The private jet associated with Palantir CEO Alexander Karp is a 2002 Bombardier Challenger 604 with registration N814PS and serial number 5544. Based on current Challenger 604 listings and recent transaction benchmarks, the aircraft is likely worth about $4.5 million to $6.5 million.

A reasonable working value is approximately $5 million to $6 million. That estimate is far narrower than the earlier broad executive-jet range because the aircraft can be traced through its registration, serial number, operator history, and a previous sales listing.

Palantir separately reported spending $17.2 million during 2025 for use of an aircraft beneficially owned by Karp. That amount is an annual company expense, not the purchase price or current value of the Challenger 604.

The aircraft and the expense are different numbers.

TLDR: Karp’s identified Challenger 604 is likely worth $4.5 million to $6.5 million, while Palantir spent $17.2 million on aircraft use during 2025.

• Identified aircraft: 2002 Bombardier Challenger 604
• Registration: N814PS
• Serial number: 5544
• Current estimated value: $4.5 million to $6.5 million (at $30 per hour, earning that amount would take about 72 to 104 years of full-time work, before taxes)
• January 2020 asking price: $4.695 million
• Palantir’s 2025 aircraft expense: $17.2 million

What the aircraft is

Aircraft registration and aviation fleet records identify N814PS as a 2002 Bombardier CL-600-2B16, the certification designation used for the Challenger 604. The Federal Aviation Administration lists serial number 5544, two GE CF34 turbofan engines, a valid registration, and TVPX Aircraft Solutions as trustee. The current FAA registration record confirms the airframe’s age and identity.

The trustee name does not by itself identify the economic owner. Aircraft trusts are frequently used in business aviation for registration, financing, privacy, and regulatory purposes. Separate fleet records connect N814PS with Palantir Technologies. Ch-aviation lists Palantir as the operator for noncommercial Part 91 flights in its N814PS aircraft record.

A second aviation history database shows the aircraft entering Palantir’s fleet in October 2020 after previous registrations and operators. That registration history connects the same serial number, model, and tail number with Palantir.

Taken together, these records provide a stronger basis than guessing from Palantir’s annual travel expense. They identify a specific large-cabin business jet that can be compared with other Challenger 604 aircraft of similar age.

Karp’s Challenger 604

The most defensible July 2026 estimate is $4.5 million to $6.5 million (about 72 to 104 years of full-time work at $30 per hour). The lower end reflects older Challenger 604 aircraft with substantial hours or upcoming maintenance. The upper end fits well-equipped aircraft with strong engine coverage, updated avionics, refurbished cabins, and favorable inspection status.

GlobalAir currently reports an average Challenger 604 asking price near $5.6 million, with listings running from about $4.6 million to $7 million. Its current 604 inventory provides one of the clearest live market checks.

Controller shows Challenger 604 aircraft advertised from approximately $3.5 million to $6.95 million. Several aircraft close to N814PS in production year and accumulated hours sit near the middle or upper portion of that range. The current listing set also shows how maintenance programs and avionics upgrades can outweigh model year alone.

Business Jet Traveler reports an average asking price around $4.8 million and an average recorded sale price near $4.7 million. Its Challenger 604 market data supports a value near $5 million before adjusting for this aircraft’s present condition.

No public appraisal for N814PS was found. Its precise value would require current engine times, maintenance records, inspection status, cabin condition, avionics details, and damage-history checks.

The aircraft’s earlier $4.695 million listing

N814PS was offered for sale in January 2020 at $4.695 million (about 75 years of full-time work at $30 per hour). The Guardian Jet specification sheet identified it as a 2002 Challenger 604 with serial number 5544 and registration N814PS. At that time it had 6,950.9 total hours and 4,612 landings.

The listing also stated that both GE CF34-3B engines were enrolled in the GE OnPoint program. Engine-program enrollment can materially affect market value because buyers gain some protection from large scheduled or unscheduled engine bills. The aircraft also had a Honeywell auxiliary power unit, Collins Pro Line 4 avionics, ADS-B Out, and a 2017 exterior repaint. The archived Guardian Jet specification sheet shows the asking price and equipment.

The same aircraft was marketed through AircraftExchange at $4.695 million, providing an independent copy of the sales information in its archived aircraft listing.

A 2020 asking price is not the same as a completed sale price. It does, however, create a firm historical anchor. Current Challenger 604 market values have remained around that level or moved higher for well-maintained examples, which supports the present $4.5 million to $6.5 million estimate.

Purchase value vs Palantir’s expense

Palantir’s reported $17.2 million aircraft expense does not reveal what Karp paid for N814PS. The company’s 2026 proxy statement says Karp beneficially owns an aircraft used by him and other Palantir personnel for business travel. Palantir either reimburses Karp directly or buys hours through a third-party aviation company operating the aircraft.

The arrangement uses hourly rates reviewed by Palantir’s audit committee. The company states that the highest rate was at or below market rates for comparable charter aircraft. It also says the rates decline as annual flight hours increase. The full description appears in Palantir’s 2026 proxy filing.

Palantir incurred approximately $17.2 million for aircraft use in 2025, up from $7.7 million in 2024. The increase was $9.5 million, equal to about 123%. The two-year total was $24.9 million.

Cost measure	Amount	What it represents
Current aircraft value	$4.5 million to $6.5 million	Estimated market value of N814PS
2020 asking price	$4.695 million	Advertised price for the same airframe
Palantir 2024 expense	$7.7 million	Company cost tied to aircraft use
Palantir 2025 expense	$17.2 million	Company cost tied to aircraft use
Original new list price	About $27 million	Historic price for a new Challenger 604

The annual expense can exceed the aircraft’s current market value because it measures access and operation over many trips rather than ownership of the metal alone.

One year of use can cost more

A Challenger 604 requires two pilots, recurrent training, insurance, hangar space, scheduled inspections, engine reserves, parts, fuel, handling, and aircraft management. International missions add permits, navigation charges, crew hotels, catering, ground transportation, and positioning flights.

Palantir’s arrangement is also structured around charter-style hourly rates rather than reimbursement of fuel alone. A charter rate includes the operator’s fixed expenses, variable costs, availability commitment, administration, maintenance risk, and profit. Flights without Karp aboard may be needed to move the aircraft to his departure point or return it to its base.

Current Challenger 604 charter rates are commonly quoted near $7,500 to $9,500 per flight hour. A July 2026 charter reference places the aircraft in that range through its Challenger 604 rate guide.

Ownership modeling produces lower figures because it does not contain the same commercial margin or guaranteed availability. Liberty Jet estimates annual spending near $1.34 million at 200 hours and about $2.14 million at 400 hours. Those figures in its 604 operating budget cover a conventional ownership pattern, not Palantir’s disclosed arrangement or travel volume.

Costs beyond the aircraft’s value can include hourly charter payments, empty repositioning, crew, fuel, maintenance, engine reserves, insurance, hangar charges, management, security travel, international handling, and personal flights covered by the company’s security program.

Worked comparison

The gap between the aircraft’s estimated value and Palantir’s annual expense can be shown with one itemized calculation.

• Estimated aircraft midpoint: $5.5 million
• Palantir’s 2025 aircraft expense: $17.2 million
• Difference: $17.2 million – $5.5 million = $11.7 million
• Expense-to-value multiple: $17.2 million ÷ $5.5 million = about 3.1
• Monthly expense average: $17.2 million ÷ 12 = about $1.43 million

The calculation means Palantir’s 2025 expense was about 3.1 times the estimated market value of the aircraft. It does not mean the company bought the jet three times. It means the disclosed use arrangement generated annual costs far above the likely resale value of the underlying airframe.

High-use case. At $9,500 per hour, dividing $17.2 million by that rate gives about 1,811 hours before accounting for other expenses.

Lower-rate case. At $7,500 per hour, the same division gives about 2,293 hours.

Ownership case. A conventional 400-hour annual budget near $2.14 million would be less than one-eighth of Palantir’s 2025 expense. These comparisons are scenarios, not verified flight-hour records.

What the Challenger 604 originally cost

A new Bombardier Challenger 604 carried a list price near $27 million during its production era. The model was built from the mid-1990s through 2007 and became popular for transcontinental and international corporate travel. Current preowned prices are much lower because N814PS is now more than two decades old.

Air Charter Service places the historic new price at $27 million and current used values around $4 million to $6 million in its Challenger 604 profile.

That represents nominal depreciation of roughly $21.5 million when the $5.5 million estimated midpoint is compared with the original list price. The arithmetic is $27 million – $5.5 million = $21.5 million. The aircraft has retained about 20% of the original nominal list value.

Aircraft depreciation is not uniform. Values can rise during periods of tight supply, while major inspections or engine work can lower a specific aircraft’s price. Cabin upgrades, satellite communications, modern avionics, engine programs, and recent paint can support a higher valuation.

Readers comparing this aircraft with newer models can review the broader corporate jet cost range. New large-cabin jets often cost several times the current value of a Challenger 604.

Ownership, company payments

The FAA lists TVPX Aircraft Solutions as trustee rather than Karp or Palantir as the registered owner. Palantir’s regulatory filing supplies the economic-ownership detail by stating that Karp beneficially owns the executive aircraft. Aviation records then connect N814PS with Palantir’s operation.

Palantir says the aircraft arrangement is part of a security program based on an independent security study. The company reimburses Karp for some travel and purchases flight hours through the third-party operator for other trips. The audit committee reviewed the arrangement and its hourly rates.

The filing says the 2025 amount includes certain personal travel and travel with personal guests connected with the security program. It does not provide a public split between business flights, personal flights, positioning trips, or charges paid through each payment method.

The arrangement attracts investor attention because the annual expense exceeds the likely value of the aircraft by a wide margin and involves an asset beneficially owned by the chief executive. That does not establish that the rates were above market or that the travel lacked a business purpose. It shows why the purchase value and use expense must be reported separately.

Charter and fractional programs provide other ways to secure aircraft access without owning an entire jet. The cost of fractional jet access includes acquisition, management, and occupied-hour charges that differ from Palantir’s executive-aircraft agreement.

Who this estimate is useful for

Makes sense if

• You need the likely current value of N814PS.
• You distinguish an aircraft appraisal from company travel spending.
• You use $4.5 million to $6.5 million as a market estimate.
• You treat $17.2 million as Palantir’s 2025 use expense.

Doesn’t make sense if

• You call $17.2 million the purchase price.
• You assume the 2020 asking price was the completed sale amount.
• You treat estimated flight hours as verified logs.
• You ignore maintenance condition when valuing the aircraft.

The strongest current answer is that Karp’s identified 2002 Challenger 604 is probably worth about $4.5 million to $6.5 million. The $5 million to $6 million portion of that band is the most defensible working value based on the aircraft’s age, its 2020 listing, and live Challenger 604 market data.
