India’s IPO market is on fire. In FY25 alone, companies raised a staggering ₹4.3 lakh crore through public offerings, with another ₹1.4 lakh crore in the pipeline. Over 13 crore investors are now part of India’s capital markets — roughly 9% of the country’s entire population. That’s an extraordinary surge.
.
Between the moment IPO shares are allotted and the day those shares officially debut on the stock exchange, an informal, unregulated marketplace quietly thrives. Shares are bought and sold through word-of-mouth, WhatsApp groups, and unofficial brokers . The Grey Market Premium (GMP) has become a cocktail party talking point, yet it operates entirely outside regulatory view.
SEBI wants to change that.
What Is SEBI Proposing?
At the FICCI Capital Markets Conference in August 2025, SEBI Chairman Tuhin Kanta Pandey floated a compelling idea: a formally regulated “when-listed” or “to-be-listed” trading platform. The concept is simple but significant — allow investors to legally trade IPO-allotted shares in the window between allotment and the company’s official market debut, under SEBI’s oversight, through stock exchanges.
The Chairman was careful to frame this as a conceptual signal, not a done deal. “This is only in principle with what I’m stating,” he noted. But signals from a market regulator of SEBI’s stature are never accidental. This is a clear invitation to debate, explore, and build.
Why Does the Grey Market Exist at All?
The grey market fills a genuine need. After IPO allotment is done but before listing day, investors are in regulatory limbo. They own shares on paper but cannot trade them on any official exchange. For those who desperately need liquidity — or for those who smell a listing day windfall and want to lock in gains early — the grey market is the only option.
The challenge is that the grey market remains largely unregulated. Transactions are often informal, settlements rely heavily on mutual trust, and there is typically no depository transfer, broker audit trail, or direct SEBI oversight. In cases where a counterparty defaults or an IPO is delayed or shelved, investors may have limited formal recourse.
This is where structured grey-market platforms like ours at Altius Investech stands apart. By working only with verified counterparties, maintaining clear documentation, and following a process-driven settlement framework, platforms like ours aim to significantly reduce execution and counterparty risk. While grey-market investing always carries risk, participating through a reputed, transparent platform provides a far safer alternative to informal, off-market deals.
What a Regulated Platform Would Look Like
While details are still conceptual, the broad contours of a regulated “when-listed” platform would likely involve:
Legal, exchange-backed trading — Shares between allotment and listing could be traded on official stock exchange infrastructure, making deals traceable and settlement-guaranteed.
Disclosure requirements — Companies approaching listing would need to meet certain disclosure thresholds, giving traders access to reliable information before they transact.
Broker and depository safeguards — With SEBI-registered intermediaries involved, the risk of informal cash deals gone wrong would diminish significantly.
Private platforms like ours already offer pre-IPO share trading in a semi-structured way, but SEBI’s version would be the first truly official and regulated framework.
The Risks Worth Watching
This isn’t without its complications. SEBI-registered analysts and market observers have flagged a few concerns worth taking seriously.
First, the risk of listing delays or cancellations doesn’t disappear. If an investor buys shares on a “when-listed” platform and the company’s IPO is subsequently deferred or cancelled, those shares become illiquid and potentially worthless. The safety net of a formal platform doesn’t eliminate the underlying business risk.
Second, there is legitimate worry about price manipulation and information exploitation. Sophisticated market participants — institutional investors, anchor allottees, insiders — will always have informational edges over retail traders in this pre-listing phase. Without very tight insider trading and front-running regulations applied specifically to this window, a formal platform could become a new arena for the same old advantages.
Third, moving grey market activity into a formal setting could, counterintuitively, legitimize speculative excess if not managed carefully. SEBI would need strong circuit breakers, position limits, and surveillance mechanisms from day one.
The Bigger Picture: SEBI’s Regulatory Evolution
This proposal fits neatly into SEBI’s broader trajectory under Chairman Tuhin Kanta Pandey. The regulator has also been overhauling Portfolio Management Services (PMS) regulations, restricting mutual funds from participating in pre-IPO placements, tightening anchor investor lock-in periods, and cracking down on unregistered finfluencers.
The pattern is consistent: SEBI is methodically bringing informal or loosely regulated activity into formal frameworks, improving transparency, and raising the bar for investor protection.
The “when-listed” platform idea is the most ambitious step yet in this direction. It acknowledges that you cannot simply ban human behavior — traders will always seek liquidity — and instead channels that behavior into supervised structures.
What This Means for You as an Investor
If this platform eventually materializes, the implications are real and significant for everyday investors:
- You will have a legal way to exit your IPO allotment early if you need liquidity before listing.
- You will have formal redress if something goes wrong in a transaction.
- The GMP, while unlikely to disappear overnight, will lose its mystique and credibility as an informal benchmark.
For long-term investors, this also means a richer, more transparent signal about how the market truly values a company before it officially joins the exchange ecosystem.
Conclusion: A Bold Signal, A Necessary Debate
SEBI’s willingness to even examine limited oversight in the to-be-listed market is itself a milestone. It signals regulatory maturity — a recognition that India’s capital markets have grown too large and too consequential to leave corners of investor activity unmonitored.
The road from concept to implementation will be long. Consultations with exchanges, depositories, intermediaries, and the public will be needed. The risks around manipulation, cancellation, and disclosure adequacy must be resolved thoughtfully.
But if done right, a regulated “when-listed” platform could be one of the most meaningful structural upgrades India’s IPO ecosystem has seen in years. It’s a conversation worth having — and SEBI has officially started it.
