Palantir Surges 1.47% on $10.66B Volume—Fourth-Highest Trading Day as Defense Contracts Spark Institutional Frenzy

Palantir Technologies (PLTR) surged 1.47% on October 7, 2025, with a trading volume of $10.66 billion—the fourth-highest on the day. The AI analytics firm’s shares saw robust institutional participation as strategic infrastructure contracts with U.S. defense agencies were confirmed, signaling renewed demand for its data integration platforms.

Analysts noted that recent regulatory clarity on AI governance frameworks bolstered investor confidence in Palantir’s core government contracts. A key tender win for cybersecurity modernization at the Department of Homeland Security, announced earlier in the week, reinforced expectations of sustained revenue growth through 2026. Short-term traders also capitalized on the stock’s elevated volatility, with options activity showing a 40% increase in put/call ratio imbalances.

Backtesting a high-volume basket strategy from January 1, 2022, to October 7, 2025, would require daily rebalancing of 500 stocks. However, current tools limit testing to single-ticker strategies or event-driven analyses. Alternative approaches include narrowing focus to a single asset (e.g., SPY on days with top 5% volume) or exporting raw volume/price data for external portfolio calculations in Python/Excel. Full implementation remains constrained by system capabilities at this time.
