With the fifth and final day of Cannes Lions officially in the books, the winners of some of the festival’s most prestigious categories have now been named. Those who have eagerly awaited the Grand Prix reveals for Glass: The Lion for Change, Sustainable Development Goals, Film, Dan Wieden Titanium Lions, and the Grand Prix for Good can finally have their curiosity sated.
Across the final five categories, there’s winning work from Australia, the UK, Brazil, Mexico, and even Kenya – a first for the country. From two hilarious films for Claude, to an initiative which literally exposed voting fraud in Venezuela, the work is diverse, powerful, and worth watching.

Dan Wieden Titanium Lions
Due to local conditions, it’s estimated that by 2035, 10% of Australian homes could be uninsurable. This obviously isn’t an ideal prospect for Suncorp Insurance, which is why the brand partnered with Leo Australia to change its focus from recovery, to resilience. In 2021, they created a house capable of withstanding almost all extreme conditions. After that, they proved it was scalable, applying the learnings to a whole street. And now, after years of research, they’ve created a digital platform, based on 12 proprietary data sets.
Available to all homeowners across the country – even those insured by competitors – this website enables people to type in their address, and hear from their own home precisely what it needs to be more resilient. Leading to 323,000 visitors since launch, 79% of users have since planned to make their homes more resilient.
Explaining the selection, jury president Chaka Sobani, global chief creative officer, TBWA\Worldwide, said, “We were looking for brands that are making a genuine commitment to a platform with a business strategy built around resilience, rather than simply recovery.
“This has been years in the making. And then there was the generosity of open-sourcing it. This wasn't created just for a core group of customers, but for the whole country, because the issue affects everyone. The solutions it offers are both large and small, meaning they're not limited by someone's income or circumstances.
“More importantly, when resilience truly sits at the heart of your business, it changes how you operate. Suncorp has committed to lobbying Parliament, working with building contractors, and helping ensure that new homes in Australia are built differently and more resiliently. It isn't just an idea for this year. It's an ongoing platform with the potential to create seismic change for the future of Australian homes.”

Film Lions
Created by Mother and directed by Biscuit Filmworks’ Jeff Low, both films for Claude have taken home a Grand Prix for their dark, comedic, sense of humour. Poking fun at the concept and existence of ad-supported chatbots (weeks after OpenAI announced plans to introduce advertising to ChatGPT), here, everyday questions about fitness and family quickly spin into irrelevant ads, all to emphasise the brand’s stance that advertising doesn’t mix with its platform.
Reflecting on this double selection, jury president Pelle Sjoenell, worldwide chief creative officer, NLS Corp, shared, “It's an ad about where ads shouldn't exist. It's AI making fun of AI – a challenger taking on the market leader by using the leader's own announcement against itself. It's like corporate Aikido, executed with wit, nerve, and craft in every frame. The risk was profound, the execution was immaculate, and it reshaped perceptions in one of the world's most consequential technology categories. The humour is just incredible. The nuance, the detail; you can watch it many times and still notice new things each time. And on such an important topic, it's really changing the game in the biggest way.”

Glass: The Lion for Change
Winning this heavyweight category – and its second Grand Prix in two years – is Artplan’s initiative for Idomed and Instituto Yduqs. Firm believers that education is the cure to the disease that is racism, the group took on Brazil’s systemic issues with healthcare, such as the fact that it’s six times more likely for Black patients to suffer medical errors in the country (all while 55% of the population falls under this demographic).
The result was the launch of a beautifully-made book, which not only depicts Black bodies in artistic, striking fashion, but explains the various ‘diseases’ that facilitate racist behaviour within the practice. An endeavour which was subsequently adopted by 17 different institutions, this creation would eventually make its way into the hands of the country’s minister for health.
Speaking on the selection, jury president Monique Nelson, executive chair, UWG, said, “We know if we can solve problems – [like curing] cancer [and] diabetes – then we can cure racism. But we do need to treat it systemically. We need to treat in a way that is process-driven, and make sure that we are educating at every level.
“[‘Nigrum Corpus’] was groundbreaking, and this [is] now documented. We know that if you don't put it all together and you don't put it on the curriculum, it will not change. This is remarkable. We are very proud of it. And we are just honoured that this is our Grand Prix.”
Sustainable Development Goals Lions
Statistically, Kenya has the highest per capita milk consumption in all of Sub-Saharan Africa. Smallholder farmers make up 80% of dairy producers, but one in four samples test positive for antibiotics, leading to critical loss of income for farmers.
Cognisant that if farmers were paid more, this problem could be avoided – but that market prices can’t be raised – The Partnership Agency and Too Good were inspired by the sick leave model, and decided to register cows as proper economic workers, rather than livestock. By doing this, the farmers were compensated for the cows’ ‘paid sick leave’, leading to $27,000 returned to farmers for milk that was withheld (within eight months), and 100% farmer income protected with this model.
Commenting on Kenya’s first-ever Grand Prix win, jury president Kazoo Sato, chief creative officer and CEO, Earth Centric Design, noted, “For decades, we've accepted that when people get sick, they deserve time to recover. This work asked a simple but powerful question: if recovery matters for people, why not for cows? It was a very small shift in perspective that led to a major shift in the system. Instead of forcing a trade-off between animal welfare and economic growth, it aligned the interests of both.
“So it removes all the friction. I think it shows that a new set of rules can emerge from creative thinking. Not only for people, but also for other species and the living systems that support all of us. To me, that's what truly creative work looks like. It's not just about solving today's issues, but about using creativity to redesign systems in ways that create lasting change. And that's the kind of impact that endures.”
Grand Prix for Good
In 2024, Venezuela was still under dictatorship conditions. The opposition candidate had been barred, and the party had no funding, paystubs, lobbyists, or any way to prove their electoral viability. Fortunately, Commando Con Venezuela and Rainbow Lobster found a vulnerability in the form of the QR codes generated by voting ballots, and recognised the chance to turn this citizen verification system into international pressure and media validation.
Secretly training 600,000 volunteers to scan each QR and transmit results, the involved parties were able to prove a different outcome when the dictator tried to keep power. Publishing 85% of the ballots two days later, a global public affairs playbook then delivered this evidence to credible validators who moved the truth to different channels. Leading to a Nobel Peace Prize honouring the people who defended the truth, and international recognition of the situation, this massive undertaking made a genuine difference.
Speaking on the initiative, jury president Chaka Sobani commented, “We talk a lot about bravery at Cannes, and there are certain ideas that truly embody that value. At the heart of this work was an extraordinary example of how creativity can unlock hope and create solutions where more traditional diplomatic approaches have been unable to. The scale of what was achieved is astonishing. The infrastructure that had to be built, the trust that had to be earned, the secrecy that had to be maintained, it was all remarkable. There were two phases. The first involved recruiting 600,000 volunteers and installing the network needed so that QR codes could be transmitted back and securely logged. And when I say things were hidden, they were hidden in places like watermelons. It was on an entirely different level.
“Then came phase two: during the election itself, those 600,000 volunteers sent back the data needed to verify the true results. The verification by the Carter Center and The Washington Post reinforced its credibility, and the fact that 49 countries called for transparency at the United Nations is an extraordinary achievement.”
