Adyen’s 2018 IPO was priced at €240 per share, valuing the payments company at about €7.1 billion using then-outstanding shares, or approximately €7.3 billion on a fully diluted basis. The widely reported “up to $8.3 billion” figure was a contemporaneous dollar conversion of the high end of the earlier indicative range—not a current valuation. The offering sold existing shareholder shares, rather than raising that amount for Adyen.
What did “up to $8.3 billion” mean?
When Adyen published its indicative IPO terms on 5 June 2018, it set a price range of €220 to €240 per share. At that stage, the range implied a market capitalization of €6.5 billion to €7.1 billion based on then-current outstanding shares. The company separately put the post-offering equity value at approximately €6.7 billion to €7.3 billion on a fully diluted basis. Reuters’ contemporaneous dollar conversion of the indicative range was $7.3 billion to $8.3 billion; the headline’s upper figure refers to that conversion, not to a dollar valuation published by Adyen. Adyen’s 5 June 2018 announcement gives the euro terms.
Those figures differ because they use different share counts. Market capitalization based on current outstanding shares excludes certain potential shares; a fully diluted calculation accounts for them. They also describe the indicative range, not the final price. The figures are historical and should not be read as Adyen’s value today.
How the IPO valuation changed from the range to final pricing
| Stage | Share price | Value using then-current shares | Fully diluted value |
|---|---|---|---|
| Indicative terms, 5 June 2018 | €220–€240 | €6.5–€7.1 billion | Approximately €6.7–€7.3 billion |
| Final offer, 11 June 2018 | €240 | €7.1 billion | Approximately €7.3 billion |
Adyen announced the final €240 offer price on 11 June. The final-price figures are from its pricing announcement. The €7.1 billion and approximately €7.3 billion values are compatible, not competing estimates: one uses then-outstanding shares and the other a fully diluted share count.

Did Adyen raise new money in the IPO?
No. The offer consisted of existing shares sold by certain shareholders. Before any over-allotment, the initial placement comprised 3,537,754 shares—about 12.0% of issued and outstanding capital—and had a total offering size of €849 million. If the over-allotment option was exercised in full, the offering would total approximately €947 million, or 13.4% of capital. These are offering proceeds associated with selling shareholders, not new capital raised by Adyen itself. The company described the sale mechanics in its final IPO pricing release.
When did Adyen go public?
Adyen began trading on Euronext Amsterdam on 13 June 2018 under the ticker ADYEN. Euronext’s debut notice confirms the first trading date and reports an offering size of €849 million and a market capitalization of about €7.1 billion at the offer price.

What Adyen did at the time
Adyen described itself in 2018 as an integrated payments platform for merchants operating across channels and geographies. It reported processing €108 billion in payment volume in 2017, up 63% from €66 billion in 2016. Processed volume is the value of transactions authorized through the platform; it is not Adyen’s revenue. In its 5 June announcement, the company named Facebook, Uber, Netflix, Spotify and L’Oréal among its customers. Those business descriptions and figures are company-reported statements from 2018, not current operating metrics.

The €240 offer price and implied valuations describe the terms at which shares were offered in June 2018. They do not establish whether Adyen shares are attractive today, and the historical dollar conversion should not be treated as a current share price or present-day market capitalization. Adyen’s pricing announcement said investment decisions should be based solely on the prospectus, which set out risks relating to the company, its shares and the offering.
