Polymarket Traders Overwhelmingly Expect Weak Supergirl Box Office Debut

The warning signs for the Supergirl box office continue to pile up.

Industry tracking has already suggested DC Studios’ next theatrical release could open anywhere from the mid-$40 million range to the mid-$50 million range domestically. Now bettors putting real money on the outcome appear to be siding with the most pessimistic projections.

According to Polymarket’s opening weekend market for Supergirl, 62% of traders currently expect the film to open below $52 million domestically. At the opposite end of the spectrum, only 8% are betting on an opening above $70 million.

While prediction markets are hardly a perfect science, they do provide a fascinating look at where people are willing to put actual money behind their beliefs. Right now, the overwhelming majority of those bettors appear to believe Supergirl is headed for a disastrous debut.

Bettors Are Backing The Lowest Outcome Available

One of the most striking aspects of the Polymarket data is how heavily concentrated the betting has become around the lowest available threshold.

Current odds as of this writing show:

  • Under $52 million — 62%
  • $52 million to $58 million — 16%
  • Over $70 million — 8%

The market itself remains relatively small, but the trend is difficult to ignore.

Rather than clustering around the middle of industry projections, bettors have overwhelmingly gravitated toward the bottom end. That suggests many traders believe even the current tracking estimates may be too optimistic.

In other words, the people putting money on the outcome are not expecting a breakout success story over the final week before release.

Supergirl Is Drifting Into The Marvels Territory

The comparison DC fans probably don’t want to hear is The Marvels.

Marvel’s 2023 box office disaster opened to just $47 million domestically before becoming one of the most infamous superhero flops in modern Hollywood history.

The current low-end box office projection for Supergirl sits at $45 million, which is actually under the heinous opening of Marvel’s most notorious flop.

That comparison becomes even more uncomfortable when considering how much damage The Marvels inflicted on Marvel Studios’ reputation. The film became a symbol of declining audience interest in the superhero genre and raised serious questions about whether comic book movies still possessed the cultural dominance they enjoyed throughout the previous decade.

DC surely doesn’t want Supergirl entering those same conversations.

Toy Story 5 Could Create An Embarrassing Headline

The challenge for Supergirl extends beyond its own opening weekend numbers.

The film arrives just one week after Toy Story 5, which is expected to open significantly higher and could remain a major force during its second weekend.

Recent projections have suggested Pixar’s latest sequel could potentially generate enough business in its second frame to challenge Supergirl for the top spot at the domestic box office.

That would create an uncomfortable narrative for Warner Bros. Discovery and DC Studios.

A brand-new superhero movie losing its opening weekend to a family film already in its second week would immediately dominate box office headlines and reinforce concerns that audience enthusiasm for Supergirl simply isn’t where the studio needs it to be.

The Market Is Echoing Existing Concerns

For months, questions have surrounded Supergirl’s marketing campaign, audience awareness, and overall level of excitement. Recent tracking reports have repeatedly pointed toward a softer-than-expected opening weekend, while online discussion surrounding the film has often focused more on interviews and promotional controversies than excitement for the movie itself.

The Polymarket numbers appear to reflect those same concerns.

Rather than signaling confidence that Supergirl can outperform expectations, traders are overwhelmingly betting that the film lands near the bottom of its projected box office range.

Prediction markets aren’t always right. Surprise openings happen every year. But when more than half of bettors are backing the lowest available outcome and virtually nobody believes the film can clear $70 million, it becomes difficult to dismiss the signal entirely.

With release day rapidly approaching, Supergirl may still have time to change the narrative.

At the moment, however, people willing to put money on the outcome appear convinced that DC’s next big theatrical release is headed for a very weak opening weekend.
