Adrian Portelli spent $15 million on The Block houses. Here's what he plans to do with them.

Another season of The Block has come and gone, with multiple teams reaching millionaire status in Sunday night's nail-biting finale.

And all of our favourite contestants have one man to thank: Adrian Portelli. Yep, the 'billionaire bidder' bought the lot.

After bursting onto The Block scene in 2022, Portelli returned this season to drop millions of dollars on auction day on Phillip Island.

He spent $15.03 million, to be exact.

And now he's planning to give all five homes away in a major move for his business, LMCT+, an online marketplace and rewards platform.

To announce the news, Portelli shared a photo of himself on Phillip Island on Instagram.

"Under New Management!" he captioned the post. "And as mayor of Portelli town, I would like to announce a world first. LET'S GIVE AWAY A FKN RESORT!!!"

"1 Giveaway - 1 Prize - Winner takes the whole resort OR take $8,000,000 Instant Tax-Free Cash! Let the games begin."

It's a move that's been applauded by The Block winner, Maddy.

"You've changed our lives forever and now you're going to change someone else's too," she commented on his post.

Portelli's historic run on auction day was truly impressive.

First, he bought Courtney and Grant's House 2 — for a cool and casual $3.3 million, with the couple taking home $1.35 million in profit. Talk about starting off strong.

Then, he bought Kylie and Brad's House 4. While he didn't drop quite as much on their place, he did purchase the property for a whopping $2.6 million. The couple took home $650,000.

Using a dummy bidder, Portelli also bought Kristian and Mimi's place. Surprise! The home sold for $2.93 million, leaving them with a profit of $1.03 million above their $1.9 million reserve. WOW.

"All the contestants were playing the game, so I thought I'd play the game back. I didn't want anyone to know what we were doing," he said of the 'gotcha' moment.

Up next, Portelli bought Haydn and Ricky's House 3.

Their home sold for $2.75 million, meaning they made $750,000 above their reserve.

And finally, he made the ultimate bid on Maddy and Charlotte's House 1: dropping $3.5 million in a move that would see them take home $1.55 million in profit (plus $100,000 in winnings).

"We are just so grateful, and it's a very surreal feeling," said Maddy. "You can't anticipate how something like The Block will end, but it is the perfect ending for us. I think there is such a special relationship with sisters, and I'm so proud of both of us and how hard we worked."

In the hours since, Portelli has admitted he 'rigged' the auction results in favour of the girls — and even encouraged them to choose fifth in auction order.

"We hand selected the auction order make sure the girls went last. So we can get them to win," Portelli said on Nova this morning.

Why?

"It's the girls. They cared. They came in late. They were the underdogs. They were picked on. They were bullied," he says, adding his partner is a big fan of The Block and had backed the girls.

Portelli also admitted that the girls knew his plan all along — but none of the other teams had been warned.

"It was just the girls. How good is that? The girls that are the most sweetest and innocent, were playing the game the best," he said.

Following his stunning sweep, Portelli announced this would be his final appearance on The Block. Who is this mystery man known as 'Mr. Lambo'? Here's everything we know.

Who is Adrian Portelli?

Coming to public attention in 2022 on The Block, Adrian made a name for himself as a wealthy and strategic entrepreneur.

At only 34 year's old, Adrian is one of the youngest billionaires in Australia.

He owns several businesses and also engages in a range of philanthropic endeavours, such as his Little Legends Foundation. The organisation seeks to support and aid underprivileged children in the community.

How does Adrian Portelli make money?

For Adrian, the hustle to become wealthy and successful started when he was young.

"I'm always humble because where I got to wasn't easy," he told the Australian Financial Review in 2023.

As a young man, Adrian started off working at his father's truck repair shop after dropping out of university. Shortly after, he moved to LA, where he founded multiple fairly successful apps that he later sold.

Adrian founded LMCT+ in 2018. It's an auto-enthusiast rewards club that offers subscription members access to prizes including luxury homes, cars, and boats, via monthly draws.

Subscribers also get exclusive offers from more than 1,000 partners including Beaurepaires, Patriot Campers and Prestige Autoworks.

"Our platform not only facilitates access to exclusive deals from more than 1,000 partners but also empowers shoppers to make smart, cost-effective purchases all in one place," Portelli says of his business.

"Some 100,000 members pay between $20 and $100 a month to access discounts from its partners, and entries to giveaways," the AFR reported in 2023.

"The paper value of LMCT+, which Portelli started in 2018, is the main source of his wealth. Add in large collections of sports cars and properties, and his estimated valuation is $1 billion, which puts him in seventh spot on the 2023 AFR Young Rich List."

Then in 2024, Adrian was listed number 115 on The List—Australia's Richest 250, with the publication placing his net worth at $1.3 billion.

Adrian Portelli's first appearance on The Block.

On first glance, property investor and entrepreneur Adrian Portelli seemed flashy. He pulled up at Omar and Oz's auction in 2022 in a yellow Lamborghini and earned himself the nickname 'Mr. Lambo'.

His impressive appearance the following year on Auction Day on The Block 2023 turned even more heads, when he purchased not one, not two, but three houses in a single day.

But a closer look at 'Mr. Lambo' proves there is a lot more to him and his achievements.

How many homes has Adrian Portelli bought on The Block? 

In 2022, Adrian bought Sharon and Ankur's house after Auction, for a casual $4.25 million. He had initially wanted to buy Oz and Omar's home, but was outbid by Danny Wallis.

He was accused of being a 'dummy bidder' and intentionally driving up the prize of Oz and Omar's house, but he says his intentions were always honourable.

The following year in 2023, Adrian bought 3 houses on on Charming Street. He spent $12.4 million.

"After the slack I copped last year, I had to prove I'm not a dummy bidder," he told Nine. "I came out hard and strong."

In the 2024 season, he was certainly in the mood to purchase big.

"The houses will all sell for the one price and the well-established Adrian Portelli wants them all," an insider had previously told Yahoo Lifestyle.

"Adrian has been very vocal during discussions with the producers and has also told his close friends he will be buying the entire resort for his LMCT+ website for up to $15 million. It will be the noisiest sale in Block history and that's perfect for his business model."

In the end, it turns out he did actually buy the lot for just over $15 million.
