India's tech start-ups are setting the public markets ablaze, but at what cost? Valuations are skyrocketing, and while early investors are cashing in, new shareholders might be left holding the bag. This week alone, two high-profile unicorns—Lenskart and Groww—made their stock market debuts, with Pine Labs set to follow. But here's where it gets controversial: despite mind-boggling valuations, these companies are attracting record demand. Lenskart, led by a Shark Tank India celebrity, saw its $821 million share offering sell out in hours, even as its market debut wobbled. Groww, backed by Microsoft CEO Satya Nadella, received 17 times more investor demand than available shares. This frenzy isn’t isolated—it’s part of a broader IPO boom, with 43 start-ups going public this year, up from just 8 in 2020. Yet, the question lingers: are these valuations sustainable, or are we witnessing a bubble? Experts argue this surge signals a maturing ecosystem, giving early investors an exit after a brutal funding winter. But this is the part most people miss: while early backers profit, retail investors often face slim chances of post-IPO gains. Shailendra Singh of PeakXV Partners credits better regulation and diverse market participants for the robust demand, but admits valuations are 'structurally high.' He urges founders to price shares responsibly, though he doesn’t believe all IPOs are overpriced. Meanwhile, Anand Daniel of Accel highlights a shift toward profitability and governance in today’s listings. Neha Singh of Tracxn notes fewer start-ups are failing, as founders prioritize sustainability over reckless growth. Yet, private equity funding remains below Covid-era peaks, suggesting a more cautious approach. So, is this boom a sign of progress or a warning of excess? And will the momentum last into 2026? One thing’s clear: the stakes are high, and the debate is far from over. What do you think? Are these IPOs a golden opportunity or a risky gamble? Share your thoughts below!
