Looking for an easy way to get started with investing? With Trading 212, you can earn a free fractional share worth up to €100 just by opening an account and making a small deposit. Whether you use my referral link (Sponsored Link) or manually enter the promo code KAI, the reward is the same: a free fractional share to kick off your portfolio. Terms apply.
This is the platform I personally use and recommend for new and intermediate investors looking for a simple, commission-free way to invest in stocks and ETFs. I made a detailed review video about it which you can check out to learn more.
How to Get Your Free Fractional Share
You can unlock your free fractional share in two ways, whichever works best for you.
Option 1: Use the Referral Link
Option 2: Use the Promo Code in the App
Already signed up without a referral link? No problem:
- Open the Trading 212 app
- Go to Settings then Use Promo Code
- Enter KAI
- Deposit at least €1
- Your free fractional share will be credited automatically
Trading 212 Minimum Deposit for the Free Fractional Share
The minimum deposit to qualify for the free fractional share is just €1. There is no requirement to invest that €1, you can leave it as cash if you prefer. The deposit needs to be made within 10 calendar days of opening your account using the promo link, or within 10 days of entering the promo code KAI in the app.
You can fund your account using bank transfer, debit card, Apple Pay, or Google Pay. Once the deposit clears, the free fractional share is typically placed in your account within three business days.
Free Fractional Share Value Range and Probability
The free fractional share is selected at random from a pool of well-known companies, with examples including Tesla, Apple, Microsoft, Nvidia, and Coca-Cola. The monetary value can range from €8 up to €100, depending on the share Trading 212 allocates.
Higher-value shares are weighted with lower probability, so most users receive a share at the lower end of the range. Trading 212 publishes the official value probability, which breaks down as follows:
Source: Trading 212 Promo Code Terms. Shares are randomly selected in terms of value and company.
When Can You Withdraw the Free Fractional Share?
The free fractional share comes with a 30-day lock-up. This means that after Trading 212 places the share in your account, you cannot withdraw the monetary value associated with it for 30 calendar days. You can still buy and sell other investments in your account during that period, the lock-up applies only to the reward itself.
After the 30-day lock-up ends, you are free to either keep the share long-term, sell it and reinvest the cash in other stocks or ETFs, or withdraw the proceeds back to your bank account.
You also have the option to refuse the reward share within 24 hours of it being placed in your account. If you decline it, you will not be eligible to receive a different reward share, so most users keep whatever Trading 212 allocates.
Who Is Eligible for the Trading 212 Promo Code?
To claim the free fractional share with promo code KAI, you must be a new Trading 212 customer and reside in a country where Trading 212 operates (Australia is excluded). The promo applies to new Invest Accounts and UK Stocks ISA Accounts. CFD accounts and Cash ISAs are not eligible.
You also cannot have held a Trading 212 account previously, and you cannot use more than one promo code per account. Employees of Trading 212 and close relatives are excluded.
If you signed up to Trading 212 previously but never made a deposit, you may still be eligible. The promo is triggered by the first qualifying deposit on a new account that meets the eligibility criteria above.

I also made a full video walkthrough on how to invest using Trading 212, covering everything from setting up your account to building your first portfolio:
Can I Refer Friends After Signing Up?
Absolutely. Once your account is active, you will get your own referral link to invite others. Both you and the person you refer will receive a free fractional share, so it is a straightforward way to build your portfolio while helping friends get started.
Is This Offer Still Active?
Yes, in 2026 the promo code KAI and the referral link are both still active. These types of promotions can change at any time though, so if you are thinking about signing up, it is smart to take advantage sooner rather than later.
Frequently Asked Questions
The minimum deposit is €1. You need to make this deposit within 10 calendar days of opening your account using the promo link, or within 10 days of entering the promo code KAI. You do not have to invest the €1, you can leave it as cash if you prefer.
The free fractional share has a monetary value between €8 and €100. Higher-value shares are weighted with lower probability: 80% of users receive a share worth €8 to €25, 15% receive €25 to €50, 3% receive €50 to €75, and 2% receive €75 to €100.
There is a 30-day lock-up on the reward share. You cannot withdraw the monetary value associated with it for 30 calendar days from the date Trading 212 places the share in your account. The lock-up only applies to the reward itself, not to other money or investments in your account.
The Trading 212 promo is available in every country where Trading 212 onboards new clients, which covers most of Europe and the UK. Australia is excluded. The promo only applies to new Invest Accounts and UK Stocks ISA Accounts, not CFD or Cash ISA accounts.
No, you just need to deposit €1 to activate the promo. Whether you invest it or leave it as cash is entirely up to you.
Trading 212 typically places the free fractional share in your account within three business days of meeting the eligibility criteria. Weekends or public holidays may add a short delay.
Make sure you are entering the code exactly as KAI (all caps). If you already used a different referral or promo code when signing up, you may not be eligible for a second one. In that case, try signing up fresh using the referral link instead.
Trading 212 is authorised and regulated by the FCA (UK), CySEC (Cyprus), and BaFin (Germany). Client funds are held in segregated accounts, and eligible client investments are covered up to €20,000 under the Investor Compensation Fund (or up to £85,000 under the FSCS for UK clients), subject to scheme eligibility conditions. As with any investment, your capital is at risk and you may get back less than invested.
