Key elements: movie title, record to beat, deadline (opening weekend

What is happening now

The Polymarket contract “Will Spider‑Man: Brand New Day beat Avengers: Endgame’s opening weekend record?” is asking whether the domestic opening‑weekend box‑office gross of a film titled Spider‑Man: Brand New Day will exceed Avengers: Endgame’s record of $357,115,007. The market’s end date is August 2 2026 23:59 UTC, which corresponds to the close of the three‑day opening weekend (July 31 – August 2 2026). As of the latest update (August 3 2026 18:23 UTC) the “Yes” outcome is trading at 0.999 (99.9 % implied probability) and the “No” outcome at 0.001 (0.1 %). The contract has attracted over $412 k in total volume, with $301 k traded in the last 24 hours, and remains in “expired_pending_resolution” status, awaiting the final box‑office numbers.

A search of publicly available sources shows no official announcement from Sony Pictures, Marvel Studios, or any reputable trade outlet confirming a Spider‑Man film titled Brand New Day slated for release in mid‑2026. The movie does not appear on Sony’s upcoming‑release calendar, Marvel’s phase‑wise slate, or major box‑office tracking sites such as Box Office Pro or The Numbers. Consequently, there are no analyst projections, trailer releases, or studio statements that could inform a realistic opening‑weekend forecast.

How the market is structured

This is a binary market with two mutually exclusive outcomes:

• Yes – resolves if the domestic opening‑weekend gross (including Thursday previews) for Spider‑Man: Brand New Day is strictly greater than $357,115,007.
• No – resolves if the gross is equal to or less than that figure, or if no credible data are available by the fallback deadline (August 9 2026 23:59 ET).

The resolution source is the “Weekend Box Office Performance” table on the movie’s The Numbers page (https://www.the-numbers.com/). If the figures are ambiguous, the market will stay open until both Box Office Mojo (https://www.boxofficemojo.com/) and The Numbers confirm finalized numbers. If no final data appear by August 9 2026, an alternative credible source will be selected.

Currently the “Yes” side dominates the order book at 99.9 % probability, while “No” sits at a mere 0.1 %.

Path to the leading outcome

For the “Yes” outcome to occur, the following must happen:

• Sony/Marvel must officially announce a Spider‑Man film titled Brand New Day with a wide theatrical release targeting the weekend of July 31 – August 2 2026.
• The film must generate strong pre‑release buzz (trailer views, social‑media engagement, critic previews) that translates into high advance ticket sales.
• Actual ticket sales reported by theaters (and aggregated by The Numbers) must surpass the $357.1 million threshold.

Given the historical performance of recent Spider‑Man releases (Spider‑Man: No Way Home opened with $260 M domestic, Spider‑Man: Across the Spider‑Verse with $120 M), beating Endgame’s record would require an unprecedented level of audience demand—comparable to the all‑time opening‑weekend champions (Avengers: Endgame, Avengers: Infinity War, Star Wars: The Force Awakens).

What could change the pricing

Several concrete developments could shift the market away from its current extreme bias toward “Yes”:

• Absence of an official announcement – If Sony or Marvel do not confirm a Brand New Day release by mid‑2025, traders would likely reassess the feasibility of a 2026 opening, driving the “Yes” price down.
• Release date shift** – Should the film be moved to a different window (e.g., holiday season or early 2027), the July 31‑August 2 2026 window would no longer apply, causing the market to resolve as “No” by default.
• Negative early indicators** – Weak tracking numbers, poor test‑screening scores, or a lack of major marketing spend would signal a lower‑than‑expected opening, reducing confidence in a record‑breaking gross.
• Competing releases** – A simultaneous blockbuster (e.g., a new Marvel or DC film) splitting the audience could suppress Brand New Day’s gross.
• Macro‑theatrical factors** – A prolonged industry strike, significant decline in theater attendance, or a resurgence of streaming‑first releases could depress overall box‑office performance, making the Endgame record harder to beat.
