S&P 500's Path Toward 10,000 Gains Credibility on AI-Fueled Earnings

The S&P 500 is pushing toward the 8,000 mark, and a milestone once viewed as outlandish is increasingly being discussed on Wall Street: 10,000. The shift reflects an unusually powerful earnings cycle, with S&P 500 profits up more than 50% year over year in the second quarter and third-quarter earnings projected to rise more than 30%. AI-linked companies continue to lead the acceleration, extending momentum from the index's recent AI boom. Technology-sector profits and related infrastructure spending have repeatedly come in ahead of expectations, helping lift overall results. 10,000 Moves Into the Mainstream ETF provider Roundhill has launched a product tied to the S&P 500 reaching 10,000 by January 2030. Strategist Ed Yardeni has also argued the level is achievable before decade's end. On a more aggressive timeline, Societe Generale strategist Manish Kabra projects the index ending 2026 around 8,000 and says 10,000 could be within reach as early as 2027 under a stronger bull-case scenario. The index is currently trading near record territory around 7,700–7,800, so a move to 10,000 would still imply roughly 30% upside. That is a large jump, but earnings growth has been unusually fast. FactSet forecasts third-quarter S&P 500 earnings per share to rise about 29.5%, which would potentially mark a third straight quarter of profit growth above 25%. Over the past five years, the S&P 500 has gained about 72%, rising from its 2022 low to a fresh record near 7,735. AI Remains the Engine Artificial intelligence is central to the bullish case. Nvidia, Microsoft, Meta, Amazon and other megacap technology firms are turning massive infrastructure investment into rapid gains in revenue and profit. AI-linked companies also make up a larger share of the S&P 500 than they did several years ago. That concentration is a double-edged sword. AI-driven growth has a bigger impact on index-wide earnings, but it also increases vulnerability if the investment cycle cools. For now, projections remain robust. Analysts expect full-year S&P 500 earnings to climb about 35% in 2026, then ease toward roughly 15% growth in 2027. The key issue is whether that slowdown stays orderly. Rates Remain the Biggest Headwind The main challenge to the 10,000 scenario is the cost of money. The 10-year Treasury yield is hovering around 5.3%, one of the most difficult rate backdrops for equities in decades. Higher yields raise the discount rate applied to future profits and make bonds more competitive. Even so, markets have repeatedly shown an ability to absorb higher rates as AI-related stocks continue to deliver earnings growth strong enough to offset part of the valuation pressure.
