In 2016, buying a single share of Amazon meant putting down roughly $750 at once, waiting days for a trade confirmation to fully settle, and paying a brokerage commission just for the privilege of clicking “buy.” A decade later, the same investor can put in $5, own a literal fraction of that share, pay zero commission, get the trade confirmed in seconds, and ask an AI assistant embedded directly in the trading app whether the position still makes sense. Investing in 2026 looks structurally different from investing a decade ago — not just in what’s popular, but in who can participate, how trades execute, and which asset classes were previously locked away from ordinary investors entirely. Here’s what actually changed, and what’s dominating portfolios right now.
The zero-commission revolution that reset the entire industry
The single biggest structural shift of the past decade traces back to one company: Robinhood, founded in 2013, which pioneered commission-free stock trading and forced the rest of the brokerage industry to follow by 2019. Before that shift, every trade at a traditional broker carried a fee — often $5-10 per transaction — which made frequent trading, small positions, and portfolio rebalancing genuinely expensive for anyone without significant capital. Fractional share trading, which Robinhood introduced in December 2019, removed the second major barrier: high-priced stocks like Amazon, Google, or Berkshire Hathaway became accessible with as little as $1, rather than requiring investors to buy an entire share outright.
The combined effect on participation has been measurable at a national level: U.S. stock market participation rose roughly 20% from 2013 to 2025, according to Gallup data, with 62% of Americans reporting some stock market investment by 2025 — a meaningfully broader base than existed a decade earlier, when equity ownership skewed far more heavily toward wealthier, older households.
A decade ago, buying into an IPO before the first day of public trading was reserved almost entirely for institutional investors and the ultra-wealthy — by 2026, several major retail platforms offer direct IPO access to ordinary account holders, a genuine structural shift in who gets first access to newly public companies.
AI is now embedded directly into how people research and trade
Ten years ago, “using AI to invest” meant, at best, a robo-advisor allocating your portfolio into a handful of pre-set index fund baskets based on a risk questionnaire. In 2026, AI has moved much deeper into the actual investing workflow. Major platforms now embed conversational research assistants directly into their apps — tools that can answer questions about a specific stock, summarize earnings calls, or flag portfolio risk in real time, rather than just executing pre-programmed rebalancing rules. Survey data from 2026 shows AI has become a meaningful part of how retail investors actually evaluate opportunities, though a notable share of investors — roughly a quarter — express concern about “market herding,” the risk of large numbers of investors all acting on the same AI-generated signals simultaneously and amplifying volatility rather than reducing it.
On the institutional side, the shift is even more structural: major asset managers are now using large language models and machine learning not just for research summaries but to build portfolio simulations and identify opportunities at a scale and speed that simply didn’t exist a decade ago, when quantitative strategies were the exclusive domain of specialized hedge funds with dedicated data science teams.
Tokenization: bringing traditional assets onto blockchain rails
This is arguably the most significant structural change of 2026 specifically, and it barely existed as a mainstream concept a decade ago. Asset tokenization — representing traditional securities like stocks, bonds, or funds as digital tokens on a blockchain — moved from a niche crypto experiment to genuine Wall Street infrastructure this year. In March 2026, Intercontinental Exchange, the parent company of the New York Stock Exchange, announced a strategic partnership with cryptocurrency exchange OKX specifically to bring tokenized NYSE-listed equities to crypto-native customers. Separately, major retail platforms have floated plans to let ordinary investors access tokenized private company shares — pre-IPO stakes historically restricted to accredited investors and institutions — a genuine democratization of an asset class that was completely locked away from retail investors a decade ago.
The practical draw of tokenization is straightforward: 24/7 trading instead of exchange hours, near-instant settlement instead of the traditional multi-day clearing process, and fractional ownership of assets that were previously sold only in large, indivisible blocks.
Private markets open up to everyday investors
A decade ago, private equity, private credit, and direct stakes in privately held companies were almost exclusively institutional territory — pension funds, endowments, and accredited high-net-worth individuals. That wall has been cracking steadily, and 2026 marks a clear acceleration: private credit in particular is growing rapidly among wealthy individual investors, driven by newer “evergreen” fund structures that allow ongoing entry and exit rather than the rigid multi-year lockups that defined older private equity vehicles. Major wealth management platforms report originating dozens of individual investment opportunities in private AI companies and data center infrastructure specifically for individual and family-office clients through dedicated private-markets platforms — a category of investing that essentially didn’t have a retail on-ramp ten years ago.
What’s actually “on top” in 2026
- AI infrastructure investing — direct and indirect exposure to data centers, chip supply chains, and power infrastructure supporting AI buildout has become one of the dominant retail and institutional themes of the year.
- Tokenized real-world assets — tokenized equities, funds, and even cash equivalents, with strong institutional emphasis on 24/7 markets and instant settlement.
- Private credit — evergreen fund structures giving individual investors access to lending markets previously reserved for institutions.
- Digital assets going mainstream — broader policymaker support and institutional adoption have pushed crypto further into standard portfolio conversations rather than remaining a speculative sideline.
- AI-assisted portfolio research — conversational AI tools embedded directly into brokerage platforms, used for real-time research and risk-flagging rather than static advice.
Comparing investing then and now
| Factor | ~2016 | 2026 |
|---|---|---|
| Trading commissions | $5-10 per trade at most brokers | Zero commission, industry standard |
| Minimum investment per stock | Full share price required | Fractional shares from $1 |
| Private market access | Institutional / accredited investors only | Expanding retail access via evergreen funds, tokenization |
| AI’s role | Basic robo-advisor allocation | Embedded conversational research, portfolio simulation |
| Settlement speed | T+2 or T+3 days (standard) | Near-instant on tokenized assets |
What hasn’t actually changed
Despite all the structural shifts, some fundamentals remain stubbornly the same. Broad, diversified index investing continues to outperform the majority of actively managed strategies over long time horizons, exactly as it did a decade ago — the tools for accessing markets have gotten dramatically easier and cheaper, but the underlying math of compound growth, diversification, and time-in-market hasn’t been rewritten by any amount of AI or tokenization. If anything, the ease of frictionless, zero-commission trading has introduced a new behavioral risk that didn’t exist at the same scale a decade ago: it’s now easier than ever to overtrade, chase short-term momentum, or react emotionally to daily volatility, precisely because the friction that used to slow investors down — commissions, minimum investment thresholds, multi-day settlement — has been engineered away.

Frequently Asked Questions
What was the biggest change in how ordinary people invest over the past decade?
The shift to zero-commission trading, pioneered by Robinhood starting in 2013 and standard across the industry by 2019, combined with fractional share investing introduced in 2019 — together these removed the two biggest cost barriers that historically kept smaller investors out of the market.
Is tokenization the same thing as cryptocurrency investing?
Not exactly — tokenization refers to representing traditional assets like stocks, bonds, or funds as digital tokens on a blockchain, which is a different concept from cryptocurrencies like Bitcoin, though the two trends are converging as traditional exchanges partner with crypto infrastructure providers.
Can everyday investors now access private equity and private credit?
Increasingly yes — newer “evergreen” fund structures and tokenized private-share platforms are opening access to asset classes historically reserved for institutional and accredited investors, though meaningful restrictions and higher risk profiles still typically apply compared to public markets.
How is AI actually being used in investing today, compared to a decade ago?
A decade ago, AI in investing largely meant basic robo-advisor portfolio allocation; in 2026, AI tools are embedded directly into trading platforms for real-time research, earnings summaries, and portfolio risk analysis, moving well beyond static, pre-set allocation models.
Has easier access to investing actually been good for average investors?
It’s mixed — broader access and lower costs have genuinely expanded market participation, but the removal of trading friction (commissions, minimums, settlement delays) has also made it easier to overtrade or chase short-term moves, a behavioral risk that didn’t exist at the same scale when trading carried more built-in cost and delay.
