Chevron vs. Occidental Petroleum: Which Oil Stock Is a Better Buy in 2026?

Fluctuating oil prices and the global transition to cleaner power are creating a complex environment for energy investors in 2026. Chevron (NYSE:CVX) and Occidental Petroleum (NYSE:OXY) are both large, well-established energy companies, but deciding between the two requires weighing stability against innovation.

Chevron is an integrated giant with operations spanning the entire globe and a very robust balance sheet. Occidental Petroleum is a more focused explorer that is betting its future on massive carbon capture projects and domestic production. Both companies are major players, but they offer different risk-and-reward profiles for investors.

The case for Chevron

Chevron is an oil and gas major that also operates a low-carbon business. It manages everything from exploration and drilling to refining and marketing its own fuel products. It uses Hess Midstream (NYSE:HESM) to manage its midstream needs and meet massive natural gas delivery commitments worldwide.

In FY 2025, revenue reached nearly $184.4 billion, 4.6% lower than the previous year. Despite the lower revenue, the company reported net income of nearly $12.4 billion for the period. This resulted in a net margin of about 6.7%, reflecting the impact of fluctuating commodity prices on its bottom line.

As of its December 2025 balance sheet, the debt-to-equity ratio was approximately 0.3x. This metric compares total debt to the value of shareholder equity, indicating how much the company relies on borrowing. The current ratio, which measures the ability to cover its immediate financial obligations using its short-term assets, was roughly 1.2x, while free cash flow reached nearly $16.6 billion.

The case for Occidental Petroleum

Occidental Petroleum focuses heavily on oil and gas exploration while building a massive presence in carbon management. The company relies on Western Midstream Partners (NYSE:WES) for essential transportation and processing services. Its strategy includes developing direct air capture technology through specialized ventures to remove carbon dioxide from the atmosphere.

During FY 2025, the company generated revenue of approximately $21.6 billion. It was 20.3% lower year over year, highlighting the sensitivity of its business model to market prices. Net income for the fiscal year was roughly $2.4 billion, yielding a net margin of about 11%.

On its December 2025 balance sheet, Occidental reported a debt-to-equity ratio of approximately 0.7x. A higher ratio in this category indicates the company uses more debt to finance its operations and growth. The current ratio was nearly 0.9x, and the company generated roughly $4.1 billion in free cash flow, which is the cash remaining after paying for operations and capital improvements.

Risk profile comparison

Chevron faces significant risks from commodity price volatility, which is often driven by geopolitical tensions and global production levels. The company also deals with operational hazards such as well blowouts or spills, for which it is largely self-insured. Additionally, integrating a massive acquisition like Hess poses challenges to meeting production targets and achieving cost savings.

Occidental is highly sensitive to price fluctuations in oil and natural gas, which are beyond its control. The company carries a higher level of indebtedness, which could limit its flexibility if economic conditions worsen. Furthermore, its heavy investment in carbon management involves technological uncertainty and depends on the development of new commercial-scale markets.

Valuation comparison

Occidental Petroleum offers a lower entry point based on future earnings estimates, but Chevron remains highly competitive when looking at its total sales volume.

Which stock would I buy in 2026?

Chevron is among the largest integrated oil and gas companies in the world. Because its operations span upstream exploration, midstream transport, and downstream refining, its cash flows are less vulnerable to commodity-price volatility than those of a pure-play oil exploration company.

Chevron's $53 billion acquisition of Hess last year has significantly expanded its asset base, especially in Guyana's massive offshore Stabroek Block.

The oil giant projects 10% annualized growth each in earnings per share and adjusted free cash flows each through 2030 at a Brent crude oil price of $70 per barrel. It is committed to dividends and regular share repurchases. Chevron has increased dividends for 39 consecutive years. In a latest major development, Chevron has committed $7 billion to Venezuela.

Occidental is a predominantly upstream producer, so its cash flows are tied more closely to commodity price that Chevron's. Occidental Petroleum stock has been an underperformer in recent years, but things have turned around this year after the company started repaying debt that it piled on with the 2019 Anadarko acquisition and the 2024 CrownRock acquisition.

It recently sold its chemicals division, OxyChem, to Berkshire Hathaway (NYSE:BRKA)(NYSE:BRKB) for roughly $9.7 billion. Those proceeds went into repaying debt, and Occidental is in a much stronger financial position now. Once the company hits its debt target, I expect bigger dividends and share repurchases. Berkshire Hathaway is a major stakeholder, with a 26.5% stake in Occidental.

While Occidental is making every effort to strengthen its balance sheet, Chevron already has one. A rock-solid asset base, strong cash flows, and dividend discipline make Chevron a better oil stock to buy for 2026 and beyond.
