The S&amp;P 500 heads into Monday’s session facing a fresh wave of geopolitical pressure, with S&amp;P 500 futures slipping 0.09% early on Monday. After digesting Friday’s jobs data and market action, investor confidence has been rattled by a total breakdown in weekend diplomatic talks.



The Polygon-based (CRYPTO: POL) Polymarket crowd is leaning decisively bearish for the Monday open. The “S&amp;P 500 Opens Up or Down on May 11?” market currently reflects a 38% chance of an “Up” open, plunging 12% following the weekend’s diplomatic breakdown. Early trading volume for the Monday bet currently sits at $13,977.

<h2>Why That Number Matters</h2>



Hopes for a near-term diplomatic breakthrough were shattered late Sunday when President Donald Trump explicitly rejected Iran’s response to a U.S.-backed peace proposal. Posting on Truth Social, Trump declared the Iranian terms “TOTALLY UNACCEPTABLE!”



Iran’s counter-proposal reportedly demanded an end to U.S. military pressure, sanctions relief, compensation for war damages, and continued control over the Strait of Hormuz. The failure to reach a consensus has reignited fears of a prolonged global energy supply shock.



<ul>
<li>Energy Spike: Crude oil prices surged on the breakdown in negotiations, with WTI crude jumping 3.31% to $98.58 per barrel and Brent crude advancing 3.19% to $104.52, at the time of publishing this piece.</li>



<li>Futures Slide: U.S. stock futures slipped in response to the escalating tensions. S&amp;P 500 futures dropped 0.09%, while Dow futures fell 0.02%.</li>



<li>Continued Conflict: Israeli Prime Minister Benjamin Netanyahu added to the hawkish sentiment, warning that the conflict with Iran is “not over” and citing unresolved concerns regarding Iran’s nuclear infrastructure, proxies, and ballistic missile capabilities.</li>
</ul>



<h2>The Bull Countercase</h2>



Despite the geopolitical headwinds, pockets of market resilience remain visible. Nasdaq 100 futures managed to rise 0.02%, suggesting that some investors are still rotating into tech stocks for strength amidst macroeconomic uncertainty.



How The Previous Bet Played Out: Despite a Thursday pullback in the S&amp;P 500, the Polymarket crowd correctly anticipated a higher Friday open, resolving the May 8 bet as “Up”. It settled with a traded volume of $177,709.
