Sometimes the EV goes above 1.0 and there are several groups of people who closely monitor lotteries all over the US to spot this event. When it does happen, which is very rare, they do calculations on the expected impact, viability and if their conclusions are good, swoop in and buy hundreds of thousands of tickets. They have people printing tickets for an entire day. They pay stores to stay open late. It's a tactical operation. Sometimes the jackpot is so anomalously big that the general public can't buy enough tickets to bring it back down below 1.0.
