York Space Shares Drop >10% After Short Seller Claim

York Space Systems stock fell over 10% on May 11, 2026, after Wolfpack Research announced a short position.
Wolfpack alleges 96% of York’s 2025 revenue depended on Pentagon’s SDA, which is being dissolved and lost Tranche 3 funding.
Pentagon budget documents show SpaceX’s Starshield selected for the new Space Data Network, with no competitive solicitation for a second vendor.
York’s CEO denied termination of the Transport Layer program; the company will hold its next earnings call on Wednesday.
