While much of Wall Street spends its time worrying about stagflation, Cathie Wood is reading an entirely different scenario. ARK Invest’s CEO claims that US inflation is not just falling, but dramatically faster than consensus expectations, with real-time data suggesting core inflation is around 1%.
numbers behind the phone
Wood’s argument begins with data that most economists haven’t looked at closely enough. According to Truflation, a real-time inflation tracker that draws from millions of data points rather than the Bureau of Labor Statistics’ lagging methodology, U.S. CPI inflation is just 0.86% year over year.
Core inflation, which excludes volatile food and energy prices, remains at about 1%. The housing market is usually one of the most troubling components of inflation, but price pressures have been minimal.
Mr Wood predicted that official CPI readings would be “unexpectedly low” over the next six to nine months. Her paper focuses on AI-induced deflation. As artificial intelligence tools become embedded across industries, they will drive productivity gains and reduce the cost of goods and services.
According to ARK research, productivity growth is around 3% and capital spending is at a 30-year high. Companies are spending aggressively on technology infrastructure, and that spending is starting to show up in increased output rather than higher prices.
Strange economy and strong dollar
A recent analysis of ARK revealed an interesting split in the data. Consumer prices (CPI) are falling, but producer prices (PPI) are rising. That’s a rare combination. Typically, when PPI rises while CPI falls, it means that businesses are absorbing higher input costs rather than passing them on to consumers.
Wood expects that the US dollar could recover, conditional on pro-growth policies that increase returns on capital relative to global benchmarks.
ARK’s May 2026 update expects inflation to remain below 5% in 2027, eventually falling to 3%.
housing wildcard
ARK’s research reveals a huge gap in the housing market, with approximately 1.4 million buyers facing 2 million sellers. This tilts the market in favor of buyers and puts downward pressure on home prices.
Housing is the largest component of the CPI calculation. If home prices and rents continue to soften, the official inflation numbers tracked by the Fed could fall, and Wood’s theory could be backed up by data that actually drives policy. The Fed has repeatedly cited stagnant shelter inflation as a reason to keep interest rates high.
What this means for investors
Lower-than-expected inflation is likely to speed up the Federal Reserve’s rate cut schedule, which is generally positive for risk assets such as stocks and cryptocurrencies. Growth stocks tend to outperform in environments with lower interest rates. This is because future cash flows become more valuable when discounted at a lower interest rate.
ARK’s flagship fund suffered heavy losses during the 2022 rate hike cycle, when Wood was already arguing that inflation was temporary. The disconnect between real-time inflation tracking tools like Truflation and official government data creates real uncertainty. If lagging indicators catch up to where real-time data already exists, the market can quickly reprice.
