Since October 22, 2025, five Covert skins can be traded up into a knife or a pair of gloves in Counter-Strike 2. It was one of the biggest changes the skin economy has seen. Pricempire data at the time showed more than $1.7 billion leaving the market in under 24 hours.
A year later, the question players still ask is simple: does a knife trade-up pay?
The short answer is no. Data from the CS2 trade-up calculator at cs2tradeup.gg, checked on November 10, 2026, covers all 204 normal knife contracts across the 43 weapon cases. Not one of them had a positive expected value at marketplace prices. The median contract lost 31.3% of what went in.
How does a knife trade-up work?
A knife trade-up takes exactly five Covert (red) skins and returns one knife or one pair of gloves. Before the update, the only way to bring a new knife into the game was to open a case, at odds of 0.26%, or about 1 in 385.
The rules are short:
- Inputs: five Covert skins from weapon-case collections. Coverts from map collections have no knife pool and don't work.
- Pool: the result comes from the case of one of your inputs. Each input gives its case a 20% share.
- Odds: inside a case, every knife and glove has the same chance. Pools range from 13 items (7.7% each) to 65 items (about 1.5% each).
- StatTrak: all five inputs must be normal, or all StatTrak. A StatTrak contract gives a StatTrak knife, and gloves drop out of the pool.
- Mixing: three Coverts from one case and two from another split the roll 60/40 between the two pools.
So you always get a knife or gloves. What you can't control is which one, and most pools are full of cheap finishes.
What does the data say?
Every case was checked at every input wear, which gives 204 contracts. Inputs and results were both priced at the lowest marketplace listing on November 10, 2026.
Measure | Result |
|---|---|
Contracts checked | 204 (43 cases × input wear) |
Contracts with a positive expected value | 0 |
Median result per contract | −31.3% |
Cheapest contract | $110.55 |
Closest to break-even | −1.7% |
The cheapest contract is five Battle-Scarred AWP Chrome Cannon skins from the Kilowatt Case. It costs $110.55 and returns $60.37 on average, a loss of 45.4%. The Kilowatt pool has 13 items, and only one of them is worth more than the inputs, so the chance of profit is 7.7%.
Cheap inputs don't make a good contract. The five contracts closest to break-even all cost more:
Inputs (5×) | Case | Cost | Expected value | Result | Chance of profit |
|---|---|---|---|---|---|
Prisma | $218.35 | $214.56 | −1.7% | 39.3% | |
Prisma 2 | $220.55 | $214.56 | −2.7% | 39.3% | |
Fever | $175.30 | $164.22 | −6.3% | 35.7% | |
Breakout | $728.65 | $679.43 | −6.8% | 23.1% | |
Dead Hand | $220.40 | $197.61 | −10.3% | 27.3% |
Steam Market prices tell the same story. One of the 204 contracts is positive before fees, and none are after Steam's selling fee. The numbers refresh every three hours on the live knife trade-up stats page.
Why do knife trade-ups lose money?
There are three reasons, and they stack.
- The inputs are priced for it. Coverts from cases with a knife pool are bought for trade-ups. Their price climbs until a contract is worth less than it costs.
- Most of the pool is cheap. A pool might hold one or two expensive finishes and a dozen ordinary ones. The expected value follows the ordinary ones.
- Selling costs money. You pay a fee when you sell the knife, and the lowest listing is usually more than you actually receive.
When can a knife trade-up still make sense?
A negative expected value doesn't make every contract a bad idea. There are three honest cases for doing one.
- You want any knife from that pool. If a random finish is fine, a contract can cost less than buying a knife from the same pool outright.
- You can find low-float inputs cheaply. With the lowest floats of each wear, 29 of the 204 contracts would turn positive. The catch is that low-float Coverts cost more than the cheapest listing.
- You accept the expected loss. Treat it as a purchase with a known average cost, not as an investment.
Be careful with StatTrak contracts. On paper, 21 of 164 StatTrak knife contracts look positive. Many of them rest on a single expensive listing in a thin market, which says little about what the knife would really sell for.
How do you check a contract before you sign it?
- Start with the pool, not the price. Look at how many items the case has and what the ordinary finishes sell for.
- Compare cost with expected value. A $110 contract that returns $60 is worse than a $218 contract that returns $214.
- Use the real floats. The input floats decide the wear of the knife, so enter the floats you can actually buy.
- Add the selling fee. Set the fee of the marketplace where you plan to sell.
- Look at the chance of profit. Expected value is an average. A 7.7% chance of profit means you lose money 12 times out of 13.
