Who will win Best Actor at the 2027 Oscars? Live Odds and Polymarket Predictions

Oscar season's Best Actor race has settled into a genuine two-man contest, and Polymarket traders have priced it about as close as it gets. The market asks a simple question for each nominee — will they win Best Actor at the 99th Academy Awards — and right now, Tom Cruise and Matt Damon are tied at the top of the board.

For those unfamiliar, Polymarket is a leading prediction market platform where users trade on the probability of real-world events. Unlike a critics' guild predictions column or an awards pundit's gut call, Polymarket odds reflect the collective wisdom of traders putting real money behind their predictions — making it one of the more responsive real-time gauges of how the Best Actor race is actually shifting as precursor awards roll in.

Live Polymarket Odds: Who will win Best Actor at the 2027 Oscars?

The embed below shows live, real-time Polymarket odds for Tom Cruise's contract in this market. Unlike a standard preview article, the odds you see here are always current — no need to search elsewhere for the latest numbers.

Cruise's “Yes” contract trades at 27¢ on Polymarket, with “No” at 74¢ — putting him in a flat-footed tie with Matt Damon, who also sits at 27%. The month-long chart shows how that tie came together: Cruise climbed steadily from the mid-teens in early August up into the high-20s, while Damon's line tells a much more dramatic story — his contract sat near zero for the market's early days before jumping almost vertically to the high-20s in a single move, the kind of pattern that usually reflects a specific catalyst like a strong festival reception or an early precursor nod. Behind them, Andrew Scott and John Malkovich have spent the month trading places in a tighter race of their own for third.

This market has traded roughly $98,460 in total volume, with Damon's contract alone accounting for over $30,000 of that — more than any other nominee, including the co-favorite Cruise. That's scheduled to close on March 14, 2027, around the date of the ceremony. Robert Pattinson also appears further down the board, though his current odds weren't fully visible in this snapshot.

How Polymarket Works for Oscar Award Markets

Polymarket operates as a prediction market where contracts are priced between $0 and $1, representing the implied probability of an outcome occurring. A “Yes” contract on Cruise priced at $0.27, for example, implies roughly a 27% probability that he wins Best Actor — based purely on what traders are collectively willing to pay.

This mechanism makes Polymarket odds fundamentally different from a critics' guild prediction column. Traders have a direct financial incentive to be accurate rather than expressive, which is why prediction markets have historically served as fast, responsive gauges of how an awards race is actually developing as the season's precursor events play out.

Per the market's resolution rules, this market resolves to “Yes” for whichever actor is announced as the winner of Best Actor at the 99th Academy Awards; every other nominee's contract resolves to “No.” Only one actor across the full field can settle “Yes.”

What Drives Polymarket Odds on the Best Actor Race?

Polymarket odds on an awards-season market like this one are influenced by a range of factors that traders continuously incorporate into their positions:

• Precursor award wins: Results from the Golden Globes, SAG Awards, and Critics' Choice Awards are often treated as the strongest leading indicators for how Academy voters will lean.
• Critical and festival reception: Strong reviews out of festival premieres can shift a performance's perceived momentum well before nominations are finalized.
• Campaign visibility: For-your-consideration screenings, press tours, and public appearances during the voting window can move sentiment quickly.
• Narrative and career context: A veteran actor's career arc, or a long-overdue narrative around a nominee, can meaningfully shift how traders price their chances relative to the raw performance.
• Film-level buzz: A nominee's odds are also shaped by how the film itself is performing in the broader awards conversation, including its own Best Picture chances.
