Every S&P 500 Index forecast from Kunkafa’s AI market analysis names a direction, a duration and a level. This weekly report takes every S&P 500 Index price forecast Kunkafa published from Monday 21 to Monday 28 September at 95% confidence and above, and asks one question of each: inside its own duration, how far did price actually go toward that level?

Kunkafa’s confidence floor

The written figures describe the 95% view. Choose a lower floor to see the same forecasts from a wider net.

Measured as a share of the distance to the forecast level, not as a price change, the 8,055 forecasts that settled came out like this:

  1. went 300% or more16.7%
  2. went 200 to 300%13.7%
  3. went 125 to 200%32.8%
  4. went 100 to 125%, reaching the level26.5%
  5. went 75 to 99%2.5%
  6. went 50 to 75%2.1%
  7. went 25 to 50%2.1%
  8. went under 25%3.6%
of the forecasted distance
        

8,055 forecasts at Kunkafa’s confidence of 95% or higher, both directions, every duration up to 4 days.

Every band is a share of the distance to the forecast level, not a price change: 100% is the level itself, 300% is three times that distance, 50% is halfway there.

Confidence, and what it was worth

Every forecast carries Kunkafa’s confidence. The higher the confidence, the further price tends to go. The rest of this report keeps to 95% and above; here every band from 60% up is shown, so the value of confidence is visible.

How this was counted

  • Source: Kunkafa’s outcome of live S&P 500 Index forecasts, opened between 21 and 28 September 2026, at Kunkafa’s confidence of 95% or higher, both directions, every duration; every section but the confidence breakdown counts this same population.
  • Only settled forecasts are counted: the full duration had elapsed by the time of this report, and for durations beyond two days it had elapsed at least a day before 28 September.
  • “Reached” means price touched the forecast level at some point inside the forecast’s duration; expiring without touching it counts as not reached, whatever happened afterwards.
  • No forecast was removed, re-weighted or selected by outcome.

Kunkafa’s forecasts are probabilities, not prophecy. Past results describe what happened; they do not promise what could happen next. Probability, not advice.
