Disney+ may soon have a Harry Potter problem.
Percy Jackson and the Olympians is due to return for Season 3 toward the end of 2026, continuing Disney’s adaptation of Rick Riordan’s bestselling fantasy series.
The new episodes will arrive as HBO prepares to launch its Harry Potter reboot over the holiday period, putting two major young-adult fantasy franchises into the same release window.
Disney has not canceled Percy Jackson, but fans fear the arrival of Harry Potter could overshadow Season 3 and damage the show’s chances of receiving a fourth season.
The timing places two major young-adult book adaptations in the same holiday window, with both competing for families, fantasy viewers and readers who grew up with the original novels.
Harry Potter Could Dominate the Holiday Season
HBO’s Harry Potter reboot has generated intense attention since it was announced.
The series will revisit the story previously adapted into eight blockbuster films starring Daniel Radcliffe, Emma Watson and Rupert Grint. Its new television format is expected to provide more time for characters, locations and plotlines excluded from the movies.
That approach could prove particularly threatening to Percy Jackson, which has faced criticism from some readers over its pacing, shortened action scenes and changes to key moments from Riordan’s books.
Although Riordan is closely involved with the Disney+ production, the series has not escaped comparisons with the source material. Viewers have repeatedly debated whether the adaptation captures the scale, humor and excitement that made the novels successful.
One fan predicted that the competition would become even more difficult once HBO begins promoting Harry Potter.
“Once Harry Potter comes out the PJO show could become irrelevant no matter when it’s released. If it gets everything right that PJO has got wrong then it’ll be a massive hit and will once again dwarf everything in sight.”
The shows will not air on the same streaming service. That means viewers will not necessarily have to choose between them.
The larger concern is whether Percy Jackson can attract the same level of attention once HBO’s marketing campaign begins.
Harry Potter remains one of the world’s most recognizable entertainment properties. Its reach extends beyond the books and films into theme parks, video games, merchandise and stage productions.
The reboot has also attracted curiosity because of the challenge of replacing the original cast, as well as the continuing controversy surrounding Rowling.
That combination is likely to keep the series at the center of entertainment coverage throughout its launch.
Percy Jackson Has Not Secured a Fourth Season
Disney has already committed to Season 3, meaning the series is not facing immediate cancellation.
Its future beyond those episodes remains less certain.
The original Percy Jackson series contains five main novels, leaving Disney with two more books to adapt after Season 3. Continuing the story would require renewals for The Battle of the Labyrinth and The Last Olympian.
Disney has not publicly confirmed that the series will reach either book.
Season 3 will therefore act as an important test for the franchise. Strong viewing figures and audience retention could persuade Disney to complete Percy’s original story, while weaker results could make another expensive renewal more difficult to justify.
Fantasy productions require large budgets for visual effects, elaborate sets and action sequences. The age of the show’s young cast also makes lengthy gaps between seasons increasingly complicated.
Disney attempted to address that problem by moving ahead with Season 3 early, allowing production to continue more quickly than it did following the first season.
That decision showed confidence in the series, but it did not guarantee that Disney would fund all five installments.
The company has become more selective with its streaming output as studios across Hollywood reduce spending and focus on franchises capable of retaining large audiences.
“They also tend to be very conservative about their decision-making and prefer to look at the most recent numbers before deciding how/when/whether to renew things,” Riordan also wrote of Disney’s approach (via Goodreads).
Percy Jackson has several advantages. The books remain popular, Riordan has built an extensive mythology around the characters and the Disney+ adaptation has a dedicated online fan base.
The question is whether that support will remain visible once Hogwarts returns.
Fans have already suggested that Harry Potter could expose weaknesses in Disney’s adaptation, particularly if HBO delivers a more detailed and faithful version of its source material.
No evidence currently suggests that Disney has formally decided to cancel Percy Jackson. The threat instead comes from what happens after Season 3 airs and Disney begins evaluating its performance.
By then, HBO’s reboot may have changed the streaming fantasy landscape.
If Harry Potter becomes the holiday season’s dominant television event, Disney will need to decide whether Camp Half-Blood is strong enough to continue competing.
