S&P close price end of 2026?
I make the 7,800–7,999.99 band a meaningful but still minority outcome, with a probability around 24%. The index is only modestly below the range now, but there is enough time for year-end drift and volatility to pull it into the target zone.
Analysis
The most important fact is that the S&P 500 is already close to the target band, sitting just below 7,800 in recent prints. That makes the 7,800–7,999.99 outcome materially more plausible than a distant range because only a small net move is needed over the remaining months. At the same time, this is still a narrow finish window, not a directional bet on the index merely going up; a modest overshoot into 8,000+ or a pullback into the high-7,600s would both miss the contract. Given the current level and the remaining time horizon, the central case is a fairly broad distribution around the current area with a meaningful share landing inside the band, but not a majority share.
The adjacent bands matter a lot here. The market’s top prices show significant weight not just on 7,800–7,999.99 but also on 8,000–8,199.99 and 7,600–7,799.99, which is exactly what one would expect if traders believe the index is hovering near a pivot rather than locked into a single endpoint. That configuration argues against overconfidence in the target band, because a year-end close can easily end up a few tens of points higher or lower and land in a neighboring bracket. The strongest case for this band is therefore one of mean-reversion plus modest upward drift: if equities remain firm but not explosive, 7,800 to 7,999.99 is a very natural destination.
Compared with the current market price of 20% for Yes, my view is slightly more constructive, but not dramatically so. The market seems broadly efficient here, though I think it may understate how often a large index finishes in a relatively tight zone near its starting area over a multi-month horizon. Still, the contract is sensitive to late-year moves, macro shocks, and any sustained rally that pushes the S&P above 8,000. That keeps this as a solid minority probability rather than a favorite.
Arguments
For
- Arguments for Yes: The index is only slightly below 7,800 now, so the required move is small relative to the remaining time.
- Arguments for Yes: The current clustering of prices around nearby bands suggests a high chance of finishing somewhere near the target zone.
Against
- Arguments against Yes: A finish just above 8,000 is nearly as plausible as a finish inside 7,800–7,999.99, and that would lose the contract.
- Arguments against Yes: Year-end closes are vulnerable to late volatility, which can easily knock the index out of a narrow bracket.
Key drivers
- The S&P 500 is already very near the lower edge of the target range, so only a modest net gain is needed.
- The probability mass is spread across adjacent bands, indicating the finish is likely to be near current levels rather than far away.
Risk factors
- A continued rally could push the index into the 8,000–8,199.99 band instead of the target range.
- A short-term correction or volatility spike could leave the index below 7,800 at the close.
Scenarios
Best case
Equities grind modestly higher through year-end without breaking materially above 8,000, producing a close inside 7,800–7,999.99.
Most likely
The index finishes somewhere near its current level, with the most competitive outcomes split between the target band and adjacent 7,600–7,799.99 or 8,000–8,199.99 ranges.
Worst case
A late rally carries the S&P 500 above 8,000 or a pullback drops it back below 7,800, leaving the contract unresolved in the Yes range.

What will the median home value in Miami be on December 31?
AI68%MKT17%Edge+51Hidden GemMiami’s current citywide and countywide home-price measures appear to sit below $767,000, and there is not much evidence of a rapid enough near-term rise to push the overall median above that level by year-end. I think the Yes outcome is more likely than not, though some ambiguity remains about the exact measure used and Miami’s tendency for sharp neighborhood-level price dispersion.

Bitcoin price at the end of 2026
AI61%MKT14%Edge+47Hidden GemI think BTC is more likely than the market implies to finish January 1, 2027 in the mid-to-high $80,000s or low $90,000s, with the single most likely bin around $85,000 to $89,999.99. The market looks too pessimistic on a year-end grind higher from the current mid-$80Ks, though I still would not assign a dominant probability to a breakout above $95,000.

Where will 2026 rank among the hottest years on record?
AI28%MKT64%Edge-36Hyped2026 looks highly likely to finish near the very top of the global temperature rankings, but becoming the single hottest year on record is still a much harder bar to clear. I think the market is somewhat overpricing the chance of a new global record, so I lean No.
