IPO Window Widens: SPAC Resurgence and AI Giants Navigate Public Market Entry

Global Markets See Uptick in Public Offerings, But AI Leaders Face Unique Hurdles

The IPO market is experiencing a significant resurgence in 2024 and 2025, with Special Purpose Acquisition Companies (SPACs) making a notable comeback. This renewed activity is creating opportunities for companies across various sectors, particularly in artificial intelligence, to access public capital. However, the path to public listing for the world's largest AI companies is proving complex, challenging conventional expectations regarding their funding needs.

Market data indicates a robust increase in SPAC activity and traditional IPOs. "This year is shaping up to be the third busiest year for SPAC activity," according to a recent report, with 81 SPACs tracked in 2025 compared to 57 in the previous year. This resurgence is largely driven by retail investors and interest in high-growth sectors like quantum computing, space technology, and artificial intelligence. Regulatory adjustments in 2024, aimed at increasing transparency, have also contributed to a more stable environment for these alternative listing vehicles.

Despite the broader market's enthusiasm, skepticism remains regarding the public market potential of highly valued private AI firms. A social media post by "JT" highlighted this sentiment, stating, "> So SPACs are back and the IPO window is wide open for companies of every quality level, but a simple 10% IPO for the largest AI company in the world that closes its funding needs forever is beyond contemplation by the MSM (“wHErE wilL TheY gET dA $ frOM?”)." This tweet points to a perceived disconnect between market readiness and the unique financial structures and funding capacities of leading AI innovators.

Companies like OpenAI, valued at $86 billion, and Anthropic, at $18.4 billion, have raised billions in private funding, with OpenAI alone securing $10 billion from Microsoft. While OpenAI is considered "possibly the most anticipated AI IPO," its unique structure, governance, and substantial private capital present a long road to a public offering. Databricks, another AI and data giant, is planning an IPO for 2025 with an estimated $100 billion valuation, showcasing the immense scale of these companies.

The challenge for these AI powerhouses often lies not in a lack of capital, but in navigating complex governance, maintaining control, and demonstrating a clear path to sustained profitability that satisfies public market investors. Their "near-limitless private funding" allows them to delay IPOs, focusing on long-term growth and innovation without immediate public market pressures, which contrasts with smaller, less-funded entities eager to capitalize on the open IPO window.
