So far, the 2025 NRL finals series has proven to be one for the ages.

Whether it be the minor premiers being knocked out in straight sets, golden point thrillers or the travelling Cronulla Sharks fans sending the Canberra Raiders home with their own rendition of the Viking clap.

Each week has delivered something unforgettable.

However, as the dust settles, only four teams remain and three games are left until one of them raises the Provan-Summons Trophy and etches themselves into NRL history.

Each club has its own story and each club has a chance, but how good a chance is the real question.

So, let's look at the probability of them winning the 2025 NRL Grand Final.

3. Brisbane Broncos

The Brisbane Broncos' season has been nothing short of tumultuous, with the club seemingly under the microscope every step of the way.

Their form has been rocky, stringing together winning runs, only to follow them with losing streaks.

What's important, though, is that they've hit form exactly when needed.

The Broncos have won five games in a row, with their two most recent wins being over the Melbourne Storm and Canberra Raiders, formidable opponents, to say the least.

Reece Walsh, despite his off-field antics, is in career-best form, with six tries and eight try assists in his last five games.

The return of both Adam Reynolds and Ezra Mam is also a massive boost for Michael Maguire's side.

At first, the thought of the Broncos winning seems far-fetched, but on a closer look, it isn't unrealistic.

They've proven they can beat the best teams in the competition, so what's stopping them?

Penrith.

The Broncos have only beaten the Panthers once in their last ten meetings, dating all the way back to 2021, which will no doubt be in the back of their minds heading into Sunday's preliminary final.

But if they can take down the reigning premiers, anything is possible.
