The S&P 500 slipped on Tuesday as investors rotated out of artificial intelligence-linked stocks and geopolitical tensions flared again in the Middle East. Polymarket traders are now overwhelmingly betting the benchmark index will open lower on Wednesday.
The S&P 500 fell 0.45% to close at 7,503.85. The July 8 Polymarket contract implied just a 12% probability that the index would open higher on Wednesday, reflecting a sharp deterioration in sentiment as traders increasingly positioned for another weak start. The chances dropped drastically after being over 50% earlier.
