Will Midterm Elections Cause the Trump Bull Market to Crash? History Says There's Good and Bad News...

Prediction-market traders on Oct. 24 put a 66% chance on Democrats retaking both houses of Congress on Nov. 3, with another 26% expecting Republicans to lose the House but retain the Senate. Historical S&P 500 data for 1926–2023 show a 7.33% average annual return under a Republican president with a divided Congress—the lowest of four scenarios cited—but the article says this setup does not raise crash odds and could make tax and spending policy more predictable. Debt-ceiling negotiations and the risk of a prolonged government shutdown are identified as potential headwinds.

Analysis

The election is more likely to change the distribution of policy risk than the earnings outlook by itself. A split Congress could reduce the chance of abrupt tax or spending legislation, benefiting businesses that value regulatory and fiscal stability; that offset may support broad-market multiples even if legislative gridlock headlines increase. The historical return comparison is not a reliable forecast: it does not isolate the effects of interest rates, inflation, valuation, or economic conditions across different political periods.

The more consequential tail is fiscal brinkmanship, but a government shutdown and a debt-ceiling impasse are distinct events with different market transmission. A shutdown can delay federal activity and weigh on contractors or confidence; a debt-ceiling standoff can disrupt Treasury cash management and create acute stress in bills maturing near a potential payment date. The article supplies no deadline or maturity-level detail, so that risk cannot yet be priced from the information provided.

In the next several days, election positioning and headline-driven volatility matter more than the long-run historical averages. Over 1–3 months, control of Congress and funding negotiations are the catalysts. Over 6–18 months, macro conditions and actual changes to spending, taxes, and regulation should dominate any simple party-control effect. Contrarian point: investors may be over-reading the return history while underweighting the possibility that reduced legislative capacity is supportive for policy-sensitive valuations. Conversely, assuming divided government guarantees stability misses the funding-calendar tail risk.

Key Decisions for Investors

• Do not make a broad U.S. equity short solely on the historical divided-government return figure. Keep core exposure tied to earnings and macro signals; reassess after the result rather than treating prediction-market odds as a certain outcome.
• Ahead of Nov. 3, consider a limited, defined-risk VIX call spread only if election-week implied volatility is not already expensive versus realized volatility. This is an event hedge, not a directional market thesis; reduce or close it promptly if volatility fails to rise after the result.
• Put Treasury-bill maturity dates and any announced debt-ceiling or funding timeline on the watchlist. If a specific payment-risk window emerges, avoid concentrated exposure in bills maturing inside it and compare affected bill yields with nearby maturities before trading; no such window is established by the article.
• Falsify the stability thesis if post-election funding negotiations produce a credible near-term payment disruption, or if policy announcements materially change fiscal projections. Falsify the volatility-hedge thesis if election uncertainty resolves without a sustained rise in implied or realized volatility.
