Elon Musk has endorsed a highly optimistic economic thesis from ARK Invest, arguing that the rapid expansion of artificial intelligence is already creating an “AI riptide” across the economy. The discussion began with ARK futurist Brett Winton and was amplified by Musk, who agreed with Cathie Wood’s argument that AI inference—the processing of AI models to generate outputs—has increased roughly 25-fold in a year. Wood believes this exponential increase could eventually push U.S. real GDP growth toward double-digit annual rates, although that forecast is far more aggressive than current economic data suggests.
Wood’s argument is based on the idea that AI is moving beyond a technology-sector boom and becoming a broad productivity engine. As AI systems become cheaper, more capable and more widely deployed, businesses could automate tasks, increase output and reduce the cost of producing goods and services. In this scenario, the economic impact would compound as companies reinvest AI-generated gains into additional computing capacity and applications. Musk’s endorsement gives the thesis additional attention, but it remains a projection rather than an established economic trend.
The major problem is the gap between this optimistic forecast and the economy’s current performance. According to the article, U.S. real GDP growth was only 1.5% in the second quarter of 2026, while PCE inflation stood at 3.7%. Those numbers are nowhere near the growth rates implied by Wood’s model, meaning AI would have to generate an extraordinary acceleration in productivity to produce the projected outcome. The article therefore presents Wood’s prediction as a dramatic scenario rather than something supported by current macroeconomic data.
For investors, the more immediate implication is that AI could create a widening divide between companies that successfully exploit the technology and those that do not. Wood argues that frontier AI companies could see revenues expand by five to ten times, while businesses without meaningful AI advantages could face higher costs and increasing pressure on capital. The central investment question, therefore, is not simply whether AI will transform the economy, but which companies will capture the productivity gains—and which may be disrupted by them.
