Elon Musk says global economy could grow 10-fold by 2036 if another world war is avoided, Jim Chanos doubts

Elon Musk, the CEO of SpaceX and a leading figure at Tesla, said the global economy could expand as much as 10 times its current size by 2036, as long as humanity avoids a third world war, according to a report published by Yahoo Finance.

The comments, framed as a long-horizon view of economic growth, position Musk’s thinking alongside the broader debate over how quickly new technologies can scale and how much demand they can unlock. Musk’s scenario is explicitly conditional, with the scale of growth tied to the absence of catastrophic global conflict.

Jim Chanos, a well-known investor who has built a reputation around skepticism toward long-running market narratives, was also referenced in the same Yahoo Finance piece. The article says Chanos is not persuaded by Musk’s outlook, underscoring the gap between optimistic technology-linked forecasts and investors who stress historical uncertainty and downside risk.

For markets, the exchange matters less for the specific “10x” number than for what it indicates about competing assumptions. Musk’s forecast reflects a view that economic activity can compound rapidly over a decade-long window if new capacity and productivity gains materialize at scale. Chanos’s skepticism, as described in the report, highlights an opposing stance: that such projections often understate how quickly funding constraints, regulation, geopolitical shocks, or slower adoption can derail even credible technology roadmaps.

The fact that Musk’s remarks span both space and automobiles makes the framing especially notable. Tesla’s business is tied to consumer and enterprise adoption of electric vehicles, charging infrastructure, and manufacturing scale. SpaceX’s business depends on government and commercial demand for launch services and related capabilities. When the same executive projects very high global growth for the coming decade, the market tends to read it as a proxy for demand resilience and expanding willingness to spend across sectors.

Even so, the Yahoo Finance report provides only a limited window into the underlying mechanics of Musk’s projection. It does not, in the material referenced in the prompt, lay out a detailed model of how the “10x” figure would be achieved, what time path the growth would follow, or which technologies and policy conditions would be necessary to sustain it. It also does not specify what Chanos’s counter-arguments are beyond the summary characterization that he is not buying the thesis.

That gap is important because large growth forecasts are often most controversial at the assumption level. Without disclosed drivers, investors are left to interpret the remark as either a high-level vision or an implicit endorsement of demand expansion that would benefit multiple Musk-led ventures. For now, the best-supported takeaway from the report is the existence of a public divergence: Musk offering a bold conditional scenario for the global economy, and Chanos questioning the credibility of that scenario.
