NBA 2K25 has reintroduced the Auction House in MyTeam, a key feature for trading players and building your dream squad. However, accessing the Auction House is a bit different this year, as it’s tied to the new Rep System. This guide will walk you through the steps to unlock the Auction House and provide tips to speed up the process.

Step 1: Reach Gold Tier in MyTeam Rep

To unlock the Auction House, you need to progress through the MyTeam Rep System. Starting with Bronze, you'll need to work your way up to the Gold Tier to unlock the Auction House.

Here’s how the progression works:
- Bronze Tier: Entry-level.
- Silver Tier: Progresses naturally after completing objectives.
- Gold Tier: Unlocks the Auction House.

Reaching the Gold Tier will not only unlock the Auction House but also reward you with:
- A Team Creation Arena and Court Pack
- A Gold Ball

Step 2: Gain Rep Efficiently

The fastest way to gain rep and unlock the Auction House is by playing the Breakout game mode. Breakout allows you to choose the difficulty of the games, and the easiest way to grind rep is by selecting the Rookie difficulty.

Follow these steps:
1. Go to Breakout Mode: In Breakout, select Rookie difficulty to make games easier and faster.
2. Play Games: Choose game modes like Triple Threat or Clutch Time, where you face off against teams in a series of challenges. 
3. Repeat: Play as many Rookie games as possible, as each win gives you rep.

You can choose between playing offline or online. If you prefer online, go for Showdown or Salary Cap Domination.

Step 3: Unlock Additional Auction Slots

Once you've unlocked the Auction House, you’ll start with a limit of 20 auction slots. To increase the number of slots, continue leveling up your MyTeam Rep. 

Each new tier grants additional slots:
Emerald Tier:
1. Random Franchise Cards
2. x13 Converse Weapon OX Shoe Cards
3. Emerald Ball
4. +10 Cards to My Auctions

Continue progressing to unlock up to 100 auction slots as you reach the highest tiers.

Step 4: Maximize Rep with Double Rep

A great tip to speed up the grind is by activating Double Rep. Here's how to do it:
1. Head over to the park, where you can open packs.
2. Purchase any pack, such as the cheapest option (4500 MT), and this will activate 30 minutes of Double Rep. Make sure to activate this when you’re ready for a grind session.
3. With Double Rep active, focus on Breakout mode for maximum rep gains during your 30-minute window.

Step 5: Complete Rep Agendas

In addition to Breakout mode, completing Rep Agendas is another way to earn extra rep. These are specific objectives you can complete to boost your progression. Look for agendas that mention rep and aim to complete them naturally as you play.

For example:
- Tatum Points Agenda: Score 250 points with Jason Tatum across multiple games for a rep reward.
- Point Guard Points Agenda: Score a specific number of points with a point guard to earn rep.

Step 6: Be Aware of Auction House Changes

NBA 2K25 has implemented an Escrow System in the Auction House. This means that when you purchase or sell players, the game will hold your MT or cards for a brief period while 2K verifies the transaction. If the transaction is deemed invalid (for example, if you're suspected of buying or selling MT), you may face a ban.

Tips to Save Time
1. Stick to the easiest games in Breakout mode to grind quickly.
2. Only activate Double Rep when you’re ready to grind for a full 30 minutes.
3. Stay on top of Rep Agendas for easy bonus rep.

Unlocking the Auction House in NBA 2K25 takes some grinding, but by using the tips in this guide—playing Breakout on Rookie difficulty, completing Rep Agendas, and activating Double Rep—you can get there faster. Once you’ve unlocked it, you can start sniping cards, building your dream team, and working the Auction House to your advantage.
