The Mosaic Company (MOS) Stock Forecast: What Could Drive It in 2026
Last updated July 2026
Short answer
What is actually driving The Mosaic Company (MOS) right now is Global crop-nutrient demand: Mosaic's core driver is worldwide demand for phosphate and potash, which is linked to planted acreage, crop prices, and farmer affordability. Revenue (TTM) is ~$12.4 billion. If that keeps playing out, the setup is favourable; the risk to it is mosaic is a cyclical commodity producer, so its earnings can swing dramatically with potash and phosphate prices and are exposed to sharp input-cost inflation in sulfur, ammonia, and natural gas. No one can predict where MOS trades, and Walnut does not publish targets, so treat this as a scenario, not a price target or prediction.
What could drive The Mosaic Company (MOS) higher?
1. Global crop-nutrient demand
Mosaic's core driver is worldwide demand for phosphate and potash, which is linked to planted acreage, crop prices, and farmer affordability. In early 2026 the company reported its highest phosphate sales volumes in about five years as deferred demand returned. Long-run demand growth for food and biofuels supports nutrient consumption, though it can pause when farm economics weaken.
2. Potash and Esterhazy productivity
Potash is Mosaic's steadier, lower-cost segment. The company held full-year 2026 potash guidance near 9 million tonnes, expecting output from the completed Esterhazy hydrofloat project to offset volume lost from the Carlsbad divestiture. Efficient, high-volume potash production is a key earnings anchor when phosphate margins are squeezed.
3. Brazil and premium products
Roughly a third of Mosaic's business flows through its South American Mosaic Fertilizantes operations, giving it distribution reach in a major growth market. The company is also pushing higher-value products such as MicroEssentials, which combine multiple nutrients in a single granule and can carry better margins than commodity fertilizer.
4. Input-cost spreads
Mosaic's phosphate margins depend heavily on the cost of sulfur and ammonia relative to finished-product prices. When these inputs surge, as they did in early 2026, margins compress and the company may curtail production. Managing this spread, including temporary plant idling, is central to protecting cash flow through the cycle.
What could weigh on MOS?
Mosaic is a cyclical commodity producer, so its earnings can swing dramatically with potash and phosphate prices and are exposed to sharp input-cost inflation in sulfur, ammonia, and natural gas. In early 2026 rising input costs pushed the company to a quarterly net loss and forced temporary curtailments at U.S. phosphate plants and idled some Brazilian SSP output, and it withdrew full-year phosphate production guidance. Global competition is intense, with OCP Group in phosphates and Belarusian and Russian producers in potash affecting prices and supply. Weather, weak farm economics, trade policy, currency moves (especially the Brazilian real), and regulatory or environmental costs at mining and processing sites add further volatility.

How to think about a MOS forecast

FAQ
What is the forecast for The Mosaic Company (MOS)?
+
No one can reliably predict where MOS will trade, and Walnut does not publish price targets. What is more useful is the setup: the drivers that could push The Mosaic Company higher and the risks that could weigh on it. This page lays out both so you can form your own view. Not a recommendation.
What could drive MOS higher?
+
The main growth drivers are Global crop-nutrient demand; Potash and Esterhazy productivity; Brazil and premium products. Whether they play out is the real question, not a guaranteed path.
What are the risks to MOS?
+
Mosaic is a cyclical commodity producer, so its earnings can swing dramatically with potash and phosphate prices and are exposed to sharp input-cost inflation in sulfur, ammonia, and natural gas. In early 2026 rising input costs pushed the company to a quarterly net loss and forced temporary curtailments at U.S. phosphate plants and idled some Brazilian SSP output, and it withdrew full-year phosphate production guidance. Global competition is intense, with OCP Group in phosphates and Belarusian and Russian producers in potash affecting prices and supply. Weather, weak farm economics, trade policy, currency moves (especially the Brazilian real), and regulatory or environmental costs at mining and processing sites add further volatility.
Will MOS stock go up in 2026?
+
Nobody knows, and anyone who says they do is guessing. The Mosaic Company's direction depends on whether the drivers above outweigh the risks, plus the broader market. Focus on the thesis and your time horizon rather than a single-year call.
Is MOS a buy?
+
That depends on your thesis, time horizon, and what you already own, not on a forecast. See the MOS "is it a buy?" page for a framework. Walnut is not an investment adviser.
Why did Mosaic report a loss in early 2026?
+
Mosaic posted a first-quarter 2026 net loss of roughly $258 million as surging sulfur and ammonia costs sharply compressed phosphate margins, even though phosphate sales volumes were the highest in about five years.
