Citi Sees AI Adoption Driving S&P 500 Gains in 2026
Citi expects a shift in market leadership from AI “enablers” to AI “adopters” as investors head into what could be a more volatile 2026. With the bull market entering its fourth year, volatility is likely to increase, making it harder to separate winners from losers in the AI race. Even so, Citi strategists remain constructive, citing an accommodative Federal Reserve, earnings growth above consensus, and a stronger fiscal boost from the OBBBA. Together, these factors support a year-end S&P 500 target of 7,700. That forecast is above the MarketWatch consensus of 7,500, which already implies roughly 10% upside from Friday’s close. Citi projects total market returns of around 13% in 2026 but expects leadership to rotate away from companies that build AI infrastructure toward firms that successfully adopt AI to boost productivity. The firm also anticipates broader participation across the index. Starting from elevated valuations, U.S. equities will face growing pressure to deliver strong fundamentals to justify prices. Citi’s base-case target of 7,700—outlined by Scott Chronert, Drew Pettit, and Patrick Galvin in the firm’s 2026 U.S. equity outlook—assumes S&P 500 earnings of $320 per share and a valuation multiple of 24 times earnings. While that represents only modest compression from current levels, Citi warns that greater dispersion in returns, especially among AI-related stocks, will make stock selection more difficult. Wall Street consensus earnings estimates for 2026 are closer to $310 per share, though Citi points to the ongoing resilience of corporate earnings. AI remains a powerful tailwind, but Citi sees investor focus gradually shifting away from hyperscalers, whose outlook remains debated, toward companies that can effectively integrate AI into their business models. The firm also expects more idiosyncratic performance among AI enablers, which now make up roughly 40% of the S&P 500, adding complexity to portfolio construction. To benefit from broader market leadership, Citi recommends positioning for positive earnings revision momentum in value, cyclical, and small-cap stocks. Growth stocks, including mega-cap technology names, will need continued earnings beats and guidance upgrades to support valuations. Citi’s outlook also assumes the Fed will cut rates twice in early 2026—earlier than markets currently expect—as higher unemployment emerges as a side effect of AI-driven productivity gains. The firm forecasts the U.S. 10-year Treasury yield will fall to 3.75% by the end of 2026, from about 4.18% today. In a bull-case scenario, stronger-than-expected earnings growth could push the S&P 500 to 8,300. In a downside scenario marked by weaker fundamentals and multiple compression, Citi sees the index falling to 5,700.
