GraniteShares’ leveraged Palantir ETF PTIR is up about 3.7% on June 01, 2026, mainly reflecting renewed strength in AI‑linked growth stocks and supportive U.S. equity futures. The fund provides 2x leveraged exposure to Palantir, so upside in AI software and infrastructure, plus a still‑constructive broader market tone, is being magnified in PTIR’s price action despite no single stock‑specific catalyst for Palantir itself emerging today.
