Last updated: May 13, 2026. Trading values fluctuate constantly with each update. This guide focuses on trading mechanics, value tracking tools, and scam prevention — strategies that remain useful regardless of current prices.
Understanding the PS99 Trading Economy
Pet Simulator 99 has one of the most robust player-driven economies on Roblox. Unlike most games where items are bought from NPCs, PS99 relies on player-to-player trading for the best pets, enchants, and items. Understanding this economy is essential for getting strong pets without spending real money.
The Value System
Pets in PS99 are valued using two main metrics:
| Metric | Description |
|---|---|
| RAP (Recent Average Price) | The average price that a pet has recently traded for. Updated in real-time based on actual trades. |
| Gem/Diamond Value | The actual currency value that players demand in trades. This can differ from RAP due to supply, demand, and hype. |
Important: RAP is a reference point, not an absolute truth. Popular pets often trade above RAP, while flooded-market pets trade below it.
Pet Variants and Value
The same pet can have dramatically different values based on its variant:
| Variant | Value Multiplier | Notes |
|---|---|---|
| Normal | 1x (base) | Standard hatched pet |
| Golden | ~4x base | Created by fusing 3 normal pets |
| Rainbow | ~8x base | Created by fusing 3 Golden pets |
| Shiny | Varies (10x+) | Special event or trading variant |
Event-exclusive pets (limited-time eggs, seasonal events) also hold their value significantly better than standard pets because they cannot be obtained outside the event window.
Best Value Tracking Resources
As of May 2026, these are the most reliable value tracking websites:
| Website | What It Tracks | Update Frequency |
|---|---|---|
| Cosmic Values | Huge, Titanic, Gargantuan pet values | Daily |
| Traderie PS99 Values | Live prices with demand indicators | Daily |
| PS99Values | Trade calculator with Titanic/Huge/Garg prices | Daily |
| Big Games DB | Official database with RAP and existence counts | Real-time |
| PetSimXValues | Live RAP values and pet existence counts | Daily |
Always check multiple sources before making a trade. Values can differ between trackers, especially for newly released pets.
Where and How to Trade
Trading Plaza
The Trading Plaza is the central hub for in-game trading, located in the Spawn World. Here you can:
- Browse player booths — other players set up shops with pets for sale
- Set up your own booth — display items you want to trade or sell
- Initiate direct trades — approach another player and open a trade window
Personal Trades
Direct player-to-player negotiations. These happen anywhere in the game world. You approach another player, click “Trade,” and both parties select what they are offering.
Traderie (External Marketplace)
Traderie (traderie.com/pet-simulator99) is a community-moderated marketplace for PS99. Benefits include:
- Verified transactions reduce scam risk

How to Get the Best Deals
Rule 1: Know the Value Before You Trade
Never enter a trade without checking the current RAP and value list for every pet involved. A pet you think is worth 1B gems might actually be worth 10B — or 100M.
Rule 2: Trade Up, Not Sideways
The fastest way to build value is through a series of trades:
- Start with what you have (pets, enchants, potions)
- Trade for something slightly more valuable
- Repeat until you reach your target pet
Even small “trade ups” of 10-20% compound quickly.
Rule 3: Buy During Downtime
Pet values fluctuate with:
- New updates — new pets flood the market, lowering existing pet values
- Events — event-exclusive pets spike during the event, then drop afterward
- Weekends — more players online means more competition and higher prices
- After school hours — the player base surges, driving up demand
The best time to trade is during weekdays, right after a new update when prices are in flux.
Rule 4: Sell What You Do Not Need
Every potion, flag, fruit, enchant, and duplicate pet has value. Sell items you do not need in the Trading Plaza to accumulate gems for bigger purchases.
Scam Prevention Guide
Common Scams to Watch For
| Scam Type | How It Works | How to Avoid |
|---|---|---|
| Fake RAP | Scammer shows you a fake value screen | Always check values yourself using the tools listed above |
| Quick Switch | Scammer swaps the pet at the last second | Double-check the trade window before accepting |
| “Trust Trade” | Scammer asks you to give your pet first, promises to send theirs after | Never trust trust trades. Use simultaneous exchange only |
| Wrong Variant | Scammer trades a Normal pet when you agreed on a Rainbow one | Verify the variant (Golden, Rainbow, Shiny) in the trade window |
| Fake Middleman | Someone pretends to be a trusted middleman | Only use verified middlemen from official Discord servers |
| Overpay Lure | Scammer offers way too much to make you excited, then changes the deal | If it seems too good, it probably is. Stay calm and verify |
Red Flags
- The trade partner is rushing you to accept
- They refuse to let you check values
- They offer a “special deal” that you need to decide on immediately
- They ask you to trade outside the Trading Plaza
- The pet they are offering has an unusually low RAP for its rarity
What to Do If You Get Scammed
Unfortunately, BIG Games does not restore scammed items. Your best options are:
- Report the player through Roblox’s reporting system
- Share the scammer’s username on community Discords to warn others
- Learn from the experience and be more careful next time

RAP stands for Recent Average Price. It tracks the average price that pets have recently traded for in actual player trades. Use it as a reference point to determine if a trade is fair.

Always check live RAP values before every trade. Never do “trust trades.” Verify pet variants in the trade window before accepting. If a deal seems too good to be true, it probably is a scam.
