TradeTech 2026: Key insights shaping Europe's financial markets

The European market needs better visibility

One theme kept coming up: Europe's fragmented markets need more transparency. The "Consolidated tape" is important not only for transaction transparency and analytical tools, but also for providing visibility into the real liquidity of European markets. What struck us was that useful data currently inaccessible to retail investors, such as flow distribution, could open up new opportunities for both retail and non-retail clients.

This is both a data and competitiveness issue, because when the market lacks transparency, everyone loses.

The 24/5 trading debate

The conference hosted a lively debate on whether Europe should adopt round-the-clock trading. In some countries, half of trading volumes are concentrated in the final hour due to US market overlap. The arguments for 24/5 trading were compelling: democratizing access to liquidity for international investors and those outside traditional trading hours. Yet the counterarguments were equally strong: concerns about illiquidity during off-hours, market volatility, and whether this truly benefits the real economy or erodes the trust in the markets.

Tellingly, a major objection emerged: what works on fragmented American markets isn't possible on fragmented European markets, and European markets first need structural reforms. The final poll reflected this skepticism, with 78% voting against 24/5 adoption.

AI augmenting the trading operations

One of the most forward-thinking sessions explored the partnership between human traders and AI. While overall performance is roughly equivalent, AI demonstrates more reduced variance. But here's the nuance: machines excel at complex calculations, unlimited information processing, and optimization within datasets, while humans bring rapid learning, comprehension, creativity, and ideas beyond the dataset.

The takeaway? The real innovation lies in creating "cyborgs" - integrated human-AI systems where machines handle computation and prediction speed, while humans provide strategy, creativity, and final decision-making.

The IPO market crisis calls for pragmatic solutions

The European IPO market faces real competition, not just from major global exchanges, but from private equity. What's the disconnect? On the investor side, there's abundant liquidity (often sitting in cash) that's underinvested. On the issuer side, private equity offers speed that traditional IPOs struggle to match.

Rather than fighting this trend, the conversation shifted toward creative solutions: using stock exchange infrastructure for private equity securities, but with private equity's protective rules around buyer/seller control and pricing transparency.

The closing auction puzzle

Here's an interesting finding: over the past five years, trading volumes have heavily shifted toward the closing auction mechanism, with 30-40% of closing liquidity concentrated at fixing, and remarkably, 50% of that liquidity appearing in just one minute, and 75% within two minutes.

This extreme concentration creates real challenges, especially for professional portfolio adjustments across fragmented European venues. Some markets are already rethinking their fixing methodology, but this remains an area where better tools and clarity are needed.

European retail: bigger than you think

Finally, a pleasant surprise: Europe's retail market is larger than commonly assume - around €9 billion per day in Q1 2026 and growing. There's been a 50% increase over the past two years, though fragmentation across national markets remains a challenge.

What this means for us

These conversations reinforce what we've always believed: Europe's financial infrastructure has enormous potential, but it requires better integration, transparency, and tools. Whether it's consolidated data, human-AI collaboration, or solving the closing auction puzzle, the path forward involves building infrastructure that's both technically sophisticated and pragmatically designed for the real needs of traders and investors. Because markets are evolving faster than ever, the question is whether we can build the infrastructure to support that evolution.
