Which movie has biggest opening week in 2026?

According to the latest prediction market data for the query “Which movie has biggest opening week in 2026?”, traders have formed a strong consensus.

Currently, Avengers: Doomsday is dominating the market with an overwhelming 58% chance of winning. Spider-Man: Brand New Day follows in second place at 42%, while The Super Mario Galaxy Movie sits in third with 1.8%. The betting volume for this specific market has already reached $152.1K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• Avengers: Doomsday (58%): Currently commanding the highest probability, Avengers: Doomsday is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 58¢, signaling a high degree of market conviction. This contract alone has generated $64.2K in volume.

🥈 Tier 2: The Primary Challengers

• Spider-Man: Brand New Day (42%): Positioned as the most viable alternative, Spider-Man: Brand New Day maintains a 42% chance of resolving true. Its “Buy Yes” shares currently trade at 42¢.
• The Super Mario Galaxy Movie (1.8%): Sitting in third place with a 1.8% probability, the market shows measured skepticism toward The Super Mario Galaxy Movie, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes The Odyssey (1.6%), Toy Story 5 (1.4%), and Dune: Messiah (1.2%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like The Hunger Games: Sunrise on the Reaping are still attracting notable interest.

This market will resolve according to the title of the movie which grosses more domestically on its opening week than any other movie in 2026. The “Weekly Box Office Performance” table on the page for the relevant movie on https://www.the-numbers.com/box-office will be used to resolve this market once the values for the opening week are final (i.e. not studio estimates).

This market will resolve to "Yes" if the relevant movie grosses more on its domestic opening week than any other movie in 2026. Otherwise, this market will resolve to "No".

Please note, this market will resolve according to the The Numbers figures provided under Weekly Box Office Performance for the opening week, regardless of whether domestic refers to only the USA, or to USA and Canada, etc.

Resolution will be based specifically on the figures provided for this movie's opening week.

If another movie's opening week box office performance surpasses that of the named movie after numbers for both are finalized, this market may immediately resolve to "No".

If this movie's opening weekend box office performance ties with any other's, the movie whose title comes first in alphabetical order will win.

If there is no final data available by January 31, 2027, 11:59 PM ET, another credible resolution source will be chosen.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome Spider-Man: Brand New Day currently trades at 42%, but our AI places its Fair Value at just 37.1%. This creates a large negative EV Gap of -4.9%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies The Odyssey as the premium value opportunity on the board. While the market only assigns it a 1.6% trading probability, our AI’s Fair Value assessment sits at 33.9% — yielding an impressive +32.3% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include Toy Story 5 (EV Gap: +21.8%) and Dune: Messiah (EV Gap: +18%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
