How We Got Our Top 100 Numbers

Why It Matters

The Top 100 provides a transparent benchmark of federal IT spend, helping contractors gauge market position and informing agencies about the most active vendors.

Key Takeaways

• Rankings use FPDS and USASpending data for FY 2024‑25
• Only prime contract dollars above $50k are counted
• About 350 PSC codes define eligible IT and telecom services
• M&A, subsidiaries, and joint ventures are consolidated in analysis
• Intelligence contracts and subcontracting dollars are excluded

Pulse Analysis

Washington Technology’s annual Top 100 list has become a benchmark for firms seeking federal IT, systems‑integration, professional‑services and telecom work. The publication builds its rankings on publicly available data from the Federal Procurement Data System and USASpending.gov, focusing on prime contract obligations that exceed $50,000 during the government’s fiscal year 2024‑25 (Oct 1 2024‑Sept 30 2025). By filtering roughly 350 product and service codes (PSCs) that describe IT‑related spend, the methodology isolates the contracts that truly drive the market, offering a data‑driven snapshot of who is winning the biggest deals.

The approach deliberately excludes classified intelligence spending and any subcontracting dollars, which means the list reflects only the visible portion of federal procurement. While this omission limits a full view of the total market size, it also protects sensitive information and keeps the rankings comparable across years. Adjustments for mergers, acquisitions, subsidiaries and joint ventures ensure that corporate structures do not fragment the underlying spend, giving a clearer picture of each parent company’s true market share.

For contractors, placement on the Top 100 serves as a credibility signal to both government buyers and private‑sector partners, often accelerating business‑development cycles and influencing pricing power. The transparent methodology allows firms to benchmark performance, identify gaps, and target growth areas such as emerging cloud or cybersecurity contracts that are captured within the PSC set. As the federal budget increasingly emphasizes digital transformation, companies that climb the rankings are likely to capture a larger slice of the $800 billion+ IT spend projected for the next decade.
