How will the 2026 midterm elections impact the U.S. stock market and the crypto market? An in-depth analysis

November 3, 2026, the United States will hold midterm elections. All 435 seats in the House of Representatives, about one-third of Senate seats, and 39 governor seats will be up for election. This election is not only about the redistribution of domestic political power in the U.S., but will also affect how global financial markets operate across multiple dimensions—from sector rotation and volatility characteristics in the U.S. stock market, to regulatory expectations and capital flows in the cryptocurrency market.

What is the most likely congressional configuration after the midterm elections?

Based on current election conditions and historical experience, the most likely scenario for the 2026 midterm elections is Republicans losing control of the House while retaining control of the Senate. President Trump’s current approval rating has already reached a historic low, and historical data shows that the ruling party generally loses a larger number of House seats in midterm elections. Stifel’s early predictions also point to the House possibly shifting to Democratic control, while the Senate maintains a Republican majority.

However, redistricting has allowed Republicans to gain a net 8 seats in the House, so there is still some possibility that Republicans could maintain control of both chambers. Regardless of the final outcome, this midterm election may become an accelerator for further polarization in U.S. politics. In the party primaries, Trump has put consolidating his authority within the party as the top priority, and multiple internal dissenters have been defeated by his supporters.

How different election outcomes could reshape policy directions

Under the most likely scenario of “the House turning blue and the Senate staying red,” Trump’s domestic policy agenda will face constraints from Democrats in the House. Faced with legislative gridlock, the executive branch will rely more on executive orders, regulatory policies, and emergency measures to advance its agenda. Democrats, meanwhile, may concentrate their efforts on investigative power, subpoena power, budgetary leverage, and hearing arrangements—continuously draining the White House of political capital.

If Democrats unexpectedly control both chambers, Trump’s policy agenda will be difficult to carry out, and his authority within the party could be damaged. Conversely, if Republicans retain control of both chambers, the current policy direction is likely to continue.

It is worth noting that even if control of Congress changes, the actual changes in policy actions may be more limited than the market expects. Stifel points out that, so far, the number of transformative laws passed by a Republican-controlled Congress has not been large. Most policy actions come from the executive level, and even if the House changes hands, this situation is unlikely to change significantly.

What historical patterns does the U.S. stock market show in midterm election years?

Based on historical data, in midterm election years the U.S. stock market often exhibits a specific volatility pattern. Canaccord Genuity’s data shows that in the second and third quarters of midterm election years, the S&P 500 index averages a decline of 3.87%, while the Russell 2000 index’s average drop is even larger at 9.12%. However, after midterm elections end, markets often rebound strongly. The S&P 500’s average return 12 months after the midterms is 19%, and since 1939 it has never recorded a negative annual return.

The core logic behind this pattern of “pressure before the election, rebound after the election” is the elimination of political uncertainty. Once the election results are finalized, markets can refocus on more certain factors such as economic fundamentals and corporate earnings.

What election-related risks does the current U.S. stock market face?

The particularity of 2026 is that AI-related stocks currently account for as much as 39% of the weight in the S&P 500 index, reaching the historical ceiling for bubble concentration. This extreme level of concentration has been likened by Bank of America’s chief investment strategist to the railroad stock bubble of the 1980s. Bank of America warns that what can truly cool this kind of market is the rebound strength from voter turnout and the bond market.

The AI industry could become the focal point of election games. Raymond James’s Washington policy analyst notes that Democrats may push for pauses or restrictions on data center operations, and adopt a tougher stance on semiconductor export controls toward China. Given that Nvidia’s market capitalization has exceeded $5 trillion, the policy direction for semiconductors will directly affect the performance of the largest market-cap segment in the U.S. stock market.

In addition, macro factors such as the evolution of the U.S.-Iran conflict, the inflation trajectory, and GDP growth may influence markets far more than the election results themselves. Morgan Stanley’s head of U.S. public policy research believes that the real macroeconomic impact of this midterm election may be smaller than the market imagines—tariff, geopolitical, and deregulation policy vectors are likely to keep driving markets.

Where does cryptocurrency regulation stand during the election cycle?

The fate of cryptocurrency regulation is deeply intertwined with the 2026 midterm elections. The “Crypto Market Structure Clarity Act” (CLARITY Act) being advanced in Congress aims to clarify the regulatory boundary between the SEC and the CFTC, and to establish a comprehensive regulatory framework for the digital asset market. The bill passed the House in July 2025 and was advanced by the Senate Banking Committee in May 2026.

However, as the election cycle approaches, the legislative window keeps narrowing. Galaxy Digital has lowered the probability of the CLARITY Act passing in 2026 from 75% to 60%, citing a reduced Senate schedule and lack of progress on controversies such as ethics and illegal finance. At the same time, prediction markets such as Polymarket show the probability of the bill passing in 2026 has risen to 72%, while Kalshi’s regulated contract trading is approaching 74%. This divergence in probabilities itself reflects the high uncertainty in the market about how election outcomes may influence regulatory direction.

TD Cowen’s Washington research team notes that, under the influence of the election cycle, uncertainty about progress at the Senate level is rising, and core crypto legislation may be pushed to 2027. Tether’s head of government relations also says the midterm elections will be a key litmus test for whether pro-digital-asset policies in Washington can survive politically in the near term.

How does funding in the cryptocurrency industry affect the election landscape?

The cryptocurrency industry is directly stepping into the 2026 election cycle through political donations. Fairshake and its Democratic branch Protect Progress—funded by crypto giants such as Coinbase, Ripple, and Andreessen Horowitz—are pouring large sums into candidates across multiple key districts. The organization has contributed more than $4.9 million to support Black candidates who are favorable to cryptocurrencies. a16z partner Chris Dixon previously announced an additional donation of more than $23 million during the 2026 midterm election cycle.

The double significance of this flow of funds is that, on one hand, it reflects the crypto industry’s strategic investment in shaping the policy environment; on the other hand, election outcomes will determine whether these investments can translate into favorable regulatory frameworks. What the crypto industry faces is no longer short-term policy volatility, but deeper institutional uncertainty. The path toward regulatory clarity could be interrupted before it has truly even unfolded.

Why do search interest rebound and capital outflows happen at the same time?

In June 2026, Google searches for cryptocurrencies showed a clear rebound. Search volumes for tokens such as Bitcoin, XRP, and Solana rose significantly. Global Bitcoin search interest reached a 12-month high in the first week of February 2026, hitting the maximum value of 100 on Google Trends’ relative scale. The rebound in June is seen as an early sign that retail investors are once again paying attention to the crypto market.

However, capital inflows have not risen in sync with the surge in search interest. Since mid-May, the crypto market has experienced large-scale capital outflows. As of June 22, 2026, Bitcoin’s trading price has been oscillating in the $63,600–$64,100 range. In the past 30 days, the total capital flows of stablecoins, spot Bitcoin ETFs, and other products have turned to net outflows, totaling $8 billion. U.S. spot Bitcoin ETFs recorded net outflows of $6.35 billion in 30 days, the largest level since these products launched in January 2024.

An increase in search volume by itself does not mean retail capital is returning. Google Trends spikes can occur during euphoric bull markets, but they can also happen during panic selling or when market uncertainty increases. Search activity reflects attention more than buying power. It shows that retail investors are re-engaging with the market, but it cannot prove that they are buying.

This phenomenon of “search volume rising but money not coming in” reveals a deeper structural problem in the current crypto market: the recovery in attention has not translated into actual buying behavior. On-chain data indicates that small holders are still reducing positions as search volume climbs, while large addresses are accumulating. The key takeaway from this pattern is that a rise in attention does not automatically equate to new capital inflows.

Summary

The impact of the 2026 U.S. midterm elections on the U.S. stock market and the cryptocurrency market is not simply a binary judgment of “positive” or “negative.” Instead, it is a combined effect of a series of structural variables across different time horizons.

For the U.S. stock market, historical patterns point to increased volatility before the election and a rebound afterward. But the special feature of 2026 is that the extreme concentration in the AI sector has significantly increased the market’s sensitivity to policy changes. Election topics such as semiconductor controls and data center regulation could directly hit the sectors with the largest market capitalizations.

For the cryptocurrency market, the election’s impact is more about institutional uncertainty in the regulatory path. The legislative fate of the CLARITY Act, changes in the balance of power in Congress, and the return cycle of political donations in the crypto industry will become clearer step by step after Election Day. Meanwhile, the divergence between the rise in search interest and capital outflows reflects retail investors’ watch-and-wait stance under the pressure of both macro uncertainty and unclear regulatory prospects.

Ultimately, whether for the U.S. stock market or the cryptocurrency market, the real effect of the election may not lie in who wins, but in when uncertainty is resolved—and how the market reprices afterward.
