The S&P 500 had a nice day on Tuesday—up 0.89% to close at 7,509.20, powered by strong corporate earnings and a rebound in semiconductor stocks. But if you ask the crowd on Polymarket, that momentum might not carry over to Wednesday.
The prediction market's contract for the July 22 S&P 500 open is pricing in just a 15% chance that the index opens higher. That's a pretty bearish signal, and it's not coming out of nowhere. Rising oil prices and renewed inflation fears are casting a long shadow over what's otherwise been a solid earnings season.
Oil Prices Are the Spoiler
Brent crude climbed above $92 a barrel on Wednesday after the U.S. carried out its 11th consecutive night of strikes on Iran. That's a lot of geopolitical tension, and markets hate uncertainty. Speaking at the ASEAN Foreign Ministers' meeting in the Philippines, U.S. Secretary of State Marco Rubio said Washington remains committed to diplomacy but questioned Tehran's willingness to negotiate. "The problem we're having right now is that they're not serious about talks," Rubio said.
The oil price surge threatens to complicate the inflation outlook just days after softer CPI and PPI reports had boosted market sentiment. According to CME FedWatch, traders now see roughly a 24% chance of a July rate hike and about a 69% probability of at least a quarter-point increase by September. That's a quick shift in expectations, and it's making investors nervous.
Earnings Season Is in Full Swing
Wednesday is one of the busiest days of earnings season, with Alphabet (GOOGL), Tesla (TSLA), IBM (IBM), Texas Instruments (TXN), and AT&T (T) all set to report. Investors are looking for evidence that spending on artificial intelligence infrastructure remains strong enough to justify elevated technology valuations—especially after semiconductor stocks bounced sharply on Tuesday.
So far, the numbers have been impressive. Nearly 88% of the S&P 500 companies that have reported second-quarter results have beaten analysts' profit estimates, according to FactSet. But strategists have warned that companies now face an unusually high earnings bar after the market's strong run. Even solid results may not be enough to satisfy investors if the macro backdrop turns sour.
The Bear Case in a Nutshell
The resurgence in oil prices is the wild card. Just when inflation seemed to be cooling, higher energy costs could reignite price pressures and force the Fed to act. That's why S&P 500 futures slipped 0.33% early Wednesday, and why Polymarket traders are betting on a down open.
How the Previous Bet Played Out
For context, the S&P 500 opened Tuesday at 7,489.95, above Monday's close of 7,443.28, so the July 21 Polymarket contract resolved "Up." That contract recorded about $20,156 in traded volume before settling—one of the quietest prediction markets in weeks. Activity has continued to fade following the heavy participation seen at the start of July, suggesting traders remain cautious despite the market's recent rebound.
So, will the S&P 500 open up or down today? The smart money—at least on Polymarket—says down. But with earnings season delivering beats and oil prices dictating the narrative, anything can happen.
