    I don't think there's any difference. "Upon" is perhaps a little formal or archaic, but I don't think it matters, in terms of meaning...
    Is there any difference at all between "depend on" and "depend upon"? Are there certain situations / contexts in which one or the other is more appropriate? Are there situations where one of the above should not be used?

    I don't really have a specific example in mind - it's just a general question. But an example could be: "Financial dealers' spreads depend on/upon the liquidity provided by the market."

    Thanks in advance.

    Edit: Thanks for your responses, and apologies for not seeing the previous thread; I did do a search but I must have overlooked it.

    The use of either preposition is optional in every context I can think of. I always use "on" with "depend".

    Here's a link to an old thread in which another member gave a similar answer:
