The S&P 500 closed Monday at 7,683.69. Polymarket currently prices a touch of 8,200 before year-end at about 28 cents and 8,600 at just 9 cents. Those levels require rallies of 6.7% and 11.9%, respectively, with 66 trading sessions left.
The question is whether SPX can make another meaningful move higher before the end of the year. I think the setup is better than the 9-cent price on 8,600 suggests.
S&P 500 Yearly Return Odds
Here’s what Polymarket is currently pricing:
Where SPX goes from here
The biggest thing holding the market back right now is rates.
The 10-year Treasury yield is above 5.2%, the 30-year is above 5.6%, and investors are pricing additional Fed tightening. Higher yields put pressure on equity valuations, especially after the S&P’s run to record highs.
That makes a straight-line rally unlikely. But it also creates a market where relatively small changes in rates can produce large moves in equities.
If inflation data cools, the Fed becomes less aggressive, or Treasury yields simply stop climbing, some of the pressure currently sitting on stocks disappears quickly. SPX doesn’t need a return to easy monetary policy. It mostly needs rates to stop moving against it.
The next few months also bring plenty of catalysts: economic data, third-quarter earnings, the October Fed meeting, November elections and another Fed decision in December. With that much ahead, pricing SPX as though it will quietly grind sideways looks aggressive.
The path higher
The first level I’m watching is 8,000. That’s only about 4% above Monday’s close and would put the index back into breakout territory.
From there, 8,200 becomes much more realistic. It’s only another 2.5% higher and would represent roughly a 6.7% move from current levels.
The more interesting contract, though, is 8,600.
At 8,600, SPX would need to rally about 11.9% from here. That’s obviously a much bigger move, but there are still 66 trading sessions left. The contract also only needs SPX to touch the level once. It doesn’t need to finish the year there.
A strong earnings season combined with even a modest decline in Treasury yields could reopen the upside very quickly.
The trade
Buy SPX 8,600 Yes at 9¢.
I’m not betting that 8,600 is the most likely year-end destination. I’m betting that a 9% chance of touching it is too low.
The position gives you exposure to a scenario where rates stabilize, earnings remain strong and investors rotate back into risk before year-end. If SPX starts clearing 8,000 and then 8,200, the 8,600 contract should reprice well before the index actually gets there.
At 9 cents, the downside is also simple: the most you lose is 9 cents per share.
I would keep the position small because this is still a tail trade. The market has to make a meaningful new high for it to pay.
What I’m watching
The 10-year Treasury remains the most important number.
If yields continue climbing toward or through 5.5%, the valuation pressure on equities gets harder to ignore and the path to 8,600 becomes much more difficult.
But if yields stabilize or start moving lower, SPX doesn’t need much additional good news for the upside trade to come back into play.
That’s why I like the 8,600 contract here. The market is pricing a large fourth-quarter rally as a long shot at exactly the moment when rates, earnings and macro data are giving SPX plenty of ways to move.
