Buying the Future: How Battery Giants Quietly Set the Price of Your Car Somewhere out of sight, the price you will one day pay for an electric car is already being decided. It is not by carmakers, and not at a dealership, it is with long-term contracts between battery makers and the companies that supply their raw materials. One of these was reported recently; 17.2 billion dollars, without much explanation of what it actually was. It is worth understanding, because deals of this kind now shape the cost of nearly every electric car on the road, and almost nobody outside the industry has ever heard of them. This specific deal prompted this piece. It is a long-term supply agreement, or what in the commodities world is called an offtake agreement. An offtake agreement is a promise, signed years in advance, that one company will buy a fixed quantity of something from another company over a set period, at terms both sides agree to now. C CATL is Contemporary Amperex Technology Co., Limited, a Chinese company and the largest maker of electric-vehicle batteries in the worldATL has promised to buy 3.05 million tonnes of cathode material from a supplier called Ronbay between 2025 and 2031. That is roughly 610,000 tonnes a year, every year, for six years. The total value is put at 17.2 billion dollars. Basically CATL gives up the freedom to shop around each month, and in exchange it gets a guaranteed seat at the table for six years. Why a company would tie itself down like this The natural question is why a business would want to remove its own flexibility. The answer is that raw material markets are violent, and the thing CATL is buying sits at the heart of every battery it makes. Cathode material is made largely from lithium, and lithium prices swing wildly. In the space of a couple of months around the turn of 2026, the price of battery-grade lithium carbonate jumped by more than seventy per cent. A manufacturer that buys everything on the open market lives at the mercy of those swings. One quarter the batteries are cheap to build, the next quarter the same battery costs far more, and there is nothing the company can do except pass the cost on or absorb it. Neither is comfortable when you are trying to sell millions of identical products at a predictable price. An offtake agreement takes that uncertainty off the table. By fixing volumes and agreeing pricing in advance, CATL can plan its costs years ahead. It knows the material will arrive. It knows roughly what it will pay. It can promise its own customers, the carmakers, stable prices and reliable delivery, because it has stabilised the thing underneath. In an industry where the battery is the single most expensive part of an electric car, controlling that cost is close to controlling the business. There is a second, sharper reason, and it is the one that makes this particular deal interesting. CATL signed the contract while lithium prices were near their peak, which sounds like the worst possible moment to commit. Most buyers would wait, hoping prices fall. CATL did the opposite, and it did so deliberately. When prices are high and everyone is scrambling for material, suppliers are nervous about the future and willing to offer long-term certainty in exchange for a guaranteed buyer. That is exactly when a large player can negotiate a price below the going rate, precisely because it is offering something suppliers value: six years of guaranteed demand. It is counter-intuitive, but it is the logic of a company big enough to think in decades rather than quarters. What the supplier gets out of it The risk is really at Ronbay’s side. So why diod they get into this agreement? Ronbay is the supplier, and until recently it was not even in this business. It used to make a different kind of cathode material, the nickel-based chemistry used in premium batteries. Seeing the market shift towards the cheaper iron-phosphate chemistry known as LFP, it changed direction and started building LFP capacity, partly by buying another company that already had some. The CATL contract is the reward for that gamble. A guaranteed buyer for six years gives Ronbay something priceless: the confidence to invest. This is basically the key dynamic of every offtake agreement. A supplier will not spend billions building new mines, refineries and factories on the hope that someone might buy the output. The numbers are too large and the risk too great. But a signed contract from a buyer the size of CATL changes the maths entirely. With guaranteed demand in hand, Ronbay can go to its banks, raise money, and build the capacity needed to deliver 610,000 tonnes a year. The contract secures supply for CATL AND It funds the creation of that supply in the first place. That is also where the danger sits. Ronbay currently produces a fraction of what it has promised. It has committed to scaling up enormously, while posting losses in the short term because building all that capacity costs money before it earns any. The Shanghai stock exchange took one look at the announcement and formally asked the company to explain how it could possibly deliver. High reward comes with high risk, and a supplier that over-promises and under-delivers can unravel a deal like this. The contract is a promise, and promises can break. Why this is not just a big number It would be easy to file this under "large companies sign large contract" and move on. The reason it is worth understanding is that the contract is a signal about how the whole industry now works. For most of the modern commodities era, battery makers bought materials the way you might buy petrol: as needed, at whatever the price was that day, through short agreements tied to market indices. That approach suited a smaller industry. It does not suit one building batteries by the gigawatt-hour for a world switching to electric cars and grid storage at speed. When you need material on that scale, buying it piecemeal leaves you exposed, and your rivals who have locked theirs in will out-compete you on cost and reliability. So the leading players have started treating supply as strategic infrastructure. They are signing multi-year, multi-billion agreements to wall off the material they need before anyone else can reach it. CATL's deal is the largest example so far, but it will not be the last. Every time a giant removes six years of demand from the open market, the companies left buying at the gate face a tighter, pricier market. The rational response is to sign your own long-term deal, which tightens the market further. The behaviour feeds on itself. The knock-on effects reach all the way to the cars people buy. The chemistry CATL is stockpiling, LFP, is the cheap and durable one that makes affordable electric cars possible, which is good news for buyers. But the same deals concentrate power in a very small number of hands. When one or two companies control both the batteries and the materials behind them, the carmakers that depend on them become price-takers. They do not control the most expensive part of their own product. A brand that has secured its supply can price an affordable electric car with confidence. A brand that has not is exposed to every swing in the lithium market. This is becoming the normal way the battery industry secures its future, and in doing so it is quietly deciding who will be able to build affordable electric cars, and who will be left buying at the gate.

The MIT breakthrough in direct lithium extraction looks promising on paper, but I've seen several DLE technologies fail to scale commercially. What's different this time? Anyone with direct experience in DLE pilot programs willing to share insights?

Given the recent DOE announcement and China's tightening export controls, I'm curious what the community thinks about realistic timelines for U.S. self-sufficiency in rare earth processing. MP Materials is making progress at Mountain Pass, but we're still years away from having full separation and refining capacity domestically. What are the biggest bottlenecks you see?

With DRC export restrictions pushing prices higher, I'm looking at cobalt-exposed equities. But the shift to LFP batteries makes me cautious about long-term demand. Would love to hear perspectives from both the bull and bear side.
