A Bullish Market Opens the Window
One of the simplest reasons for the rush is that the timing is right. Stock markets have shown remarkable strength, with the S&P 500 marking three consecutive years of gains and looking poised for a fourth. This sustained positive performance creates
what is known as an “IPO window”—a period where investor appetite for new stocks is high, and they are more willing to invest in newly public companies. This confidence makes it easier for companies to achieve higher valuations and successfully raise the capital they are looking for. After a sluggish period in 2022 and 2023, the market's rebound in 2025 and 2026 has provided the confidence needed for many companies to finally move forward with their listing plans.
The Artificial Intelligence Gold Rush
The intense investor interest in artificial intelligence is a massive catalyst. Several high-profile AI companies are among the most anticipated listings for the rest of the year. For instance, Anthropic, the company behind the Claude chatbot, is expected to launch a potentially record-breaking IPO. The race to dominate the AI space is incredibly expensive, requiring huge investments in research, development, and computing infrastructure. An IPO provides the enormous amount of capital needed to scale quickly and compete. This AI frenzy has a halo effect, boosting general market sentiment and encouraging companies from other sectors to also tap into the enthusiastic investor base.
Strategic Needs and Cashing Out
Beyond favourable market conditions, companies have pressing strategic reasons to raise funds now. An IPO is a primary way to secure large amounts of capital for various purposes: funding expansion, paying down debt, investing in research, or making acquisitions. For many of the companies lining up to go public in India, for example, the funds raised from a fresh issue of shares are earmarked for long-term working capital, inventory, or expansion. An IPO also provides a crucial opportunity for early investors, founders, and employees to achieve liquidity—meaning they can finally sell some of their shares and realise a return on their long-term investment. This is often referred to as an 'offer for sale' (OFS), where existing shareholders sell their stake to the public.
Who Is in the September Pipeline?
The list of companies expected to go public is diverse, spanning tech, retail, and finance. In the global market, all eyes are on potential blockbusters like AI firm Anthropic and the health-tech company Oura, which makes smart fitness-tracking rings. Fast-fashion giant SHEIN is targeting a major listing in Hong Kong. In India, the primary market is also set for a busy month with several companies launching their IPOs. These include Rays of Belief (operating as Mom's Belief), Deepa Jewellers, and Phychem Technologies, among others, all scheduled to open for subscription in late August or early September. This packed calendar shows a broad-based desire to tap public markets.
The Fear of a Closing Window
While conditions are good now, there's an underlying fear that this ideal window might not stay open for long. Economic and geopolitical uncertainty are ever-present risks. Factors like rising energy prices, future changes in interest rate policy, and the potential for market volatility could dampen investor sentiment. Companies and their bankers are aware that these windows can close as quickly as they open. This creates a sense of urgency to complete the offering while the market is receptive. The backlog of companies that have been waiting for years to go public is now rushing to the exit before conditions potentially shift for the worse.
