How Tos or How To’s? Use “How-Tos” for Guides

If you mean more than one instructional guide, write “how-tos”: include the hyphen, but not an apostrophe. Between “how tos” and “how to’s,” neither is the standard dictionary form for that meaning.

Merriam-Webster lists how-to as a noun meaning a practical method, instruction, or something that provides instruction. Its plural example uses how-tos. It also lists how-to as an adjective meaning “giving practical instruction and advice.”

Which form fits your sentence?

Meaning	Form	Prediction-market example
One instructional piece	how-to	“Read this how-to before placing an order.”
Several instructional pieces	how-tos	“These how-tos explain prices and settlement.”
A description before a noun	how-to guide	“Start with a how-to guide to market rules.”
A phrase introducing an action	how to	“Learn how to read a prediction market.”

In “how-to guides,” the noun guides takes the plural ending. You do not need to write “how-tos guides.”

If how-tos feels awkward, guides, tutorials, or step-by-step instructions will often read more naturally.

When would an apostrophe belong?

An apostrophe can show possession; it does not form this noun’s ordinary plural. Purdue OWL’s apostrophe guidance distinguishes singular possessives formed by adding ’s from possessives of plurals ending in s, which take a final apostrophe.

Applied here:

• “The how-to’s example is clear.” One guide has an example.
• “The how-tos’ examples are clear.” Several guides have examples.

Those are grammatical, but “the example in the guide” and “the examples in the guides” are easier to read. “How to’s” is not the spelling to use for a collection of tutorials.

What a prediction-market how-to should explain

For this subject, clear instructions need more than a sequence of buttons. They should identify what counts as a winning outcome and show the cost of the order. Kalshi’s settlement guidance tells readers to check the rules for the official source and determination criteria—not simply assume that an event appearing to end means settlement is ready.

Here is a hypothetical example of useful how-to wording:

First check the named resolution source, deadline, and whether the threshold means “above” or “at least.” Assume this contract pays $1 for Yes and $0 otherwise, with no settlement fee. Suppose the Yes bid is 58¢ and the ask is 62¢, with enough quantity at each quote to fill 10 contracts. Buying 10 at the ask costs $6.20. With an assumed total entry fee of $0.10, you spend $6.30. A Yes settlement pays $10, leaving $3.70 net; a No settlement loses the $6.30 spent. Selling immediately at the unchanged bid returns $5.80—a $0.50 loss before any exit fee.

That example belongs in a how-to. A collection of guides containing examples like it is a collection of how-tos. For a fuller market-reading sequence, use the pre-trade checklist.
