Quantum-Resistant Secure Chat Software Development Kit Market Report 2025

The quantum-resistant secure chat software development kit (SDK) market size has grown exponentially in recent years. It will grow from $0.82 billion in 2024 to $1.08 billion in 2025 at a compound annual growth rate (CAGR) of 32.2%. The growth during the historic period is driven by enterprises placing greater emphasis on communication security, the initial uptake of encrypted chat platforms, an increase in targeted cyberattacks on messaging applications, heightened awareness of quantum computing threats, and a rising demand for privacy-focused communication tools.

The quantum-resistant secure chat software development kit (SDK) market size is expected to see exponential growth in the next few years. It will grow to $3.28 billion in 2029 at a compound annual growth rate (CAGR) of 31.9%. The growth expected during the forecast period is driven by the expansion of secure messaging for cross-border operations, increasing regulatory demands on data privacy, rising investments in quantum-safe communication technologies, the surge in remote and hybrid work environments, and growing demand from military and defense sectors. Key trends in this period include the development of lightweight encryption protocols, real-time threat detection systems, the integration of blockchain for identity verification, incorporation with zero-trust architectures, and advancements in secure group messaging protocols.

The increasing number of cyberattacks is expected to drive significant growth in the quantum-resistant secure chat software development kit (SDK) market. Cyberattacks, which involve deliberate and malicious attempts to breach, disrupt, or gain unauthorized access to computer systems, networks, or data, are becoming more frequent due to rising digitalization and expanding online connectivity. This increased digital activity creates more vulnerabilities that attackers can exploit. Quantum-resistant secure chat SDKs help prevent such attacks by incorporating encryption methods designed to withstand threats from quantum computing, making them ideal for securing sensitive communications. By enabling end-to-end protection, these SDKs reduce the risk of data breaches and enhance the safety and reliability of messaging applications. For example, the Australian Cyber Security Centre reported over 94,000 cybercrime incidents in 2022-2023, a 23% increase from the previous year, highlighting the urgent need for stronger security measures. Consequently, the growing number of cyberattacks is fueling demand for quantum-resistant secure chat SDKs, driving market expansion.

Leading companies in the quantum-resistant secure chat software development kit (SDK) market are investing in innovative solutions such as post-quantum cryptography-based messaging frameworks to protect communications from future quantum-enabled cyber threats. These frameworks employ encryption algorithms specifically designed to resist decryption attempts by powerful quantum computers. For example, in June 2025, Finland-based Streamr AG released version 103.0 of its Streamr SDK, featuring a quantum-resistant security stack. This update incorporates ML-DSA-87 for identity and signatures, ML-KEM-1024 combined with HKDF and AES-256 for key exchange, and AES-256 for end-to-end encryption. The new SDK allows developers to implement quantum-safe cryptography in chat and messaging systems by selecting ML-DSA identities for sign-and-encrypt operations. It is particularly suited for real-time data or chat environments where long-term confidentiality is essential, such as finance, healthcare, and defense sectors. This development underscores the growing demand for SDKs that integrate post-quantum cryptography standards, driving companies to create tools that help businesses upgrade their cryptographic infrastructure ahead of emerging quantum threats.

In February 2025, Mattermost Inc., a US-based open-source software company, partnered with Qrypt Inc. to develop a quantum-secure, end-to-end encrypted collaboration platform. This collaboration is designed to protect sensitive communications in defense, intelligence, and critical infrastructure sectors from emerging cyber threats and future quantum computing risks. Qrypt Inc., a US-based cybersecurity firm, provides a quantum-resistant secure chat software development kit (SDK) that integrates quantum-secure encryption into messaging applications, strengthening the platform’s security against quantum-enabled attacks.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.
