Market System: A Player's Guide
This is a plain-language guide to the market system — the set of rules that decide how much money your corporations actually make from what they produce. It builds on the raw Commodities market, and it's what ties your day-to-day pricing and investment decisions to your share price.
If you just want the formulas and constants, the Commodities reference has them. This page is the why and the what do I do.
The big idea
Older versions of the game paid your corporation a revenue number based mostly on market share and margins. The market system makes that revenue earned: prices react to scarcity, your goods have to find real buyers, and the capacity you build is a durable asset that shows up in your valuation.
It rolls out in tiers, switched on as a game world matures. Each tier that turns on adds one more layer of realism — and usually one more panel on your sector's detail page.
| Tier | What it does | What you see |
|---|---|---|
| Off | Legacy behaviour — revenue from share and margins. | Nothing new. |
| Realization | Scarce goods pay a top-line premium; gluts bleed revenue. | Higher/lower sector revenue as prices move. |
| Ledger | Book-keeping groundwork for the tiers below (no new player action). | Mostly behind the scenes. |
| Clearing | Your output must actually sell — cheapest sellers clear first. | A “% sold last turn” badge and pricing posture buttons. |
| Capital | Your growth budget builds owned capacity; output is gated by it. | A Capital panel with a per-unit economics breakdown. |
You don't turn these on — the game does. Your job is to understand each one so you can price and invest well when it's active.
Prices come from supply and demand
Every commodity has a price that moves each turn based on how much of it corporations produce (supply) versus how much they consume (demand). Scarcity pushes prices up; a glut pushes them down. The full mechanic — the 29 commodities, the curves, the three-tier blend — lives in Commodities. The market system is what turns those prices into your revenue.
Price realization — scarcity pays, gluts hurt
The first economic tier is price realization. Instead of only nudging your margin percentage, commodity prices now scale your top-line revenue:
factor = clamp((price / basePrice) ^ 0.5, 0.7, 1.5)
realizedRevenue = baseRevenue × factor
| Market condition | Realization factor |
|---|---|
| Balanced (price = base) | 1.0× |
| Mild shortage (2× price) | ~1.41× |
| Big shortage | up to 1.5× (capped) |
| Oversupply (0.5× price) | ~0.71× |
| Deep glut | down to 0.7× (floored) |
It's bounded and damped on purpose: realization alone moves your revenue at most −30% / +50% in a turn, and it uses last turn's prices so it can't oscillate wildly. The takeaway: producing something scarce is now genuinely rewarding, and dumping into a glut genuinely hurts. See Price Realization for the details.
Clearing — your goods have to actually sell
Once clearing is on, revenue is no longer handed to you — your output competes for real buyers. Each turn, demand fills the cheapest sellers first. Your realized revenue scales with the fraction of your output that actually sold (your “% sold last turn”).
This makes your pricing posture a real decision:
| Posture | What it does | Good when |
|---|---|---|
| Undercut | Price below the market to clear ahead of rivals. | You want to sell out; there's a glut. |
| At-market | Price at the going rate. | You're unsure; balanced conditions. |
| Premium | Skim for margin, accept the risk of unsold stock. | Genuine shortage — everyone sells out anyway. |
In a shortage, everyone sells out and premium pricing pays. In a glut, the undercutters clear and the skimmers are left holding unsold output — which drags down their revenue, valuation, and share price.
Cheapest sellers clear first
Buyers want 220 units this turn, but three sellers each offer 100. Demand fills the lowest-posture sellers first, so the premium seller is left holding unsold stock.
Your posture is the decision. Undercutting sells you out first (thinner margin, fuller sales). Skimming for a premium earns more per unit but risks unsold output in a glut. In a genuine shortage everyone sells out and the premium pays off. Your “% sold last turn” badge on the sector page shows how much of your output actually cleared.
There's also a physical limit: input throughput can gate output. If you can't get enough of the inputs your sector consumes, you physically can't produce (and therefore can't sell) at full tilt — no matter how you price.

Capital — capacity you own and maintain
Under the capital tier, your growth budget becomes investment. That investment builds productive capacity — a durable asset your company owns. The loop:
The capital loop
Reinvested earnings become capacity you own. Keep investing and capacity grows; stop and depreciation slowly erodes it. Your output is gated by the capacity you can support.
Depreciation pulls on the capacity box every turn — if investment stops, capacity (and therefore output) drifts down.
Unit economics
The sector page shows this breakdown so you can see the true economics of every unit — the capital charge is the cost of the capacity that unit was produced on.
Three things to internalise:
- Capacity gates output. You can only produce (and sell) up to what your capacity supports. Want more output? Invest to build more capacity.
- Depreciation erodes idle capacity. Capacity depreciates slowly every turn. A sector that stops investing gradually loses capacity — so reinvestment isn't optional if you want to hold your position.
- Unit economics are visible. The sector page shows a full per-unit breakdown — price − labour − inputs − capital charge = unit profit — so you can see the true economics of each unit, including the cost of the capacity it was built on.

What this does to your valuation
Because capacity is a real, owned asset, your company is valued for the durable capacity it owns — not just this turn's earnings. Valuation leans on tangible book (your liquid capital + sector value + an owned-capacity floor) weighted above raw earnings power.
That capacity floor is a depreciated high-water mark on the sector's going-concern value: it's seeded at the moment a tier flips (so it changes nothing at first) and only decays slowly if the sector is genuinely impaired. The practical effect: a company holds its value through a transient profit dip, because the assets it owns are still worth something even in a bad quarter. Your share price reflects owned assets + earnings power, not a single turn's profit. More on how shares are priced in Stock Market.
The transition is gentle — don't panic
When a new tier is switched on, nothing changes on the first turn. The flip turn itself is a no-op. From there the new mechanics fade in gradually over roughly 240 turns, so valuations drift rather than lurch.
This is deliberate. You get time to adapt your pricing posture and investment level as the new rules take hold — there's no overnight shock to your corporation or the market. If you see a tier go live, you don't need to do anything immediately; just start reading the new panels and adjusting over the coming turns.
What to actually do
- Chase scarce commodities. Realization and clearing both reward producing what's in short supply. Watch the Commodities prices and shift toward tight markets.
- Set your posture to your goal. Want volume and market share? Undercut. Want margin in a genuine shortage? Go premium. Check your % sold last turn each turn and adjust — unsold stock is lost revenue.
- Keep investing to hold capacity. Under capital, an idle sector shrinks. Keep the growth budget high enough to at least offset depreciation, more if you want to grow output.
- Read the sector panels. The Pricing panel, the throughput/Commodities panel, and the Capital panel each tell you why your revenue is what it is. They're your dashboard.
- Think in assets, not just this turn. A dip in profit isn't a collapse if you own real capacity — and rivals who stop investing are quietly getting weaker.
