S&P 500 Turns Positive as U.S.-Iran Peace Talks Appear to Stall

The brief market update says the S&P 500 erased earlier losses and moved into positive territory even as negotiations involving the United States and Iran appeared to lose momentum.

Fact Check
The claim is directly sourced from the @KobeissiLetter X post dated 2026-05-11, which states verbatim that the S&P 500 erased all losses and turned green despite US-Iran peace talks appearing to stall. The Reuters article 'Wall St slips at open as US-Iran impasse lifts oil' independently confirms that the S&P 500 did open lower on May 11, 2026 due to stalled US-Iran talks, making the subsequent recovery described in the claim internally consistent. The claim accurately summarizes the primary source. Minor uncertainty remains because the Reuters article describes the open but does not explicitly confirm the intraday recovery, and the Kobeissi Letter is a financial commentary account rather than a primary market data provider.
