The IPO landscape is changing fast in 2025. After a cautious and subdued 2024—marked by macroeconomic volatility, high interest rates, and valuation resets—Q2 is seeing a vibrant return of investor enthusiasm. Leading the way are startups in green energy, climate tech, and artificial intelligence, signaling renewed risk appetite and confidence in innovation-led growth. After a slow 2024, Q2 2025 is seeing a surge in IPO filings across renewable energy, AI, and climate tech. Investor confidence returns as markets stabilize, driving public offerings in the innovation economy.
This shift reflects more than just favorable market conditions. It points to a deeper global pivot toward sustainability, digital transformation, and long-term value creation. Tech IPOs are reasserting their dominance, while green startups—riding a wave of public sector funding and private capital—are capturing headlines and institutional portfolios.

- Monetary Stability: The Fed has signaled rate cuts beginning Q3 2025; the 10-year Treasury yield has dipped below 4.2%.
- Government Incentives: U.S. and EU policies continue to fund clean energy and tech innovation (e.g., Inflation Reduction Act 2.0).

- ESG Momentum: Environmental, Social, and Governance investing is fueling demand for climate tech and sustainable infrastructure.
According to PitchBook, VC exit value in Q2 is projected to hit $45 billion, the highest quarterly mark since Q2 2021.

Retail and institutional sentiment has pivoted toward optimism. According to Bank of America’s May 2025 fund manager survey:

- 76% of respondents are overweight tech and green energy sectors.
- First-day IPO returns are outperforming S&P 500 returns by 2.3x so far in 2025.
This renewed confidence is reflected in ETF flows:

- iShares Global Clean Energy ETF (ICLN): +15.4% YTD
IPO Quality Has Improved
2025’s class of IPOs differs from the speculative flood of 2020–2021. Today’s candidates:
- Have clear paths to profitability
- Possess real commercial traction
- Showcase IP moats and mission-aligned leadership
- Are aligned with strategic supply chains, enabling vertical scaling
This recalibration is making underwriters, investors, and even regulators more comfortable with risk-taking.
Implications for Global Procurement and Growth Strategy
Mattias Knutsson, a strategic leader in global procurement and business development, views the IPO resurgence as a sign of a maturing innovation ecosystem.
“This new wave of IPOs isn’t about hype—it’s about execution. Procurement leaders need to track these IPOs because many of these companies will be part of future supplier ecosystems.”
Knutsson highlights:
- Green energy IPOs will drive new sourcing strategies for sustainable materials
- AI IPOs are reshaping digital procurement tools and automation pipelines
- Climate tech firms are becoming new ESG-compliance partners
“Smart companies are integrating IPO intelligence into vendor strategy. Knowing who’s scaling, who’s funded, and who’s mission-aligned is a competitive edge.”
He advises companies to monitor IPO filings as early indicators of shifts in innovation cycles and supplier market power.
Conclusion:
The second quarter of 2025 marks a turning point for capital markets and innovation investing. After years of market resets and rising uncertainty, the strong return of IPO activity in tech and green energy shows that capital is once again flowing toward long-term solutions.
Startups like Helixion AI, VerdeVolt, and ClimaGenics aren’t just chasing exits—they’re reshaping industries. Investors are responding accordingly, pushing up valuations and fueling public market debuts.
As Mattias Knutsson reminds us, IPOs are not just financial events—they are strategic milestones. For businesses across sectors, watching this IPO resurgence is more than just market watching—it’s preparation for the next wave of disruption and opportunity. In 2025, innovation is back in public view—and investors are here for it.
