U.S. stock futures were higher heading into Monday morning as investors weighed an escalating military campaign against Iran, rising American casualties, and renewed concerns over global oil supplies. The **Polygon**\-based (CRYPTO: POL) Polymarket crowd is leaning optimistic for the July 20 opening bell. The “S&P 500 (SPX) Up or Down on July 20?” betting contract currently reflects a 68% chance of an “Up” open. Early trading volume for the Monday contract sits at $12,272. ## **Why That Number Matters** The macroeconomic and geopolitical landscape over the weekend has grown increasingly complex, pulling markets in conflicting directions: - **Higher Futures:** Equity benchmarks are pointing to a divergent open. S&P 500 futures were up 0.13%, while Nasdaq 100 futures advanced 0.43%. Dow Jones futures were up 0.02%. - **Energy Supply Fears:** The U.S. military carried out a ninth consecutive night of strikes against Iran to degrade capabilities used to attack commercial vessels in the Strait of Hormuz. Consequently, energy markets remain highly elevated, with Brent crude gaining 2.33% to $90.15 per barrel. WTI crude futures were last quoted at $83.55 per barrel. - **Mounting Casualties:** President **Donald Trump** confirmed that the U.S. troop death toll has now climbed to 17 since the conflict began, signaling that the military campaign will persist. ## **The Market Outlook & Commentary** According to market commentator **Mohamed A. El-Erian**, the global economy continues to navigate a period of notable geo-economic and technological fluidity. Last week, stock market confidence was heavily shaken by geopolitical flare-ups, softer inflation data, and sector-specific valuation recalibrations. El-Erian highlights that the ongoing tech wobble, which began with highly leveraged pooled vehicles in South Korea, has intensified the debate over whether equity pricing and financial flows are properly aligned with the underlying macroeconomic landscape. He also notes that Brent crude approaching $90 a barrel risks broader macroeconomic complications, especially for central banks trying to manage the “last mile” of their disinflation fight. This week, investor attention will center on mega-cap technology earnings, including **Alphabet Inc.** (NASDAQ:GOOG) (NASDAQ:GOOGL) and **Tesla Inc.** (NASDAQ:TSLA), as well as the European Central Bank’s policy meeting. **How The Previous Bet Played Out:** As the Polymarket trade for this particular contract wasn’t open on Friday,the Thursday, July 16, Polymarket contract resolved “Down.” The market drew significant participation, closing with a final volume of $190,319. **Read Also: 5 Stocks to Buy Before the Fed's Next Move** _Photo courtesy: Shutterstock_ ### Related Stocks - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) - [.SPX.US](https://longbridge.com/en/quote/.SPX.US.md) - [GOOG.US](https://longbridge.com/en/quote/GOOG.US.md) - [GOOGL.US](https://longbridge.com/en/quote/GOOGL.US.md) - [07766.HK](https://longbridge.com/en/quote/07766.HK.md) - [TESL.US](https://longbridge.com/en/quote/TESL.US.md) - [TSLZ.US](https://longbridge.com/en/quote/TSLZ.US.md) - [TSDD.US](https://longbridge.com/en/quote/TSDD.US.md) - [TSLQ.US](https://longbridge.com/en/quote/TSLQ.US.md) - [TSLT.US](https://longbridge.com/en/quote/TSLT.US.md) - [UCO.US](https://longbridge.com/en/quote/UCO.US.md) - [USO.US](https://longbridge.com/en/quote/USO.US.md) - [TSLG.US](https://longbridge.com/en/quote/TSLG.US.md) - [SPY.US](https://longbridge.com/en/quote/SPY.US.md) - [TSLL.US](https://longbridge.com/en/quote/TSLL.US.md) - [BNO.US](https://longbridge.com/en/quote/BNO.US.md) - [IVV.US](https://longbridge.com/en/quote/IVV.US.md) - [TSLR.US](https://longbridge.com/en/quote/TSLR.US.md) - [GGLS.US](https://longbridge.com/en/quote/GGLS.US.md) - [VOO.US](https://longbridge.com/en/quote/VOO.US.md) - [TSLS.US](https://longbridge.com/en/quote/TSLS.US.md) - [GOOW.US](https://longbridge.com/en/quote/GOOW.US.md) - [GGLL.US](https://longbridge.com/en/quote/GGLL.US.md) - [TSLI.US](https://longbridge.com/en/quote/TSLI.US.md) - [TSLO.US](https://longbridge.com/en/quote/TSLO.US.md) - [TSLW.US](https://longbridge.com/en/quote/TSLW.US.md) - [TSLY.US](https://longbridge.com/en/quote/TSLY.US.md) - [TSYY.US](https://longbridge.com/en/quote/TSYY.US.md) - [TYYY.US](https://longbridge.com/en/quote/TYYY.US.md) - [CRSH.US](https://longbridge.com/en/quote/CRSH.US.md) - [TSLP.US](https://longbridge.com/en/quote/TSLP.US.md) - [09366.HK](https://longbridge.com/en/quote/09366.HK.md) - [MAGX.US](https://longbridge.com/en/quote/MAGX.US.md) - [SPLG.US](https://longbridge.com/en/quote/SPLG.US.md) - [SPXL.US](https://longbridge.com/en/quote/SPXL.US.md) - [UPRO.US](https://longbridge.com/en/quote/UPRO.US.md) - [SSO.US](https://longbridge.com/en/quote/SSO.US.md) - [SH.US](https://longbridge.com/en/quote/SH.US.md) - [SPXS.US](https://longbridge.com/en/quote/SPXS.US.md) - [SPXU.US](https://longbridge.com/en/quote/SPXU.US.md) - [SDS.US](https://longbridge.com/en/quote/SDS.US.md) - [SPYI.US](https://longbridge.com/en/quote/SPYI.US.md) - [JEPI.US](https://longbridge.com/en/quote/JEPI.US.md) - [XYLD.US](https://longbridge.com/en/quote/XYLD.US.md) - [GOOY.US](https://longbridge.com/en/quote/GOOY.US.md) - [GOU.US](https://longbridge.com/en/quote/GOU.US.md) - [GOOX.US](https://longbridge.com/en/quote/GOOX.US.md) - [GOOP.US](https://longbridge.com/en/quote/GOOP.US.md) - [.NDX.US](https://longbridge.com/en/quote/.NDX.US.md) - [.DJI.US](https://longbridge.com/en/quote/.DJI.US.md) ## Related News & Research - [Oil prices hover at six-week high as Middle East shipping risks escalate](https://longbridge.com/en/news/293555449.md) - [US Cash Crude-Coastal medium sour grades rise on Iran war, wide Brent/WTI spreads](https://longbridge.com/en/news/293255058.md) - [Oil extends gains on fresh Mideast supply risks](https://longbridge.com/en/news/293418453.md) - [ROI-Iran war 'stagflation' premium quietly mounts: McGeever](https://longbridge.com/en/news/293345401.md) - [Tesla is betting its future on Optimus.
