Hilbert Group AB has moved to deepen its institutional crypto footprint by acquiring Enigma Nordic AB, a Swedish digital asset trading firm known for its high-frequency, algorithmic execution capabilities, in a transaction valued at up to $25 million. The deal, disclosed on December 19, 2025, brings Enigma’s technology and trading operations fully under Hilbert’s control and is structured with performance-based earn-outs that link the final valuation directly to future trading results. Hilbert, which is listed on Nasdaq Stockholm under the ticker HILB B, described the acquisition as immediately accretive, underscoring that Enigma Nordic is already operating at scale and generating revenue rather than building toward a future commercial rollout.

Enigma Nordic enters the group with a track record that stands out even among institutional crypto operators. During 2025, the firm processed more than SEK 50 billion in crypto trading volume, a level of activity that places it firmly in the upper tier of professional digital asset trading desks. The platform specializes in low-latency, multi-venue execution across centralized exchanges, using automated strategies designed to capture small pricing inefficiencies rather than express outright views on crypto price direction. That approach has allowed the firm to remain active across a wide range of market conditions, including periods of sharp volatility and thinner liquidity, when discretionary trading strategies often struggle.

Hilbert’s management has been explicit that the acquisition is less about expanding crypto exposure and more about securing infrastructure capable of producing repeatable, risk-adjusted returns. The Enigma platform is built to operate continuously, with embedded risk controls that monitor exposure, drawdowns, and execution quality in real time. This system-driven model aligns closely with institutional expectations, particularly as allocators become more sensitive to operational risk and less willing to tolerate opaque trading processes. By folding Enigma into its existing operations, Hilbert gains the ability to deploy capital through systematic strategies that are largely agnostic to short-term crypto price swings while still benefiting from market activity reflected across major crypto price index benchmarks.

Operationally, Enigma Nordic will be fully integrated into Hilbert Group’s trading and asset management stack. The acquisition includes not only the technology but also the firm’s engineering and quantitative trading team, which will remain in place following the transaction. Hilbert indicated that the platform will support proprietary trading, managed crypto funds, and external institutional mandates, allowing the group to scale Enigma’s strategies across a broader capital base. Management also signaled plans to expand the system’s reach to additional trading venues and asset pairs, leveraging Hilbert’s balance sheet and investor relationships to increase throughput without fundamentally altering the strategy’s risk profile.

The timing of the deal reflects a broader shift in how institutions are approaching digital assets. As the overall coin market cap has grown and market structure has matured, returns have increasingly favored firms that can execute efficiently rather than those relying on directional bets. High-frequency and quantitative trading models have gained prominence as competition compresses margins and arbitrage opportunities become more fleeting. Hilbert’s move positions it closer to established digital asset market makers and quantitative trading houses, distancing the group from the perception of a traditional, long-only crypto investment firm.

Management commentary around the acquisition emphasized alignment and discipline. The earn-out structure was presented as a way to ensure that Enigma’s team remains focused on performance and execution quality after the transaction closes, while also protecting Hilbert from overpaying in a sector known for rapid shifts in profitability. Executives described Enigma’s trading history as “proven at scale,” highlighting the platform’s ability to function through multiple market regimes without relying on favorable price trends. That emphasis suggests a deliberate effort to attract institutional capital seeking exposure to digital asset markets without taking on the full volatility typically associated with crypto price movements.

From a market perspective, the acquisition underscores how institutional crypto strategies are evolving. Rather than chasing headline rallies or short-term narratives, firms like Hilbert are investing in infrastructure that treats digital assets as a market to be traded, not merely a speculative asset class. The Enigma deal illustrates how execution quality, automation, and risk management are becoming central differentiators as capital flows into more professionalized corners of the industry. As crypto price indices continue to serve as reference points for broader market performance, the ability to generate returns independent of those benchmarks is increasingly valued.

Hilbert’s acquisition of Enigma Nordic ultimately reflects a calculated bet on the next phase of digital asset markets. With crypto trading volumes remaining substantial even during periods of muted price action, management appears confident that infrastructure-led strategies can deliver consistent performance regardless of whether the broader crypto price environment is bullish or subdued. By anchoring its expansion around a platform that has already demonstrated scale and resilience, Hilbert is signaling that institutional participation in crypto is moving away from experimentation and toward systems built for longevity.
