When most people hear "inflation stuck above 3%," "AI replacing workers," and "political uncertainty," they don't immediately think "bull market paradise." But Ed Yardeni isn't most people. The Wall Street veteran is sticking with the bold call he made back in 2020: we're living through a decade-long boom, and 2026 is just another year in what he's dubbed the Roaring 2020s.
In his latest Tuesday note, Yardeni sounded downright cheerful about it all. GDP? At record highs. Corporate profits? Record highs. Consumer spending? You guessed it. The data, he argues, backs up the idea that this rally has plenty of runway left—even if the path forward looks bumpier than anyone expected when the pandemic ended.
The BRAIN Revolution: Thinking Machines Drive the Boom
Yardeni's original thesis from 2020 was that the post-COVID era would mirror the Roaring 1920s, but with a twist. Instead of electricity and automobiles powering growth, this boom would be driven by technology that "supplements or replaces the brain." And he's not backing down from that idea.
"Today's innovations produced by the IT industry are revolutionizing lots of other ones, including manufacturing, energy, transportation, healthcare, and education," Yardeni wrote. He points to what BCA Research called the BRAIN Revolution—biotech, robotics, artificial intelligence, and nanotech—as the engine behind today's productivity surge.
That productivity story is central to his 2026 outlook. He's forecasting 3% real GDP growth next year, powered by 2.5% productivity gains, even as employment and labor force growth slow to just 0.5%. Translation: we're getting more output per worker, which keeps the economy humming even if hiring slows down.
The catch? The job market might look weaker on the surface, especially for recent college graduates. "The unemployment rate is likely to end this year at 4.5%, primarily because of the rising jobless rate among recent college graduates due to the rapid proliferation of AI. The same may be said about 2026," Yardeni said. So if you're graduating soon, maybe don't count on that entry-level analyst job being a slam dunk.
Target Acquired: S&P 500 at 10,000
Yardeni's stock market forecast remains one of Wall Street's most optimistic. He expects S&P 500 operating earnings per share to climb from $268 in 2025 to $310 in 2026, eventually hitting $450 by 2029. Apply a forward price-to-earnings ratio between 18 and 22, and you get a range of 9,000 to 11,000 for the index by decade's end.
"Let's split the difference and aim for 10,000 by the end of the Roaring 2020s," Yardeni said. That would represent a 210% gain from the 2019 close of 3,230—ambitious, sure, but not unprecedented when you look at past multi-decade rallies. For those tracking along at home, the Vanguard S&P 500 ETF (VOO) is the standard way to play that index move.
But here's where it gets interesting: Yardeni doesn't think the current mega-cap tech concentration is sustainable. "Almost all the bubble is in the Information Technology and Communication Services sectors," he noted, which together now account for 45% of S&P 500 market cap. That's a lot of eggs in one very expensive basket.
His solution? Diversify. He's recommending increased exposure to financials, industrials, and especially healthcare, which he sees as a rising star heading into 2026. The boom is real, he's saying, but maybe don't put it all on the Magnificent Seven.
Productivity Solves the Inflation Problem
While the Fed keeps wrestling with inflation, Yardeni thinks the economy might naturally disinflate thanks to stronger productivity growth. He highlights that unit labor costs—a key driver of wage inflation—rose just 2.5% year-over-year in the second quarter, and could fall further in 2026. If that happens, the Fed might finally hit its 2.0% inflation target next year.
His monetary policy base case includes one rate cut in 2026, bringing the federal funds rate to 3.50%-3.75%, with 10-year Treasury yields staying in the 4%-5% range. He views these levels as neutral territory—neither goosing growth nor choking it off.
Yardeni also expects the Federal Reserve to become more independent in 2026, despite President Donald Trump likely appointing a dovish replacement for Jerome Powell when his term expires in May. Whether that independence materializes remains to be seen, but it's part of Yardeni's optimistic scenario.
Gold Shines, Bitcoin Stumbles
Yardeni is decidedly bullish on gold, calling for a jump to $5,000 by the end of 2026 and $10,000 by 2029. The drivers? Central bank buying, Chinese retail demand, and geopolitical uncertainty—the classic gold playbook.
Bitcoin (BTC), on the other hand, is getting no love. The 2025 GENIUS Act opened the door for stablecoins to be used in payments, which Yardeni sees as gutting one of bitcoin's core use cases. "The recent severe selloff suggests that it might be digital fools' gold," he said. Ouch.
He expects another rough year for Strategy Inc. (MSTR), Michael Saylor's company that's heavily invested in bitcoin. While past dips have been buying opportunities for crypto bulls, Yardeni doesn't see a compelling reason to jump in this time around.
Must All Roaring Decades End in Tears?
Ever since Yardeni first floated his "Roaring 2020s" thesis, the obvious question has been: doesn't every roaring decade end in disaster? The 1920s gave way to the Great Depression, after all.
Yardeni's response: not necessarily. "Trump's tariffs have already stress-tested the U.S. and global economies for a 1930s-style Smoot-Hawley scenario without much signs of stress," he said. And if the BRAIN Revolution keeps driving productivity and profits, this party could last well into the next decade.
The key variable, in Yardeni's view, is productivity. As long as output per worker keeps climbing, growth can continue even if traditional metrics like job creation and inflation don't behave the way they used to. It's a different kind of boom, powered by different forces, and he's betting it has staying power.
Whether 2026 turns out to be just another year in a roaring decade or the moment when reality catches up with optimism, we'll find out soon enough. But for now, Yardeni isn't hedging his bets.
