Palantir Technologies (NASDAQ:PLTR<\/a>) stock is up 9% to $127.31 in midday trading on Wednesday, leading a broad AI-software rally after the company unveiled a sovereign-AI partnership with NVIDIA (NASDAQ:NVDA<\/a>). Palo Alto Networks (NASDAQ:PANW<\/a>) stock is riding the risk-on tape higher, up 4% to $355.40. <\/p>\n The move for Palantir stock caps a sharp reversal for a name that had been under pressure. Palantir shares remain down 28.5% year to date even after today’s pop, and the stock trades at a P\/E ratio of 130x. Palantir’s market cap now sits at roughly $304.6 billion. <\/p>\n NVIDIA Sovereign-AI Deal Ignites Palantir Stock <\/p>\n Palantir announced a partnership with NVIDIA this week to deliver secure “sovereign AI” for U.S. government agencies, critical infrastructure operators, and allies. Palantir is integrating NVIDIA’s Nemotron open AI models into its intelligent engine, enabling agencies to deploy frontier-level AI in secure, air-gapped environments while keeping sensitive data off public networks. <\/p>\n Customers can customize the models with their own data and retain ownership of the resulting model weights. Palantir’s Sovereign AI Operating System is built on its AIP, Foundry, Ontology, and Apollo products, aligning directly with its existing federal footprint. <\/p>\n Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks \u2014 and Palo Alto Networks didn’t make the cut.

NVIDIA stock, notably, is slightly lower on the day, showing the reaction is Palantir-specific rather than a chip-cycle catalyst. <\/p>\n Bull and Bear Cases on the Valuation <\/p>\n The valuation debate around Palantir stock has intensified into today’s rally. On June 16, Wolfe Research initiated Palantir stock at Peer Perform, calling its enterprise AI product portfolio best-in-class but citing premium valuation as a roadblock. Analyst Alex Zukin flagged net revenue retention of 150%, 85% year-over-year revenue growth. <\/p>\n Zukin also modeled a base-case revenue CAGR of 39% from 2026 to 2029 against a total addressable market over $385 billion. Palantir’s most recent Q1 2026 report showed revenue of $1.63 billion, up 85% year over year, and management raised full-year guidance. The bear case is straightforward: Palantir remains a high-multiple, richly valued name where any growth stumble can trigger a sharp derating. <\/p>\n Cybersecurity Peers Ride the Tape <\/p>\n Palo Alto Networks stock and CrowdStrike stock are participating in the broader AI-software bid rather than sharing Palantir’s specific catalyst. CrowdStrike (NASDAQ:CRWD<\/a>) shares are up 2% to $776.09, a smaller move as traders position ahead of the company’s 4-for-1 stock split, with split-adjusted trading beginning July 2. <\/p>\n Palo Alto Networks stock has been on a tear, up 93% year to date heading into today. Analyst sentiment is stacked bullish, with 44 Buy, 9 Hold, and 1 Sell ratings, though PANW stock now trades well above the analyst target price of $314.48 at a P\/E ratio of 294x. The cybersecurity lane is related to Palantir’s government software niche, but distinct. <\/p>\n What to Watch <\/p>\n A key question now is whether this week’s NVIDIA partnership translates into signed federal contracts for Palantir rather than headlines alone. The sovereign-AI push aligns with Palantir’s existing government footprint, yet the company’s premium multiple leaves little room for disappointment if deal flow proves slow to materialize. Any renewed cooling in the broad AI-software rally could also pressure high-multiple stocks such as Palantir, Palo Alto Networks, and CrowdStrike in tandem. <\/p>\n Investors can watch for whether Palantir stock holds its gains into the close, along with any follow-up commentary from federal customers on the NVIDIA integration. These are volatile, high-multiple names, and a single session doesn’t reset the long-term thesis for any of them. <\/p>\n Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks \u2014 and Palo Alto Networks didn’t make the cut.
