When searching for stocks that can multiply in value, it’s best to target industries with massive potential markets. In the healthcare sector, particularly the health insurance space, scale is not an issue. It is estimated that annual health insurance premiums in the United States reach as high as $1.6 trillion, and with an aging population, healthcare spending is expected to grow faster than GDP.
Oscar Health (OSCR) is an exceptional healthcare stock, steadily gaining market share through its technology-driven health insurance products. This fast-growing company is poised to deliver above-market returns for years to come.
The health insurance market changed following the enactment of the Affordable Care Act (ACA) in 2010, which created exchanges allowing individuals to purchase their own health insurance annually through regulated platforms. Despite a rocky start, approximately 20 million individuals now buy insurance through ACA exchanges, making this a significant segment of the industry.
Oscar Health, focused on the individual payer market, has become a major driver of this growth. Last quarter, total paid members enrolled in Oscar Health insurance plans reached 3.2 million, a more than 50% increase from the 2 million members in the same period a year ago. This growth rate far exceeds that of the overall ACA market, indicating that Oscar Health is significantly expanding its market share.
The reason lies in Oscar Health’s cloud-first digital platform, which delivers a superior customer experience, saving time and effort for all stakeholders in health insurance. The company is now pushing hard to shift the employer-led health insurance market toward individual premium payment plans. Such plans allow employers to subsidize employee health insurance but, instead of enrolling everyone in a one-size-fits-all plan, they let people use funds to shop on ACA exchanges, where they may choose Oscar’s insurance.
Health insurers under the ACA exchanges face strict regulations, with a maximum medical loss ratio of 80%, meaning only 20% of premium revenue can be used for administrative expenses and profit.
Through growing scale and technology-driven efficiency gains, Oscar Health has consistently reduced its administrative expense ratio. This is expected to bring about a significant profit inflection point in 2026. The company reported $700 million in operating revenue last quarter, and due to seasonal factors in medical utilization, its full-year 2026 operating income is expected to range between $250 million and $450 million.
Over the long term, as the company expands its national scale, the administrative expense ratio is expected to continue declining. Combined with rapid revenue growth—premium revenue has increased by 2,770% since 2021—Oscar Health could achieve substantial profit growth in the coming years. If revenue reaches $50 billion, a 5% profit margin would translate to $2.5 billion in profit, a target that could be reached within five years.
As long as Oscar Health continues along its current path of profit margin expansion and market share growth, its stock is likely to outperform the broader market for years to come.
Currently, the company has a market capitalization of approximately $6.6 billion. Based on the high end of its 2026 earnings guidance, the price-to-earnings ratio is 15x, but more importantly, that is only about 2.5 times the profit level I expect when its revenue reaches $50 billion. While that target will not be met in 2026, patient investors will be able to witness a massive profit inflection over the next decade, potentially leading to significant stock price appreciation for those who hold Oscar Health shares and never sell.
Summary: Leveraging its technology-driven health insurance platform, Oscar Health is rapidly expanding its membership and gaining market share in the $1.6 trillion and growing U.S. health insurance market, particularly within the ACA individual payer segment. By continuously lowering its administrative expense ratio through technological efficiency and economies of scale, the company is on track to reach a profit inflection point in 2026. At its current market capitalization relative to future earnings expectations, and if it continues to execute its strategy effectively, the company has the potential to deliver above-market returns over the long term.
