10 Market Structure Trends to Watch in 2026: AI, Prediction Markets, and the Private Credit Reckoning
Introduction: The Great Inflection
2026 arrives on the heels of a record-shattering 2025 in trading volumes, with global equities, fixed income, and derivatives all posting double-digit growth. A new regulatory regime under the SEC and CFTC has begun reshaping the landscape, signaling both deregulation in mature areas and heightened scrutiny in fledgling ones. Ten distinct trends are now converging to redefine how capital markets operate—from the limited but expanding role of artificial intelligence in live trading to the explosion of event contracts that have turned prediction markets into a multibillion-dollar ecosystem.
This is not a fast analysis of headlines. It is a slow audit of structural shifts that institutional readers—hedge funds, asset managers, broker-dealers, and exchange operators—must absorb to navigate the year ahead. Drawing on proprietary data and expert insights from leading analysts at Coalition Greenwich, we unpack the critical forces that will determine winners and losers in 2026.

1. AI Disrupts Research, Ignores Trading (For Now)
The AI hype cycle has been relentless, but its impact on market structure remains uneven. Hedge funds and proprietary trading firms have employed machine learning for years, mostly for signal generation and risk modeling. Yet actual execution—order routing, smart order routing, liquidity detection—remains deterministic. AI is not replacing algorithms in 2026; it is augmenting the humans who design them.
The real disruption is in research. AI tools now excel at digging into unstructured data—earnings call transcripts, satellite images, social media sentiment, even Web3 blockchain analytics. This allows analysts to generate code for backtesting strategies in minutes instead of weeks. Broker-dealers and asset managers remain cautious, however, citing regulatory uncertainty around model governance and explainability. A senior quant at a top-tier bank told us, “We trust AI to find correlations, but we don’t trust it to execute a trade.”
As Daniel J. Connell of Coalition Greenwich puts it: “New technologies often become overhyped in their early years. AI is not one of them. The adoption curve is real, but it will take years before AI touches the trading desk directly.”

2. Regulatory Reduction: A Double-Edged Sword
Both the SEC and CFTC have pledged to reduce the regulatory burden while providing clarity in emerging areas such as digital assets, event contracts, and market data fees. This deregulation spurs innovation: we are already seeing new product launches that would have been unthinkable two years ago, including leveraged crypto ETFs and broad-based prediction market futures.
But deregulation also opens new risk channels. The collapse of a midsized private credit fund in early 2026 served as a stark reminder that lighter oversight can invite systemic vulnerabilities. As Kevin McPartland of Coalition Greenwich warns, “We’re keeping a cautious eye out for speeding cars. Innovation is great, but markets need guardrails.”
The tension between fostering innovation and maintaining stability will define regulatory debates throughout 2026. Expect more Congressional hearings on the risk of “regulatory arbitrage” between venues and products.

3. Prediction Markets Go Mainstream
What began as a niche curiosity on platforms like Kalshi and Polymarket has become a mainstream asset class. In 2026, the CME, Cboe, ICE, Interactive Brokers, and Robinhood have all launched or expanded their event contract offerings. A futures contract now exists for nearly anything with an uncertain outcome—from U.S. presidential elections to hurricane landfalls, Federal Reserve rate decisions, and even box office revenues.
Institutional traders are beginning to use these markets not just for speculation but for hedging macro exposure and generating alpha. A large hedge fund recently used a basket of prediction contracts to delta-hedge its political risk ahead of a contested election. The liquidity is still thin compared to traditional futures, but volumes are growing at 40% month-over-month.
The year may also bring consolidation as exchanges compete to dominate the “event contract” space. Clear regulatory guidance from the CFTC—expected later this year—will likely accelerate the trend.

4. Private Credit: The Froth Clears
The private credit market, which ballooned to nearly $2 trillion in assets, is entering a long-anticipated washout. After years of easy money and loose underwriting, several direct lending funds have been forced to mark down assets as interest rates stay higher for longer. The failure of a major middle-market lender in late 2025 sent shockwaves through the industry, prompting a re-evaluation of risk models.
In 2026, we are seeing consolidation as stronger managers acquire distressed funds at a discount. Institutional investors are demanding greater transparency—more frequent valuations, better covenants, and standardized reporting. The shift is also benefiting traditional banks, which are selectively stepping back into the leveraged loan space as private credit pulls back.
The froth is clearing, but the hangover will last. “Private credit was marketed as a safe alternative to bank loans,” says a Coalition Greenwich analyst. “Now we’re learning what ‘safe’ really means when liquidity dries up.”

5. Bond Trading Venue Competition Finally Delivers Real Benefits
For years, the bond market’s shift to electronic trading was a slow burn. In 2026, the competition among bond trading venues has become fierce, and investors are reaping the rewards. New platforms like Tradeweb’s automated execution, MarketAxess’s all-to-all pools, and Bloomberg’s B-PIPE have driven down spreads and improved execution quality.
The biggest change is in corporate bonds. Request-for-quote (RFQ) protocols are being complemented by central limit order books and portfolio trading systems that allow investors to trade dozens of bonds in a single click. Liquidity in high-grade credit has improved by an estimated 15% year-over-year, according to Coalition Greenwich data.
The push for even greater efficiency is now reaching municipal bonds and emerging market debt, where fragmentation remains high. We expect at least one major venue merger in 2026 as platforms seek scale to compete on data and analytics.

6. Tokenization Finds Its Killer App in On-Chain Yield
Tokenization of real-world assets has been a buzzword for years, but 2026 marks the year it finds a genuine killer application: on-chain yield products. By putting Treasury bills, money market funds, and short-term credit on public blockchains, issuers can offer near-instant settlement and programmatic lending.
BlackRock’s BUIDL fund, Franklin Templeton’s BENJI, and a host of new entrants now manage over $50 billion in tokenized assets. The real breakthrough is in collateral management: firms can post tokenized Treasuries as margin on crypto exchanges or even in traditional derivatives clearing. This is reducing friction and unlocking liquidity that was previously trapped in legacy settlement cycles.
Yield is the hook. Investors can earn 4–5% on tokenized T-bills and use those tokens as collateral to earn additional yield in DeFi lending pools. The risk? Smart contract bugs and the regulatory status of these wrappers remain uncertain. But the momentum is undeniable.

7. Disintermediation: Banks and Brokers Tread Carefully
The digital asset revolution, prediction markets, and tokenization all point toward a future where intermediaries are bypassed. But banks and brokers are not standing still. In 2026, they are cautiously navigating disintermediation by becoming the trusted providers of custody, compliance, and liquidity.
State Street now offers digital asset custody alongside traditional fund administration. JPMorgan’s blockchain-based repo platform has processed over $1 trillion in transactions, effectively turning the bank into a settlement layer for wholesale funding. Meanwhile, independent broker-dealers are scrambling to offer their own tokenization or event contract services to avoid losing clients to incumbent exchanges.
The challenge is balancing innovation with risk. Many firms have built “wait-and-see” teams. But as revenues from traditional activities (equities, fixed income) compress, the pressure to disintermediate—or be disintermediated—will only intensify.

8. Equity Market Structure Renaissance Continues to Gather Pace
The equity market structure reforms that began in the mid-2020s are now bearing fruit. The SEC’s tick size pilot and order routing transparency rules have increased competition for retail order flow. Brokers are routing more orders to alternative trading systems (ATS) and internalizers, narrowing spreads for retail investors.
The big story in 2026 is the revival of periodic auctions and conditional order types. These are enabling institutional block trading without market impact, even in mid-cap names. Exchanges are promoting cycle-based auctions that allow large orders to cross at the mid-price. Volume in these mechanisms has doubled in the past year.
Looking ahead, the next frontier is in “offboard” equities trading—stocks listed on foreign exchanges but traded locally. The trend toward 24/7 trading (see next section) may blur the line between primary and secondary listings.

9. The Push for 24/7 Trading Gains Momentum
After the launch of 24-hour trading on certain crypto and U.S. equity platforms, 2026 sees a broader push for round-the-clock markets. Nasdaq, Cboe, and NYSE have all announced extended-hours pilots for at least a subset of stocks. The logic: global investors increasingly demand the ability to react to overnight news without waiting for a single opening auction.
But the shift is not without friction. Clearing and settlement still operate on a T+1 cycle in most jurisdictions, creating a mismatch between continuous trading and batch settlement. LPs worry about managing risk in thin liquidity hours. Some asset managers have pushed back, arguing that 24/7 trading advantages high-frequency traders over long-term investors.
Despite these challenges, several regional exchanges in Asia and Europe are now coordinating their opening times to create a near-continuous 18-hour window. The momentum suggests that by 2027, at least one major index will trade on a 23/5 schedule.

10. Data Monetization and Market Transparency: The Next Frontier
The final trend is less visible but equally transformative: how market data is priced and distributed. Regulators in the U.S. and Europe are pushing for lower fees and better access to real-time consolidated data. The SEC’s market data infrastructure modernization plan is forcing exchanges to unbundle proprietary data from trading services.
This is opening opportunities for independent data vendors to compete. Firms like Bloomberg, Refinitiv, and a new wave of fintech data providers are offering cheaper, faster feeds that combine exchange data with alternative data sets. The battleground is latency—one major broker recently upgraded its connectivity to shave 50 microseconds off its data feed.
Meanwhile, the growth of tokenization and on-chain markets has created a new category of “on-chain data” that needs to be normalized and fed into traditional risk systems. Data is no longer just a cost center; for exchanges and brokers, it is becoming a profit center.

Conclusion: Structure as Strategy
The ten trends outlined above are not isolated phenomena. They are interlocking forces that collectively redefine the architecture of capital markets. AI will transform research before it touches execution. Prediction markets will challenge the monopoly of traditional derivative exchanges. Private credit’s reckoning will reshape credit intermediation. Tokenization will blur the line between on-chain and off-chain. And regulators will walk a tightrope between innovation and stability.
For institutional participants, the imperative is clear: invest in technology, partner strategically, and stay informed. Those who treat market structure as a static backdrop will be left behind. Those who see it as a dynamic strategy will thrive.
