The S&P 500 rallied on Thursday as semiconductor stocks rebounded and oil prices eased, but Polymarket traders are betting the benchmark index will open lower on Friday.
The S&P 500 gained 0.81% to close at 7,543.64. However, the July 10 Polymarket contract implied just a 20% probability that the index would open higher on Friday, reflecting expectations of a weaker start after the latest rally.
