Three Mega IPOs Line Up: $4 Trillion New Market Value Tests US Stock Liquidity

l Three tech heavyweights gear up for blockbuster listings, with combined valuation nearing $4 trillion

l Massive capital raising will strain market liquidity and trigger reshuffles across existing tech stocks

l Looming lock-up expirations and stretched valuations cast long-term risks over the IPO rally

OpenAI has confidentially filed for an IPO with the SEC, officially joining an unprecedented wave of blockbuster listings. Together with SpaceX and Anthropic, the three tech giants carry a combined valuation of nearly $4 trillion, set to hit public markets in the coming months.

Core Business Profiles

SpaceX will debut on June 12 at an offer price of $135 per share, valuing the firm at $1.77 trillion with planned proceeds of $750 billion, smashing global IPO records. Merged with xAI, it pitches a combined space and artificial intelligence narrative, yet posted roughly $19 billion in revenue and a net loss of nearly $5 billion in 2025.

Anthropic submitted confidential IPO paperwork on June 1 and is now valued at $965 billion, edging past OpenAI. The firm forecasts its first operating profit of $559 million in Q2 2026, with annualized revenue topping $44 billion.

OpenAI boasts a valuation of $852 billion and targets a listing as early as this autumn. Its ChatGPT has over 900 million weekly active users and annualized revenue exceeding $20 billion. Persistent heavy spending continues to weigh on profitability.

Triple Pressure on Market Liquidity

The three firms are expected to raise over $200 billion in total. Fund managers now hold just 3.9% of assets in cash, near historic lows, leaving limited spare capital. JPMorgan estimates passive funds may have to offload $95 billion worth of stakes in major tech names just to make room for SpaceX.

Nasdaq has shortened the index inclusion window for large IPOs to 15 trading days and applied preferential weighting terms. Trillions in passive index funds will be forced to buy the new shares at elevated levels. Historical data shows most large IPOs deliver negative returns six and twelve months after listing, with deep drawdowns common within the first year.

Lock-up expirations pose another major risk. Only around 4% of SpaceX shares will trade freely at the debut. Insiders can sell portions of their holdings in phases after the first quarterly report, while around half of Elon Musk’s shares face a 366-day trading ban. Research from University of Florida’s Jay Ritter reveals companies with a price-to-sales ratio above 40x have underperformed the broader market by 58 percentage points over three years. SpaceX’s multiple stands close to 100x.

With massive capital supply, forced selling of existing stocks and looming lock-up unlocks, the true stress test for Wall Street lies ahead long after these high-profile IPOs start trading.
