Palantir jumps over 3% toward its highest 2026 close

Palantir rose more than 3% on September 23, 2026, on track for its highest close of 2026, MarketWatch reported. The move extended a six-day run of about 10%. Shares remain below the $194.17 close from December 2025, per Dow Jones Market Data. I see a crowded run into old supply — the test is whether buyers clear it.
