SpaceX's IPO and US-Iran peace signals boost US stocks: How do institutional investors view the shift in capital flows?

SpaceX Listing and US-Iran Peace Signals Drive US Stock Gains: How Do Institutional Investors View Capital Flow Shifts?

Introduction

On June 12, 2026, all three major US stock indices rose, with the S&P 500 up 0.5%, the Nasdaq 100 up 0.6%, and the Dow Jones Industrial Average up 0.7%. The two main factors driving the market upward were SpaceX's strong debut on the Nasdaq and positive signals that a US-Iran peace agreement is close. For global institutional investors, these two events not only affect short-term risk appetite but may also trigger structural changes in medium- to long-term capital flows.

Market Background

• Market sentiment was boosted by multiple factors on the day:
• SpaceX IPO: The company opened at $150 per share (above its IPO price of $135) and closed at around $161, a gain of 19%. Its founder Elon Musk holds approximately 40% of the shares but has about 85% voting control. SpaceX's listing made him the world's first trillionaire.
• US-Iran Peace Progress: Pakistani Prime Minister Sharif announced that a "final agreement text has been reached," and Iranian Foreign Minister Araghchi stated that peace has "never been so close." Bloomberg reported that the agreement could be signed in Switzerland as early as Sunday (June 14).
• Sector Performance: Materials and financial sectors led gains, followed by technology and consumer sectors. The semiconductor ETF (SMH) rose 1.7%.
• Economic Environment: No major economic data was released on the day, but market expectations for the Fed's interest rate path remained stable. The 10-year US Treasury yield edged lower, reflecting reduced safe-haven demand.

Current Capital Flows

• From trading on the day and recent dynamics, several changes in capital flows can be observed:1. IPO Market Regains Attention: SpaceX's successful debut marks a potential revival of the long-dormant IPO market. SuRo Capital CEO Mark Klein noted, "The IPO parade has become a stampede," and SpaceX will serve as a bellwether. A surge of capital into a few star companies may crowd out the listing window for others.
• 2. Energy Sector Divergence: Shell (SHEL) is reportedly considering selling offshore wind assets worth over $10 billion, continuing its shift from renewable energy to higher-return fossil fuel operations. ExxonMobil (XOM) is studying the acquisition of Australia's Woodside Energy Group. This indicates that traditional energy giants are refocusing on oil and gas, while clean energy assets face capital outflow pressure.
• 3. Accelerated Tech Industry Consolidation: Streaming platform Roku (ROKU) has reportedly been in talks for a sale, and Microsoft's Xbox is considering a spin-off, reflecting tech giants restructuring under profit pressure and potentially triggering more M&A activity.
• 4. Lower Geopolitical Risk Premium: If a U.S.-Iran peace deal is reached, it would reduce Middle East geopolitical risks, leading to a same-day drop in crude oil prices and a shift of capital from safe-haven assets (e.g., gold, Treasury bonds) to risk assets (e.g., stocks, emerging markets).- Uncertainty of the Peace Agreement: Trump warned Iran on Truth Social to "better act fast," indicating the deal could still break down. Retail investors on Stocktwits have a bearish sentiment toward SPY, DIA, and QQQ, questioning the durability of the ceasefire.
• Sustainability of the IPO Boom: The explosive popularity of SpaceX may attract a flood of companies to go public, but if the quality of subsequent companies is poor, the market could cool quickly. Mark Klein also noted that many companies will wait to see how SpaceX performs before moving forward.
• Valuation Risk: Currently, the S&P 500's P/E ratio is at a historical high (around 22x), with tech stocks being particularly expensive. If interest rate expectations turn hawkish, high-valuation sectors will face adjustments.
• Uncertainty in Energy Transition Policy: Whether the Trump administration continues clean energy subsidies will affect the pace of asset disposals by companies like Shell. Additionally, if U.S. sanctions on Iran are lifted, Iranian crude oil could return to the market, further depressing oil prices and impacting U.S. shale oil companies.
