As the final quarter of 2025 approaches, the stock market is offering opportunities for investors seeking to turn modest stakes into potential millionaire-makers from companies poised for outsized growth.
While mega-cap names like Nvidia, Apple, and Tesla continue to dominate headlines, Finbold turned to OpenAI’s ChatGPT-5, which instead spotlighted three lesser-known players that could capture significant momentum in the months ahead.
Innodata (NASDAQ: INOD)
The first pick was data engineering company Innodata (NASDAQ: INOD). With demand for AI tools and training data surging, Innodata has posted strong revenue growth and raised its full-year guidance.
For the second quarter, the company reported earnings of $0.20 per share, beating the estimate of $0.11 and marking an 81.8% surprise. This compares to break-even earnings a year earlier. Revenue reached $58.39 million, up from $32.55 million a year ago and above analyst expectations of $56.37 million.
ChatGPT also highlighted analysts’ views, pointing to strengthening margins and improving profitability as reasons to stay bullish. However, much of the company’s success depends on a few large customers, leaving the stock vulnerable to volatility.
By press time, INOD stock was trading at $62.56, ending the day up 2.6%. Year-to-date, the stock has rallied nearly 60%.
Serve Robotics (NASDAQ: SERV)
Another AI-selected stock is Serve Robotics (NASDAQ: SERV), a small-cap firm building fleets of autonomous sidewalk delivery robots.
Serve Robotics reported Q2 2025 revenue of $642,000, up 46% from Q1, fueled by nearly 80% quarter-over-quarter delivery volume growth. The company also maintained a strong liquidity position with $183 million in cash as of June 30, providing runway through the end of 2026.
Fleet revenues rose $117,000, a 55% sequential increase, supported by new operations in Atlanta and the upcoming expansion into Chicago.
At the same time, the company plans to deploy 2,000 units by year-end 2025 while expanding partnerships across food and retail delivery. If Serve proves the economics of scaling robots in the “last-mile” market, ChatGPT emphasized that the upside could be substantial.
However, with high cash burn and limited revenue at present, the path forward remains risky, hinging on execution, regulation, and investor patience.
At Friday’s close, SERV traded at $12.13, up more than 6%. Year-to-date, however, the stock is still down 17%.
In summary, ChatGPT noted that while both companies carry significant risks, they also offer the kind of asymmetric upside potential that defines “millionaire-maker” opportunities.
