As of March 24, 2026, there are two active codes available for MLB The Show 26 that can be redeemed for Diamond Dynasty rewards.

Active Codes (March 2026)

• LOCKEDON: Redeem for a Locked On - Fan Giveaway Pack.
• JOMBOY: Redeem for a Jomboy Media - Fan Giveaway Pack.

While these packs are a great start, building a competitive Diamond Dynasty squad often requires a bit more capital. If you’re looking to pick up specific players from the marketplace without the long grind, you can find affordable MLB The Show 26 stubs over at SHANNENG. It’s a straightforward way to round out your roster so you can spend more time actually playing the game.

Here is a guide for farming MLB 26 stubs fast and safe.
