Two premium bond holders have each won £1m in August's National Savings & Investments (NS&I) prize draw.
The jackpot winners are from Kent, and Hampshire and Isle of Wight. Plus, 83 other winners were picked for the next-best prize of £100,000.
If you didn't become a millionaire this month, you may still have struck it lucky with a smaller prize. You can check whether your numbers came up by using our table.
The first winning bond (664BF890888) was bought by a lucky winner living in Kent and is part of a total holding of £21,000. The winning bond was bought in February 2026.
The second winner, from Hampshire and Isle of Wight, bought their bond (491KF169443) in March 2022. They have a total holding of £49,850.

There were 6,224,837 premium bond prizes paid out in the August 2026 draw, worth a total of £433,663,575. There were 83 prizes worth £100,000, but plenty of smaller cash rewards were also up for grabs – 6.204,428 were worth £500 or less.
The odds of winning any prize are currently 22,000:1. All £1 bonds that enter the prize draw each month have an equal chance of being picked.
To understand what this really means for premium bond holders, it's important to explain what's meant by 'odds'.
In the case of premium bonds, 22,000:1 indicates that for every 22,000 attempts, one is expected to succeed – assuming each attempt is independent of the other. In short, your chances are pretty slim and, in an average month, a typical bondholder is likely to win nothing at all.

Join Which? MoneySome people believe that having newer bonds makes you luckier. Although it’s true that recent bonds win more often, that’s simply because there are more of them in circulation.
Sales surged after the top prize rose to £1m in 1994, and low interest rates have encouraged more people to put their money into premium bonds instead of other savings products. Two increases to the prize fund rate in 2022 may also have prompted more purchases.
Older bond numbers are more likely to have already been picked as jackpot winners, as they’ve been entered into more draws over the years.
Ultimately, there’s only one guaranteed way to boost your chances: buy more bonds. The more you invest, the greater your odds of taking home a prize.
Unlike premium bonds, savings and Isa accounts offer guaranteed interest on your deposits.
Many savings products allow you to open with less than £1,000, so they might be a better option for people who don't have a huge lump sum to invest.

Compare and chooseNS&I does offer a range of savings and Isa accounts. However, its top rates tend to be lower than those offered by competitors.
One of the main advantages of NS&I, however, is that funds are backed by HM Treasury, so your money has 100% security.
Other banks and building societies are covered by the Financial Services Compensation Scheme (FSCS), up to £120,000 per person, per institution (meaning some brands share protection).
With NS&I you’re fully protected up to the maximum deposit limit on the account. For the Direct Saver instant-access account, that’s up to £2m.
In March 2026, it was revealed that NS&I is expected to pay back hundreds of millions of pounds to the families of customers who have died.
This follows an error in processing bereavement claims that failed to identify all NS&I products linked to some customers. Around 37,500 bereavement cases are thought to be affected, with missing payments estimated to total up to £476m.
This meant that some savings and premium bond prizes were not paid out or were delayed, leaving families waiting for money owed to estates.
NS&I has now published its delivery plan. It is currently in the process of contacting affected estates about reimbursement and compensation. Payments will begin shortly after the letters are sent and received.
