Becoming a billionaire in Old School RuneScape (OSRS) isn't just about grinding endlessly-it's about working smart, staying ahead of the market, and using every game update to your advantage. Whether you're starting fresh or returning after a long break, this guide walks you through every stage of wealth-building, from your first 10 million RuneScape gold to your first billion.

Step 1: Profit from Game Updates

The single best way to make massive amounts of OSRS GP is by keeping up with game updates. When Jagex releases new content, prices skyrocket for related items. Farming day-one drops or supplying the materials in demand can net you millions in just hours.

For example, when the boss Yama was released, the demand for pineapple pizzas doubled overnight. Similarly, updates that rebalance combat or introduce new magic gear can make item prices surge. Staying informed means staying profitable-read every patch note carefully and anticipate what the community will rush to buy.

Even canceled content can lead to profit. When players suspected there would be no Leagues event for the year, discontinued League items in the main game (like Twisted Canes) rose tenfold in price.

However, speculative investing carries risk. Never put all your gold into a single item, and always account for Grand Exchange taxes. Diversify-invest in consumables like potions or ores when a new boss or skill is announced. For instance, copper ore saw huge spikes in price after the Sailing reveal.

Step 2: Making Your First 10 Million GP

Before you can invest, you need a foundation. Your first 10 million is the turning point-enough to start flipping items, upgrading your gear, and exploring profitable skills.

If you're free-to-play, it's admittedly tough. However, you can buy short membership packages via the RS3 mobile app. On Android, a one-day membership costs less than a dollar, and even a three-day pass unlocks money-making methods that are ten times better than anything free-to-play offers.

If you refuse to spend money, there are F2P methods like mining, smithing, or killing hill giants-but they're slow and repetitive. Once you gain membership, the real opportunities begin.

Recommended Starter Methods:

Looting: Visit areas like the Catacombs of Kourend, where players often leave valuable drops behind.

Silver Jewelry: Craft and enchant burning amulets, expeditious bracelets, or bracelets of slaughter for 1–2M GP/hour.

Crystal Keys: Combine loop and tooth halves-currently over 3M GP/hour depending on GE prices.

Processing Items: Poison dragon knives, tan hides, or break down bracelets of ether for passive profit.

Clue Scrolls: Easy and medium clues can yield 40k–160k per completion, and they're simple to do with low stats.

By testing out GE margins before diving into a method, you'll ensure consistent income instead of wasted time.

Step 3: From 10M to 100M – The Slayer's Path

Once you've hit 10 million GP, it's time to scale up. At this stage, you can afford better gear and start participating in higher-level money-making activities.

Skill-Based Income:

Thieving Buyers: Over 2M GP/hour if you stay on drop rate.

Hunter: Catching black chinchompas earns about 750k/hour.

Runecrafting: Still one of the most stable income sources for patient players.

Among all skills, Thieving offers one of the best balances between profit and enjoyment.

Slayer for Profit

Slayer remains one of the most consistent methods to grow your wealth. Unlocking bosses like Arax at level 92 Slayer yields 5M GP/hour or more. Many other Slayer bosses have similar potential, and higher-tier Slayer Masters can assign lucrative boss tasks like Vardorvis, earning 7M GP/hour.

Another fantastic mid-tier method is the Corrupted Gauntlet, which requires no gear or capital. Once you're familiar with it, you can make up to RS gold for sale 4M GP/hour just from drops.
