5. Interactive Brokers Group Inc. (NASDAQ:IBKR)

TTM Net Income: $1.04 billion

Interactive Brokers Group Inc. (NASDAQ:IBKR) is one of the most profitable growth stocks to buy. On June 1, Interactive Brokers introduced agentic trading by integrating directly with Claude, allowing clients to research stocks, analyze portfolio performance, and generate trade instructions using the AI platform. This secure integration enables users to connect their existing accounts through a certified connector marketplace, providing access to over 170 global markets without the need for additional accounts or shared passwords.

The system uses a “human-in-the-middle” design, ensuring that while the AI can process natural language queries (such as portfolio concentration or rebalancing needs), it cannot execute trades independently. Instead, all trade instructions are sent to a dedicated tab across IBKR platforms, where clients must manually review and approve them before they are submitted as official orders into the marketplace.

This feature currently supports equities and ETFs, with plans to expand to further asset classes soon. Furthermore, integrations for ChatGPT, Gemini, and Grok are undergoing certification. This launch complements Interactive Brokers Group Inc.’s (NASDAQ:IBKR) existing suite of AI tools, which includes natural language screeners, thematic investment searches, and automated news summaries, all designed to enhance investor decision-making.

2. Eli Lilly and Company (NYSE:LLY)

TTM Net Income: $25.28 billion

Eli Lilly and Company (NYSE: LLY) is one of the most profitable growth stocks to buy. On June 7, Eli Lilly’s oral GLP-1 medication, Foundayo (orforglipron), demonstrated significant efficacy in promoting weight loss for women across all stages of menopause. Results from post-hoc analyses of the ATTAIN-1 and ATTAIN-2 clinical trials, presented at the American Diabetes Association’s 86th Scientific Sessions, indicate that women taking the highest dose experienced substantial weight reduction regardless of whether they were pre-, peri-, or post-menopausal.

In the ATTAIN-1 trial, women achieved weight losses of up to 30.4 lbs (14.4%) in perimenopause and 28.2 lbs (14.1%) in post-menopause over 72 weeks. Similar trends were observed in the ATTAIN-2 trial, which included participants living with type 2 diabetes, where post-menopausal women saw weight loss of up to 27.8 lbs (13.6%). Additionally, participants across both studies reported meaningful reductions in waist circumference, suggesting a decrease in abdominal fat and associated cardiometabolic risks.

These findings address a critical gap in obesity care, as hormonal changes during menopause frequently accelerate fat accumulation and complicate weight management efforts. As a once-daily, non-peptide oral medication that does not require food or water restrictions, Foundayo offers a flexible treatment option for women navigating the biological challenges of this life stage.

Eli Lilly and Company (NYSE:LLY) is a healthcare company that develops human pharmaceutical products across cardiometabolic health, oncology, and immunology.
