The S&P 500 suffered its steepest one-day decline in a month on Thursday as surging oil prices and earnings from Tesla Inc. (NASDAQ:TSLA) and Alphabet Inc. (NASDAQ:GOOGL) (NASDAQ:GOOG) rattled investors, but Polymarket traders are betting the benchmark index will rebound at Friday’s open.
The S&P 500 closed down 1.21% at 7,408.30 after opening at 7,418.29, marking its worst daily performance since June 23. Despite the selloff, the July 24 Polymarket contract implied a 66% probability that the index will open higher on Friday.
