Space X + Open Ai + Anthropic collectively IPO in June, what impact will it have on US stocks? — from Chat gpt

If you assume these three companies conduct their IPOs around June 2026, the biggest impact on the U.S. stock market is not "gains or losses," but Liquidity Drain.

Many analysts already believe these three companies could become the largest wave of tech IPOs in history.

Stage 1: Pre-IPO (Easiest Liquidity Drain)

Institutions, in order to participate in IPO subscriptions, often sell part of their existing holdings in advance to raise cash.

The main targets for selling are likely:

• AI concept stocks
• Semiconductor stocks
• Large-cap tech stocks
• Growth stock ETFs

For example:

• NVIDIA
• Microsoft
• AMD
• Palantir

Therefore, in the weeks before the IPOs, the Nasdaq might experience:

• Index volatility
• The AI sector underperforming the broader market
• High-valuation growth stocks correcting

This is the so-called "liquidity drain effect."

Stage 2: IPO Day

If the offerings are successful and subscriptions are hot:

The market will gain new core assets.

Especially SpaceX.

Current market expectations place SpaceX's valuation potentially in the range of $1.7 to $2 trillion, a single entity size already approaching that of U.S. stock market super heavyweights.

Thus:

A lot of capital will shift from:

• ETFs
• Hedge funds
• Sovereign wealth funds
• Retail investors

towards the IPO stocks.

In the short term:

IPOs rise, old AI stocks fall.

Stage 3: 3~12 Months Post-Listing

This is the most critical phase.

If the three companies are smoothly included in indices:

• S&P 500
• Nasdaq 100

then passive funds must buy. Some analysis suggests large IPOs could lead to index weight reallocation, triggering hundreds of billions of dollars in fund rebalancing.

The result could be:

• Further increase in the AI sector's weight
• Continued rise in U.S. stock market concentration
• The "Magnificent Seven" era becoming the "Top Ten" era

Impact on Different Sectors

Because capital will further concentrate towards super giants.

Extreme Scenario

If the combined valuation of the three companies approaches:

• SpaceX: $1.7~2 trillion
• OpenAI: $0.8~1 trillion
• Anthropic: $0.8~1 trillion

Then the added market cap could exceed $3.5 trillion.

This is equivalent to recreating a scale close to the top few weighted sectors of the entire NASDAQ Composite.

Historically, only IPOs like:

• Alibaba Group
• Saudi Aramco

have come close to this level of influence.

My Judgment

If the three truly list in the same quarter, concentrated:

1. Short-term (1~3 months) slightly bearish for U.S. stocks — liquidity is drained.
2. Medium-term (3~12 months) slightly bullish for the Nasdaq — new leaders are born.
3. Bearish for small/mid-caps and traditional industries — capital further concentrates towards AI and super platforms.
4. The most hurt might not be tech stocks, but the neglected small-cap growth stocks, as they most easily become the "funding source."

Therefore, this is more like a large-scale repricing of the U.S. capital market, not just the IPOs of three companies.
