I'll research CBOE before writing the preview. Let me gather recent filings, transcripts, news, and price data.Let me read the most recent earnings materials and investigate the notable price moves (the May 1 jump and the early-June drop).Q1 was a blockbuster beat with a big guidance raise. But the stock had a dramatic ~20% collapse in early June. Let me investigate what drove that and gather recent news/analyst context.Let me get the latest 8-K on the credit facility and recent daily news, plus check quarterly volume/VIX context to frame Q2 expectations.I have strong context now. Let me quickly grab the year-ago (Q2 2025) headline figures to frame the YoY comparison, then write the preview.I now have what I need. Here's the preview.


Cboe Global Markets (CBOE) — Q2 2026 Earnings Preview

Reports before the open, Friday, July 31, 2026 | 2026Q2 Earnings Call

The one-line setup

Cboe heads into Q2 with all the momentum of a blockbuster Q1, a volatility-rich macro backdrop, and a stock that has round-tripped a huge swing. The debate isn't whether the quarter was good — it's whether management raises guidance again, how much of the realignment savings and Canada/Australia divestitures are landing, and how the event-contracts/prediction-markets narrative evolves. Expect a likely Q3 dividend hike to accompany the print.


1. Why the bar is high: the Q1 2026 blowout

The May 1 report reset expectations dramatically:

Metric Q1 2026 YoY
Net revenue $728.9M (record) +29%
Adjusted diluted EPS $3.70 (record) +48%
Adj. operating margin 72.4% +6.4pp
Adj. operating EBITDA $540.8M +41%

Growth was broad-based — record net revenue in every major category, with SPX options averaging ~4.9M contracts/day (a record) and a March monthly record of 5.4M. Crucially, management raised the full-year 2026 organic net revenue growth target to "low-double-digit to mid-teens" (from mid-single-digit), lifted Data Vantage to "low-double-digit," and cut adjusted opex guidance to $838–853M (from $864–879M). That combination — accelerating revenue + falling cost guide — is why the stock gapped up ~9% on the print.

Read-through for Q2: the comparison base is Q2 2025's $587.3M net revenue / $2.46 adjusted EPS. Given the volatility backdrop (below), the market is positioned for another quarter of strong double-digit YoY growth. After a raise like Q1's, "in-line" may not be enough to move the stock — investors will want a second guidance bump.


2. The macro tailwind: a genuinely volatile tape

Q2 (April–June 2026) spanned an unusually active risk environment, which is the single most important swing factor for Cboe's index-options and VIX franchises:

What to watch: whether Q2 SPX and VIX ADV set fresh records, and whether the non-0DTE/0DTE mix and index-options RPC (already $0.940 in Q1) held up. Higher index mix = higher blended RPC = operating leverage.

4. Guidance — the real event

This is the crux. After the aggressive Q1 raise, the questions are: 1. Does organic revenue guidance move up again from "low-double-digit to mid-teens," or does management hold given the tougher 2H comps? 2. Expense discipline — reaffirm/lower the $838–853M adjusted opex range? Q1 opex was only $200.9M (+4% YoY), well below run-rate, so there's room. 3. Data Vantage — any read on whether "low-double-digit" is conservative.


5. Strategic realignment — show me the progress

CEO Craig Donohue (one year in), COO Scott Johnston, and CFO Jill Griebenow have engineered an aggressive reshaping. Track updates on:

Net effect: a deliberate pivot from "bigger" to "sharper and higher-margin" — reallocating capital toward derivatives, clearing, and new growth areas.


6. Event/prediction markets & the SPX exclusivity question

The most important long-term narrative: - Securities-based event contracts (binary/vertical-spread structures on XSP/Mini-SPX) are pending regulatory approval, leveraging existing OCC-cleared, retail-broker-connected infrastructure. Phase 2 ambition: company-specific KPI contracts (e.g., earnings, subscriber, production, ad-revenue outcomes) — a potentially enormous TAM if realized. - Competitive/regulatory overhang: rivals (e.g., Kalshi-type venues) have launched S&P-500-linked binaries. Management argues broad-index binaries are inherently securities and is "optimistic" regulatory clarity protects its licensed products — but this is unresolved. - SPX exclusivity runs to 2032, and competitors are eyeing that window. Management leaned hard into the depth/breadth of the SPX ecosystem (11 floor-broker groups, 34 retail platforms, balanced flow, 58% of notional traded on the floor) as the moat. Any new color here matters. - Adjacent optionality: tokenization/atomic settlement and expanded US/Europe clearing (including securities-finance).

Bottom line

Cboe should report another strong, volatility-fueled quarter with wide margins. But after Q1's rare "raise revenue / cut costs" double, the market is essentially pricing in continued acceleration. The share-price reaction will likely be driven by (1) a second guidance raise, (2) a Q3 dividend increase, (3) tangible progress on realignment savings and the Canada/Australia closings, and (4) any regulatory/competitive news on event contracts and SPX — more than by the headline EPS beat itself.

Note: Figures above are drawn from Cboe's own filings/transcripts (Q1 2026 and Q2 2025 releases, recent 8-Ks) and market data; I did not have access to sell-side consensus estimates, so YoY comparisons are framed against the year-ago quarter ($587.3M net revenue / $2.46 adjusted EPS) and management's stated guidance rather than Street numbers.
