Block's Profitability Surge Outshines PayPal as AI-Fueled Efficiency Drives Beat

Block's Q1 earnings beat estimates as cost cuts and AI tools boost margins, widening valuation gap over PayPal. Stock jumps 6.7%, with raised guidance signaling continued growth.

Jack Dorsey’s Block has delivered a first-quarter earnings surprise that underscores how aggressively it is pulling away from legacy rival PayPal. The fintech disruptor posted adjusted earnings per share of $0.85, comfortably ahead of the Street’s $0.68 consensus estimate, on revenue of $6.06 billion. The result triggered a 6.7% share price jump to $74.85 over the following five trading days, extending a 21% rally over the past month and widening Block’s valuation gap over its larger competitor to roughly $44.5 billion versus PayPal’s $40.7 billion.

The outperformance is rooted in a dramatic operational overhaul. Block slashed its workforce by 40% in 2025 and replaced many roles with automated AI tools, a move that expanded its adjusted operating margin to a record 25%. That margin leverage helped boost gross profit by 27% year over year in the first quarter, with the Cash App segment alone contributing $1.91 billion—a 38% jump. The consumer platform now boasts 59 million monthly active users, a 4% increase, and is evolving from a peer-to-peer payments app into a full banking and credit ecosystem, aided by AI-driven lending.

Block’s Bitcoin holdings, at 28,355 BTC, remain a double-edged sword. A fair-value impairment charge of $173 million weighed on the headline numbers in the quarter, but the company’s strategic positioning in crypto continues to attract investor interest. Dorsey is doubling down on artificial intelligence with new productivity tools such as “Moneybot” and “Managerbot,” aiming to further automate financial services and sustain margin expansion.

The management team raised its full-year 2026 gross profit guidance to $12.33 billion, implying 19% growth, and set an earnings per share target of $3.85. That trajectory has earned Block a PEG ratio of 0.62—well below the industry average of 1.45—suggesting the stock remains undervalued relative to its projected earnings growth of 31% through 2027. The forward price-to-earnings multiple of 19.4x, while higher than many fintech peers, is supported by a Rule-of-40 score of 52%, compared to PayPal’s 23%.

Wall Street’s response is split but leans bullish. Goldman Sachs pins a $95 price target on the stock, and Citi goes as high as $100. Piper Sandler remains cautious with an Underweight rating, questioning the durability of the margin expansion. Insider sales of $6.85 million over the past 90 days appear largely tax-driven given the stock’s 26.5% quarterly climb. Meanwhile, PayPal trades at just 8.3 times forward earnings with a free-cash-flow yield of 16.7%, but its branded checkout growth has slowed to a paltry 2%, and analysts have slashed their average price target from $65.83 to $57.04 in recent months.

The contrast between the two payment giants could not be starker. Block has completed a painful transformation into a leaner, AI-driven growth machine, while PayPal is leaning heavily on share buybacks—a $15 billion program approved in February—to prop up its stock. Without a structural catalyst to reverse market share losses to Apple Pay and regional wallet providers, PayPal’s low valuation may remain a value trap rather than an opportunity.

Investors face a straightforward choice: buy Block for its operational momentum and margin expansion, or buy PayPal for its capital returns and cheap multiple. The first quarter’s results suggest the market’s preference is already clear.
