Kalshi prediction markets assign the S&P 500, an index tracking 500 major U.S. publicly traded companies, a 51.8% chance of reaching 8,000 by year-end, down from 79% last month but above 19% at the start of 2026. JPMorgan has shifted from a cautious summer view to a bullish strategy, urging investors to maintain overweight equity positions through year-end and forecasting new record highs for U.S. and global equities. The bank expects geopolitical and interest-rate-driven weakness to last days or weeks rather than quarters, citing improving earnings revisions, three consecutive months of gains in the eurozone Purchasing Managers' Index, oversold semiconductor and South Korean markets, and continuing AI infrastructure demand. The S&P 500 has gained 12% year to date, reached a record close of 7,798.99 in mid-August and closed Wednesday at 7,666.60 after rising 0.46%.
