Jio Platforms' IPO timeline has accelerated following SEBI's final observations in late August and completed overseas roadshows led by Akash Ambani, with strong institutional interest supporting a potential $3.8 billion raise at a $143-146 billion enterprise valuation. The fresh-issue structure targets debt reduction at subsidiary Reliance Jio Infocomm while marking Reliance's first major listing since 2008. Final SEBI filing is slated for the week of October 12, with anchor book opening around October 19 and possible subscription from October 21-23 ahead of an end-of-month listing. Market-implied odds reflect this momentum, tempered by typical last-minute regulatory or market-condition risks that could shift the schedule.
