S&P 500 to Exceed 10,000 Points by Year-End 2029: 68% Probability
As of May 2026, the S&P 500 has reached a historic high of approximately 7,400, driven largely by mega-cap tech dominance and an unprecedented surge in AI-driven earnings. While some market participants express concern regarding elevated P/E ratios, the mathematical path toward the 10,000 milestone appears increasingly feasible. To reach this target by December 31, 2029, the index requires a total return of roughly 35% over the next 3.6 years, which translates to a Compound Annual Growth Rate (CAGR) of approximately 8.7%.
This required growth rate is notably modest when compared to recent historical trends, such as the last decade's average yearly return of 15.62%. The primary engine for this projected appreciation is corporate earnings. Analysts have aggressively revised Earnings Per Share (EPS) forecasts, with some estimates for 2026 climbing as high as 22.6%. A critical component of this fundamental strength is Artificial Intelligence, which is expected to drive nearly 40% of all S&P 500 earnings growth in the current cycle.
Despite these bullish fundamentals, certain valuation headwinds persist. The current P/E ratio of approximately 31.83 is significantly higher than the 25-year average of 16.75, suggesting that earnings must continue to rise to support current price levels. Additionally, short-term sentiment has shown signs of nervousness, evidenced by a spike in the put/call ratio for SPY open interest. However, these indicators of volatility and bearishness do not necessarily negate the long-term upward trajectory established by structural earnings momentum.
Macroeconomic factors also play a significant role in shaping this outlook. While global growth is projected to slow slightly to 3.1% in 2026 and 3.2% in 2027, the Federal Reserve's aim for a neutral federal funds rate of 3.00% to 3.25% by late 2027 suggests a stable environment for equities. While conservative models like Goldman Sachs suggest slower annual growth of 6%, and aggressive long-term models project values as high as 12,882, the most probable outcome remains centered on the index hitting the 10,000 mark.
The forecast assigns a 68% probability to the S&P 500 reaching or exceeding 10,000 points by the end of the decade. This high probability is rooted in the fact that an 8.7% annual return is well within historical norms and supported by robust AI-integrated earnings growth. The remaining probabilities account for a 22% chance of moderate growth failing to reach the milestone and a 10% chance of stagnation or a significant market correction due to systemic shocks or valuation resets.
