BSE & MCX Drop 5% on NSE IPO Valuation Threat

BSE and MCX Slide as NSE IPO Reshapes Exchange Sector Pricing Shares of [BSE](/stock/BSE) and [MCX](/stock/MCX) fell as much as 5% in Thursday's session after Jefferies flagged something the market had been slow to price: NSE's anticipated IPO, targeting a valuation above ₹5 trillion through a ₹30,000 crore OFS, isn't just a capital markets event. It's a competitive signal. And investors in the listed exchange peers are only now being forced to sit with it. NSE's numbers are hard to argue with.

MCX's situation is different. Its core business is commodity derivatives — crude oil, gold, silver, base metals — where it holds a dominant position that has nothing to do with NSE's equity franchise. The 5% sell-off in MCX looks like sentiment contagion, not fundamental repricing. That said, NSE has been building its commodity der...
