The Securities and Exchange Board of India (SEBI) has approved a series of major reforms to IPO norms and market regulations aimed at making it easier for very large companies to go public, relaxing minimum public offer and shareholding timelines, and strengthening governance of market infrastructure institutions. The changes include eased dilution requirements for IPOs of companies with very large market capitalizations, extended timelines for minimum public shareholding (MPS), expanded anchor investor categories, and a single-window onboarding facility for certain foreign portfolio investors (FPIs). These reforms are intended to boost domestic listings of large companies, enhance foreign investor access, streamline intermediaries’ due diligence, and improve transparency and market discipline. Implementation details and specific updated regulations are expected soon via SEBI circulars.

SEBI Board Approves Sweeping IPO and Market Norm Reforms to Boost Large Listings and Investor Access

SEBI Board eases IPO norms for very large companies, extends timelines, expands anchor investor base, and streamlines foreign investor onboarding.

The Securities and Exchange Board of India (SEBI) in its 211th Board meeting on September 12, 2025, approved a comprehensive set of reforms aimed at making India’s capital markets more accessible and efficient for large issuers and investors alike. The changes include relaxed minimum public offer (MPO) and minimum public shareholding (MPS) norms for mega IPOs, an increased anchor investor allocation with widened eligibility, a single-window clearance system for certain foreign portfolio investors (FPIs), as well as strengthened governance norms for market infrastructure institutions. These reforms are expected to facilitate large domestic IPOs that previously faced hurdles in meeting upfront dilution requirements, while also enhancing market governance and investor participation. Detailed operational guidelines will be announced soon through regulatory circulars.

What’s New

Relaxation in Minimum Public Offer and Minimum Public Shareholding norms for very large IPO issuers based on post-issue market capitalization.

Extended timelines to meet minimum public shareholding: from 3 years to up to 10 years depending on issuer size.

Anchor investor portion increased from one-third to 40% of the issue size.

Inclusion of life insurers and pension funds in the reserved category for anchor investor allocation.

Single-window onboarding and registration facility for ‘low-risk’ foreign portfolio investors to simplify access.

Strengthened governance in market infrastructure institutions with appointment of two executive directors overseeing operations and regulatory compliance.

Focus on improved disclosures, due diligence tightening, and accelerated issue and listing timelines (including potential T+1 or T+0 targets).

Relaxed norms encourage large Indian corporate giants, such as Reliance Jio and NSE, to list domestically rather than overseas.

Enhanced transparency and risk management measures mandated for intermediaries and market infrastructure.

Deep Dive — IPO Reforms

Disclosure & Risk

Old Rule: Strict upfront disclosure requirements but limited flexibility in financial track-record and key performance indicators (KPIs) disclosures for mega IPOs.
New Rule: SEBI has mandated clearer, more structured disclosures on KPIs and risk factors tailored for large issuers, including expanded related-party transaction transparency and detailed use-of-proceeds specifications.
Who’s Affected: Issuers, investors, intermediaries.
Rationale: To enhance investor protection by providing clearer, timely data and reduce information asymmetry in large IPOs.
Immediate Impact: Investors will receive richer risk and performance data; issuers must prepare enhanced disclosures prior to filing.

Pricing & Allocation

Old Rule: Minimum public offer thresholds rigidly set based on fixed percentage or amount causing liquidity strain for mega IPOs. Anchor investor portion capped at ~33%.
New Rule: MPO thresholds lowered for large issuers based on both absolute size and % of post-issue market cap (e.g., ₹15,000 crore plus 1% post-issue mcap for >₹5 lakh crore mcap companies). Anchor investor allocation raised to 40%, with extended eligibility to life insurers and pension funds.
Who’s Affected: Issuers, anchor investors, HNIs, NIIs, retail investors.
Rationale: To reduce upfront dilution pressure, ease pricing and allocation for mega IPOs, and diversify anchor investor category for greater demand stability.
Immediate Impact: Large issuers can come to market with lower public offer dilution; anchors gain increased allocation opportunities.

Promoter/Shareholder Lock-ins

Old Rule: 3-year lock-in for promoter shares post-IPO; strict OFS guardrails.
New Rule: Extended phased lock-in timelines for minimum public shareholding — up to 5-10 years depending on issuer size and public float level at listing (e.g., 25% MPS to be achieved in 5-10 years versus 3 earlier).
Who’s Affected: Promoters, PE/VC shareholders.
Rationale: To accommodate gradual liquidity absorption for large issuers, preventing sharp market supply shocks.
Immediate Impact: Promoters have additional time to comply, reducing forced sell-offs at IPO.

Intermediaries (BRLM & Due Diligence)

Old Rule: Existing BRLM obligations mandated thorough due diligence but with limited focus on specific large-issuer risks.
New Rule: Tighter due diligence and monitoring enhanced for book running lead managers covering disclosures, track records, and use-of-proceeds verifications.
Who’s Affected: Merchant bankers, industry stakeholders.
Rationale: To strengthen issuance quality and investor confidence for mega IPOs.
Immediate Impact: Increased due diligence workload; better quality issuer assessment.

Timelines & Listing Processes

Old Rule: Refunds and listing processes followed T+2 or T+3 timelines.
New Rule: SEBI aims for accelerated timelines including potential T+1 or even T+0 settlements for top stocks, faster refund processes, and digital IPO application handling improvements.
Who’s Affected: Issuers, investors, stock exchanges.
Rationale: Align with global best practices to improve liquidity and market efficiency.
Immediate Impact: Faster IPO completion and improved post-listing market activity.

Implementation & Timelines

Transition provisions and grandfathering details for already filed DRHPs are awaited in SEBI circulars.

Who Wins / Who Loses

• Winners: Very large issuers (e.g., Reliance Jio, NSE) relieved of upfront dilution pressure; anchor investors including life insurers and pension funds; FPIs via streamlined registration; retail investors benefit from improved disclosures.
• Losers: May include some existing intermediary roles needing to adapt to tighter due diligence; certain smaller issuers unaffected but facing higher competition for investor wallet.
• Neutral: Promoters gain flexibility but must meet longer lock-in commitments.

Comparative Lens

India’s flexible phased approach to minimum public shareholding for mega IPOs contrasts with the US where IPO lock-ins and dilution norms are less prescriptive, and with Singapore and the UK which also offer anchor investor frameworks but not always extended timelines. The increased anchor allocation to 40% aligns with global trends of seeking stability via marquee investors.

Market & Deal Pipeline Impact

The relaxed requirements and extended timelines are expected to unblock mega deals that had been deferred due to stringent upfront dilution needs. Companies like Reliance Jio and NSE could list domestically sooner, improving the IPO pipeline and liquidity. Valuation pressure from forced large public offers will ease, potentially stabilizing subscription patterns. The focus on better anchor participation and foreign investor access should improve aftermarket stability.

Expert Commentary

“This resets due diligence incentives by enhancing focus on disclosures related to large issuers’ risk and capital use,” said a senior investment banker advising mega IPOs.
“Lock-in tweaks should reduce day-1 froth by allowing gradual market supply and better price discovery,” said an equity strategist at a leading brokerage.
“Disclosure clarity on KPIs and use-of-proceeds will help retail investors assess issuer quality more confidently,” said a securities lawyer specializing in capital markets compliance.

Risks & Open Questions

• Several rules are “subject to circular” and operational guidelines are pending.
• Grandfathering conditions for DRHPs already filed are not yet disclosed.
• Potential unintended effects on secondary market supply and volatility remain to be monitored.
• Details of new FPI single-window onboarding criteria are awaited.

Actionable Checklists

For Issuers/Bankers:

• Validate and update KPI, related-party, and use-of-proceeds disclosures.
• Recalculate dilution and minimum public offer requirements based on new thresholds.
• Revise anchor investor strategies to include life insurers and pension funds.
• Prepare for extended MPS timelines and updated lock-in commitments.
• Monitor SEBI circulars and stock exchange notices for operational timelines.

For Retail/HNI Investors:

• Review new disclosures on KPIs and risk factors in IPO documents.
• Check anchor investor composition and lock-in schedules.
• Assess implications of extended minimum public shareholding timelines on liquidity.
• Watch for red flags in “Risks” sections regarding promoter sell-downs and use-of-proceeds.

SEBI’s landmark reforms represent a strategic balancing act to unlock India’s mega IPO potential by easing upfront dilution and extending timelines without compromising investor protection. Combined with enhanced foreign investor facilitation and governance tightening at market infrastructure firms, these changes mark a significant evolution for India’s capital markets. Over the next 6–12 months, this framework is poised to catalyze blockbuster listings, deepen market participation, and solidify India’s positioning as a preferred equity destination.
