S&P 500 (^GSPC) price forecast

S&P 500 is trading at 7,412. Over the next 4 hours our simulation puts it between 7,365 and 7,461— that's the 10th-to-90th percentile of 20,000 modelled outcomes, so roughly four times in five it should land inside that band. The odds of finishing higher are near a coin toss, so the model claims no directional signal here — the range is the whole forecast. These are probabilities, not predictions of certainty, and the backtest below shows exactly how often the model has been right.

How accurate has this model been on S&P 500?

Every forecast site claims accuracy. Here is ours, measured by walk-forward backtest on data the model never saw during training. Where it has no edge over a naive baseline, we say so.

Backtested on 1910unseen samples. "No edge" means the model was no better than assuming the recent trend continues — an honest result, and a common one.

What the model is saying about S&P 500

The model's central expectation for the S&P 500, currently near 7,412, is modestly higher across all horizons. Over one week it projects about 7,434 (+0.29%, 60% chance of rising), with a P10–P90 band of roughly 7,214 to 7,661. One month points to about 7,496 (+1.13%, 69% up), and one year to about 8,545 (+15.28%, 81% up), spanning 6,904 to 10,580. Reliability is flagged as moderate, low, and very low respectively. The backdrop is annualised volatility of 16.53% and a nearly flat trailing month (+0.58%), so the wide ranges reflect ordinary uncertainty compounding over time. Bluntly, the ML model shows no measurable edge: at 1, 7 and 30 days its accuracy (54%, 60.6%, 67.2%) matches or trails the naive baseline (54.8%, 60.6%, 67.2%). It is not adding directional insight. A volatility spike, a break outside the stated ranges, or a shift in the flat momentum would undercut this outlook, and the low-reliability longer horizons deserve particular skepticism.

How to read this forecast

We don't publish a single price target, because nobody can know one. Instead the engine runs 20,000 simulated futures for S&P 500 and reports the band containing the middle 80% of them — the 10th to 90th percentile. A wide band means genuine uncertainty; a narrow one means the recent range has been calm. The odds higher figure is a calibrated probability: when we say 60%, outcomes of that kind should finish higher about 60 times in 100. Near 50% there is no directional signal at all, and the range itself is the entire forecast.

Short-horizon direction has only a small measurable edge; long-horizon numbers reflect drift plus widening uncertainty and should be read as ranges, not targets. Figures update hourly.
