S&P 500 hits record 7,022.95 amid Madison Air IPO and US-Iran talks progress

The S&P 500 closed at a record 7,022.95 alongside Madison Air’s IPO. On Polymarket, the odds for the S&P 500 closing higher on April 15 are at 99.9% YES, up from 58% just 24 hours ago.

The rally coincides with positive signals from the Semafor World Economy Summit, where US-Iran talks have reportedly made progress. The S&P 500 market on April 15 has 364 days until resolution, and the near-100% odds show traders are almost certain of continued gains.

Trading volume hit $108,566 in actual USDC over the past 24 hours. The largest price swing was a 15-point drop midday, which reversed quickly. That volume suggests real conviction behind the move, not just sentiment.

For traders, buying YES at 99¢ offers minimal upside but low reversal risk. A 1¢ move could signal overreaction or news fatigue.

Watch for statements from the Semafor Summit, particularly around US-Iran negotiations. Hard details on agreements or disruptions could swing these odds. Surprise inflation figures or earnings misses would also be worth monitoring as potential challenges to the current pricing.
