The S&P 500 ended Monday almost unchanged as investors weighed renewed uncertainty around U.S.-Iran negotiations against hopes that the Strait of Hormuz could eventually reopen. With key inflation data due this week, Polymarket traders are leaning toward another positive open Tuesday.
The S&P 500 slipped 0.06% to close at 7,753.11, after opening at 7,751.74. The Aug. 11 Polymarket contract implied a 59% probability that the index will open higher, although the market has been volatile as traders reassess the outlook for inflation, interest rates and the Middle East.
