markets.
Historically, midterm elections have tended to be followed by stock gains regardless of outcome. According to analysis from BlackRock, the S&P 500 has gained an average of 14% in the six months after a midterm election since 1970, compared with an average 6% gain in years without midterms. Justin Buell, chief investment officer of Continuity Group, wrote that midterms often arrive at a useful moment to settle markets after a stretch of volatility, and that stocks have tended to rally afterward no matter which party wins.
Who this affects
This story touches investors holding positions in AI infrastructure, neocloud, defense, healthcare, renewable energy and crypto-linked assets, as well as anyone watching broader index funds tied to the Dow, S&P 500 or Nasdaq. It may also matter to Texas residents and businesses connected to the data center industry, given the state's outsized role in planned capacity.
