States see disappointing tax revenue from legal sports betting Kendall Baker, Axios · April 22, 2019 at 12:59 pm Six states have legalized sports betting since the Supreme Court’s monumental decision last May, but New Jersey is the only one exceeding revenue expectations. Why it matters: These disappointing results are part of a “growing consensus that legal sports betting may not bring the windfall that economic forecasters predicted only a few months ago,” the New York Times‘ Timothy Williams reports. By the numbers: West Virginia has collected only a quarter of the monthly tax revenue it projected, and Pennsylvania and Mississippi have collected only half. Rhode Island has done even worse, bringing in $50,000 per month after predicting they’d bring in almost $1 million. Delaware is meeting projections, but it’s thanks in large part to a football-betting operation that’s been around since 2009.
