Executive Summary
The Trade Desk delivered 18% revenue growth to $2.9 billion with operating margin expansion to 20%, driven by 11% growth in gross spend and increased adoption of value-added services. Operating cash flow surged 34% to $993 million, supporting $1.4 billion in share repurchases.
What happened
The Trade Desk generated $2.9 billion in revenue for the year ended December 31, 2025, an 18% increase from $2.4 billion in 2024. The growth was driven by 11% expansion in gross spend on the platform to $13.4 billion, increased client adoption of value-added services and data features (including enhancements from Kokai and other platform features), and higher platform fees. Revenue earned from gross spend fluctuated due to changes in service mix, client and channel composition, and the amount of supplier-provided component costs recorded as revenue reductions versus platform operations expenses. Income from operations increased $162 million to $589 million, with operating margin expanding to 20% from 17%. The improvement reflects operating leverage as revenue growth of 18% outpaced total operating expense growth of 14%. Net income rose 13% to $443 million, while the effective tax rate increased to 33% from 23%, primarily due to lower tax benefits associated with stock-based awards ($9 million in 2025 versus $73 million in 2024). Operating cash flow surged 34% to $993 million, driven by net income adjusted for non-cash items of $1.3 billion, partially offset by a $433 million increase in accounts receivable reflecting business growth and timing of client collections. The company paid $1.4 billion to repurchase 26.2 million shares of Class A common stock during the period. As of December 31, 2025, the company held $658 million in cash and cash equivalents and $645 million in short-term investments, with $445 million available under its credit facility.
Why it matters for investors
The results demonstrate The Trade Desk's ability to capture increasing value from its programmatic advertising platform while maintaining strong operational efficiency. The 18% revenue growth on 11% gross spend growth indicates the company successfully drove higher monetization through increased adoption of value-added services, data offerings, and platform fee expansion. The 300 basis point operating margin expansion to 20% shows operating leverage is materializing as the company scales. However, the 31% increase in platform operations expense, driven primarily by $123 million in higher hosting costs, highlights the capital intensity required to support growing query volume, AI capabilities, and new technical features. Management noted rising prices for data center components, creating uncertainty around future infrastructure costs. The company capitalized $13 million in software development costs during 2025 and expects platform operations expense to continue increasing in absolute dollars. The effective tax rate increase to 33% from 23% significantly impacted net income growth, which lagged operating income growth. The reduction in tax benefits from stock-based awards and changes from the One Big Beautiful Bill Act (OBBBA) enacted July 2025 contributed to the higher rate. While the OBBBA did not materially impact 2025 results, it allowed accelerated deduction of research and development costs, resulting in $175 million recorded as income taxes receivable. Strong cash generation enabled aggressive capital return, with $1.4 billion deployed to share repurchases (including $10 million in excise tax). The company's dual-class structure gives Class B holders (including executives, employees, and directors) approximately 49.9% voting power despite economic dilution from repurchases.
Bullish points
Revenue growth of 18% exceeded gross spend growth of 11%, indicating successful monetization expansion through increased adoption of value-added services, data offerings, and higher platform fees, creating a natural flywheel effect as Kokai and other platform enhancements drove client value capture.
Operating margin expanded 300 basis points to 20% from 17%, demonstrating operating leverage as the business scales and revenue growth outpaced operating expense growth of 14%, with management expecting this leverage to support future long-term profitable growth.
Operating cash flow surged 34% to $993 million despite working capital headwinds from a $433 million accounts receivable increase, providing substantial financial flexibility to fund $1.4 billion in share repurchases, capital expenditures of $197 million, and $13 million in capitalized software development.
Adjusted EBITDA increased 18% to $1.2 billion, matching revenue growth and indicating the core business profitability remained strong despite significant investments in hosting infrastructure, AI capabilities, and platform development to support future growth.
Bearish points
Effective tax rate increased to 33% from 23%, significantly constraining net income growth to 13% despite 38% operating income growth, primarily due to lower tax benefits from stock-based awards ($9 million in 2025 versus $73 million in 2024) and unfavorable changes in tax jurisdiction mix.
Platform operations expense increased 31% to $619 million, with $123 million driven by higher hosting costs to support query volume and AI features, reflecting rising capital intensity and exposure to increasing data center component prices with uncertain timing and duration.
The company faces concentration risk as two holding companies each represented more than 10% of gross billings when individual agency relationships are aggregated, though contracts and billing relationships remain at the agency level, and management noted that sequential liability arrangements with agencies increase credit risk.
Working capital consumed $275 million during 2025, with accounts receivable increasing $433 million due to business growth and collection timing, while the company typically pays suppliers in advance of client collections, creating ongoing working capital pressure as the business scales.
Key highlights
The Trade Desk operates a global advertising technology platform enabling ad buyers to create, manage, and optimize digital advertising campaigns across ad formats, channels, and devices. The company generates revenue by charging clients a platform fee generally based on a percentage of total spend, plus fees for value-added services and data. Revenue is reported net of amounts paid to suppliers for advertising inventory and supplier-provided components. For the year ended December 31, 2025, gross spend on the platform totaled $13.4 billion, up 11% from $12.0 billion in 2024. Revenue of $2.9 billion represented approximately 21.6% of gross spend in 2025, compared to 20.3% in 2024. The increased revenue capture reflects higher utilization of value-added services and data, platform fee increases, and changes in service and client mix. Total operating expenses increased 14% to $2.3 billion, with platform operations rising 31% to $619 million, sales and marketing up 18% to $644 million, technology and development up 13% to $525 million, and general and administrative down 3% to $518 million. The general and administrative decline was driven by a $48 million decrease in stock-based compensation related to the CEO Performance Option, which follows a graded-vesting attribution method and is expected to be fully recognized by the first quarter of 2026. The company held $658 million in cash and cash equivalents and $645 million in short-term investments as of December 31, 2025. With no outstanding debt balance under the credit facility maturing June 2026 and $445 million available for borrowing, management believes liquidity is sufficient for at least the next 12 months. Capital expenditures totaled $197 million in 2025, focused on data center computing and networking equipment to support hosting capabilities and growing AI functionality.
Management commentary
Management identified key growth opportunities including ongoing global expansion, continuing development of omnichannel ad inventory (particularly CTV and other video, mobile, and audio), optimization of data usage and measurement capabilities, adoption of third-party retail data and first-party data by clients, and continued development and incorporation of AI. Management stated: "We believe that growth of the programmatic advertising market is important for our ability to grow our business. Adoption of programmatic advertising by advertisers allows us to acquire new clients and grow revenue from existing clients." Regarding the competitive environment, management noted: "In 2025, the global digital advertising ecosystem saw a large increase in supply (ad impression opportunities). Supply growth has meaningfully outpaced demand growth. Overall, we believe this is a positive development for us. This continues to shift the balance of power to the buy-side and the objectivity of our position (by not owning media) is more valuable in this strengthening buyer's market." However, management acknowledged incremental risks, stating the distress on the sell-side "has in cases lowered costs per impressions ('CPMs') for sellers and publishers and has in some cases (especially for non-premium sellers and publishers) also lowered their fill-rates in addition to CPMs charged." Management emphasized planned investments: "We invest for long-term growth. We anticipate that our operating expenses will continue to increase in the foreseeable future as we invest in platform operations for our hosting capabilities as well as technology and development to enhance our platform and related offerings, including our continued focus on the development and incorporation of AI." Regarding profitability, management stated: "We believe that these investments will contribute to our long-term growth, although they may negatively impact profitability in the near term. Our business model has allowed us to grow significantly, and we believe that our operating leverage enables us to support future long-term growth profitably."
What to watch next
Investors should monitor:
Platform operations expense trajectory as management expects continued increases in absolute dollars to support query volume growth, AI and machine learning capabilities, and new technical features, with exposure to rising and inelastic data center component prices due to high infrastructure demand creating cost uncertainty.
Effective tax rate volatility given the significant increase to 33% in 2025 from 23% in 2024, with management noting the rate may be affected by timing and volume of stock-based award exercises (subject to stock price fluctuations), changes in tax laws including impacts from the One Big Beautiful Bill Act, and international tax developments including OECD Pillar Two minimum tax rules.
Client concentration and sequential liability risk as two holding companies each represented over 10% of gross billings when aggregated, though individual agency relationships remain separate, and many agency contracts provide that if advertisers don't pay agencies, agencies are not liable and the company must seek payment solely from advertisers.
Regulatory and privacy law compliance costs as the company noted "adapting our business to enhanced and evolving privacy obligations across relevant jurisdictions could continue to involve substantial expense and may cause us to divert resources from other aspects of our operations," with particular focus on state privacy laws requiring opt-out signal support (like Global Privacy Control) and heightened scrutiny of health and children's data.
