Borderlands 4 Money Farming Guide: Fastest Ways to Get Rich on Kairos

Cash is everything in Borderlands 4. From endless respec fees to steep death penalties and those can’t-miss vending-machine legendaries, your wallet drains faster than a Vladof minigun. The planet Kairos also runs on a tougher economy than past games, so if you’re not farming efficiently you’ll always feel broke.

After testing community strategies across early, mid, and late game, we’ve rounded up the best, fastest, and most reliable methods to stack credits—whether you’re fresh off the story or grinding endgame.


1. Encore Machine Boss Farm – Best Overall Method

Moxxi’s Big Encore Machine is the ultimate money printer. It lets you instantly respawn and re-fight bosses or Ripper Drill Sites for a small fee, creating a non-stop loop of combat and profit.

How the Cash Loop Works

  1. Locate an Encore Machine near a boss arena or Drill Site.

  2. Pay the reset fee (scales with level, capping around 30–40k Cash).

  3. Defeat the boss, scoop the loot, and sell at the vending machines usually placed right beside the machine.

  4. Repeat. One purple-rarity item normally covers the fee—everything else is pure profit.

Best Bosses to Farm

  • Sidney Pointylegs – Prospects Drill Site, Fadefields. Drops The Swarm legendary grenade.

  • Bramblesong – Augur Mine, Terminus Range. Drops the high-value Convergence shotgun.

  • Splashzone – Coastal Bonescape, Fadefields. Quick early-game farm right next to a vending station.

Pro Tip: Use “Pick Up as Junk” during fights, then “Sell All Junk” at the vendor for lightning-fast turnover.

2. Stillshore Red Chest Exploit – Early-Game Cash Grab

If you’re fine with an old-school Borderlands trick, the Stillshore Chained Red Chest can be farmed for infinite loot with minimal effort. (Gearbox may patch this at any time.)

Quick Steps

  1. Fast-travel to Abandoned Post safehouse in Coastal Bonescape.

  2. Head southwest to activate the Stillshore checkpoint.

  3. Clear enemies and loot the chained chest on the second floor.

  4. Quit to main menu → Continue. Your inventory stays full, chest respawns.
    Repeat until your backpack is bursting.


3. Bounty Board Contract Farming – Steady Income for All Stages

Prefer variety? Grab contracts from Bounty Boards in safe zones for cash, XP, Eridium, and loot.

Efficiency Tips

  • Prioritize “Vile” bounties (targets with crystal growths) for bigger payouts.

  • Force a refresh: accept all contracts, abandon them, quit to menu, reload to reroll the board.


4. Smart Loot Management – Sell Smarter, Not Harder

Borderlands 4’s new Licensed Parts system makes even non-legendaries valuable.

  • Sell order: Purples → Blues → Greens. A single purple often covers an Encore reset.

  • Don’t hoard: Bank future-build gear in Faction Towns; sell everything else.

  • Purples can carry you through content, but duplicates or bad rolls = easy cash.


5. Advanced Money Tips

  • Death Is Cheap: Late-game death penalties (~10k) barely matter once you’re farming.

  • Replay Missions: Target quests with high cash rewards in their preview screen.

  • Fish for Loot: Bubbling water spots occasionally cough up sellable weapons—worth a quick cast.

  • Upgrade Backpack SDU: Bigger inventory = fewer vendor trips and more profit per run.

Conclusion: The Best Way to Get Rich

For sheer speed and reliability, the Encore Machine farm—especially at Sidney Pointylegs or Bramblesong—wins hands down. It’s intended game design, delivers legendary loot, and prints cash.

Whether you exploit, farm, or bounty hunt, you’ll never worry about ammo money, respec fees, or that surprise vending-machine legendary again.
