Equities Rally, Oil Tumbles as Geopolitical Tensions Ease; AI Selloff Warning from 'Big Short' Legend

## Lead US equities are rallying significantly at midday, with the Nasdaq 100 up 1.72% and the S&P 500 up 1.38%. This broad-based relief rally follows a substantial drop in crude oil prices, down 5.44%, and a retreat in Treasury yields. Geopolitical concerns appear to be easing after reports of potential Ukraine peace efforts and conflicting statements regarding US-Iran talks. Meanwhile, a 'Big Short' legend warns of a potential AI selloff tied to OpenAI and Anthropic. ## Session narrative US equities are experiencing a strong midday rally, with major indices showing significant gains. The Nasdaq 100 is leading the charge, up 1.72%, followed by the S&P 500 at 1.38%. The Dow is also up 0.94%. This positive sentiment is largely attributed to a sharp decline in crude oil prices, with WTI crude down 5.44%, and a corresponding retreat in Treasury yields, as the 10-year yield falls 1.20%. Geopolitical developments are in focus, with news of potential US efforts to jumpstart Ukraine peace talks and conflicting reports surrounding US-Iran negotiations. Specifically, Iran's foreign ministry spokesperson stated Tehran had no plans for direct talks with Washington, despite Trump's claim of an 'imminent deal.' US officials also clarified that no 'new' negotiations are planned, only ongoing talks through mediators. In corporate news, Amazon stock gained over 5% as risk appetite improved and analysts highlighted a massive $496 billion AWS order backlog. AMD shares are also advancing ahead of Q2 earnings this week. Despite the broader market optimism, a notable warning from 'Big Short' legend Steve Eisman suggests that a 'sustained' AI selloff could be triggered by issues at OpenAI and Anthropic, given their significant contribution to hyperscaler backlogs. ## Cross-asset check Equity futures are mirroring the cash market's strength, with S&P futures up 1.32% and Nasdaq futures up 1.62%. The Russell 2000 futures are also showing gains of 1.50%. In the rates market, the US 10-year yield is down 1.20% to 4.69%, while long-duration Treasuries are down 0.04%. The US Dollar Index is up 0.07%. Commodities are mixed, with WTI crude down 5.44% and Brent crude down 4.78%. Gold is down 0.39%, while silver is up 0.10% and copper is up 1.05%. Natural gas is up 0.40%. The VIX, a measure of market volatility, is down 2.56%. ## Themes & continuing stories Geopolitical de-escalation appears to be a key theme, with reports of potential US efforts to jumpstart Ukraine peace talks and the easing of tensions around Iran contributing to a risk-on environment. The significant drop in crude oil prices is another major driver, alleviating inflation concerns and supporting equity markets. However, the AI sector is under scrutiny, with a prominent investor warning of potential vulnerabilities at OpenAI and Anthropic that could trigger a 'sustained' selloff. This highlights ongoing discussions about the sustainability and valuation of the AI boom. ## What’s ahead Looking ahead, the market will be closely watching for further developments on Ukraine peace efforts, particularly as the US works on new proposals. AMD's Q2 earnings report this week will also be a significant event, with analysts anticipating strong revenue and earnings growth. Furthermore, the health and stability of key private AI companies like OpenAI and Anthropic will remain a critical factor to monitor, given their potential to impact the broader AI ecosystem and hyperscaler backlogs.
