CS2 Knife Trade Up: How the Five-Covert Contract Works, and What It Costs

The change shipped in the Counter-Strike 2 Update of 22 October 2025, under the heading [ CONTRACTS ]. It is short enough to quote in full:

Extended functionality of the "Trade Up Contract" to allow exchanging 5 items of Covert quality as follows: 5 StatTrak™ Covert items can be exchanged for one StatTrak™ Knife from a collection of one of the items provided. 5 regular Covert items can be exchanged for one regular Knife item or one regular Gloves item from a collection of one of the items provided.

Read it slowly, because every rule this page relies on is in those two sentences.

• Five inputs, not ten. The older contract tiers, from Consumer up to Classified, take ten skins and return one skin of the next rarity. The Covert contract takes five.
• All five must be Covert. Covert is the red-name rarity, the highest one a weapon skin can have. Before this update Covert was the top of the ladder; now it is one step below the gold items.
• The output is a knife or gloves. That is the gold "★" tier that used to come only from case openings or purchases.
• The pool comes from your inputs. The item is "from a collection of one of the items provided". You choose the collections by choosing the Coverts.
• StatTrak™ and regular are separate versions. StatTrak™ inputs lead to a StatTrak™ knife; regular inputs lead to a regular knife or gloves.

The word Valve uses is "exchanged". The five Coverts are consumed and one item comes back, exactly as with every other contract. Nothing about the earlier ten-skin tiers changed in this note; it extended the contract with a new top tier rather than replacing it.

The single most useful phrase in the patch note is "from a collection of one of the items provided". It means you cannot aim a knife trade up at any knife in the game. You can only reach the gold items tied to the collections your five Coverts came from.

In practice that turns the question around. Instead of asking "how do I trade up to a Butterfly Knife?", ask "which collections lead to a Butterfly Knife, and which Coverts belong to them?" Every weapon skin's collection is printed on its Steam Community Market listing and in its in-game inspect panel, so you can check each input before you buy it.

The cleanest case is a single-collection contract. If all five Coverts come from the Kilowatt Collection, every possible output comes from that collection, and the Kilowatt Case's gold item is the Kukri Knife. That is why the worked example below uses it: there is exactly one knife model in play, so the only unknowns are finish and wear.

Mixed contracts are where the official wording stops helping. If three Coverts come from one collection and two from another, the note says the result comes from "a collection of one of the items provided". It does not say how that collection is picked, or whether three inputs from one collection make it more likely than two from another. Some players assume the older contract's weighting carries over. Valve has not said so, and we are not going to state it as fact.

Gloves follow the same rule with one extra unknown. The regular version can return "one regular Knife item or one regular Gloves item", but the note does not say how the game chooses between a knife and gloves when a collection's gold pool has both, or what the odds are. If you specifically want gloves, note that the StatTrak™ sentence names only knives; gloves appear only in the regular version.

StatTrak™ gets its own sentence in the patch note, and it is narrower than people expect.

Five StatTrak™ Coverts return one StatTrak™ knife. That is the whole rule. The note does not mention StatTrak™ gloves, so do not run a StatTrak™ contract expecting gloves.

Five regular Coverts return a regular knife or regular gloves. Regular inputs do not produce a StatTrak™ output.

The note describes the two versions separately and says nothing about mixing StatTrak™ and regular Coverts in one contract. The site's trade-up float guide explains that the older ten-skin contracts do not allow that mix. Valve's October 2025 note does not restate it for the Covert tier, so the in-game contract screen is the place to confirm what it will accept.

The practical consequence is cost. StatTrak™ versions of a skin usually list above the regular version, so a StatTrak™ knife contract costs more to fill. For a feel of the gap on one skin we track, a StatTrak™ AK-47 Redline in Field-Tested lists at $58.29 against $24.80 for the regular one (lowest listings, 13 October 2026). That is a Classified rifle rather than a Covert, so treat it as an illustration of the premium, not a quote for your inputs.

This section is short on answers on purpose. Plenty of videos and calculators state these things with confidence. None of them comes from Valve, and we have not been able to verify them.

Float deserves a specific word, because it is the question we get most. Our trade-up float page works through the formula players use for the older ten-skin contracts. That formula is derived by the community from observed results; Valve has never published it. We have not seen evidence that the same arithmetic governs the five-Covert knife contract, and the patch note does not describe any float rule at all. So the honest position is that a knife's wear from a trade up is undocumented. Do not pay extra for low-float Covert inputs on the promise of a Factory New knife.

The same goes for finish odds. A collection's gold pool can contain cheap finishes and expensive ones, and the gap between them is often several times over. Without published probabilities, nobody can compute an honest expected value for a knife trade up. Any site that prints one is guessing, or describing its own data without saying so.

The Kilowatt Case is the simplest collection to price, because its gold pool is the Kukri Knife. Its two Covert skins are the AWP | Chrome Cannon and the AK-47 | Inheritance. On 14 October 2026 the lowest listings we found were $22.66 for a Field-Tested Chrome Cannon and $30.00 for a Field-Tested Inheritance. Those two input prices are a one-day snapshot and will move.

Now the other side of the trade. These are the lowest live listings for the Kukri finishes we track, refreshed 13 October 2026:

Read the two tables together. The cheapest way to fill the contract is $113.30. Any Kukri in the second table listed below that figure was cheaper to buy outright, with the finish and wear chosen by you. On the day this page was rewritten, that included the Safari Mesh at $35.89 and the Night Stripe at $43.31.

The contract only competes with buying if you are aiming at the finishes priced above the input cost, and accept that you do not know how likely you are to get one. Valve publishes no finish odds and no float rule for this contract, so we cannot tell you whether $113.30 of Coverts tends to return a cheap camo or a Fade. That is not a gap in our research; the information does not exist in any official source.

Two more costs belong in the sum. The five Coverts are gone once the contract runs, so you lose whatever you could have sold them for. And if you sell the Kukri on the Steam Community Market, Steam's 15% fee comes off the sale price: a knife listed at $82.35 returns about 85% of that to your wallet.

The Kukri Knife guide covers the finishes in more depth, and why CS2 knives are so expensive explains where the gold-tier prices come from.

There are now three in-game ways to end up holding a knife, plus trading with other players. They differ mostly in what you get to choose.

Buying is the only route where you choose the exact item. If a specific knife is the goal, it is also the only route with a known price. The cheapest knife guide walks through the bottom of the market family by family, and the best knives under $150 page covers the next step up.

The contract narrows the knife model down to the gold pool of your inputs' collections and nothing further. It suits someone who already owns Covert skins they would otherwise sell, more than someone buying five Coverts from scratch.

Opening cases is the most random. The gold tier comes up at roughly 0.26% per opening, which works out at around 385 openings on average, and each one costs a key plus the case. Our case opening odds page has the full distribution, and how much it costs to open a CS2 case prices a single opening. The knife you get is drawn from that case's whole gold pool, so the result can be worth far less than the spend.

Our view, after pricing the Kilowatt example: if you know which knife you want, buy it. Use the contract when you already hold Coverts from a collection whose knife you would be happy with in any finish.

The real contract made the fake ones more convincing, not less. The phrase "knife trade up" is now an official feature, which makes it ideal bait.

• Sites that clone the contract screen. The real Trade Up Contract runs inside the game, from your own inventory. A website that asks you to deposit five Coverts by trade offer so it can "run the contract" is not running Valve's contract.
• "Upgrade" and "knife contract" products. Offsite operations dress up their own games of chance in contract language. Their odds are set by the operator, not by Counter-Strike 2.
• API key theft. A "knife trade-up calculator" that asks you to sign in through a lookalike Steam page, or to paste in your Steam Web API key, is after control of your trades.
• Fake middlemen. Someone in a Discord server offers to run a knife trade up for you if you send them the Coverts. There is nothing to run on your behalf; the contract is in your own game client.

One rule covers almost all of them: no part of a knife trade up requires your items to leave your account before the contract runs.

If it goes wrong anyway, there is now an official route back for trades. Valve's 16 July 2025 Season Two: Episode One announcement introduced Trade Protected Items: if you lose control of your account or were the target of a scam by a bad actor, "you may reverse all Counter-Strike item trades from the last 7 days", using the trade reversal feature on your Steam account's Trade History page. Our CS2 skin scams guide covers what that changes and what it does not.

Before October 2025, "knife trade up" mostly meant something else: swapping small items for slightly bigger ones with other players, step by step, until the inventory is worth a knife. That practice still exists, and it is still slow.

Each step costs you a little, because the person on the other side needs a reason to accept, so nobody trades at exact market value. It takes many steps to climb from a few dollars to a knife, and every one of them means trusting a stranger. If you try it, learn what a fair offer looks like from our CS2 trading guides first, and check every item on the final confirmation screen.

The contract changes one thing for peer traders. Coverts now have a use besides being sold or displayed. Whether that changes their prices over time is a market question we will answer from our own price tracker data rather than guess.
