What Prediction Markets Are Forecasting

Prediction markets currently give roughly a 1 in 20 chance that President Trump or Congress will eliminate federal income taxes for people earning under $150,000 before 2027. In simpler terms, traders collectively see this as very unlikely to happen. The market reflects a high degree of skepticism, with only a small fraction of bets supporting the idea.

Why the Market Sees It This Way

The low probability stems from significant political and practical hurdles. First, completely eliminating a major revenue source like the income tax for a large segment of taxpayers would create a massive budget deficit. The federal government collected over $2 trillion from individual income taxes in 2023. Removing that for most earners would require unprecedented spending cuts or other tax increases that lack political support.

Second, such a change would almost certainly need to pass Congress. Even if President Trump proposed it, the legislative process requires building a majority coalition. Given the current divided Congress and the historic difficulty of passing major tax reforms, the path to a law is extremely narrow. An executive order alone is viewed as an insufficient tool for this policy, as tax law is fundamentally controlled by Congress.

Finally, the proposal does not align with recent tax policy trends. The 2017 Tax Cuts and Jobs Act, passed under Trump, reduced rates but kept the income tax structure intact. Major policy discussions have focused on adjusting rates and brackets, not eliminating the tax entirely for most Americans.

Key Dates and Events to Watch

The primary timeline to watch is the next presidential term, from January 2025 through 2026. Key moments include the release of the President’s first budget proposal in early 2025, which would signal administration priorities. Any major tax legislation would likely need to be introduced and debated in 2025 or early 2026 to pass before the 2026 midterm elections, which could shift the balance of power in Congress. Committee hearings in the House Ways and Means Committee and the Senate Finance Committee would be early indicators of serious legislative effort.

How Reliable Are These Predictions?

Prediction markets have a mixed but generally decent record on political process questions. They are often good at identifying high-stakes legislative hurdles and the low probability of extremely disruptive policy changes. However, they can sometimes underestimate the potential for unexpected political maneuvers. For this specific question, the market is likely a reliable gauge of conventional wisdom in Washington, which views this policy as a long shot due to the colossal fiscal and political challenges involved. The low trading volume suggests limited attention, but the overwhelming consensus on the outcome is clear.
