Flutter Entertainment (NYSE:FLUT) is one of the most promising stocks with huge upside potential. On November 24, HSBC upgraded Flutter Entertainment to Buy from Hold with a price target of $228, down from $265. HSBC has identified a buying opportunity for the shares after the recent price decline. The firm reassured that although the US gaming market is maturing and slowing, the perceived risks in both the US and the UK appear to be overstated and already reflected in the current share price.

In its Q3 2025 earnings call, Flutter Entertainment reported earnings $1.64 per share, which was $1.14 higher than Wall Street estimates. The company was also able to generate revenue $12.75 million above guidance, totalling $3.79 billion and growing 16.84% year-over-year.

The company maintained its position as the number one online operator in both the US sportsbook and iGaming markets. US Revenue increased by 9% year-over-year. This growth was fueled by impressive iGaming growth of 44%, which offset a 5% decline in sportsbook revenue. The sportsbook faced challenges from customer-friendly sports results and heightened competitive intensity, particularly increased competitor generosity at the start of the NFL season. Despite this, the company achieved a 47% NGR market share in September.

Flutter Entertainment (NYSE:FLUT) operates as a sports betting and gaming company in the US, the UK, Ireland, Australia, Italy, and internationally.
