Palantir’s Growth Engine Humming, But Insider Exits and London Block Weigh on Sentiment

Palantir Q1 revenue up 85% to $1.63B, US sales doubled, but stock pressured by London police contract veto, $43M insider sales, and Trump trades.

Palantir’s first-quarter numbers were dazzling — revenue surged 85% year-over-year to $1.633 billion, and US sales more than doubled with a gain of 104%. The company lifted its full?year 2026 growth forecast to 71%. Yet the stock is struggling to hold its ground, caught between a string of headwinds that range from a blocked London police contract to a wave of insider selling and new political distractions.

The most immediate drag is the decision by London’s Mayor to veto a roughly £50 million contract between the Metropolitan Police and Palantir. The Mayor’s Office for Policing and Crime (MOPAC) rejected the deal on the grounds that the Met had failed to run a sufficiently competitive procurement process and had not made a convincing case for value for money. The package was split into two tranches — £25.3 million for 2026/27 and an optional £24.8 million extension for the following year. Had it gone through, it would have been Palantir’s largest police contract in the UK, using the company’s software to automate parts of criminal intelligence analysis.

MOPAC left the door open for a revised bidding process, so the rejection is not necessarily final. But the episode underscores a broader risk for Palantir’s government business: procurement authorities are increasingly demanding competitive tenders, robust privacy safeguards and clear economic justifications for big-ticket AI contracts. Any future UK public?sector deals will now face tougher scrutiny, and the failure to close this one — despite clear operational need — sends an unwelcome signal to investors.

Meanwhile, the company’s own leadership has been cashing in shares. On May 20, 2026, several executives filed mandatory disclosures of large stock sales. President Stephen Cohen sold nearly 320,000 shares at prices between $132.95 and $136.61, netting about $43.5 million. Chief Technology Officer Shyam Sankar disposed of shares worth roughly $22.5 million, and Chief Revenue Officer Ryan Taylor sold another $2.67 million. All transactions were executed under pre?arranged 10b5?1 trading plans and were officially tied to tax obligations from the vesting of restricted stock units. Taylor still holds around 200,000 shares, so management retains meaningful skin in the game. Still, the sheer size of the sales — Cohen alone pulled out over $43 million — adds a layer of noise that retail investors find hard to ignore.

That noise was amplified by Donald Trump’s first?quarter 2026 financial disclosure. The filing listed more than 3,700 separate transactions with a total value between $220 million and $750 million — a volume and pace that market observers have compared to algorithmic hedge fund strategies. Most concerning for Palantir bulls: the shares were reportedly bought just before Trump posted praise on Truth Social about the company’s “great war?fighting capabilities.” Representatives of the Trump family insist the holdings are in a blind trust designed to eliminate conflicts of interest, but ethics watchdogs are still examining the trades under the STOCK Act. The episode injects a political variable into Palantir’s narrative that no amount of commercial growth can fully neutralise.

Analysts remain split on valuation. At a price?to?earnings ratio of roughly 154, Palantir is one of the most expensive stocks in the market. Freedom Broker and Rosenblatt maintain price targets of $230 and $225 respectively, betting on sustained hyper?growth. Cantor Fitzgerald is far more cautious, with a target of $138 — close to where the stock currently trades. Long?term projections for 2030 paint a picture of $30.4 billion in revenue and $15.2 billion in profit, which would imply a share price of around $254 assuming growth rates between 45% and 71%. But as analysts at Trefis caution, such scenarios depend on uninterrupted hyper?growth and a clean ethical record in sensitive government contracts — both of which are now under pressure.

The technical picture offers little comfort. On Friday, the stock closed at €117.96, roughly 15% below its 200?day moving average and down about 18% year?to?date. The relative strength index (RSI) sits at 70.5, putting it in overbought territory — a signal that could mean further near?term downside. The US markets are closed Monday for Memorial Day, so the first regular trading day of the week is Tuesday. The macro calendar turns important on Wednesday, May 28, when the Bureau of Economic Analysis releases the second estimate of first?quarter GDP along with April income and spending data, including the PCE inflation gauge. High?multiple growth names like Palantir tend to be sensitive to such releases. After that, investors will turn to the company’s virtual annual general meeting on June 3.

For now, the fundamental story remains compelling: record Q1 revenue, accelerating US commercial adoption, and a raised guidance for the year. But the stock is being squeezed by insider sales, a blocked London contract, and a political disclosure that adds unwanted uncertainty. Whether the growth engine can outrun the noise is the question that will define Palantir’s next move.
