CS2 Case Odds: Official Drop Rates for Every Rarity

TL;DR: every official CS2 weapon case uses the same odds. You get a Mil-Spec (blue) 79.92% of the time, Restricted (purple) 15.98%, Classified (pink) 3.20%, Covert (red) 0.64%, and a knife or gloves 0.26%, which is roughly 1 in 385 cases. Those numbers don’t change from case to case, they don’t improve the more you open, and the price of the case has nothing to do with them.

The Official CS2 Case Drop Rates

Valve published these odds in 2017, after China required game publishers to disclose loot box contents and probabilities. They carried over unchanged from CS:GO to Counter-Strike 2 and apply to every standard weapon case.

Notice the pattern: each step up is about five times rarer than the one below it. That ratio is why the vast majority of openings land on a blue, and why a red feels like an event. If the color names are new to you, our CS2 skin rarity guide covers every tier.

What “1 in 385” Actually Means

The 0.26% gold chance is the most misunderstood number in CS2. “1 in 385” is an average, not a countdown. Every case is an independent roll, so case number 384 has exactly the same 0.26% chance as case number 1. Nothing builds up between openings.

How many cases until a knife?

• 266 cases gives you about a 50% chance of at least one gold.
• 385 cases gives you about 63%, not 100%. More than a third of players who open that many still won’t see a knife.
• About 1,150 cases gets you to a 95% chance.

Plenty of players hit a knife in their first ten cases. Plenty open a thousand and never see one. Both outcomes are normal at these odds.

StatTrak Odds

Any skin from a weapon case can also roll as StatTrak. Valve has not published a StatTrak rate, but the community figure, based on large samples of openings, is about 1 in 10. Treat it as a well-supported estimate rather than an official number. StatTrak is a separate roll from rarity: a StatTrak blue is still a blue.

Knives vs Gloves

The gold slot holds either knives or gloves, depending on the case. Most cases have a knife pool; specific glove-era cases put gloves in that slot instead. The 0.26% is the chance of hitting the gold slot at all. Which knife or glove you get, and its float and pattern, is decided after that. That is where finishes like Doppler phases and blue gems come in, and why two golds from the same case can be worth wildly different amounts.

What the Odds Mean for Your Wallet

On Steam, opening a case means buying a key, which costs $2.49 in USD, plus the case itself on the market. Since about four in five openings return a Mil-Spec, and most Mil-Specs are worth far less than a key, the average Steam opening returns less than it costs. That isn’t an opinion about case opening; it’s what the odds table implies.

The useful number to think about is expected value (EV): the average value of everything a case can drop, weighted by its odds. If a case costs more than its EV, you lose on average over many openings. Short-term luck can swing either way, which is why one great night or one terrible one tells you very little.

How Odds Work on Case Sites

Third-party case sites don’t use Valve’s table. Each site builds its own cases and sets the odds for every individual item, which is why the same site can offer a cheap case with a 1% shot at something big and an expensive one built around a single knife. Three things are worth checking on any site:

• Per-item odds are shown before you open, not hidden behind a rarity color.
• Results are provably fair, so you can verify a roll was fixed before you clicked. Our guide to legit case sites explains how that works.
• The house edge is reasonable. We compare sites in lowest house edge CS2 case sites.

On CaseBattles, every case lists the odds for each item, and every result can be verified. If you want to test how odds feel before spending anything, start with the free daily case.

Weapon Cases Only

The table above covers weapon cases. Souvenir packages and sticker capsules use different rarity structures, so don’t apply these percentages to them. The same goes for the Weekly Care Package and other in-game drops: those aren’t case openings and follow their own rules.

How to Read a Case’s Odds in Practice

When you look at any case, official or on a site, run the same quick check. First, find the chance of the top item or tier. Second, find what most openings actually return, which on an official case is a Mil-Spec four times out of five. Third, compare the case price with that typical result, not with the best drop on the banner. A case that mostly returns skins worth a fraction of its price only makes sense if the rare hits are worth it to you, and you can afford the many openings it takes to see one.

Three Myths About CS2 Case Odds

“Cases are due to drop after a dry streak”

No. Each opening is independent. A long run of blues doesn’t raise your next chance by any amount.

“Older or rarer cases have better odds”

No. Old and new official cases share the same tier odds. An old case may hold more valuable skins, which raises its EV, but the chance of each color stays the same.

“Opening at a certain time helps”

No. There’s no time-of-day, server or account factor in the published odds.

Bottom Line

The CS2 odds table is short and fixed: 79.92 / 15.98 / 3.20 / 0.64 / 0.26. Know those five numbers, remember every opening is a fresh roll, and judge any case by its expected value rather than its best drop. If you want odds you can read item by item, compare the best cases to open or learn how case opening works first.
