Ten Largest US Online Casino Jackpots

Notable Online Jackpots in 2026
The sizable progressive jackpots continue to make new millionaires in 2026.
Here’s just a few of the notable online winners that have happened this year.
Hard Rock Bet Casino New Jersey has already handed out three jackpots of at least $1.9 million in 2026 thanks to its Hard Rock Jackpots progressive system.
The first came on May 11 when a lucky winner brought in $1.94 million on Bag the Swag: Hold & Win. A month later, on June 4, a lucky NJ resident won $1.94 million on Hot Rod Hog. Then, on Independence Day, a Hard Rock online record was set when a player won $2.10 million on Silver Lux – Seven Spins Hold’em Respin.
Currently, Hard Rock has another Mega Jackpot building in New Jersey. It is up over $2.5 million as we speak, so the lucky winner will hold the new Hard Rock online jackpot record. It’s possible it could even reach into the top 10 all-time.
DraftKings Casino keeps a running tab of its online jackpots on its website. It claims to have issued over 125 prizes over $1 million in its history.
Along with some prizes over $3 million already in 2026, DraftKings Casino has also handed out a $2.28 million prize on March 5 on the game Double Jackpot Bullseye. On Feb. 12, a lucky winner in Pennsylvania collected $2.16 million playing Ultimate Fire Link Olvera Street.
