The Bunker: the complete business guide

The Bunker has been a pillar of GTA Online money-making since Gunrunning arrived in 2017, and it still earns its place in 2026: a full upgraded stock sells for around GTA$1,050,000 and climbs toward GTA$1.5 million with high-demand bonuses in busier sessions. It is also the classic trap for new owners, because unupgraded it is genuinely bad, and sold at the wrong stock level it strands solo players with convoys they cannot finish.

This guide is the version that works: the right purchase, the two non-negotiable upgrades, the supply loop, solo-safe selling and what the research track is actually for. Figures are checked against current tracked values as of early August 2026.

Step 1: buy the right bunker

• Buy from Maze Bank Foreclosures. Chumash and Farmhouse are the classic picks for sitting close to the action; Paleto Forest is cheap and costs you the difference in driving forever
• The bunker location changes your commute, not your income, so buy for geography and nothing else

Step 2: the two non-negotiable upgrades

• Equipment upgrade, GTA$1,155,000, and staff upgrade, GTA$598,500, both from the laptop
• Do not judge the Bunker before these are in: unupgraded production is slow enough to make the whole business feel broken, because it is
• Upgraded, the stock and research speeds roughly double, and every number in this guide assumes you have them

Step 3: set the staff and the supply loop

• Assign staff to manufacturing for money; put them on research only when you are actively chasing an unlock, or fast-track research with cash and never think about it again
• Buy supplies for GTA$75,000 a full bar rather than stealing them, the time maths is not close
• If you own an Arcade, the Master Control Terminal resupplies the Bunker remotely, which turns the whole loop into a menu visit

Step 4: sell solo-safe

• The golden solo rule: sell early and often. A part-filled bunker keeps the delivery to a single vehicle, and a full one can spawn a multi-vehicle convoy on a timer that one player cannot beat
• Full stock is worth around GTA$1,050,000 upgraded, rising toward GTA$1.5 million with high-demand bonuses when more players share the session
• Watch the weekly events: Bunker sell bonuses of 1.5x and 2x come around regularly, and a saved full stock on a bonus week is one of the best paydays in the passive game

Step 5: use the research track once

• Research unlocks the Gunrunning arsenal: weapon liveries, the explosive rounds tier, and vehicle upgrades for the update hardware
• Fast-tracking with cash is expensive but honest about what your time is worth; grinding it via staff is free and slow
• Once the unlocks you care about are done, set staff fully to manufacturing and never split them again

The reference layer

Where the Bunker really sits in 2026: it is the strongest of the classic passive producers and the natural second layer after the Acid Lab, with one warning attached. Its sell missions are the most crew-hungry in the business game at full stock, so the solo version of this business is deliberately selling smaller and more often, trading peak payout for guaranteed completion. It also matters beyond its own income: the Bunker feeds Sporting Goods into the Nightclub warehouse, which is reason enough to own one even if you rarely sell from it directly.

Where it fits

Acid Lab first for the floor, Bunker second for scale and the Nightclub feed, Nightclub third to stack it all passively, heists for the spikes. The full business programme and the heists comparison live on the online desk at sixcentral.co.uk/online, on the site and in the SixCentral app.

Buy near the city, upgrade before judging, buy your supplies, sell before full. Six wars worth of guns leave that hillside every week, and now yours will actually get paid for.
