Elon Musk weighs in on Goldman Sachs’ forecast for a $1.8 trillion space economy by 2035

Goldman Sachs’ projection that the global space economy could grow to $1.8 trillion by 2035 has become a focal point in the latest exchange between Wall Street analysts and one of the sector’s best-known entrepreneurs, Elon Musk. The forecast, highlighted in a report circulated by Yahoo Finance, frames space as a longer-term investment theme that could expand well beyond today’s launch and satellite services.

According to the report, Musk responded to the prediction, drawing attention to whether such a scale of economic activity is achievable within the stated timeframe. While the market conversation often turns on who has the most credible view of timelines, Goldman’s figure is part of a broader effort by financial institutions to put quantitative bounds around an industry that has historically been driven by engineering milestones and government budgets.

Goldman Sachs is not alone in arguing that space has the ingredients of an investable industry, including expanding satellite capacity, growing demand for data and connectivity, and the emergence of commercial providers. The firm’s $1.8 trillion-by-2035 estimate places a time horizon on that build-out and implicitly suggests that multiple revenue streams could mature together, rather than remaining isolated to a few segments.

Musk’s response, as reported, indicates how quickly these forecasts can move from research desks to public debate. For companies in space, sentiment matters in two ways: it influences how quickly new capital flows into the supply chain, and it can also shape policy and customer expectations about what capabilities will be available when.

The exchange also underscores a common tension in space economics. High-growth projections often depend on assumptions that are difficult to verify in the short run, such as how fast launch costs decline, how rapidly satellite networks can scale, and how demand for services like broadband, earth observation, and communications evolves across regions. When a top-tier bank publishes a specific dollar target, it gives the public a clear benchmark against which timelines and business models can be judged.

Even without additional disclosure in the report about the substance of Musk’s reply, the broader takeaway is that the space economy is increasingly treated as a macro theme rather than a collection of individual programs. That approach tends to appeal to investors who prefer a single, measurable growth path, but it also invites scrutiny over whether the underlying drivers can compound at the pace implied by a headline number.

For Goldman Sachs, putting a number on the opportunity can support research visibility and client discussions, especially when space-related equities and private market fundraising are in the news. For Musk and his peers, responding to such estimates is a way to challenge assumptions, correct public narratives, or push back on overly optimistic framing, depending on what was said in the response.
