China overtakes USA’s economy by 2030?

The central issue is that this market is about nominal GDP, not PPP, and by nominal terms the U.S. still has a substantial lead. Recent reporting suggests China is around two-thirds the size of the U.S. in nominal GDP, with the gap still on the order of more than $10 trillion. Closing that gap by 2030 would require several things to go right at once: China would need to sustain materially faster growth than the U.S. for the next several years, avoid a sharper slowdown, and likely benefit from a meaningful renminbi appreciation or U.S. dollar weakness. That combination is possible, but it is not the base case given current trends.

The bearish case for China is strong because the growth convergence story has weakened. China’s structural headwinds, including property-sector stress, demographics, debt overhang, and lower trend growth, make it hard to assume a rapid catch-up. Even if China grows faster than the U.S. in real terms, nominal GDP in dollars is sensitive to exchange rates, and a flat or weaker renminbi can easily prevent overtaking even with decent domestic growth. In other words, China does not just need to be strong; it needs the U.S. to be relatively weak in dollar terms, or the currency relationship to move sharply in its favor.

The market’s 14% Yes price does not look wildly off, but I would shade it slightly lower because recent 2026 commentary has shifted away from the idea that China is on a 2030 catch-up path. The market may be embedding a small tail chance of a dollar slide or an unexpectedly strong Chinese rebound, which is reasonable, but the evidence still points to a mostly one-sided No outcome. If anything, the bigger mispricing risk is on the No side only if one believes a major exchange-rate or policy surprise is more likely than current data implies; absent that, Yes remains a low-probability event.
