Palantir stock closed at USD 177.64 on the Nasdaq on September 18, 2026, marking a 0.79% gain for the session. The shares traded between an intraday low of USD 172.00 and a high of USD 177.75, with reported volume of about 39.30 million shares. That close left the stock modestly above some recent intrinsic value estimates, suggesting a market price slightly richer than certain fair value models.
September 18, 2026 in numbers
Palantir Inc. (ISIN US69608A1088, Nasdaq: PLTR) added 0.79% on September 18, 2026, as the Nasdaq session ended with the shares at USD 177.64. Market data for that day show an opening print near USD 177.18, a high of USD 177.75 and a low of USD 172.00, with roughly 39.30 million shares changing hands in regular trading. According to analysis cited by Simply Wall St, a commonly referenced fair value estimate of around USD 171.06 sits slightly below that USD 177.64 close, framing the latest level as a stretch above that particular model rather than a discount. Broader market data for September 18, 2026 indicate that the Nasdaq benchmark also ended higher that day, so Palantir’s advance came against a supportive tech backdrop.
Today’s setup for Palantir
Into today’s session on September 21, 2026, investors are watching valuation debates and ongoing artificial intelligence enthusiasm as context for Palantir’s share price. Recent commentary from outlets such as NAI500 has highlighted that Palantir’s revenue nearly doubled over the past 12 months while the stock price remained roughly flat, underscoring how earlier valuation excesses were gradually absorbed by fundamentals. This backdrop means that any new company-specific announcements or sector-wide artificial intelligence developments today could be interpreted through the lens of whether the current USD 177.64 level on September 18, 2026 still looks stretched compared with updated growth expectations.
