DraftKings and Flutter Entertainment have shown significant stock performance in November, with DraftKings rising by 24% and Flutter by 19%, both outperforming the S&P 500. Analysts at MoffettNathanson project that the online sports betting market in the U.S. will primarily be dominated by these two companies, with FanDuel (Flutter) and DraftKings expected to maintain a combined market share of 80%. This trend reflects the impact of expanding iGaming and sports betting laws across various states, which have contributed to their growth. The ongoing competition suggests that smaller sports betting applications may survive if they adopt effective strategies, according to DraftKings' CEO.
