India imports a huge chunk of its natural gas. Somewhere between the tanker and your gas stove sits a small, quietly profitable company called the Indian Gas Exchange. It's about to go public — and it's already trading in the unlisted market. Here's the whole story, minus the jargon.
FIRST, A CONFESSION MOST EXPLAINERS SKIP
LNG, PNG, CNG and LPG are NOT four different gases. Three of them are the same gas wearing different costumes, and one is a total outsider.
Natural gas — mostly methane — is the actual commodity. Everything else is just a format:
LNG = natural gas chilled to −162°C into a liquid, so it ships across oceans. This is how India imports it.
RLNG = that LNG turned back into gas at a terminal, ready for pipelines. Same molecule.
PNG = piped natural gas, the same gas delivered to homes and factories by pipe. A delivery method.
CNG = compressed natural gas, the same gas squeezed into cylinders for your car. Also a format.
LPG is the odd one out — the red cooking cylinder (propane/butane), a refinery product. Nothing to do with natural gas, nothing to do with IGX.
So "how many gases trade on IGX?" — the honest answer is ONE. Natural gas. Sourced either from Indian fields (domestic gas) or imported as LNG and regasified into RLNG. That's it.
1. WHAT DOES IGX ACTUALLY DO?
Think of the stock market. Buyers and sellers meet on an exchange, a price gets discovered, the exchange takes a tiny fee per trade. It doesn't own the shares. It just runs the venue.
IGX is exactly that, but for natural gas. India's first and only authorised national gas exchange. Born in 2019 as a subsidiary of IEX (which runs India's biggest electricity exchange), licensed by the regulator PNGRB in December 2020.
Crucially: IGX never buys, sells, owns, or takes price risk on the gas. It provides the marketplace, the technology, the settlement plumbing — and charges a toll on the activity flowing through. Roughly ₹4–₹6 per unit (MMBtu) traded. It's a toll booth on India's gas highway.
2. HOW GAS TRAVELS FROM QATAR TO YOUR HOME
Most people picture this backwards. Trace it properly, using Petronet LNG (India's largest importer) buying from Qatar:
Qatar → Importer signs a long-term bilateral deal with QatarEnergy. Often 15–20 years. NO exchange here.
Ship + terminal → LNG sails to Dahej/Hazira/Kochi and is regasified into RLNG so it can enter pipelines.
IGX ← This is where IGX plays. Spare or spot RLNG gets offered on the exchange. A buyer grabs it at a transparent price.
The buyer → A city gas company, power plant, or fertiliser unit takes physical delivery at one of 19 delivery points.
Your home → The city gas company turns it into PNG for your kitchen or CNG for your car.
The key insight: the big Qatar import is NOT done on IGX. The bulk of India's gas still moves through long-term bilateral contracts — private, off-exchange. That's the "other mode."
IGX enters as the flexible, spot marketplace layered on top. Surplus gas gets sold on IGX. A buyer who needs gas THIS WEEK — without a 20-year contract — buys on IGX. It's the difference between a long lease and a hotel room.
3. WHY WOULD ANYONE BUY GAS ON AN EXCHANGE?
For decades, Indian buyers negotiated one-to-one. Slow, opaque, loaded with punishing "take-or-pay" penalties. IGX flipped that:
Transparent price discovery — IGX built GIXI (Gas Index of India), the country's first spot-gas benchmark from actual delivered trades. You see the market rate instead of guessing.
Flexibility without lock-in — top up on demand (spot) or plan ahead (forward, up to six months) instead of over-committing.
Anonymity + counterparty guarantee — you don't need to trust the other party. The exchange clears, settles, and guarantees the trade.
The flywheel: more participants → more trades → better price discovery → attracts even more participants. IGX is early in that loop.
4. THE TAM — HOW BIG CAN THIS GET?
Not all of India's gas can go on an exchange. Three buckets:
APM / administered gas → CANNOT trade (government-priced, allocated to fertiliser & city gas first)
Domestic "free-market" gas → CAN trade, but capped
Imported LNG / RLNG → CAN trade (spot & surplus; most stays in long-term deals)
The catch on domestic gas: a 2021 rule lets producers sell only the higher of 500 MMSCM or 10% of a field's annual production through exchanges. IGX has asked to raise/scrap this; projections assume it rises to 30% from FY27. (An assumption, not a done deal.)
The opportunity:
Metric | FY26 | FY30 (est.) |
|---|---|---|
| India's gas consumption | 68.5 BCM | 108.4 BCM |
| IGX addressable market (TAM) | 16.4 BCM | ~40 BCM |
| IGX's actual volume | 1.94 BCM | ~6.8 BCM |
| IGX share of India's gas use | ~2.8% | ~6.3% |
In one line: IGX touches under 3% of India's gas today, inside a market that's already ~24% addressable. The TAM is projected to grow ~25% a year — double the pace of overall gas demand. That gap between 3% and 24% is the entire thesis.
Why more LNG imports = more fuel for IGX: India's fields can't keep up, so the shortfall is met by imported LNG. And imported LNG is exactly the flexible, spot-friendly gas that lands on exchanges. More LNG = more spot cargoes = more volume through IGX's toll booth. A tailwind, not a threat.
5. THREE YEARS OF FINANCIALS (₹ crore)
Particulars | FY24 | FY25 | FY26 |
|---|---|---|---|
| Revenue from operations | 34.8 | 48.8 | 61.0 (+25%) |
| Total income (incl. treasury) | 54.6 | 69.1 | 84.8 |
| EBITDA | 33.9 | 46.1 | 58.6 |
| Profit before tax | 30.7 | 40.3 | 55.8 |
| Profit after tax | 23.0 | 30.8 | 42.0 (+36%) |
| EPS (₹) | 3.12 | 4.17 | 5.68 |
Three takeaways:
Profits grew faster than revenue. PAT nearly doubled in two years while costs barely moved (expenses +under 1% in FY26). The magic of an exchange — once built, extra volume drops almost straight to the bottom line. Adjusted EBITDA margin climbed 41% → 53% → 57%.
A big chunk of "profit" is treasury income. Total income (₹84.8 cr) far exceeds operating revenue (₹61 cr). That ~₹24 cr gap is interest and investment gains on IGX's cash pile — ~28% of total income. Real money, but lower quality than trading fees.
It's tiny. The entire exchange did just 1,924 trades in all of FY26. ₹42 cr profit is a small-cap. This is a bet on a category that barely exists yet.
6. WHY IPO NOW, WHEN IGX IS STILL SMALL?
The sharpest question, with an un-hype-y answer: IEX isn't choosing to sell. It's being forced to.
Gas exchange regulations cap any non-member shareholder at 25% ownership, with excess to be sold within five years of the licence. IGX got its licence December 2020, so the clock ran out. After an extension, IEX must cut below 25% by 31 December 2026.
What "forced OFS" means for you:
100% Offer for Sale. Every rupee goes to IEX, not to IGX. The company raises no fresh growth capital.
The seller isn't timing the top. IEX sells because it must by a deadline. A genuine "forced seller" dynamic — cuts both ways on pricing.
NOT a red flag on the business. Regulatory dilution, not the parent losing faith. IEX seeded IGX at ₹10 a share and is realising value.
Ownership must disperse. Members capped at 5% each, 49% together, so the register has to broaden.
7. FAIR VALUATION — THE FULL CALCULATION
The number that unlocks everything: IGX has 7.5 crore shares (75,000,000). Derived from IEX holding 35,460,000 shares = 47.28% of the company. That converts every P/E into a real price and market cap.
IGX has no true peer (only gas exchange in India), so it's benchmarked against other exchanges (P/E as of mid-July 2026):
Exchange | P/E | EPS (₹) | RoNW |
|---|---|---|---|
| IEX (parent, power) | 21.5× | 5.54 | 36% |
| MCX (commodities) | 53.3× | 52.2 | 47% |
| BSE (equities) | 64.5× | 60.6 | 37% |
| IGX | ? | 5.68 | 23.5% |
The math — apply each P/E to FY26 EPS of ₹5.68, then ×7.5 crore shares:
Scenario | P/E band | Per share | Market cap |
|---|---|---|---|
| Conservative (~IEX) | 21×–25× | ₹119–₹142 | ₹895–₹1,065 Cr |
| Base (premium to IEX, disc. to MCX/BSE) | 28×–38× | ₹159–₹216 | ₹1,193–₹1,619 Cr |
| Bull (scarcity + runway) | 40×–50× | ₹227–₹284 | ₹1,704–₹2,130 Cr |
How each number is built: e.g. base low = 28 × ₹5.68 = ₹159/share; ₹159 × 7.5 cr shares = ₹1,193 Cr market cap. Same formula throughout.
Now compare to the unlisted market:
Per share | Market cap | Trailing P/E | |
|---|---|---|---|
| Unlisted (₹405) | ₹405 | ~₹3,038 Cr | ~71× |
| Fair base case | ₹159–₹216 | ₹1,193–₹1,619 Cr | 28×–38× |
The takeaway: at ₹405, the unlisted market values IGX at roughly double the fair base range — ~₹3,038 Cr vs a ~₹1,200–1,600 Cr fair zone. Even the bull case (₹2,130 Cr) sits below the unlisted valuation. Pre-IPO buyers are paying a price that only makes sense if you assume years of flawless execution.
The softener: on a forward basis, if FY27 PAT grows ~30% (EPS ≈ ₹7.38), ₹405 is ~55× forward — steep but less extreme. The base band would be ~22×–29× forward. High-growth names get judged on forward multiples, so the gap narrows but doesn't close.
8. THE RISKS — FROM A BUSINESS POINT OF VIEW
This is where the DRHP earns its keep. The real business risks:
The NSE derivatives launch is a double-edged sword. NSE is launching natural-gas futures linked to IGX's GIXI index. Sounds like validation — but it's also a disintermediation risk. Once liquid financial derivatives exist on NSE (financially settled, no physical-delivery hassle, deeper liquidity on a bigger exchange), some players may trade THERE instead of doing physical trades on IGX. The product meant to complement IGX could siphon volume from it — and NSE, a far larger exchange, controls that layer. IGX's moat (physical delivery) is also its constraint.
A new competitor could be authorised any day. IGX is the "only" gas exchange today — but purely by regulatory permission. The DRHP is explicit: if PNGRB authorises a second exchange, IGX may face immediate pressure to cut fees or offer concessions to retain participants. The monopoly is a licence, not a law of nature.
Pricing pressure on its core revenue. IGX operates in a price-sensitive market. Cheaper gas via long-term contracts, direct sourcing, or a new exchange could force fee cuts — and since transaction fees are ~two-thirds of income, even small fee erosion hits hard.
It owns almost nothing it depends on. IGX rents access to the pipelines and 19 delivery points; some key third-party agreements expire as soon as October 31, 2026. Its offices are on leasehold, not owned. Non-renewal or cost hikes on this borrowed infrastructure directly threaten operations.
Brutal customer concentration. Top 10 participants ≈ 66% of revenue. Lose two or three big players and the P&L wobbles.
Exposed to global shocks. ~40% of volume is imported RLNG. When the Strait of Hormuz was disrupted in early 2026, RLNG volumes dipped (then recovered). Crude prices, LNG prices, and geopolitics flow straight into IGX's trading volumes.
Dependence on IEX — which is now selling. IGX leans on IEX's brand, tech, and people via an annual support agreement. And the entity providing that support is the one being forced to sell down. If IEX's involvement fades post-IPO, that crutch weakens.
An auditor qualification exists. The previous auditor included comments in the FY24 audit opinion under CARO 2020. For serious diligence, an audit flag deserves its own look (DRHP page 49).
Treasury income is interest-rate sensitive. That ~28% of income riding on investment gains? It falls if interest rates drop or its debt-fund/commercial-paper investments underperform.
THE WHOLE STORY, IN FIVE LINES
IGX is a toll booth on India's gas trade — runs the marketplace, takes a fee per trade, owns no gas.
High-margin, cash-rich monopoly with a long runway (under 3% of a 24%+ addressable market).
But genuinely small (₹42 cr profit, 1,924 trades/year), a chunk of profit is treasury income, and it even had negative operating cash flow in FY24.
The IPO is a forced Offer for Sale by IEX (25% cap, deadline Dec 2026) — no fresh money reaches IGX.
Fair value works out to ~₹159–₹216/share (₹1,193–₹1,619 Cr); the unlisted market prices it at ₹405 (~₹3,038 Cr, ~71× P/E) — roughly double, pricing in years of perfect execution.
DISCLAIMER: For information and education only — not investment, financial, legal, or tax advice, and not a recommendation to buy, sell, or subscribe to any IPO. Figures are from IGX's DRHP and public sources; the ₹405 unlisted price is an indicative level from UnlistedZone, not an offer to deal or a guarantee of any transaction price. Unlisted shares carry substantial risk, including illiquidity and no guarantee any IPO occurs. Past performance doesn't indicate future results.
