Multiple reports say Wall Street ends the trading session with gains, highlighting strong investor interest in newly listed SpaceX shares. The listings are described as Wall Street’s biggest public offering in history, with SpaceX’s market debut driving attention and trading activity. In parallel, coverage notes that market participants also weigh broader developments, including expectations for a potential peace deal between Iran and the United States. While the reports emphasize different drivers, they converge on the same core points: equities close higher, SpaceX shares surge at their start of trading, and hopes around US-Iran negotiations support investor sentiment during the session. Overall, the combined accounts attribute the day’s rise primarily to the impact of SpaceX’s debut while citing diplomacy-related optimism as a secondary factor.
