How to Spot Fake Investment Offers During a Major IPO

Last checked: 14 October 2026. This guide draws on the SEC’s warnings during the Dangote Refinery IPO and on earlier SEC notices. It is general safety guidance, not investment advice.

Whenever a big, popular investment opportunity appears, scammers appear with it. The Dangote Refinery IPO, which opened on 14 September 2026 and now closes on 27 October, is described as Africa’s largest share sale, and it has all the ingredients fraudsters like: public excitement, a low minimum of ₦5,250 and people who have never bought shares before. The SEC warned about this on the day the offer opened. This guide explains the tricks to expect, how to check whether an offer is real and what to do if you have already paid someone.

What the SEC said

On 14 September 2026 the SEC warned investors against fraudulent platforms and unauthorised agents trying to collect applications or money for the refinery IPO. It told the public to apply and pay only through approved receiving agents, registered capital market operators and officially designated channels. It said strong public interest could encourage fraudsters to use fake websites, social media accounts and unsolicited messages. It advised people to get information only from the SEC, the issuer and other approved channels, to verify that a platform is authorised before sharing personal or financial details, and to ignore unsolicited calls, WhatsApp messages, social media advertisements and emails that offer or guarantee allotments or preferential treatment. Reports named NGX Invest, designated commercial banks and authorised investment platforms as subscription routes.

Common tricks to expect

• “Guaranteed allotment.” Someone claims that for a fee they can make sure you get shares. The SEC specifically warns against offers of guaranteed or preferential allocation.
• The “agent” who takes cash. A person says they collect applications, perhaps on a street, at an office or in a church or WhatsApp group, and asks you to transfer money to a personal account.
• Fake websites and apps. A page that copies the look of a bank, a broker or the offer’s own site, perhaps with a similar web address.
• Fake social media accounts. Accounts using the Dangote name, logo or photos to promise early access, bonuses or “shares for students”.
• Private resale schemes. Offers to sell you shares “before listing” at a markup, or to sell you a “slot”.
• Foreign-investor traps. Offers aimed at investors outside Nigeria. Kenya’s Capital Markets Authority published a notice saying the offer had not been submitted for approval there, which shows that an offer’s legality can depend on where you live.
• Hot tip groups after listing. Signals and “sure profit” calls that appear once shares start trading.

A seven-point check before you pay

1. Start from the official source. Use the SEC’s channels, the issuer’s announcements and the prospectus to identify approved channels.
2. Verify the platform. Confirm that the bank, broker or app is a registered capital market operator and that it is approved for this offer. Our guide on checking SEC registration shows how.
3. Check the address. Type the website yourself. Do not click links in messages, and watch for small spelling changes.
4. Pay only into the official account shown inside the verified platform, never into a personal account.
5. Test the story. A genuine application does not need an “activation fee”, a “processing fee” or a promise of a guaranteed profit.
6. Protect your details. Do not share your BVN, OTP, card PIN or login with an “agent”.
7. Take your time. The deadline was extended to 27 October so you do not need to rush.

Free shares and special offers

Some real programmes exist. Reports say the Aliko Dangote Foundation is offering free shares to verified students who subscribe to a minimum number through a dedicated platform. That makes this area attractive to impersonators. If you see such an offer, find it from the foundation’s official channels, not from a forwarded message, and never pay to “unlock” it.

If you have already paid a fake agent

1. Stop sending any further money, including any “release” or “tax” fee.
2. Screenshot the chats, account numbers, receipts and website.
3. Call your bank immediately and ask about a dispute or trace.
4. Report to the SEC and to the police or the EFCC.
5. Warn friends and family who may have received the same message.
6. Beware of “recovery agents” who ask for a fee to retrieve lost money, since they target victims.

After the IPO

When shares list, fake tips and impersonators tend to continue. Buy and sell only through your registered broker, and be cautious about anyone selling shares privately or promising returns.

What we could not confirm

• How many people have actually been defrauded. I found no public figure.
• Whether the SEC has named specific fake platforms. The warnings I read were general.
• The full list of approved receiving agents. Check the prospectus and the SEC’s channels.

Frequently asked questions

Key takeaways

Fraudsters follow big offers. During the Dangote Refinery IPO, use only approved channels, verify platforms and links, never pay a personal account or an activation fee and ignore anyone who guarantees shares. If you have paid a fake agent, act quickly: tell your bank, keep evidence and report to the SEC and the police.
