Are digital rips legal in Texas?
Texas has no law written specifically about digital rips, and rip apps currently operate there under their own terms.
Texas is a common home for prediction-market and DFS customers because sportsbooks can't operate here. That makes Texas one of the most important markets for rip apps, and a likely early market for any sportsbook that launches rips through a non-betting product.

The national picture
No court or state attorney general has ruled on whether randomized digital repacks are gambling. Lawsuits over card breaks at Whatnot and Fanatics Live are pending in California. If anything changes for Texas, we'll update this page.
