What is the Polymarket Promo Code ACTION Offer?

The Polymarket promo code ACTION gives new users a $50 trading bonus after a qualifying $20 first deposit, which is a $30 upgrade over the previous offer. The Polymarket referral code ACTION is the same code under a different name; both terms are fully interchangeable on the platform and either works at sign-up.

Polymarket is a CFTC-regulated prediction market app where users buy and sell event contracts priced between $0.01 and $1. Each cent reflect one percentage point of implied probability. For example, a contract at $0.54 implies a 54% chance of that outcome. Contracts that resolve in your favor pay $1 per share; those that don't settle at $0. You can also sell your position at any point before final resolution if prices move in your favor mid-game.

The $50 bonus expires 30 days from issuance and cannot be withdrawn. It must be used to trade on Polymarket markets.

Spurs vs. Knicks Game 4: Polymarket Market Analysis (8:30 p.m. ET, ABC, Madison Square Garden)

The series storyline entering Game 4 of the NBA Finals is intriguing. New York traveled to San Antonio and won both games despite the Spurs leading in both games near the end of regulation. San Antonio then came to Madison Square Garden and won Game 3 115-111. The Knicks lead 2-1 but their home floor was not the advantage it was supposed to be for Game 3. Victor Wembanyama controlled the paint and De'Aaron Fox was a key offensive contributor.

Current Polymarket win probability for Spurs vs. Knicks Game 4

  • San Antonio Spurs: 47% — approximately $0.47 per share
  • New York Knicks: 54% — approximately $0.54 per share

Here's how to utilize your $50 trading bonus tonight:

A $50 trade on New York at $0.54 per share buys around 91 shares. If the Knicks hold home court and go up 3-1, those shares settle at $1 each and return $91.31 for a $41.31 profit.

The same $50 on San Antonio at $0.47 buys approximately 104 shares which returns $54.69 in profit if the Spurs even the series at 2-2 and reset the NBA Finals dynamic. The Spurs are slightly undervalued given their Game 3 performance. A 47% price on a team that just won at MSG feels like a market that hasn't fully processed the previous game.
