The Short Version
On August 10, 2026, NSE filed an addendum to its DRHP splitting SBI's 24,750,000-share OFS allocation between SBI (15,969,410 shares) and its wholly owned subsidiary, SBI Capital Markets Limited (8,780,590 shares), now added as a new selling shareholder. The trigger is Regulation 21A of the SEBI Merchant Bankers Regulations, which restricts a lead manager's role to marketing once it becomes a seller in its own issue, and SBI Capital Markets is one of NSE's nineteen book running lead managers. The filing also discloses something more interesting than the mechanics: SBI Capital Markets' certified cost basis on these shares is Rs 0.38 apiece, against a desk price near Rs 1970 today. This is a structural filing, not a fundamentals event. It does not move our price call on its own.
The Filing, Read Straight
NSE's original DRHP, filed June 17, 2026, listed SBI as a selling shareholder offering up to 24,750,000 equity shares. On August 10, 2026, NSE's Company Secretary and Compliance Officer, Smt. Prajakta Powle, signed and filed an addendum to that DRHP. Two sentences carry the actual change.
By letter dated August 10, 2026, SBI informed NSE that its offer will now be made jointly with SBI Capital Markets Limited, its wholly owned subsidiary. SBI will offer up to 15,969,410 equity shares. SBI Capital Markets will offer up to 8,780,590 equity shares. Add the two together and you get 24,750,000, the exact figure from the original DRHP. NSE's Governing Board, in a resolution passed the same day, took note of SBI's letter and took on record a consent letter, also dated August 10, 2026, from SBI Capital Markets agreeing to participate as an additional selling shareholder.

Selling shareholder | June 17 DRHP (original) | August 10 addendum (revised) | Change |

SBI Capital Markets Limited | Not listed | Up to 8,780,590 shares | +8,780,590 shares (new) |
Combined SBI group total | 24,750,000 shares | 24,750,000 shares | No change |
Source : Addendum to NSE's Draft Red Herring Prospectus dated June 17, 2026, filed August 10, 2026. Figures cover only SBI's allocation as amended by this addendum; not the full list of NSE IPO selling shareholders.
Nothing about the total size of SBI's exit changed. What changed is who is doing the selling, and that detail is disclosed with dates precise enough to check: corporate approval for SBI's portion is dated May 12, 2026; for SBI Capital Markets, August 8, 2026; both consent letters, August 10, 2026, the same day as the addendum itself.
Why Split It At All : Regulation 21A
The addendum states its own reason, in NSE's words: "On account of the restrictions under Regulation 21A of the SEBI Merchant Bankers Regulations, SBI Capital Markets Limited, in its capacity as a book running lead manager to the Offer, will be involved only in the marketing of the Offer."
We checked Regulation 21A directly against SEBI's own text, not a secondary summary of it. It bars a merchant banker from lead-managing an issue if it is a promoter, director, or associate of the issuer, with one proviso: such a merchant banker may still be appointed if its role is limited to marketing the offer. SBI Capital Markets sits among NSE's nineteen book running lead managers, alongside Kotak Mahindra Capital, JM Financial, Morgan Stanley India, Citigroup Global Markets, and others. Once it also became a seller of NSE shares in its own right, that provision applied to it directly, and the addendum confirms the resulting marketing-only role rather than leaving it implied.
This is not unique to SBI. The same addendum discloses that Morgan Stanley India Company Private Limited and ICICI Securities Limited face the identical restriction, because their respective affiliates, MS Strategic (Mauritius) Limited and ICICI Lombard General Insurance Company Limited, are also selling shareholders in this offer. Three of nineteen lead managers on this IPO are boxed into marketing-only roles for the same structural reason. SBI Capital Markets is simply the latest.
The Cost Basis Nobody Is Talking About
The part of this filing worth reading twice is the certified acquisition cost, not the entity restructuring. Manian & Rao, Chartered Accountants, certified the following weighted average cost of acquisition (WACA) figures as part of the addendum, dated August 10, 2026: SBI's shares carry a WACA of Rs 0.80 each; SBI Capital Markets' carry a WACA of Rs 0.38 each. The latter traces largely to a 4:1 bonus issue on November 4, 2024 (record date November 2, 2024), under which SBI Capital Markets received 85,800,000 additional shares at nil cost.
Against today's desk price of roughly Rs 1970, that WACA implies a return of about 2,463x on the shares SBI itself is selling, and about 5,184x on the shares SBI Capital Markets is selling. Those are large multiples on paper, and they are a function of how early and how cheaply these entities acquired NSE shares, not a signal about what NSE is worth today. SBI Capital Markets' total disclosed holding in NSE is 107,250,000 shares; the 8,780,590 shares in this OFS represent about 8.2% of that holding, and roughly 0.36% of NSE's total outstanding shares. This is a partial, not a full, exit.

The Desk View
Our live desk price for NSE is Rs 1970, as of today, August 14, 2026.
This filing is a change in who is selling, not a change in what NSE is worth. It does not touch revenue, profit, or the company's own balance sheet, and it does not alter the total size of the OFS. On its own, it does not move our price. What it is worth watching is liquidity: SBI Capital Markets' 8,780,590 shares add roughly 0.36% of NSE's outstanding shares into the seller pool via a lead manager that will now be doing nothing but marketing this deal, on shares it holds at a cost so far below any plausible listing price that its economics are effectively indifferent to where the IPO prices. That is not a red flag by itself, cost-basis gaps of this size are ordinary for very early holders of any company approaching an IPO, but it does mean this particular seller has no price sensitivity, which is worth knowing if you are trying to read demand signals into the OFS book once bidding opens. The one thing that would change our view is if further addenda show more legacy, near-zero-cost holders adding to the sell side beyond what is already disclosed in the DRHP.
FAQs
What is the NSE unlisted share price today?
Our live desk price is Rs 1970 as of August 14, 2026. This price moves with company performance, demand and supply on the unlisted market, and IPO-related developments, so treat any number quoted elsewhere as unconfirmed until you check with the desk directly.
Why did SBI split its NSE stake sale with SBI Capital Markets?
Because SBI Capital Markets, a wholly owned SBI subsidiary, is also one of NSE's book running lead managers on this IPO. Once it became a seller of NSE shares itself, Regulation 21A of the SEBI Merchant Bankers Regulations required it to step back to a marketing-only role in the offer, a restriction NSE discloses directly in the August 10, 2026 addendum.
Did the total size of SBI's stake sale change?
No. SBI's original allocation of 24,750,000 shares is unchanged in total. It is now split between SBI (15,969,410 shares) and SBI Capital Markets (8,780,590 shares), which sum to the same original figure.
What did SBI Capital Markets pay for its NSE shares?
Its certified weighted average cost of acquisition is Rs 0.38 per share, largely reflecting a nil-cost 4:1 bonus share issue in November 2024. SBI's own cost basis is Rs 0.80 per share.
Does this addendum change NSE's IPO valuation or timeline?
Not directly. It is a shareholder-and-structuring disclosure, not a change to offer size, pricing, or the DRHP's underlying business or financial disclosures.
What We Can And Cannot Stand Behind
Primary-sourced and confirmed : The share split figures, dates, board resolution details, Regulation 21A rationale, and all weighted average cost of acquisition figures in this note are drawn directly from NSE's addendum to the DRHP, filed August 10, 2026 and signed by the Company Secretary and Compliance Officer. The text of Regulation 21A was independently verified against SEBI's own Merchant Bankers Regulations, not a secondary summary.
Derived, not disclosed : The implied return multiples (~2,463x and ~5,184x), the estimated OFS value in rupees (~Rs 3,146 crore and ~Rs 1,730 crore), and the percentage figures (8.2% of SBI Capital Markets' own holding, 0.36% of NSE's total shares) are our calculations, built on disclosed figures and our own live desk price, which moves.
Unconfirmed and flagged : The addendum's Annexure B-1 table on secondary transactions includes several 2007-2008 share transfers by SBI Capital Markets at per-share prices from an earlier capital structure; we have not reconciled these against subsequent bonus issues or splits, and have left them out of this note as a result, since we could not state them with confidence.
