Will there be a Trump economic boom?
I գնահատimate a meaningfully higher-than-market chance that at least one quarter of GDP will exceed 5% during 2025–2028, but it is still far from the base case. My independent probability is 34%, reflecting that the threshold is high and usually requires either an unusually strong expansion quarter or a rebound from weakness.
Analysis
A quarterly GDP print above 5% is a demanding bar, but over a four-year presidency it is not implausible. The main reason this is not a low-single-digit event is that the question only needs one quarter, not sustained growth, and U.S. GDP can briefly surge from policy stimulus, inventory swings, trade distortions, fiscal support, or a sharp rebound after a soft patch. If the economy experiences even one strong cyclical upturn or a post-shock bounce, the threshold can be cleared without requiring a true long-run boom.
Against that, a 5% quarter remains uncommon in a mature U.S. economy, especially outside recession recovery periods or extraordinary policy/financial conditions. Inflation-adjusted real GDP above 5% annualized is difficult to sustain because potential growth is much lower, and many quarters that look strong are pulled down by revisions or offset by weak consumer demand, tighter financial conditions, or trade drag. A Trump term could support growth through tax cuts and deregulation, but tariffs, policy uncertainty, and higher rates could just as easily cap the upside and make a 5% quarter harder to achieve than headline rhetoric suggests.
Relative to the market’s 24.7% Yes price, I think the market is somewhat too pessimistic, though not dramatically so. The market may be anchoring on the low baseline probability of any single quarter exceeding 5%, while underweighting the compounding effect of four years of observations and the possibility of one outsized rebound quarter. Still, this is not a strong mispricing: the event remains genuinely tough to hit, and most plausible paths still end with no quarter breaking 5%.
Arguments
For
- A four-year window gives enough time for at least one unusually strong quarter to occur.
- Fiscal stimulus, deregulation, or a rebound from weakness could temporarily push annualized GDP above 5%.
Against
- Most U.S. expansion quarters come in well below 5%, so the baseline is against Yes.
- Trade friction, higher rates, or weak demand could suppress the kind of surge required to clear the threshold.
Key drivers
- The event only requires one quarter above 5%, so a single rebound, inventory swing, or stimulus-driven surge can decide it.
- U.S. trend growth is usually below 5%, making the outcome dependent on volatility rather than a steady boom.
- Policy mix under Trump could boost growth, but tariffs and uncertainty could offset the upside.
- A recession or soft patch followed by recovery would materially raise the chance of a >5% quarter.
Risk factors
- The 5% threshold is high for a mature economy and rarely occurs outside exceptional circumstances.
- If growth is stable but unspectacular, the market will never see the kind of one-quarter spike needed to win.
Scenarios
Best case
The economy gets a strong fiscal or post-recession rebound quarter that prints above 5% annualized, easily satisfying the market question.
Most likely
The presidency sees several decent quarters and some volatility, but no quarter ultimately exceeds 5%, leaving the answer No.
Worst case
Growth stays positive but middling throughout the term, with no quarter close enough to 5% to create a Yes outcome.

Will the U.S. invade Iran before 2027?
AI84%MKT14%Edge+70Hidden GemThe market looks substantially more likely to resolve Yes than the current price suggests because the reporting already describes U.S. military action in Iran in 2026, and the war is still active with no durable settlement. The main uncertainty is definitional, since a strict ground-control invasion is harder to confirm than strikes and wider offensive operations.

Starbucks total global stores in 2026
AI66%MKT11%Edge+55Hidden GemI think Starbucks is materially more likely than not to report more than 41,800 global stores in 2026. The market appears to be pricing in a slowdown that is possible, but the threshold is low enough relative to Starbucks’ historical footprint growth that Yes should be favored.
