Trump's Approval Rating Is Likely to Land Below 40 by September

President Trump's approval rating is likely to settle somewhere in the low-to-mid 39s by late September, according to the money tracking the RealClearPolitics average — but bettors have grown increasingly uncertain about exactly where within that depressed range it lands. What was a relatively focused bet has scattered, and that scattering is itself the signal.

In recent days, the 40.0-to-40.2 outcome — which had briefly captured a meaningful share of the market — collapsed sharply, shedding ground in a single session. That money did not leave the table; it migrated downward, spreading across outcomes in the 39.1-to-39.9 range and even into territory below 38.8. No single landing zone commands better than a quarter of the total, leaving the field genuinely open within a narrow but telling corridor. The picture these markets collectively paint is not of a presidency recovering its footing, but of one whose support appears to be drifting lower with no near-term catalyst visible to halt it.

The best-supported single outcome — a rating between 39.7 and 39.9 — leads the field at 24%, with 39.4-to-39.6 close behind at 23%. The money, such as it is on roughly $100,000 in total volume, does not bet on a rebound. What would have to be true for this pricing to make sense? Bettors would need to believe that no major economic rally, foreign-policy win, or political reset arrives before September 25 — that the ambient drag of tariff uncertainty, inflation fatigue, and partisan entrenchment simply continues to erode the average at a slow, steady rate.

The near-certain removal of Trump from office before any of this resolves is not a factor the money takes seriously: the probability of Trump leaving the presidency before 2027 sits at 6%, and the probability of his departure before September 30 is effectively zero. The presidency is stable; the approval is not. That distinction matters enormously for interpreting the signal. This is not a story about political crisis — it is a story about a slow, grinding erosion of public standing with no shock event driving it.

For anyone tracking the political environment heading into the 2026 midterm cycle, a president averaging in the high 38s to low 39s by late September would represent a significant headwind for Republican candidates in competitive districts. Approval at that level historically correlates with meaningful seat losses in the House, and it narrows the margin for error in Senate races the GOP had hoped to treat as safe. The money is not predicting a wave — it is pricing in persistent weakness.

What would break the market's read? A sharp improvement in economic sentiment, a foreign-policy moment that consolidates public support, or a polling methodology shift at RealClearPolitics could push the average back above 40 and invalidate most of the current distribution. The below-38.8 tail — now at 10% — is the scenario where deterioration accelerates rather than plateaus. Neither path looks likely in these markets. The baseline, increasingly, is simply more of the same: a presidency governing near its floor, stable in office and settled in its unpopularity.
