Stock Market Abu Dhabi: How ADX Actually Works in 2025

If you're thinking about putting money into the stock market Abu Dhabi side of the UAE — or you're a founder eyeing a listing — the rules look simple from a distance and get complicated fast. The exchange has changed a lot since 2021. Most retail guides online are out of date.

Here's what you actually need to know before you open an Investor Number or sign a subscription form.

Quick answer

The stock market Abu Dhabi operates through the Abu Dhabi Securities Exchange (ADX), regulated by the UAE Securities and Commodities Authority (SCA). To trade, you need an Investor Number (NIN) from ADX, a brokerage account with an SCA-licensed broker, and an Emirates ID or passport. NIN issuance is free as of 2024. Trading hours run Monday to Friday, 10:00 to 15:00 GST. Settlement is T+2. Foreign ownership is allowed in most listed companies, but some sectors still cap non-GCC ownership. Capital gains tax? Zero, for individuals.

What ADX actually is — and isn't

The Abu Dhabi Securities Exchange was set up under Local Law No. 3 of 2000, then absorbed into the broader federal regime under SCA oversight. It's one of two main UAE exchanges. The other is the Dubai Financial Market (DFM). Don't confuse either with Nasdaq Dubai, which is a separate USD-denominated exchange sitting inside the DIFC (Dubai International Financial Centre) free zone.

ADX trades equities, sukuk, ETFs, REITs, and — since 2023 — single-stock futures through ADX Derivatives. Market cap crossed AED 2.9 trillion in 2024, making it the second-largest exchange in the MENA region after Saudi Tadawul. [1]

Honestly, most retail investors I meet think ADX and DFM are interchangeable. They aren't. Different listed companies, different settlement infrastructure, different fee schedules. You need a separate NIN for each.

The big names you'll see: International Holding Company (IHC), ADNOC Gas, ADNOC Drilling, First Abu Dhabi Bank (FAB), Aldar, Etisalat (e&), Multiply Group. IHC alone makes up a chunk of the index that should make any portfolio manager nervous about concentration risk.

Opening an account — what the process really looks like

Two things you need before you can buy a single share on the stock market Abu Dhabi: an Investor Number (NIN) from ADX, and a brokerage account with an SCA-licensed firm.

The NIN application went fully digital in 2022. You apply through the ADX website or the Sahmi app. Documents required: Emirates ID for residents, passport plus proof of address for non-residents, and bank account details for dividend payments. Processing usually takes one to two business days. Sometimes same-day.

The brokerage side is where people slow down. SCA licenses around 30 brokers, but only a handful actually serve retail clients well. EFG Hermes, FAB Securities, ADCB Securities, Al Ramz, International Securities — those are the ones most active. Minimum account opening deposits range from AED 1,000 to AED 10,000 depending on broker.

Non-residents can absolutely trade ADX. You don't need a UAE residency visa. You do need to physically come to the UAE once to complete KYC with most brokers, though a few now offer fully remote onboarding for clients from approved jurisdictions.

Costs to expect (2025):
- NIN issuance: free
- Brokerage commission: 0.275% of trade value, with a minimum of AED 10.50 per trade
- ADX trading fee: 0.025%
- Clearing fee: 0.025%
- No capital gains tax, no dividend tax for individuals

Trading mechanics and the bits that catch people out

Trading hours are 10:00 to 15:00 GST, Monday through Friday. Pre-open auction starts at 09:30. The closing auction runs 14:55 to 15:00, and that's where a lot of the day's price discovery actually happens — especially for less liquid names.

Settlement is T+2. Sell a share on Monday, cash hits your account Wednesday. You can't pull funds before settlement.

Short selling exists, but it's restricted. You need a margin account, and only certain securities are on the eligible list published quarterly by ADX. Don't assume you can short anything that moves.

Foreign ownership limits are the single most-missed detail in the stock market Abu Dhabi. Each listed company sets its own foreign ownership cap in its articles of association. Some are 100% open. Some cap non-GCC ownership at 40% or 49%. When the cap is hit, foreigners physically cannot buy more shares on-exchange, even if you have the money and the order is in. Check the FOL (Foreign Ownership Limit) on the ADX company page before you build a position you can't actually fill.

Watch out: Dividend payments require accurate IBAN details registered against your NIN. If your bank account closes or changes and you don't update ADX, dividends sit in suspense — sometimes for years. Update through the Sahmi app or your broker.

Listing on ADX — for founders, not just investors

If you're on the issuer side, ADX has two main listing venues: the Main Market and the Second Market (a growth board launched in 2021 for smaller and family-owned businesses).

Main Market requirements include a minimum paid-up capital of AED 10 million, at least three years of audited financials, a minimum free float of 25%, and a track record of profitability. The full rulebook is in the SCA Chairman Decision No. 11/R.M of 2016 on the Regulations of Issuing and Offering Shares of Public Joint Stock Companies, as amended. [2]

The Second Market is friendlier. Lower capital threshold (AED 5 million), shorter track record requirements, and a smaller minimum free float. Several family businesses have used it as a stepping stone to a full Main Market listing.

Realistic IPO timeline: 9 to 14 months from kicking off the process to bell-ringing. Frankly, the bottleneck is almost always the financial restatements and the regulatory back-and-forth with SCA, not market timing. Lead managers will tell you they can do it in six months. They can't, not if your accounts need cleaning up.

The ADNOC IPO spinoffs from 2022-2024 reset everyone's expectations on what an Abu Dhabi listing can raise. ADNOC Gas alone pulled USD 2.5 billion. That's not a normal data point. Don't price your AED 200 million family business off it.

Disputes, regulation, and where things go when they go wrong

SCA is the federal regulator. ADX is the exchange operator. Two different bodies, two different roles. If you have a complaint about a broker's conduct — unauthorized trades, mis-selling, fees not disclosed — you complain to SCA first under the SCA Investor Protection rules. If your dispute is about clearing, settlement, or corporate actions, you go to ADX.

Civil claims for damages (recovery of losses from broker misconduct, for example) go to the Abu Dhabi civil courts unless the brokerage agreement says otherwise. Some brokers contract into ADGM Courts (Abu Dhabi Global Market) instead — read your client agreement before you sign. The forum-selection clause matters more than people realise when they're rushing to open an account.

Insider trading is a criminal offence under Federal Decree-Law No. 32 of 2024 on Commercial Companies and the SCA market conduct rules, with penalties including imprisonment and fines up to AED 10 million. [3] Market manipulation prosecutions have picked up since 2022 — SCA is more active than it used to be.

What I'd actually tell a friend

Three things, before you put real money into the stock market Abu Dhabi.

First, the concentration risk in the index is real. ADX General Index performance is heavily driven by a small number of names. If you're buying the index through an ETF, you're not as diversified as the word "index" suggests.

Second, liquidity outside the top 15-20 names is thin. Posting a market order for AED 500,000 of a mid-cap name can move the price against you 2-3%. Use limit orders. Always.

Third, the tax-free environment is genuine for individuals, but if you're a corporate investor based in the UAE, the 9% federal corporate tax that came in for financial years starting on or after 1 June 2023 may apply to your trading gains depending on your structure. Get advice before you assume "tax-free UAE" applies to your situation.
