Cathie Wood, Chief Investment Officer and portfolio manager at ARK Invest, argues that five converging innovation platforms — artificial intelligence, robotics, energy storage, blockchain, and multiomics, the integrated study of genomes and other biological data — could push sustainable US productivity growth to 5–6%, well above the 2–3% range investors have grown accustomed to since the Industrial Revolution. In her latest investor letter, Wood contends that real GDP growth could accelerate beyond 7% annually, a scenario she believes would resemble the five-decade expansion that culminated in the Roaring Twenties rather than any period of the last hundred years.\n## A “Back to the Future” Rate Regime

Wood frames the current environment as “back to the future.” Interest rates, having bottomed near zero during the COVID crash, are rising in a pattern that echoes the pre-Federal Reserve era, when short-term rates tracked nominal GDP growth while long rates reflected deflationary technological undercurrents. During the Industrial Revolution, the yield curve was inverted more than 60% of the time without signaling a recession, and ARK believes a similar inversion today would be a bullish signal for equities rather than a warning. In modern financial history, an inverted curve — short-term borrowing costs rising above long-term yields — has ranked among the most closely watched recession indicators, which is what makes ARK’s reading a deliberately contrarian one.

Collapsing Technology Costs and “Good Deflation”

The core driver, Wood writes, is the collapse in technology costs. AI inference costs have fallen by more than 99% annually since the cloud’s debut and the deep learning breakthroughs of the past decade, while whole-genome sequencing has dropped from $2.7 billion in 2003 to under $100.

This “good deflation” is already producing macroeconomic effects: ARK notes that AI inference demand grew roughly 25-fold in 2025, and estimates that Anthropic, the AI company behind the Claude models, saw its annualized revenue run rate climb from $9 billion to $65 billion between December and July — growth that, in the firm’s view, undermines the narrative of an AI hype bubble.

Inflation, Oil, and the Case for Equities

On inflation, Wood points to alternative data suggesting official measures overstate the problem. While government headline and core PCE readings stood at 3.7% and 3.3% in July, the Truflation index — which tracks more than 16 million prices daily — showed headline inflation at 2.5% and core at 2.1%, within striking distance of the Fed’s 2% target. That spread — more than a full percentage point on both measures — is among the letter’s most directly checkable claims, since official and alternative gauges are updated on regular, public schedules.

Wood attributes part of the gap to energy. Gasoline prices are up about 33% year-over-year amid the Iran War, but she expects a significant decline once the conflict subsides — potentially toward $30–35 per barrel — citing surging production from the UAE and other quota-breaking producers. Crude output and the conflict’s path are therefore among the near-term variables most likely to test that piece of the forecast.

Monetary Policy Under a New Fed Chair

Monetary policy, in Wood’s view, reinforces this outlook. With Kevin Warsh installed as Fed Chairman, she expects Volcker-style discipline, lower inflation, and potentially a declining gold price as productivity gains strengthen the dollar — though she flags bitcoin alongside gold as a hedge against counterparty risk from disruption.

Risks to the Forecast

The forecast is not without risks. Roughly $16 trillion in private equity and private credit, much of it funded with floating-rate debt, could face severe stress if short-term rates rise to 6–8% as ARK projects; federal debt service, meanwhile, would surge by some $800 billion under such a scenario. Floating-rate borrowings reset against short-term benchmarks, so that slice of the debt stack would feel higher rates quickly if the projection played out.

A Call to Reallocate

Wood’s conclusion is a call to reallocate. The classic 60/40 portfolio — 60% equities, 40% bonds — suited the falling-rate era of 1981–2021, she argues, but a deflationary technology boom demands heavier exposure to equities — and, notably for crypto-focused investors, to Bitcoin. For readers tracking the argument, the markers to watch are the ones the letter itself identifies: the shape of the yield curve, the gap between official and alternative inflation readings, the direction of oil, and the Fed’s course under Warsh.
